# Red Bear OS Comprehensive Boot Improvement Plan
|
||||||
|
|
||||||
|
**Version**: 2.0 — 2026-05-16
|
||||||
|
**Status**: Active
|
||||||
|
**Supersedes**: `SMP-BOOT-HARDENING-PLAN.md` v1.0 (P15 section) for forward work
|
||||||
|
**Scope**: Kernel SMP, AP startup, x2APIC, per-CPU data, TLB shootdowns, IRQ routing, scheduler, userspace boot, daemon robustness, IPC hardening.
|
||||||
|
|
||||||
|
## Assessment Summary
|
||||||
|
|
||||||
|
Three parallel deep-dives completed:
|
||||||
|
1. **Kernel SMP**: 20 source files, cross-referenced with Intel SDM, AMD APM, ACPI 6.5
|
||||||
|
2. **Userspace boot**: 22 source files across init, acpid, pcid, pcid-spawner, driver-manager, IPC
|
||||||
|
3. **Modern specs**: Intel SDM Vol 3A Ch 8, AMD64 APM Vol 2 Ch 7, ACPI 6.5, Linux smpboot.c, Zircon lk_main
|
||||||
|
|
||||||
|
**Total issues: 38 kernel + 16 userspace (from v1.0) + 29 new userspace + 8 new kernel = 91 issues**
|
||||||
|
- Critical: 6 kernel + 3 userspace = 9 (original) + deferred P15-3, P15-5
|
||||||
|
- High: 9 kernel + 4 userspace = 13
|
||||||
|
- Medium: 12 kernel + 12 userspace = 24
|
||||||
|
- Low: 15 kernel + 17 userspace = 32

## New Findings (This Assessment)

||||||
|
|
||||||
|
### New Kernel Issues
|
||||||
|
|
||||||
|
| # | Severity | Issue | File | Detail |
|
||||||
|
|---|----------|-------|------|--------|
|
||||||
|
| K39 | High | xAPIC path has NO delay between INIT and first SIPI | `madt/arch/x86.rs:195-218` | Intel SDM requires 10ms. Only x2APIC path has spin-count delays. xAPIC path sends INIT then immediately sends SIPI. |
|
||||||
|
| K40 | Medium | No ESR clear/check during AP startup | `madt/arch/x86.rs` | `esr()` method exists in local_apic.rs but never called during AP bringup. Intel SDM: clear ESR before SIPI, read after to verify acceptance. |
|
||||||
|
| K41 | Low | Sequential AP startup only | `madt/arch/x86.rs` | Linux does parallel bringup for 96+ cores. Current code starts APs one-by-one. |
|
||||||
|
| K42 | Low | No cpu_callout_mask / cpu_callin_mask handshake | `madt/arch/x86.rs` | Linux uses two-phase handshake for AP validation. Current code uses AP_READY bool only. |
|
||||||
|
| K43 | Medium | xAPIC SIPI has spurious bit 14 (Level=Assert) | `madt/arch/x86.rs:209` | ICR value 0x4600 has bit 14 set. Per Intel SDM, this bit is reserved/zero for SIPI. Works in QEMU but may cause issues on real hardware. |
|
||||||
|
| K44 | Low | No self-IPI MSR optimization | `local_apic.rs` | Self-IPI via MSR 0x83F is the fastest single-IPI path for x2APIC. Not implemented. |
|
||||||
|
| K45 | Low | No CPUID topology detection for AMD | `local_apic.rs` | CPUID leaf 0x8000001E for AMD topology (ext_apic_id, core_id, node_id) not used. |
|
||||||
|
| K46 | Low | xAPIC path missing second SIPI | `madt/arch/x86.rs:206-218` | Only x2APIC path sends second SIPI. Intel SDM recommends sending SIPI twice for compatibility. |
|
||||||
|
|
||||||
|

## Improvement Plan — Patch Series
|
||||||
|
|
||||||
|
### Phase 1: Stabilize SMP Boot (P16) — 6 patches
|
||||||
|
|
||||||
|
**Goal**: Make AP startup reliable on real hardware with calibrated timing, error checking, and firmware bug detection.
|
||||||
|
|
||||||
|
#### P16-1: TSC-Calibrated SIPI Delays (High K7, K39, K43, K46)
|
||||||
|
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Changes**:
|
||||||
|
1. Add `udelay(us: u64)` function using TSC (read via `rdtsc`, calibrated from `cpu_khz` if available, else use known CPU frequency). For early boot before TSC calibration, use a conservative spin loop.
|
||||||
|
2. **xAPIC path** (currently no delay):
|
||||||
|
- After INIT IPI: `udelay(10_000)` (10ms per Intel SDM)
|
||||||
|
- After SIPI #1: `udelay(200)` (200µs)
|
||||||
|
- Send SIPI #2 (currently missing)
|
||||||
|
- After SIPI #2: `udelay(200)` (200µs)
|
||||||
|
3. **x2APIC path** (currently spin-count delays):
|
||||||
|
- Replace `for _ in 0..100_000 { spin_loop() }` with `udelay(10_000)` (10ms)
|
||||||
|
- Replace `for _ in 0..2_000_000 { spin_loop() }` with `udelay(200)` (200µs)
|
||||||
|
4. Fix xAPIC SIPI ICR: change `0x4600` to `0x0600` (remove spurious bit 14 Assert)
|
||||||
|
|
||||||
|
**Early-boot TSC strategy**: At AP startup time, the kernel has already calibrated the TSC (it's needed for the scheduler timer). Use `crate::time::monotonic()` or direct `rdtsc` with the known CPU frequency. If no TSC freq is available yet, use a conservative spin loop calibrated for at least 10ms at minimum CPU speed.
|
||||||
|
|
||||||
|
**Reference**: Intel SDM Vol 3A §8.4.4, Linux `wakeup_secondary_cpu_via_init()`
|
||||||
|
|
||||||
|
#### P16-2: AP Startup ESR Check + Graceful Degradation (Medium K40)
|
||||||
|
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Changes**:
|
||||||
|
1. Before sending INIT IPI: `local_apic.esr()` to clear ESR
|
||||||
|
2. After each SIPI: read ESR to check for delivery errors
|
||||||
|
3. If ESR indicates error after both SIPIs, log warning and skip that CPU
|
||||||
|
4. Track `cpu_online_mask` (AtomicU32 bitmap) separately from `cpu_possible_mask`
|
||||||
|
5. On timeout (trampoline or AP_READY), log which CPU failed and why, continue boot
|
||||||
|
|
||||||
|
**Code structure**: Extract the common AP startup sequence into a helper function to avoid the duplicated code between xAPIC and x2APIC paths.
|
||||||
|
|
||||||
|
#### P16-3: MAX_CPU_COUNT Increase to 256 (High K12)
|
||||||
|
|
||||||
|
**Files**: `src/cpu_set.rs`
|
||||||
|
**Changes**:
|
||||||
|
1. Change `MAX_CPU_COUNT` from 128 to 256 for 64-bit targets
|
||||||
|
2. Add boot-time log: "N CPUs detected, MAX_CPU_COUNT=256"
|
||||||
|
3. Add boot-time warning if CPU count > 200 (approaching limit)
|
||||||
|
|
||||||
|
**Impact**: SET_WORDS grows from 2 to 4 (256/64). LogicalCpuSet becomes 32 bytes instead of 16. All users are by-value or reference, so no ABI break.
|
||||||
|
|
||||||
|
#### P16-4: Firmware Bug Detection (Medium)
|
||||||
|
|
||||||
|
**Files**: `src/acpi/madt/mod.rs`, `src/acpi/mod.rs`
|
||||||
|
**Changes**:
|
||||||
|
1. **Duplicate APIC ID detection**: During MADT iteration in `arch::init()`, collect all APIC IDs in a `BTreeSet<u32>`. If duplicate found, log warning with both entries. Keep first, skip duplicates.
|
||||||
|
2. **SDT checksum validation**: In `acpi/mod.rs`, add `fn validate_sdt_checksum(sdt: &Sdt) -> bool` that sums all bytes and checks == 0. Call for MADT, SRAT, SLIT before use. Log warning and skip table if checksum fails.
|
||||||
|
3. **Unknown MADT type logging**: Already logs via `debug!` but upgrade to `info!` for unknown types. Add MADT revision check.
|
||||||
|
|
||||||
|
#### P16-5: TLB Shootdown Range Race Fix (Critical K3, deferred from P15-3)
|
||||||
|
|
||||||
|
**Files**: `src/percpu.rs`
|
||||||
|
**Changes**: Pack TLB range into a single `AtomicU64`:
|
||||||
|
- Bits [63:32] = start page (up to 2^32 pages = 16TB address space)
|
||||||
|
- Bits [31:0] = count (up to 4 billion pages)
|
||||||
|
- Single `compare_exchange` or `swap` sets the flag + range atomically
|
||||||
|
- Handler unpacks with single `load`
|
||||||
|
- If range is too large for packing, fall back to full shootdown
|
||||||
|
|
||||||
|
**Risk**: Medium. Affects all TLB shootdowns. Must verify no regressions.
|
||||||
|
|
||||||
|
#### P16-6: NUMA Node Before CPU Visible (High K8, deferred from P15-5)
|
||||||
|
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Changes**:
|
||||||
|
1. Move `record_apic_mapping()` and `percpu.numa_node.set()` BEFORE `CPU_COUNT.fetch_add()`
|
||||||
|
2. Add `fence(SeqCst)` between them so scheduler sees NUMA data before the CPU becomes schedulable
|
||||||
|
3. This requires PercpuBlock to be allocated and initialized before the fetch_add — verify that `allocate_and_init_pcr()` and the percpu allocation happen early enough
|
||||||
|
|
||||||
|
**Risk**: Low-Medium. Reordering of operations, must verify AP startup still works.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### Phase 2: Desktop-Safe Scheduler (P17) — ✅ COMPLETE (6 patches)
|
||||||
|
|
||||||
|
#### P17-1: NUMA-Aware Work Stealing (Medium K20) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `src/context/switch.rs`
|
||||||
|
**Patch**: `P17-1-numa-selection.patch`
|
||||||
|
**Change**: In `select_next_context()`, prefer contexts whose last CPU is on the same NUMA node. Two-phase selection: scan for same-node candidates first, fall back to cross-node. New contexts (no last CPU) treated as same-node. Uses `percpu.numa_node` set by P14 SRAT parsing.
|
||||||
|
|
||||||
|
#### P17-2: Transitive Priority Inheritance (Critical K5) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `src/sync/mcs.rs`, `src/percpu.rs`
|
||||||
|
**Patches**: `P17-2a-percpu-waiting.patch`, `P17-2b-transitive-pi.patch`
|
||||||
|
**Change**: Added `waiting_on_lock: AtomicPtr<McsRawLock>` to PercpuBlock. Rewrote `maybe_donate_priority()` to follow the PI chain transitively up to `MAX_PI_CHAIN_DEPTH` (8) hops with cycle detection. Each CPU records which MCS lock it's spinning on before entering the spin loop; the donation function follows `waiting_on_lock → holder_cpu` chains to propagate priority through A→B→C nesting.

#### P17-3: CPU Affinity Syscalls (New Feature) — ✅ DONE (pid=0)
|
||||||
|
|
||||||
|
**Files**: `src/syscall/process.rs`, `src/syscall/mod.rs`
|
||||||
|
**Patches**: `P17-3-sched-affinity.patch`, `P17-3-syscall-dispatch.patch`
|
||||||
|
**Change**: Added `SYS_SCHED_SETAFFINITY` (987) and `SYS_SCHED_GETAFFINITY` (988) as local syscall constants. `sched_affinity: LogicalCpuSet` already existed on Context and was checked in `update_runnable()`. New handlers read/write `RawMask` ([usize; 4], 32 bytes) to/from userspace. Currently supports pid=0 (current process only); PID-based lookup deferred pending lock token architecture work.
|
||||||
|
|
||||||
|
#### P17-4: Configurable Preemption Interval — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `src/context/switch.rs`
|
||||||
|
**Patch**: `P17-4-configurable-preempt.patch`
|
||||||
|
**Change**: Replaced hardcoded `new_ticks >= 3` with per-CPU `preempt_interval: Cell<usize>` on `ContextSwitchPercpu`. Default: `DEFAULT_PREEMPT_INTERVAL = 3` (≈6.75 ms). Infrastructure ready for runtime tuning via syscall or kernel command line.
|
||||||
|
|
||||||
|
#### P17-5: Load Balancing — ✅ MERGED INTO P17-1
|
||||||
|
|
||||||
|
**Note**: The global run queues (shared by all CPUs) make traditional work-stealing unnecessary. The NUMA-aware selection in P17-1 effectively provides the same benefit — idle CPUs naturally pick up cross-node work when same-node work is unavailable.

### Phase 3: Harden Userspace Boot & IPC (P18) — 8/8 complete
|
||||||
|
|
||||||
|
#### P18-1: Daemon Restart Policy (High U4) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `init/src/service.rs`, `scheduler.rs`, `init/src/main.rs`
|
||||||
|
**Patch**: `local/patches/base/P18-1-daemon-restart.patch`
|
||||||
|
**Status**: RestartPolicy enum (Never/OnFailure/Always), max_restarts (default 3), exponential backoff (1s→2s→4s→8s→16s, max 30s). Scheduler tracks supervised PID→ServiceState in BTreeMap. handle_child_exit() in main loop applies restart policy. Built and boot-tested on redbear-mini.
|
||||||
|
|
||||||
|
#### P18-2: Process Monitoring & Cleanup (High U5) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `local/recipes/system/driver-manager/source/src/config.rs`, `main.rs`
|
||||||
|
**Reference Patch**: `local/patches/driver-manager/P18-2-process-monitoring.patch`
|
||||||
|
**Status**: `reap_exited_children()` method on DriverConfig — non-blocking `try_wait()` for all spawned children. `reap_all_drivers()` function polls all configs. Called in deferred retry loop and idle loop (every 5s). Exited drivers are removed from the spawned map and logged.
|
||||||
|
|
||||||
|
#### P18-3: MSI/MSI-X Enablement (High U27) — ✅ DONE (v2)
|
||||||
|
|
||||||
|
**Files**: `drivers/pcid/src/main.rs`
|
||||||
|
**Patch**: `local/patches/base/P18-3-msi-msix-enablement.patch`
|
||||||
|
**Status v2**: In `enable_function()`, MSI/MSI-X capabilities are detected and logged, then disabled to clean state. Legacy IRQ is configured for ALL devices as a baseline (including MSI-capable ones). Drivers that support MSI (e.g., virtio-netd, nvmed) enable MSI themselves via `pci_allocate_interrupt_vector()`. Drivers without MSI support (e.g., ahcid) use the legacy interrupt. Validated on q35 (AHCI MSI device) and i440fx — no panics. Pre-existing virtio-netd MSI allocation bug (irq_helpers.rs:193 .expect() on EEXIST) exposed but not caused by this change.
|
||||||
|
|
||||||
|
#### P18-4: pcid-spawner / driver-manager Unification (High U29)
|
||||||
|
|
||||||
|
**Files**: `local/recipes/system/driver-manager/`, `recipes/core/base/source/drivers/pcid-spawner/`
|
||||||
|
**Change**: Eliminate the race between pcid-spawner and driver-manager by making driver-manager the sole PCI driver spawner. Deprecate pcid-spawner. Driver-manager already has the config infrastructure.
|
||||||
|
|
||||||
|
#### P18-5: ACPID Robustness (High U17) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `drivers/acpid/src/acpi.rs`, `drivers/acpid/src/aml_physmem.rs`
|
||||||
|
**Patch**: `local/patches/base/P18-5-acpid-robustness.patch`
|
||||||
|
**Status**: RSDP_ADDR env var now falls back to BIOS-area probe (0xE0000–0xFFFFF) scanning for "RSD PTR " signature. read_phys_or_fault returns zero instead of panic. map_physical_region maps zero-page fallback on failure. unmap_physical_region logs error instead of expect-panic. Built and boot-tested on redbear-mini.
|
||||||
|
|
||||||
|
#### P18-6: Watchdog/Health Monitoring (High U41)
|
||||||
|
|
||||||
|
**Files**: `recipes/core/base/source/init/src/main.rs`
|
||||||
|
**Change**: Optional health-check ping in scheme protocol. Init checks critical services every 5s. On failure, restart per restart policy.
|
||||||
|
|
||||||
|
#### P18-7: SIGTERM Handling in Daemons (High U39) — ✅ DONE (driver-manager)
|
||||||
|
|
||||||
|
**Files**: `local/recipes/system/driver-manager/source/src/main.rs`, `Cargo.toml`
|
||||||
|
**Reference Patch**: `local/patches/driver-manager/P18-7-sigterm-handler.patch`
|
||||||
|
**Status**: SIGTERM handler via libc::signal setting AtomicBool flag. idle_forever() polls flag every 1s (was 3600s). Deferred retry loop checks flag. graceful_shutdown() function. Added libc dependency. Built and boot-tested on redbear-mini. ACPID shutdown is already handled via kernel kstop pipe.
|
||||||
|
|
||||||
|
#### P18-8: Bounded Scheme Request Queues (Medium) — ✅ COMPLETE
|
||||||
|
|
||||||
|
**Files**: `recipes/core/base/source/ipcd/` (chan.rs, uds/stream.rs, uds/dgram.rs)
|
||||||
|
**Patch**: `local/patches/base/P18-8-bounded-ipcd-queues.patch`
|
||||||
|
**Change**: Added bounded queue depth limits to ipcd: MAX_LISTENER_BACKLOG (64) for channel listeners, MAX_UDS_LISTENER_BACKLOG (64) for UDS stream listeners, MAX_UDS_PACKET_QUEUE (256) for UDS stream packet queues, MAX_DGRAM_QUEUE (256) for UDS datagram queues. Returns ECONNREFUSED when connection backlog is full, EAGAIN when packet/datagram queue is full. Built and boot-tested on redbear-mini.
|
||||||
|
|
||||||
|
#### P18-9: MSI/MSI-X Allocation Resilience (High U27) — ✅ DONE
|
||||||
|
|
||||||
|
**Files**: `drivers/pcid/src/driver_interface/irq_helpers.rs`, `drivers/virtio-core/src/transport.rs`, `drivers/virtio-core/src/arch/x86.rs`, `drivers/net/virtio-netd/src/main.rs`, `drivers/storage/virtio-blkd/src/main.rs`, `drivers/usb/xhcid/src/main.rs`
|
||||||
|
**Patch**: `local/patches/base/P18-9-msi-allocation-resilience.patch`
|
||||||
|
**Status**: Six-file fix for pre-existing MSI vector allocation panic:
|
||||||
|
1. `allocate_aligned_interrupt_vectors()`: Handles `EEXIST` by releasing partial range and restarting search from next aligned position (renamed `first` → `first_aligned` to enable resetting).
|
||||||
|
2. `allocate_single_interrupt_vector_for_msi()`: Returns `Option<(MsiAddrAndData, File)>` instead of panicking. Logs warning on allocation failure.
|
||||||
|
3. `allocate_first_msi_interrupt_on_bsp()`: Returns `Option<File>` instead of panicking.
|
||||||
|
4. `pci_allocate_interrupt_vector()`: Proper MSI-X → MSI → legacy fallback chain. MSI-X is only enabled in config space after successful vector allocation. On failure, falls back without leaving MSI-X enabled.
|
||||||
|
5. `virtio-core/transport.rs`: Added `MsiAllocationFailed` error variant.
|
||||||
|
6. `virtio-core/arch/x86.rs`: Uses `ok_or(Error::MsiAllocationFailed)?` instead of panicking.
|
||||||
|
7. `virtio-netd/main.rs` and `virtio-blkd/main.rs`: `daemon_runner` logs error and exits cleanly instead of `.unwrap()` panic.
|
||||||
|
8. `xhcid/main.rs`: MSI-X → MSI → legacy → polling fallback chain.
|
||||||
|
**Validated**: Boots on q35/4CPU with zero panics. virtio-netd exits gracefully when no vectors available. ahcid uses legacy IRQ. Rest of system continues normally.
|
||||||
|
|

### Phase 4: Stress Test & Validation (P19) — 2/4 complete
|
||||||
|
|
||||||
|
#### P19-1: Multi-Core Driver Stress Test — ✅ PASS (2026-05-17)
|
||||||
|
|
||||||
|
**Result**: QEMU q35 machine with 4 CPUs booted to login successfully. AHCI, virtio-blk, and all core drivers started without panics.
|
||||||
|
**Script**: `local/scripts/test-smp-stress-qemu.sh`
|
||||||
|
|
||||||
|
**Findings**:
|
||||||
|
- ✅ 4 CPUs online, SMP scheduler stable
|
||||||
|
- ✅ AHCI driver started (IRQ 10 legacy fallback) — P18-3 v2 fix validated
|
||||||
|
- ✅ virtio-blk disk detected (3M sectors)
|
||||||
|
- ✅ ACPID, pcid, ipcd all stable
|
||||||
|
- ✅ virtio-netd exits gracefully instead of panicking — P18-9 fix (was: irq_helpers.rs:193 .expect() on EEXIST)
|
||||||
|
- ✅ driver-manager probe loop bounded by P18-2 max_retries=3 (reduced from 30)
|
||||||
|
- ❌ dd-based I/O stress ineffective — Redox `/dev/null` is a scheme, shell redirection fails
|
||||||
|
- **Remaining**: (1) Root cause why CPU 0 has no available MSI vectors on q35 (kernel vector count investigation), (2) Redesign stress test for Redox scheme-based I/O
|
||||||
|
|
||||||
|
#### P19-2: IRQ Vector Debug + Close Bug Fix — ✅ DONE (2026-05-17)
|
||||||
|
|
||||||
|
**Patch**: `local/patches/kernel/P19-2-irq-debug.patch`
|
||||||
|
|
||||||
|
**Changes** (kernel `scheme/irq.rs` + `arch/x86_shared/idt.rs`):
|
||||||
|
1. **Bug fix**: `Handle::Irq` now stores `cpu_id: LogicalCpuId` alongside `irq` and `ack`. Previously, `close()` always unreserved on BSP (`LogicalCpuId::BSP`) regardless of which CPU the vector was allocated on — a correctness bug causing vector leaks on APs.
|
||||||
|
2. **Debug logging**: `available_irqs_iter()` logs `cpu_id` and available vector count per call.
|
||||||
|
3. **Debug logging**: IRQ `getdents` for `Handle::Avail` logs `cpu_id`, `opaque`, and number of entries listed.
|
||||||
|
4. **Debug logging**: IRQ `close()` logs which CPU the vector is being unreserved on.
|
||||||
|
|
||||||
|
**Purpose**: Runtime diagnosis of the IRQ vector scarcity mystery on q35 (CPU 0 appearing to have zero available MSI vectors despite ~201 expected). The debug logs will reveal whether the IDT reservations are correct at runtime and whether `read_dir` is returning empty or if the issue is elsewhere.
|
||||||
|
|
||||||
|
**Note**: This is a diagnostic patch. Once the IRQ vector scarcity root cause is confirmed and fixed, the `log::info!` calls should be removed or converted to `log::debug!`.
|
||||||
|
|
||||||
|
#### P19-2b: Repo Cook Fork Safety Hardening — ✅ DONE (2026-05-17)
|
||||||
|
|
||||||
|
**Changes** (build system `src/cook/fetch.rs` + `cookbook.toml`):
|
||||||
|
1. **`cookbook.toml`**: Created with explicit `offline = true` — makes the offline-first policy explicit rather than relying on code defaults.
|
||||||
|
2. **Auto-protect patched recipes**: `recipe_has_patches()` function checks if a recipe has patches in its `recipe.toml`. `redbear_should_protect()` now protects any recipe that either (a) is on the explicit protected list, OR (b) has patches. This prevents accidental upstream re-fetching from breaking patch context lines.
|
||||||
|
3. **Warning on bypass**: When `--allow-protected` is used on a patched recipe, a `[WARN]` message is logged: "recipe X has patches but --allow-protected is set — upstream source changes may break patches".
|
||||||
|
|
||||||
|
**Audit result**: The 3-layer protection (COOKBOOK_OFFLINE=true → fetch_offline, redbear_protected_recipe → redirect to fetch_offline, REDBEAR_RELEASE → block explicit fetch) is solid. The auto-protect addition closes the gap where a recipe with patches but not on the explicit list could be re-fetched from upstream.

## Firmware Loading Assessment (Added 2026-05-16)
|
||||||
|
|
||||||
|
### Architecture
|
||||||
|
|
||||||
|
The firmware loading system is well-designed with three-tier caching:
|
||||||
|
1. **In-memory cache** (`HashMap<String, CachedBlob>`)
|
||||||
|
2. **Persistent cache** (`/var/lib/firmware/cache`) — survives daemon restarts
|
||||||
|
3. **Filesystem** (`/lib/firmware`) — primary source
|
||||||
|
|
||||||
|
**Fallback chains**: TOML-configured in `/etc/firmware-fallbacks.d/`, with built-in fallbacks for AMD DCN and Intel Wi-Fi.
|
||||||
|
|
||||||
|
**Linux KPI compatibility**: `request_firmware()` / `release_firmware()` via `linux-kpi/source/src/rust_impl/firmware.rs`.
|
||||||
|
|
||||||
|
### Firmware Issues
|
||||||
|
|
||||||
|
| # | Severity | Issue | File | Detail |
|
||||||
|
|---|----------|-------|------|--------|
|
||||||
|
| FW1 | Critical | No real AMD GPU firmware files | `local/firmware/` (empty) | DCN 3.5+, GC 11.x, PSP, SDMA, VCN firmware missing |
|
||||||
|
| FW2 | Critical | No real Intel Wi-Fi firmware files | `local/firmware/` (empty) | AX200/AX201/AX210/AX211 .ucode files missing |
|
||||||
|
| FW3 | Critical | Driver vs firmware-loader race | `driver-manager/config.rs:236` | Only checks scheme path, not specific files |
|
||||||
|
| FW4 | Critical | No firmware-ready notifications | `firmware-loader/async.rs` | Uevents dispatched but no consumers |
|
||||||
|
| FW5 | Critical | No firmware dependency in driver config | `driver-manager/config.rs:532` | Drivers can't declare required firmware files |
|
||||||
|
| FW6 | High | No boot-critical firmware pre-population | initfs | Display firmware not embedded for early boot |
|
||||||
|
| FW7 | High | Deferred probe timeout too short | `driver-manager/main.rs:407` | 15s total (500ms × 30 retries) insufficient for large GPU firmware |
|
||||||
|
| FW8 | High | No firmware loader crash recovery | init | If firmware-loader crashes, /scheme/firmware gone permanently |
|
||||||
|
| FW9 | High | No firmware version pinning | `manifest.rs` | SHA256 hashes generated but never validated on load |
|
||||||
|
| FW10 | Medium | Cache poisoning on concurrent access | `blob.rs:645` | Mutex poisoned on panic, subsequent cache accesses fail silently |
|
||||||
|
| FW11 | Medium | No per-operation firmware load timeout | `scheme.rs:16` | Single 5s timeout for all firmware regardless of size |
|
||||||
|
| FW12 | Medium | No firmware inventory tool | `main.rs` | No `/proc/firmware` equivalent for debugging |
|
||||||
|
| FW13 | Medium | No firmware size limits | `linux-kpi/firmware.rs:65` | Arbitrary-size allocation, potential DoS |
|
||||||
|
| FW14 | Low | No firmware signature verification | all | SHA256 hashes not validated on load |
|
||||||
|
|
||||||
|
### Firmware Loading Patches (P18-FW Series)
|
||||||
|
|
||||||
|
#### P18-FW1: Firmware Availability Handshake (Critical FW3, FW5)
|
||||||
|
**Files**: `local/recipes/system/firmware-loader/source/src/scheme.rs`, `local/recipes/system/driver-manager/source/src/config.rs`
|
||||||
|
**Change**:
|
||||||
|
1. firmware-loader publishes indexed firmware list at `/scheme/firmware/.index`
|
||||||
|
2. driver-manager checks specific firmware files before probing driver
|
||||||
|
3. Add `firmware_requires = [...]` to driver config TOML schema
|
||||||
|
|
||||||
|
#### P18-FW2: Firmware Loader Watchdog + Restart (High FW8)
|
||||||
|
**Files**: `recipes/core/base/source/init/src/service.rs`
|
||||||
|
**Change**: Add `restart = "always"` to firmware-loader service. Init respawns on crash.
|
||||||
|
|
||||||
|
#### P18-FW3: Extended Deferred Probe Timeout (High FW7)
|
||||||
|
**Files**: `local/recipes/system/driver-manager/source/src/main.rs`

||||||
|
**Change**: Increase max_retries to 60 (30s total), add per-driver `probe_timeout` config.
|
||||||
|
|
||||||
|
#### P18-FW4: Firmware Pre-Population for Boot-Critical Devices (High FW6)
|
||||||
|
**Files**: `config/redbear-full.toml`

## 1. Executive Summary
|
|
||||||
|
|
||||||
Red Bear OS is **architecturally sound** but has **significant gaps in hardware-facing
|
|
||||||
subsystems**. The system boots to a login prompt in QEMU with working console,
|
|
||||||
networking, and basic device enumeration. However, the boot log and codebase audit
|
|
||||||
reveal that **bare-metal usability is limited**: the system runs hot (no C-states,
|
|
||||||
no thermal backend), may not see all CPU cores (AP startup races), may lose USB
|
|
||||||
keyboard (only xHCI exists), and has minimal observability for operators.
|
|
||||||
|
|
||||||
This document is a **truthful, evidence-based assessment** of every low-level
|
|
||||||
subsystem, grounded in source code inspection, boot log analysis, and comparison
|
|
||||||
against Linux 7.1 reference source. It replaces five stale/duplicate planning
|
|
||||||
documents with one canonical assessment and forward plan.
|
|
||||||
|
|
||||||
### Bottom-line verdicts
|
|
||||||
|
|
||||||
| Subsystem | Verdict |
|
|
||||||
|-----------|---------|
|
|
||||||
| **SMP** | Real in kernel, but AP startup races and no bare-metal validation |
|
|
||||||
| **CPU power (C-states)** | **Completely missing** — root cause of heat on bare metal |
|
|
||||||
| **CPU power (P-states)** | Partial — cpufreqd exists but fragile |
|
|
||||||
| **Thermal / sensors** | Daemon exists but **no backend** — runs with empty surface |
|
|
||||||
| **ACPI boot** | Boot-baseline complete, not release-grade |
|
|
||||||
| **ACPI thermal/fan** | **Missing** — not implemented in acpid |
|
|
||||||
| **USB xHCI** | Real, QEMU-validated only |
|
|
||||||
| **USB EHCI/UHCI/OHCI** | **No drivers exist** — bare-metal USB keyboard unreliable |
|
|
||||||
| **PCI / IRQ / MSI-X** | Architecturally strong, low adoption in drivers |
|
|
||||||
| **IOMMU AMD-Vi** | Real, QEMU first-use proof only |
|
|
||||||
| **IOMMU Intel VT-d** | **Missing** — orphaned DMAR parsing only |
|
|
||||||
| **Firmware loading** | Real, on-demand, async |
|
|
||||||
| **Memory management** | Basic frame allocator — no swap/NUMA/hotplug |
|
|
||||||
| **Logging** | Append-only `/var/log/system.log` — no rotation/structured storage |
|
|
||||||
| **Udev** | Real but limited — polling hotplug, hardcoded rules |
|
|
||||||

## 2. Assessment by Subsystem
|
|
||||||
|
|
||||||
### 2.1 SMP / CPU Bring-up
|
|
||||||
|
|
||||||
**Status**: 🟡 Implemented, QEMU-proven, **bare-metal unvalidated**
|
|
||||||
**Linux 7.1 equivalent**: `arch/x86/kernel/smpboot.c`, `arch/x86/kernel/apic/`,
|
|
||||||
`kernel/smp.c`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
The kernel has a **complete AP bring-up path**:
|
|
||||||
|
|
||||||
- AP trampoline with INIT/SIPI sequencing (`madt/arch/x86.rs`)
|
|
||||||
- x2APIC/LocalApic branching with zero-extended ID fallback
|
|
||||||
(`local_apic.rs`)
|
|
||||||
- `multi_core` feature enabled by default (`Cargo.toml`)
|
|
||||||
- Per-CPU data structures (`percpu.rs`)
|
|
||||||
- IPI support for TLB shootdowns and scheduler wakeups
|
|
||||||
- CPU set tracking (`cpu_set.rs`)
|
|
||||||
|
|
||||||
Source files inspected:
|
|
||||||
- `recipes/core/kernel/source/src/acpi/madt/arch/x86.rs`
|
|
||||||
- `recipes/core/kernel/source/src/arch/x86_shared/device/local_apic.rs`
|
|
||||||
- `recipes/core/kernel/source/src/startup/mod.rs`
|
|
||||||
- `recipes/core/kernel/source/src/cpu_set.rs`
|
|
||||||
|
|
||||||
#### Why you see "SMP: 1 CPUs online"
|
|
||||||
|
|
||||||
The boot log shows:
|
|
||||||
|
|
||||||
```
|
|
||||||
kernel::acpi::madt::arch:INFO -- SMP: 1 CPUs online (max 256)
|
|
||||||
```
|
|
||||||
|
|
||||||
This can happen for three reasons:
|
|
||||||
|
|
||||||
1. **QEMU i440fx exposes only 1 vCPU to the guest** (most likely in this boot)
|
|
||||||
2. **AP startup timeout** — `AP_SPIN_LIMIT=1_000_000` spin counts vary by clock
|
|
||||||
speed; on slow or heavily loaded bare metal, APs may not signal readiness in
|
|
||||||
time
|
|
||||||
3. **Firmware MADT only exposes 1 processor entry** — rare but possible on
|
|
||||||
broken firmware
|
|
||||||
|
|
||||||
On real bare metal with an AMD Ryzen or Intel Core system, if the firmware
|
|
||||||
exposes multiple LocalApic entries and AP startup succeeds, the kernel **will**
|
|
||||||
bring up all cores. But this has **never been validated** on the project's
|
|
||||||
hardware matrix.
|
|
||||||
|
|
||||||
#### Critical weaknesses (38 kernel issues found)
|
|
||||||
|
|
||||||
`SMP-BOOT-HARDENING-PLAN.md` (2026-05-16) documented **54 issues** across kernel
|
|
||||||
and userspace boot. The most critical kernel-side items are:
|
|
||||||
|
|
||||||
| Issue | Severity | File | Description |
|
|
||||||
|-------|----------|------|-------------|
|
|
||||||
| AP startup LogicalCpuId race | **Critical** | `madt/arch/x86.rs:153,244,276,365` | Two APs load `CPU_COUNT` simultaneously → same ID |
|
|
||||||
| AP_READY dual-mechanism race | **Critical** | `madt/arch/x86.rs:174-225` | Trampoline u64 write + static `AtomicBool` — inconsistent ordering |
|
|
||||||
| TLB shootdown range race | **Critical** | `percpu.rs:134-137` | Concurrent shootdowns overwrite range between flag set and IPI |
|
|
||||||
| MCS lock missing fences | **Critical** | `sync/mcs.rs:74-101` | No Release/Acquire on MCS lock handoff |
|
|
||||||
| Unbounded priority inversion | **Critical** | `sync/mcs.rs:126-145` | PI donation one level only |
|
|
||||||
| Scheduler panic flag leak | **Critical** | `switch.rs:164,298` | `in_context_switch` stays true on panic → CPU lockup |
|
|
||||||
| Missing SIPI delays | **High** | `madt/arch/x86.rs:192-337` | Spin-count delays, not TSC-based. Intel SDM requires 10ms INIT→SIPI |
|
|
||||||
| NUMA node set after CPU visible | **High** | `madt/arch/x86.rs:244,253` | `CPU_COUNT.fetch_add()` before `numa_node.set()` |
|
|
||||||
| MAX_CPU_COUNT=128 too small | **High** | `cpu_set.rs:44` | AMD EPYC has 128C/256T, Threadripper PRO 96C/192T |
|
|
||||||
| Global IRQ count lock | **High** | `scheme/irq.rs:67` | `COUNTS.lock()` is global spinlock on hot path |
|
|
||||||
|
|
||||||
These are **not theoretical**. The LogicalCpuId race means two APs can claim
|
|
||||||
the same CPU ID, leading to corrupted per-CPU data. The missing SIPI delays
|
|
||||||
mean APs may fail to start on real hardware with strict firmware timing
|
|
||||||
requirements.
|
|
||||||
|
|
||||||
#### Gaps vs Linux 7.1
|
|
||||||
|
|
||||||
| Feature | Linux 7.1 | Red Bear |
|
|
||||||
|---------|-----------|----------|
|
|
||||||
| Robust AP bring-up | `smpboot.c` with TSC delays, online checks | Spin-count delays, race conditions |
|
|
||||||
| CPU hotplug | Full hot-add/hot-remove | Not implemented |
|
|
||||||
| CPU isolation | `isolcpus`, `nohz_full` | Not implemented |
|
|
||||||
| NUMA | Node-aware scheduling, memory policies | No NUMA awareness |
|
|
||||||
| Per-CPU idle threads | `cpuhp/`, idle thread per CPU | APs enter idle loop directly |
|
|
||||||
| x2APIC fallback | Clean fallback with explicit disable | Fallback works but warns |
|
|
||||||
|
|
||||||
**Verdict**: SMP infrastructure is real but has **critical races** that must be
|
|
||||||
fixed before bare-metal multi-core can be trusted. No hardware validation exists.

### 2.2 CPU Power Management (P-states / C-states)
|
|
||||||
|
|
||||||
**Status**: 🟡 P-states partial, **C-states missing entirely**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/cpufreq/`, `drivers/cpuidle/`,
|
|
||||||
`drivers/acpi/processor.c`, `arch/x86/kernel/acpi/cstate.c`
|
|
||||||
|
|
||||||
#### P-states (frequency scaling)
|
|
||||||
|
|
||||||
`cpufreqd` is a **real userspace daemon** that:
|
|
||||||
|
|
||||||
- Reads ACPI `_PSS` (Performance States) tables
|
|
||||||
- Samples CPU load periodically
|
|
||||||
- Writes `IA32_PERF_CTL` MSR to change P-state
|
|
||||||
- Supports governors: Ondemand, Performance, Powersave
|
|
||||||
- Exposes `/scheme/cpufreq`
|
|
||||||
|
|
||||||
Source: `local/recipes/system/cpufreqd/source/src/main.rs`
|
|
||||||
|
|
||||||
**But it is fragile**:
|
|
||||||
|
|
||||||
1. `write_msr()` ignores its `msr` parameter and writes only the value to
|
|
||||||
`/dev/cpu/<n>/msr`. This suggests it depends on a Linux-style MSR driver that
|
|
||||||
uses file offset as the MSR index. No such driver was found in the Red Bear
|
|
||||||
tree.
|
|
||||||
2. The daemon reads MSR temperature via `IA32_THERM_STATUS` but has no
|
|
||||||
actionable thermal policy — it can request "powersave" from cpufreqd itself,
|
|
||||||
but there is no thermal trip point logic.
|
|
||||||
3. On the boot log: `cpufreqd: CPU0: 4 P-states (2400 - 1200 kHz)` followed by
|
|
||||||
`cpufreqd: CPU0: MSR write failed (1/1)` — **the P-state change is failing**.
|
|
||||||
|
|
||||||
#### C-states (idle power states)
|
|
||||||
|
|
||||||
**This is completely missing** and is the **single largest contributor to system
|
|
||||||
heat on bare metal**.
|
|
||||||
|
|
||||||
What exists:
|
|
||||||
- The kernel has a normal `hlt` instruction in the idle loop when no threads are
|
|
||||||
runnable
|
|
||||||
- No dedicated cpuidle subsystem
|
|
||||||
- No ACPI `_CST` (C-state) table parsing
|
|
||||||
- No `mwait` / `monitor` usage for deeper C-states
|
|
||||||
- No C1E, C3, C6, C7 support
|
|
||||||
|
|
||||||
What Linux 7.1 has:
|
|
||||||
- `drivers/cpuidle/` with multiple drivers: `acpi_idle`, `intel_idle`, `amd_idle`
|
|
||||||
- `_CST` table parsing in ACPI processor driver
|
|
||||||
- `mwait` hint selection based on C-state depth
|
|
||||||
- Latency and power measurements per C-state
|
|
||||||
- Scheduler integration: `cpuidle_enter()` called from idle loop
|
|
||||||
|
|
||||||
**Verdict**: cpufreqd is real but MSR writes are failing. C-states are
|
|
||||||
**completely absent**. On bare metal, CPUs run at full power even when idle.
|
|
||||||
This is why the system is "very hot."
|
|
||||||

|
||||||
### 2.3 Thermal Management / Sensors / Hardware Monitoring
|
|
||||||
|
|
||||||
**Status**: 🔴 Thermal daemon exists but **no backend**; sensors missing; hwmon
|
|
||||||
absent
|
|
||||||
**Linux 7.1 equivalent**: `drivers/thermal/`, `drivers/hwmon/`,
|
|
||||||
`drivers/acpi/thermal.c`, `drivers/acpi/fan.c`
|
|
||||||
|
|
||||||
#### thermald
|
|
||||||
|
|
||||||
`thermald` is **real code**, not a stub. It:
|
|
||||||
|
|
||||||
- Attempts to read ACPI thermal zones
|
|
||||||
- Reads CPU MSR temperature (`IA32_THERM_STATUS`)
|
|
||||||
- Can request powersave from cpufreqd
|
|
||||||
- Can request ACPI sleep
|
|
||||||
- Exposes `/scheme/thermal`
|
|
||||||
|
|
||||||
Source: `local/recipes/system/thermald/source/src/main.rs`
|
|
||||||
|
|
||||||
**But it runs with an empty surface**:
|
|
||||||
|
|
||||||
- ACPI thermal zone enumeration is **missing from acpid**. The ACPI daemon's
|
|
||||||
scheme surface (`/scheme/acpi`) has no thermal or fan nodes.
|
|
||||||
- `thermald` expects `/scheme/acpi/thermal` and `/scheme/acpi/fan` to exist, but
|
|
||||||
they do not.
|
|
||||||
- `fan.rs` exists in the thermald source tree but is **orphaned** — it is not
|
|
||||||
wired into `main.rs` (`mod fan;` is absent).
|
|
||||||
|
|
||||||
The boot log shows:
|
|
||||||
|
|
||||||
```
|
|
||||||
[ OK ] Started Thermal management daemon
|
|
||||||
2026-05-20T09-13-44.583Z [@thermald:19 INFO] thermald: started
|
|
||||||
```
|
|
||||||
|
|
||||||
And then nothing. No thermal zones found, no temperature readings, no fan
|
|
||||||
control.
|
|
||||||
|
|
||||||
#### Hardware sensors (hwmon)
|
|
||||||
|
|
||||||
**There is no hwmon infrastructure** in Red Bear OS.
|
|
||||||
|
|
||||||
What is missing:
|
|
||||||
- No `/sys/class/hwmon` equivalent
|
|
||||||
- No `/scheme/hwmon`
|
|
||||||
- No sensor drivers
|
|
||||||
|
|
||||||
Linux 7.1 has **100+ hwmon drivers** covering:
|
|
||||||
- CPU temperature: `coretemp` (Intel), `k10temp` (AMD)
|
|
||||||
- Motherboard sensors: `nct6775`, `it87`, `f71882fg`
|
|
||||||
- Voltage regulators: `ina2xx`, `ltc2947`
|
|
||||||
- Fan speed monitors: various Super-I/O chips
|
|
||||||
|
|
||||||
Red Bear has **none of these**.
|
|
||||||
|
|
||||||
#### SMBIOS / DMI
|
|
||||||
|
|
||||||
SMBIOS parsing exists in `acpid/src/dmi.rs`, but the boot log shows:
|
|
||||||
|
|
||||||
```
|
|
||||||
2026-05-20T09-12-40.920Z [@acpid::dmi:124 WARN] SMBIOS entry point not found in 0xF0000-0xFFFFF
|
|
||||||
```
|
|
||||||
|
|
||||||
This means DMI-based quirks and system identification are **best-effort only**.
|
|
||||||
On systems without a valid SMBIOS entry point, the quirk system falls back to
|
|
||||||
PCI/USB device ID matching only.
|
|
||||||
|
|
||||||
**Verdict**: thermald is real but powerless. No hwmon, no sensor drivers, no
|
|
||||||
ACPI thermal backend. The system has **zero thermal awareness**.
|
|
||||||

### 2.4 ACPI Stack
|
|
||||||
|
|
||||||
**Status**: 🟡 Boot-baseline complete, **not release-grade**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/acpi/`, `include/acpi/`
|
|
||||||
|
|
||||||
#### What is strong
|
|
||||||
|
|
||||||
- Kernel early ACPI discovery: RSDP, RSDT, XSDT
|
|
||||||
- MADT parsing: LocalApic, IoApic, IntSrcOverride, NMI
|
|
||||||
- x2APIC fallback with zero-extended IDs
|
|
||||||
- FADT parsing, PM1a/PM1b register access
|
|
||||||
- AML interpreter v6.1.1 with real mutex tracking
|
|
||||||
- EC (Embedded Controller) byte-transaction access
|
|
||||||
- `_S5` shutdown derivation (though timing is fragile)
|
|
||||||
- `kstop` kernel shutdown eventing consumed by `redbear-sessiond`
|
|
||||||
- DMI exposure via `/scheme/acpi/dmi`
|
|
||||||
|
|
||||||
Source files:
|
|
||||||
- `recipes/core/kernel/source/src/acpi/`
|
|
||||||
- `recipes/core/base/source/drivers/acpid/src/`
|
|
||||||
|
|
||||||
#### What is weak
|
|
||||||
|
|
||||||
| Area | Status | Detail |
|
|
||||||
|------|--------|--------|
|
|
||||||
| acpid startup | Fragile | Active panic-grade `expect()` paths on firmware-origin data |
|
|
||||||
| `_S5` timing | Fragile | Derived after PCI registration; pre-PCI shutdown reports "AML not ready" |
|
|
||||||
| DMAR | Orphaned | Parsing exists in `acpid/src/dmar/mod.rs` but not wired; Intel VT-d has no owner |
|
|
||||||
| Sleep beyond S5 | Missing | `set_global_s_state()` is S5-only; S3 suspend not validated |
|
|
||||||
| Thermal zones | Missing | No ACPI thermal zone enumeration |
|
|
||||||
| Fan devices | Missing | No ACPI fan device support |
|
|
||||||
| Battery/power | Provisional | `power_snapshot()` does real AML-backed probing but bootstrap preconditions are weak |
|
|
||||||
| AML fault handling | Partial | `aml_physmem.rs` has "log then fabricate 0" paths |
|
|
||||||
| SMBIOS | Best-effort | Entry point missing on many systems |
|
|
||||||
|
|
||||||
The ACPI improvement plan (`ACPI-IMPROVEMENT-PLAN.md`) tracks 8 waves of work
|
|
||||||
(W0–W7). Current status:
|
|
||||||
- W0 (Contracts): partially complete
|
|
||||||
- W1 (Startup hardening): partially complete
|
|
||||||
- W2 (AML ordering/shutdown): partially complete
|
|
||||||
- W3 (Honest power surface): **open**
|
|
||||||
- W4 (Physmem/EC/fault): partially complete
|
|
||||||
- W5 (Ownership cleanup): **open**
|
|
||||||
- W6 (Consumer integration): partially complete
|
|
||||||
- W7 (Validation closure): **open**
|
|
||||||
|
|
||||||
**Verdict**: ACPI is the most mature low-level subsystem, but it is still
|
|
||||||
**boot-baseline complete**, not release-grade. Thermal and fan support are
|
|
||||||
completely absent.

|

### 2.5 PCI / IRQ / MSI-X
|
|
||||||
|
|
||||||
**Status**: 🟡 Architecturally strong, **adoption-incomplete**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/pci/`, `arch/x86/kernel/apic/`,
|
|
||||||
`drivers/iommu/`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
- `pcid` enumerates PCI devices via config space (I/O ports 0xCF8/0xCFC fallback
|
|
||||||
when no ECAM/MCFG)
|
|
||||||
- Capability parsing: MSI, MSI-X, power management, vendor-specific
|
|
||||||
- `driver-manager` matches TOML configs by bus/class/vendor and spawns drivers
|
|
||||||
- Kernel MSI message composition and validation (`msi.rs`, `vector.rs`)
|
|
||||||
- MSI-X table mapping and vector allocation
|
|
||||||
- `redox-driver-sys` provides IRQ handle abstractions, affinity helpers
|
|
||||||
- IOAPIC routing with interrupt source overrides
|
|
||||||
- Legacy PIC fallback
|
|
||||||
|
|
||||||
Source files:
|
|
||||||

|
|
||||||
- `local/recipes/system/driver-manager/`
|
|
||||||
- `recipes/core/kernel/source/src/arch/x86_shared/device/msi.rs`
|
|
||||||
- `local/recipes/drivers/redox-driver-sys/source/src/irq.rs`
|
|
||||||
|
|
||||||
#### What is weak
|
|
||||||
|
|
||||||
| Issue | Detail |
|
|
||||||
|-------|--------|
|
|
||||||
| Legacy IRQ dominance | `e1000d` and `ided` still use legacy IRQ (IRQ 11, IRQ 14/15) |
|
|
||||||
| MSI-X adoption | Only `ixgbed` and GPU paths use MSI-X; most drivers on legacy INTx |
|
|
||||||
| IOMMU MSI gate | `iommu_validate_msi_irq()` is a stub — always returns `true` |
|
|
||||||
| IRQ affinity | Available in API but not widely used |
|
|
||||||
| pcid helper fragility | Some paths still treat malformed capabilities as invariants |
|
|
||||||
| Hardware validation | MSI-X proven in QEMU only; no real hardware vector validation |
|
|
||||||
|
|
||||||
The IRQ/low-level plan (`IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md`)
|
|
||||||
correctly identifies that the architecture is sound but the **runtime proof is
|
|
||||||
thin**. Priority 1 is "MSI-X runtime validation on real devices."
|
|
||||||
|
|
||||||
**Verdict**: The PCI/IRQ substrate is one of the strongest parts of the stack,
|
|
||||||
but it is **not yet release-grade** because MSI-X is not widely adopted and
|
|
||||||
hardware validation is missing.

### 2.6 IOMMU / DMA
|
|
||||||
|
|
||||||
**Status**: 🟡 AMD-Vi real but **unvalidated**; Intel VT-d **missing**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/iommu/amd/`, `drivers/iommu/intel/`,
|
|
||||||
`drivers/iommu/dma-iommu.c`
|
|
||||||
|
|
||||||
#### AMD-Vi
|
|
||||||
|
|
||||||
The `iommu` daemon is **real**, not a stub:
|
|
||||||
|
|
||||||
- `AmdViUnit::init()` maps MMIO, programs device tables, command buffer, event
|
|
||||||
log, interrupt remap table (IRTE)
|
|
||||||
- QEMU first-use proof passes: discovers units, initializes, drains events
|
|
||||||
- Self-test path exists: `redbear-phase-iommu-check`
|
|
||||||
|
|
||||||
Source: `local/recipes/system/iommu/source/src/amd_vi.rs`
|
|
||||||
|
|
||||||
**But**:
|
|
||||||
- The boot log shows: `iommu: no AMD-Vi units found (source=none,
|
|
||||||
kernel_acpi_status=empty, ivrs_path=none)`
|
|
||||||
- This happens because the IVRS table is absent on this platform (QEMU i440fx
|
|
||||||
does not provide IVRS)
|
|
||||||
- When zero units are found, the daemon registers `scheme:iommu` and exits
|
|
||||||
- **Real AMD hardware validation: NONE**
|
|
||||||
|
|
||||||
#### Intel VT-d
|
|
||||||
|
|
||||||
- DMAR parsing exists in `acpid/src/dmar/mod.rs` but is **orphaned**
|
|
||||||
- No Intel VT-d runtime daemon
|
|
||||||
- No DMA remapping for Intel platforms
|
|
||||||
- `iommu` daemon is AMD-Vi only
|
|
||||||
|
|
||||||
#### DMA integration
|
|
||||||
|
|
||||||
- DMA allocation exists in `redox-driver-sys`
|
|
||||||
- But IOMMU integration is incomplete: `iommu_validate_msi_irq()` is a no-op,
|
|
||||||
and there is no enforced DMA map/unmap with IOMMU translation
|
|
||||||
- Linux 7.1 has `dma-iommu.c` which handles IOMMU-aware DMA mapping for all
|
|
||||||
devices behind an IOMMU
|
|
||||||
|
|
||||||
**Verdict**: AMD-Vi is implemented but unvalidated. Intel VT-d is missing.
|
|
||||||
DMA/IOMMU integration is incomplete.

### 2.7 USB Stack
|
|
||||||
|
|
||||||
**Status**: 🟡 xHCI real but **QEMU-only**; **EHCI/UHCI/OHCI missing**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/usb/host/`, `drivers/usb/core/`,
|
|
||||||
`drivers/hid/usbhid/`
|
|
||||||
|
|
||||||
#### xHCI
|
|
||||||
|
|
||||||
The xHCI driver (`xhcid`) is **real and substantial**:
|
|
||||||
|
|
||||||
- ~6,000 lines of Rust
|
|
||||||
- 88+ error handling fixes applied via Red Bear patch
|
|
||||||
- Interrupt-driven path restored (MSI/MSI-X/INTx)
|
|
||||||
- Event ring growth implemented (ring doubling)
|
|
||||||
- BOS/SuperSpeed descriptor fetching
|
|
||||||
- Speed detection for hub children
|
|
||||||
- USB 3 hub endpoint configuration
|
|
||||||
- Suspend/resume API skeleton
|
|
||||||
|
|
||||||
Source: `recipes/core/base/source/drivers/usb/xhcid/`
|
|
||||||
|
|
||||||
**But**:
|
|
||||||
- Only **QEMU-validated** — no real hardware testing
|
|
||||||
- ~57 TODO/FIXME comments remain
|
|
||||||
- Some `panic!()` sites remain in device enumerator
|
|
||||||
|
|
||||||
#### Missing host controllers
|
|
||||||
|
|
||||||
**No EHCI, UHCI, or OHCI drivers exist** in the Red Bear tree.
|
|
||||||
|
|
||||||
| Controller | Speed | Why it matters |
|
|
||||||
|------------|-------|----------------|
|
|
||||||
| EHCI | USB 2.0 High Speed | Most USB 2.0 keyboards/mice |
|
|
||||||
| OHCI | USB 1.1 Full/Low Speed | AMD/VIA legacy USB |
|
|
||||||
| UHCI | USB 1.1 Full/Low Speed | Intel legacy USB |
|
|
||||||
|
|
||||||
Linux 7.1 has full implementations for all three:
|
|
||||||
- `drivers/usb/host/ehci-hcd.c` (~4,500 lines)
|
|
||||||
- `drivers/usb/host/ohci-hcd.c` (~3,500 lines)
|
|
||||||
- `drivers/usb/host/uhci-hcd.c` (~2,800 lines)
|
|
||||||
|
|
||||||
The USB implementation plan honestly states:
|
|
||||||
|
|
||||||
> "External USB keyboard input is reliably available only when the keyboard is
|
|
||||||
> reached through the `xHCI -> usbhubd/usbhidd -> inputd` path."
|
|
||||||
|
|
||||||
On many bare-metal systems, USB keyboards route through EHCI or OHCI, not xHCI.
|
|
||||||
**Red Bear cannot claim reliable USB keyboard boot fallback.**
|
|
||||||
|
|
||||||
#### Class drivers
|
|
||||||
|
|
||||||
| Driver | Status | Quality |
|
|
||||||
|--------|--------|---------|
|
|
||||||
| `usbhubd` | Real | Good — interrupt-driven change detection, graceful per-port errors |
|
|
||||||
| `usbhidd` | Real | Good — HID report parsing, named producers, no panics in loop |
|
|
||||||
| `usbscsid` | Real | Good — BOT transport, stall recovery, `ReadCapacity16` |
|
|
||||||
|
|
||||||
**Verdict**: xHCI is real but QEMU-only. The absence of EHCI/UHCI/OHCI is a
|
|
||||||
**critical bare-metal gap**.

### 2.8 Firmware Loading
|
|
||||||
|
|
||||||
**Status**: 🟢 **Real and functional**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/base/firmware_loader/`
|
|
||||||
|
|
||||||
The `firmware-loader` daemon is one of the most complete subsystems:
|
|
||||||
|
|
||||||
- On-demand blob loading via `scheme:firmware`
|
|
||||||
- Indexes `/lib/firmware` at startup
|
|
||||||
- Persistent cache with fallback chains
|
|
||||||
- Async `request_firmware_nowait()` with timeout and retry
|
|
||||||
- Emits uevents for consumers
|
|
||||||
- Read-only scheme with mmap support
|
|
||||||
|
|
||||||
Source: `local/recipes/system/firmware-loader/source/`
|
|
||||||
|
|
||||||
The boot log does not show firmware loading activity because no device requested
|
|
||||||
firmware during this boot (no GPU, no Wi-Fi).
|
|
||||||
|
|
||||||
**Verdict**: This subsystem is **production-ready** architecturally. Needs
|
|
||||||
hardware validation when GPU/Wi-Fi drivers are active.

|
||||||

### 2.9 Memory Management
|
|
||||||
|
|
||||||
**Status**: 🟡 Basic but functional; **advanced features missing**
|
|
||||||
**Linux 7.1 equivalent**: `mm/`, `arch/x86/mm/`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
- Frame allocator / buddy-like free list
|
|
||||||
- Kernel page-table setup (4-level on x86_64)
|
|
||||||
- Device-memory mapping for MMIO
|
|
||||||
- Explicit memory-region handling
|
|
||||||
- Early boot memory map parsing from ACPI/firmware
|
|
||||||
- 7,092 MB detected in boot log
|
|
||||||
|
|
||||||
Source:
|
|
||||||
- `recipes/core/kernel/source/src/memory/mod.rs`
|
|
||||||
- `recipes/core/kernel/source/src/startup/memory.rs`
|
|
||||||
|
|
||||||
#### What is missing
|
|
||||||
|
|
||||||
| Feature | Linux 7.1 | Red Bear |
|
|
||||||
|---------|-----------|----------|
|
|
||||||
| Swap | Full swap with page reclaim | Not implemented |
|
|
||||||
| NUMA | Node-aware allocation, migrate pages | No NUMA awareness |
|
|
||||||
| Memory hotplug | Add/remove memory at runtime | Not implemented |
|
|
||||||
| Reclaim/compaction | `kswapd`, memory pressure handling | Not implemented |
|
|
||||||
| OOM killer | `out_of_memory()` kills processes | Not implemented |
|
|
||||||
| Huge pages | THP, hugetlbfs | Not implemented |
|
|
||||||
| Memory cgroups | `memcg` resource limits | Not implemented |
|
|
||||||
| Demand paging | Lazy allocation on fault | Basic but no swap backing |
|
|
||||||
|
|
||||||
**Verdict**: Sufficient for current boot and userspace needs, but not
|
|
||||||
production-grade for memory-intensive workloads.
|
|
||||||

|
|
||||||
|
|
||||||
### 2.10 Logging Infrastructure
|
|
||||||
|
|
||||||
**Status**: 🟡 Basic append-only; **no rotation, no structured storage**
|
|
||||||
**Linux 7.1 equivalent**: No direct equivalent; compare to `systemd-journald`,
|
|
||||||
`rsyslog`, `syslog-ng`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
- `logd` daemon serves `scheme:log`
|
|
||||||
- Persists to `/var/log/system.log`
|
|
||||||
- prepends startup banner, backfills new sinks
|
|
||||||
- Mirrors kernel log input
|
|
||||||
- relibc syslog API (`syslog()`, `openlog()`) writes to `/scheme/log`
|
|
||||||
|
|
||||||
Source:
|
|
||||||
- `recipes/core/base/source/logd/src/main.rs`
|
|
||||||
- `recipes/core/base/source/logd/src/scheme.rs`
|
|
||||||
|
|
||||||
#### What is weak
|
|
||||||
|
|
||||||
| Issue | Detail |
|
|
||||||
|-------|--------|
|
|
||||||
| Append-only | `/var/log/system.log` grows forever |
|
|
||||||
| No rotation | No size-based or time-based truncation |
|
|
||||||
| No retention | Old logs never deleted |
|
|
||||||
| No structured format | Plain text only; no JSON or binary journal |
|
|
||||||
| read path TODO | `scheme.rs` has a TODO for reading log history |
|
|
||||||
| Console dominance | Most daemon output still goes to console timestamps |
|
|
||||||
| No per-service logs | All logs in one file |
|
|
||||||
|
|
||||||
The boot log shows console timestamps because daemons write to stderr, which
|
|
||||||
init captures and logs. The persistent `/var/log/system.log` exists but is
|
|
||||||
append-only with no management.
|
|
||||||
|
|
||||||
**Verdict**: Functional for debugging but not suitable for production
|
|
||||||
observability. Needs rotation, structured format, and per-service separation.

### 2.11 Udev / Device Discovery
|
|
||||||
|
|
||||||
**Status**: 🟡 Real but **limited**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/base/core.c`, `lib/kobject_uevent.c`, `udev/`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
`udev-shim` is a **real implementation**, not a placeholder:
|
|
||||||
|
|
||||||
- Enumerates PCI devices via `pcid` scheme
|
|
||||||
- Classifies devices by class/subclass/vendor
|
|
||||||
- Creates `/dev` nodes and symlinks
|
|
||||||
- Writes `/etc/udev/rules.d/50-default.rules`
|
|
||||||
- Exposes `scheme:udev`
|
|
||||||
- Polls for changes (not event-driven)
|
|
||||||
|
|
||||||
Source: `local/recipes/system/udev-shim/source/`
|
|
||||||
|
|
||||||
The boot log shows:
|
|
||||||
|
|
||||||
```
|
|
||||||
[ OK ] Started udev compatibility shim
|
|
||||||
[INFO] udev-shim: enumerated 1 PCI device(s)
|
|
||||||
[INFO] udev-shim: wrote default rules to /etc/udev/rules.d/50-default.rules
|
|
||||||
```
|
|
||||||
|
|
||||||
#### What is weak
|
|
||||||
|
|
||||||
| Issue | Detail |
|
|
||||||
|-------|--------|
|
|
||||||
| Hardcoded rules | Only 3 rules: net naming (`enp*`), NVMe by-id, SATA by-id |
|
|
||||||
| Polling hotplug | Polls every N seconds; not event-driven like Linux udev/netlink |
|
|
||||||
| No rules engine | Cannot parse Linux udev rules; rules are compiled-in |
|
|
||||||
| libudev-stub TODO | `local/recipes/libs/libudev-stub/recipe.toml` explicitly marked TODO |
|
|
||||||
| Limited coverage | Only PCI devices; no USB, no ACPI, no platform devices |
|
|
||||||
| No persistent db | Device state not saved across reboots |
|
|
||||||
|
|
||||||
Linux 7.1 udev:
|
|
||||||
- Event-driven via netlink `NETLINK_KOBJECT_UEVENT`
|
|
||||||
- Full rules engine with `MATCH`, `ACTION`, `ENV`, `RUN`
|
|
||||||
- Persistent database in `/run/udev/`
|
|
||||||
- `udevadm` tool for querying and triggering
|
|
||||||
- Integrates with `systemd` for device units
|
|
||||||
|
|
||||||
**Verdict**: Functional for basic PCI device naming but far from a full udev
|
|
||||||
replacement. Polling hotplug is inefficient.

### 2.12 Input Stack
|
|
||||||
|
|
||||||
**Status**: 🟡 Real but **uneven quality**
|
|
||||||
**Linux 7.1 equivalent**: `drivers/input/`, `drivers/hid/`, `drivers/serio/`
|
|
||||||
|
|
||||||
#### What is real
|
|
||||||
|
|
||||||
| Component | Status | Detail |
|
|
||||||
|-----------|--------|--------|
|
|
||||||
| `ps2d` | Real | PS/2 keyboard + mouse; kernel serio byte queues |
|
|
||||||
| `usbhidd` | Real | HID report parsing, named producers |
|
|
||||||
| `inputd` | Real | Producer/consumer scheme, VT switching, keymaps |
|
|
||||||
| `evdevd` | Real | evdev scheme, orbclient→evdev translation |
|
|
||||||
| `i2c-hidd` | Real | ACPI PNP0C50 scan, _CRS parsing |
|
|
||||||
| `intel-thc-hidd` | Partial | PCI init works; main loop sleeps 5s — **no input streaming** |
|
|
||||||
|
|
||||||
The boot log shows PS/2 and evdev working:
|
|
||||||
|
|
||||||
```
|
|
||||||
[ OK ] Started PS/2 driver
|
|
||||||
[ OK ] Started Evdev input daemon
|
|
||||||
[INFO] evdevd: registered scheme:evdev
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Gaps vs Linux 7.1
|
|
||||||
|
|
||||||
| Gap | Severity | Linux Reference |
|
|
||||||
|-----|----------|-----------------|
|
|
||||||
| intel-thc-hidd no streaming | **High** | `drivers/hid/intel-thc-hid/` full probe+report |
|
|
||||||
| No multitouch/ABS_MT | **High** | `drivers/input/input-mt.c` |
|
|
||||||
| No libinput acceleration | **High** | libinput: velocity curves, palm detection |
|
|
||||||
| No PS/2 extended protocols | Medium | `libps2.c` ImPS/2 scroll, Explorer 5-btn |
|
|
||||||
| No HID quirks table | Medium | `hid-quirks.c` 4000+ entries |
|
|
||||||
| No input hotplug | Medium | udev + inotify on `/dev/input/` |
|
|
||||||
|
|
||||||
**Verdict**: The input stack exists and works for basic keyboard/mouse. Touch
|
|
||||||
and advanced HID are incomplete.

|

## 3. Root Cause Analysis
|
|
||||||
|
|
||||||
### Why the system runs hot on bare metal
|
|
||||||
|
|
||||||
1. **No C-state management** → CPUs never enter low-power idle states (C1, C1E,
|
|
||||||
C3, C6, C7). They spin in the kernel idle loop at full power.
|
|
||||||
2. **No ACPI thermal zones** → `acpid` does not enumerate thermal zones, so
|
|
||||||
`thermald` has no temperature data to act on.
|
|
||||||
3. **No hwmon sensor drivers** → No temperature sensors are readable. The system
|
|
||||||
is "flying blind."
|
|
||||||
4. **No ACPI fan control** → Fan devices are not enumerated, so `thermald`
|
|
||||||
cannot turn on cooling.
|
|
||||||
5. **cpufreqd MSR writes failing** → Even P-state throttling is not working
|
|
||||||
reliably (`MSR write failed` in boot log).
|
|
||||||
|
|
||||||
**Fix priority**: C-states (immediate heat reduction) > ACPI thermal zones
|
|
||||||
(enables thermald) > hwmon sensors (operator visibility) > fan control
|
|
||||||
(active cooling).
|
|
||||||
|
|
||||||
### Why only 1 CPU shows online
|
|
||||||
|
|
||||||
1. **QEMU i440fx** exposes only 1 vCPU by default (most likely in the provided
|
|
||||||
boot log)
|
|
||||||
2. **AP startup races** — LogicalCpuId race, missing SIPI delays, AP_READY dual
|
|
||||||
mechanism can cause APs to fail startup on real hardware
|
|
||||||
3. **MAX_CPU_COUNT=128** too small for high-core-count AMD EPYC
|
|
||||||
4. No bare-metal validation means we don't know which of these is the real
|
|
||||||
blocker on actual hardware
|
|
||||||
|
|
||||||
### Why USB keyboard may not work on bare metal
|
|
||||||
|
|
||||||
1. **Only xHCI exists** — no EHCI/UHCI/OHCI drivers
|
|
||||||
2. Many systems route USB 2.0 keyboards through EHCI
|
|
||||||
3. Some AMD/VIA systems use OHCI for legacy ports
|
|
||||||
4. Some Intel systems use UHCI for legacy ports
|
|
||||||
5. No companion controller support to route low-speed devices from EHCI to xHCI
|
|
||||||

## 5. New Improvement Plan
|
|
||||||
|
|
||||||
This plan is ordered by **impact on bare-metal usability** and **dependency
|
|
||||||
chain**. Earlier phases unblock later ones.
|
|
||||||
|
|
||||||
### Phase 1: Bare-Metal Boot Hardening (6–8 weeks)
|
|
||||||
**Goal**: Boot reliably on diverse bare metal with all cores, reasonable
|
|
||||||
temperature, and working USB keyboard.
|
|
||||||
|
|
||||||
#### 1.1 Fix SMP AP Startup (2 weeks)
|
|
||||||
- [ ] Fix K1 (LogicalCpuId race) — use `fetch_add` before AP reads ID
|
|

### Phase 5: Hardware Validation Matrix (4–6 weeks)
|
|
||||||
**Goal**: Evidence-based support claims.
|
|
||||||
|
|
||||||
#### 5.1 Define Validation Targets
|
|
||||||
Minimum 4 hardware classes:
|
|
||||||
1. AMD desktop (Ryzen, discrete GPU)
|
|
||||||
2. Intel desktop (Core, integrated GPU)
|
|
||||||
3. AMD laptop (Ryzen mobile)
|
|
||||||
4. Intel laptop (Core mobile)
|
|
||||||
|
|
||||||
#### 5.2 Per-Target Checklist
|
|
||||||
For each target, validate and record:
|
|
||||||
- [ ] Boots to login prompt
|
|
||||||
- [ ] All CPU cores online (`SMP: N CPUs online` matches hardware)
|
|
||||||
- [ ] USB keyboard works at boot
|
|
||||||
- [ ] USB storage mounts
|
|
||||||
- [ ] Network (wired) obtains DHCP lease
|
|
||||||
- [ ] Temperature readable via `redbear-info`
|
|
||||||
- [ ] Shutdown succeeds cleanly
|
|
||||||
- [ ] Reboot succeeds cleanly
|
|
||||||
|
|
||||||
#### 5.3 Negative-Result Capture
|
|
||||||
- [ ] Document failures per target (e.g., "AMD X670E: AP startup timeout",
|
|
||||||
"Intel Raptor Lake: SMBIOS missing")
|
|
||||||
- [ ] Update this assessment with validation evidence
|
|
||||||
|
|
||||||
### Phase 6: Desktop Stack Continuation (Parallel)
|
|
||||||
**Goal**: Continue the CONSOLE-TO-KDE path on top of hardened substrate.
|
|
||||||
|
|
||||||
This phase is **orthogonal** to the low-level work above. It depends on:
|
|
||||||
- Qt6Quick/QML downstream proof (unblocks kirigami)
|
|
||||||
- Real KWin build
|
|
||||||
- GPU CS ioctl backend + Mesa HW cross-compile
|
|
||||||
|
|
||||||
See `CONSOLE-TO-KDE-DESKTOP-PLAN.md` for detailed desktop path planning.

|
|
||||||
## 7. Evidence Model
|
|
||||||
|
|
||||||
This assessment uses the same evidence vocabulary as the canonical subsystem
|
|
||||||
plans:
|
|
||||||
|
|
||||||
| Class | Meaning |
|
|
||||||
|-------|---------|
|
|
||||||
| **Source-visible** | Behavior visible in checked-in source |
|
|
||||||
| **Build-visible** | Code compiles and stages in current build |
|
|
||||||
| **QEMU-validated** | Behavior exercised successfully in QEMU |
|
|
||||||
| **Runtime-validated** | Behavior exercised in real boot/runtime |
|
|
||||||
| **Hardware-validated** | Behavior proven on named bare-metal hardware |
|
|
||||||
| **Negative-result-documented** | Failures and gaps are explicitly recorded |
|
|
||||||
|
|
||||||
**No subsystem in this assessment is marked "hardware-validated"** because no
|
|
||||||
component has been proven on real bare metal with the rigor defined in
|
|
||||||
`ACPI-IMPROVEMENT-PLAN.md` Wave 7.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 8. Definition of Done
|
|
||||||
|
|
||||||
This plan is complete when:
|
|
||||||
|
|
||||||
1. SMP brings up all cores reliably on AMD and Intel bare metal
|
|
||||||
2. C-states reduce idle power consumption measurably
|
|
||||||
3. ACPI thermal zones are readable and thermald responds to trip points
|
|
||||||
4. At least 2 sensor drivers report temperature on bare metal
|
|
||||||
5. EHCI driver enables USB keyboard on systems without xHCI routing
|
|
||||||
6. MSI-X is adopted by all new PCI drivers; legacy IRQ is documented fallback
|
|
||||||
7. IOMMU validates on at least one AMD and one Intel platform
|
|
||||||
8. Logging has rotation and per-service separation
|
|
||||||
9. Udev-shim supports event-driven hotplug
|
|
||||||
10. A validation matrix with 4+ hardware targets is published and maintained
|

# Red Bear OS — CPU/DMA/IRQ/MSI/Scheduler Fix Plan
|
||||||
|
|
||||||
|
**Date**: 2026-05-04
|
||||||
|
**Updated**: 2026-05-04 (MSI T1.1–T2.2 implemented, committed, pushed)
|
||||||
|
**Status**: Active — MSI Phase 1 complete, DMA/Scheduler pending
|
||||||
|
**Source of truth**: Linux kernel 7.0 (local/reference/linux-7.0/)
|
||||||
|
|
||||||
|
## 1. Problem Statement
|
||||||
|
|
||||||
|
Five critical integration gaps in the microkernel architecture:
|
||||||
|
|
||||||
|
| Gap | Severity | Impact | Status |
|
||||||
|
|-----|----------|--------|--------|
|
||||||
|
| MSI absent from kernel | CRITICAL | All NVMe/GPU/NIC on legacy INTx | ✅ RESOLVED (P8-msi.patch) |
|
||||||
|
| DMA/IOMMU not integrated | CRITICAL | DMA buffers unprotected | ⏳ Pending |
|
||||||
|
| PIT tick (148Hz) vs LAPIC (1000Hz) | HIGH | Scheduler 6x slower than Linux | ✅ RESOLVED (P7-scheduler patch) |
|
||||||
|
| Global scheduler lock | HIGH | Serializes all context switches | ✅ RESOLVED (work-stealing) |
|
||||||
|
| Thread creation (3 IPC hops) | HIGH | 3x slower than Linux clone() | ⏳ Pending |
|
||||||
|
|
||||||
|

|
||||||
|
- Bounds-safe: all `parse()` methods return `Option<Self>`, using `.get()` instead of raw indexing
|
||||||
|
|
||||||
|

|
||||||
|
- Implements: `Handle::IrqAffinity { irq, mask }` variant, path routing for `<irq>/affinity` and `cpu-XX/<irq>/affinity`, kwrite validates CPU id and stores mask atomically, kfstat/kfpath/kreadoff/close all handle new variant
|
||||||
|
|
||||||
|
## 3. Phase 2: DMA/IOMMU Integration (Week 3-5) — AUDITED 2026-05-04
|
||||||
|
|
||||||
|
**Status**: IOMMU daemon (1003 lines) and DmaBuffer (261 lines) already exist and are solid. Tasks re-scoped from "create" to "wire."

|
||||||
|
- Add `IommuDmaAllocator` struct: holds IOMMU domain fd, wraps `DmaBuffer::allocate()` with IOMMU MAP opcode
|
||||||
|
- Uses `scheme:iommu/domain/N` write with MAP request → get IOVA
|
||||||
|
- Linux ref: `include/linux/dma-mapping.h` — `dma_alloc_coherent()` → `iommu_dma_alloc()`
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### T2.3: Streaming DMA (linux-kpi) ⏳ P1

|
||||||
|
- Linux ref: `kernel/dma/mapping.c` — streaming API
|
||||||
|

|
||||||
|
- Linux ref: `kernel/dma/swiotlb.c`
|
||||||
|
- Bounce buffer for devices with <4GB DMA addressing

|
||||||
|
- FIFO and Round-Robin classes
|
||||||
|
- Priority inheritance

||||||
|
|
||||||
|
**Date**: 2026-05-04
|
||||||
|
**Status**: Authoritative — supersedes CHANGELOG-DRIVER-IMPROVEMENT-PLAN.md, COMPREHENSIVE-DRIVER-AUDIT-2026-05-04.md, and HARDWARE-VALIDATION-MATRIX.md
|
||||||
|
**Source of truth**: Linux kernel 7.0 (`local/reference/linux-7.0/`)

||||||
|
## 1. Authority & Scope
|
||||||
|
|
||||||
|
### 1.1 Relationship to Existing Plans
|
||||||
|
|
||||||
|
This plan is the **master execution document**. It delegates subsystem authority to specialized plans:
|
||||||
|
|
||||||
|
| Plan | Subsystem | Relationship |
|
||||||
|
|------|-----------|-------------|
|
||||||
|
| `ACPI-IMPROVEMENT-PLAN.md` | ACPI sleep, thermal, EC, power | **Authoritative** for ACPI |
|
||||||
|
| `IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md` | PCI IRQ, MSI-X, IOMMU, controllers | **Authoritative** for IRQ/PCI |
|
||||||
|
| `USB-IMPLEMENTATION-PLAN.md` | xHCI, EHCI, device lifecycle | **Authoritative** for USB |
|
||||||
|
| `DRM-MODERNIZATION-EXECUTION-PLAN.md` | GPU/DRM, KMS, Mesa | **Authoritative** for GPU |
|
||||||
|
| `BLUETOOTH-IMPLEMENTATION-PLAN.md` | BT host/controller | **Authoritative** for BT |
|
||||||
|
| `WIFI-IMPLEMENTATION-PLAN.md` | Wi-Fi control plane | **Authoritative** for Wi-Fi |
|
||||||
|
| `CONSOLE-TO-KDE-DESKTOP-PLAN.md` | Desktop/KDE path | **Authoritative** for desktop |
|
||||||
|
|
||||||
|
**This master plan covers**: storage, network, audio, input drivers, cross-cutting quality, CPU/power, virtio, and kernel substrate (CPU/SMP/timers/DMA/memory).
|
||||||
|
|
||||||
|
### 1.2 Validation Levels
|
||||||
|
|
||||||
|
- **builds** — compiles without error
|
||||||
|
- **enumerates** — discovers hardware via scheme interfaces
|
||||||
|
- **usable** — works in bounded scenario (QEMU or bare metal)
|
||||||
|
- **validated** — passes explicit acceptance tests with evidence
|
||||||
|
- **hardware-validated** — proven on real bare metal

### K2: DMA / IOMMU (Audited 2026-05-04)
|
||||||
|
|
||||||
|
**Current State — Thorough Audit:**
|
||||||
|
|
||||||
|
| Component | Location | Lines | Status |
|
||||||
|
|---|---|---|---|
|
||||||
|
| IOMMU scheme daemon | `local/recipes/system/iommu/source/src/lib.rs` | 1,003 | ✅ REAL — full AMD-Vi protocol: domain CRUD, MAP/UNMAP/TRANSLATE, device assignment, event drain, IRQ remapping. Host-runnable tests pass. |
|
||||||
|
| AMD-Vi unit driver | `local/recipes/system/iommu/source/src/amd_vi.rs` | 427 | ✅ REAL — IVRS parsing, MMIO mapping, device table programming, command buffer, event log, page table init |
|
||||||
|
| Domain page tables | `local/recipes/system/iommu/source/src/page_table.rs` | — | ✅ REAL — multi-level page table, IOVA allocation, mapping flags (R/W/X/coherent/user) |
|
||||||
|
| DMA buffer (alloc+phys) | `local/recipes/drivers/redox-driver-sys/source/src/dma.rs` | 261 | ✅ REAL — `DmaBuffer` with physically contiguous allocation via scheme:memory, virt-to-phys translation, heap fallback |
|
||||||
|
| linux-kpi DMA headers | `local/recipes/drivers/linux-kpi/source/` | — | ✅ dma-mapping.h, dma-direction.h, scatterlist.h ported |
|
||||||
|
| IOMMU←→driver wiring | — | — | ❌ **GAP** — `DmaBuffer` does NOT pass through IOMMU domains. GPU/NIC/NVMe drivers allocate DMA directly, not through IOMMU-isolated domains |
|
||||||
|
| Streaming DMA | — | — | ❌ **GAP** — no `dma_map_single`/`dma_unmap_single` for bounce-buffer ops |
|
||||||
|
| SWIOTLB | — | — | ❌ **GAP** — no bounce buffer for devices with limited DMA range |
|
||||||
|
|
||||||
|
**Implementation Plan — DMA/IOMMU Integration (Week 3-5):**
|
||||||
|
|
||||||
|
| Task | Description | Lines | Priority |
|
||||||
|
|---|---|---|---|
|
||||||
|
| **D2.1: IommuDmaAllocator** | New type in driver-sys: takes an IOMMU domain handle, allocates DmaBuffer through it. Uses `scheme:iommu/domain/N` MAP opcode. | ~150 | P0 |
|
||||||
|
| **D2.2: GPU DMA pass-through** | Wire `redox-drm` to use `IommuDmaAllocator` for GTT/VRAM allocations. Requires amdgpu/ihdgd to open IOMMU device handle. | ~80 | P0 |
|
||||||
|
| **D2.3: NVMe DMA pass-through** | Wire `ahcid`/`nvmed` PRP lists through `IommuDmaAllocator`. | ~60 | P1 |
|
||||||
|
| **D2.4: Streaming DMA** | `dma_map_single`/`dma_unmap_single` in linux-kpi. Allocates temp buffer, copies data, maps through IOMMU. | ~120 | P1 |
|
||||||
|
| **D2.5: SWIOTLB** | Bounce buffer allocation for DMA-limited devices. Linux ref: `kernel/dma/swiotlb.c`. | ~200 | P2 |
|
||||||
|
|
||||||
|
**Linux Reference Summary (from `local/reference/linux-7.0/`):**
|
||||||
|
|
||||||
|
| Linux API | Purpose | Red Bear Equivalent |
|
||||||
|
|---|---|---|
|
||||||
|
| `dma_alloc_coherent()` | Allocate physically contiguous, uncached DMA buffer | `DmaBuffer::allocate()` + `IommuDmaAllocator` (planned) |
|
||||||
|
| `dma_map_single()` | Map a single buffer for device DMA (cache sync) | Not yet — D2.4 |
|
||||||
|
| `dma_map_sg()` | Map scatter-gather list | Not yet |
|
||||||
|
| `iommu_domain_alloc()` | Create IOMMU translation domain | `IommuScheme` CREATE_DOMAIN opcode |
|
||||||
|
| `iommu_map()` | Map physical pages into domain | `IommuScheme` MAP opcode |
|
||||||
|
| `iommu_attach_device()` | Assign device to domain | `IommuScheme` ASSIGN_DEVICE opcode |
|
||||||
|
|
||||||
|
### K2b: Thread Creation / fork() (Audited 2026-05-04)
|
||||||
|
|
||||||
|
**Current State:**
|
||||||
|
|
||||||
|
| Component | Location | Lines | Status |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Kernel `context::spawn` | `recipes/core/kernel/source/src/context/mod.rs:217` | ~25 | ✅ Creates new context with NEW address space, kernel stack, initial call frame |
|
||||||
|
| `scheme:user` process spawn | `recipes/core/kernel/source/src/scheme/user.rs:723` | — | ✅ Userspace writes process params → kernel spawns |
|
||||||
|
| relibc `rlct_clone` | `recipes/core/relibc/source/src/platform/redox/mod.rs:1154` | ~10 | ✅ Thread creation via `redox_rt::thread::rlct_clone_impl` — lightweight: shares address space, TCB, signal state |
|
||||||
|
| `pthread_create` | `recipes/core/relibc/source/src/pthread/mod.rs:105` | ~100 | ✅ Allocates stack via mmap, creates TCB, calls rlct_clone |
|
||||||
|
| Thread stack allocation | mmap-based (line 130-143) | — | ✅ MAP_PRIVATE | MAP_ANONYMOUS, correct |
|
||||||
|
|
||||||
|
**Gap Analysis:**
|
||||||
|
|
||||||
|
| Gap | Severity | Detail |
|
||||||
|
|---|---|---|
|
||||||
|
| No `clone()` syscall | MEDIUM | Redox uses `rlct_clone` for threads and `scheme:user` for processes. This is architecturally correct for a microkernel — no gap. |
|
||||||
|
| No `CLONE_VM` flag | N/A | `rlct_clone` implicitly shares address space (it's a THREAD clone, not a process clone). Process creation via `scheme:user` creates new address space. Correct semantics. |
|
||||||
|
| No `CLONE_FILES` | N/A | File descriptors are shared via the `scheme:user` write protocol. Re-layout possible but functional. |
|
||||||
|
| "3 IPC hops" slower than Linux | LOW | Measured: 1) mmap stack, 2) rlct_clone syscall, 3) synchronization mutex unlock. Linux `clone()` does all three in kernel. Acceptable for a microkernel. |
|
||||||
|
| No `posix_spawn()` fast-path | MEDIUM | Currently goes through `fork`-equivalent → `exec`. Linux has `posix_spawn` via `vfork`+`exec`. Not yet in Redox. |
|
||||||
|
|
||||||
|
**Overall verdict on DMA/IOMMU**: IOMMU daemon is the most complete userspace component — it needs wiring, not rewriting. DmaBuffer exists but is IOMMU-unaware. The implementation tasks (D2.1-D2.5) are wiring tasks connecting an already-working IOMMU to already-working driver allocators.

## 14. Scheduler & Threading Assessment (2026-05-04)
|
||||||
|
|
||||||
|
### Architecture
|
||||||
|
- **Kernel**: DWRR scheduler (577 lines), 40 priority levels, per-CPU queues, futex (222 lines)
|
||||||
|
- **Userspace**: proc manager (2,638 lines), pthread (440 lines), signal delivery via proc scheme
|
||||||
|
- **IPC bridge**: 3 round-trips for thread creation vs Linux's single clone() syscall
|
||||||
|
|
||||||
|
### Strengths
|
||||||
|
- DWRR with geometric weights, CPU affinity masks, soft-blocking with monotonic timeout
|
||||||
|
- Full POSIX process model (PID/PGID/SID, job control, orphan detection)
|
||||||
|
- Futex with physical-address keys for cross-process synchronization
|
||||||
|
|
||||||
|
### Critical Gaps
|
||||||
|
1. **PIT-based tick (~148Hz)** — LAPIC timer exists but `setup_timer()` is commented out. Should use Periodic/TscDeadline mode at 1000Hz.
|
||||||
|
2. **Global CONTEXT_SWITCH_LOCK** — spinlock serializes all context switches across CPUs. Should be per-CPU.
|
||||||
|
3. **No load balancing** — idle CPUs don't steal work from busy CPUs
|
||||||
|
4. **No RT scheduling** — missing FIFO/RR/Deadline classes
|
||||||
|
5. **No cgroups** — no CPU bandwidth control or resource limits
|
||||||
|
6. **Thread creation latency** — 3 IPC hops vs single clone()

## 1. Executive Summary
|
|
||||||
|
|
||||||
This document is a **code-grounded reassessment** of four interdependent low-level subsystems: ACPI/acpid, IRQ/PCI, enumeration/driver binding, and driver infrastructure. It is based on direct source inspection (file paths and line numbers provided throughout), cross-referenced against existing plans.
|
|
||||||
|
|
||||||
### Bottom-line verdict
|
|
||||||
|
|
||||||
| Subsystem | Verdict | Blocking Bare Metal? |
|
|
||||||
|-----------|---------|---------------------|
|
|
||||||
| **ACPI boot** | Boot-baseline complete, not release-grade | Partial — shutdown timing fragile |
|
|
||||||
| **ACPI shutdown** | S5 derivation works, timing-dependent on PCI | Yes — pre-PCI shutdown degrades weakly |
|
|
||||||
| **ACPI thermal/fan** | Discovery exists, no runtime backend | No — thermal safety gap |
|
|
||||||
| **ACPI C-states** | Discovery exists, **no kernel cpuidle** | **Yes** — root cause of heat |
|
|
||||||
| **IRQ delivery** | Architecturally strong, QEMU-proven only | Partial — no HW validation |
|
|
||||||
| **MSI/MSI-X** | Code complete, **IOMMU validation stubbed** | **Yes** — `iommu_validate_msi_irq()` returns `true` |
|
|
||||||
| **PCI enumeration** | Userspace-only (correct), pcid complete | No |
|
|
||||||
| **Driver binding** | Manual class-code matching, no ACPI _HID/_CID | Partial — limited device coverage |
|
|
||||||
| **redox-driver-sys** | Production quality, zero stubs | No |
|
|
||||||
| **linux-kpi** | Structurally complete for GPU+Wi-Fi | No |
|
|
||||||
| **GPU drivers** | Compile-only, synthetic EDID everywhere | **Yes** — no real display detection |
|
|
||||||
| **Wi-Fi** | Compile+host-test only | Yes — no HW validation |
|
|
||||||
| **USB** | xhcid only, no EHCI/UHCI/OHCI | **Yes** — legacy USB keyboards unreachable |
|
|
||||||
|
|
||||||
### What changed since last assessment (2026-05-20)
|
|
||||||
|
|
||||||
1. **Critical stub discovered**: `iommu_validate_msi_irq()` at `kernel/src/scheme/irq.rs:231` unconditionally returns `true` — this was not flagged as a blocking item in the IRQ enhancement plan (all 6 waves marked "complete").
|
|
||||||
2. **Critical stub discovered**: `aml_physmem.rs:195` and `:274` fabricate zero values on physical memory access failure — affects all AML runtime evaluation.
|
|
||||||
3. **Dual AML interpreter architecture** identified as a maintenance risk — kernel `acpi_ext` crate and userspace `acpi` crate parse DSDT/SSDT independently.
|
|
||||||
4. **APIC timer disabled** (`local_apic.rs:81`) — not flagged in any existing plan as a blocker.
|
|
||||||
5. **Synthetic EDID used in all GPU drivers** — blocks real display detection on bare metal.
|
|
||||||
6. **40 total TODOs** in ACPI code (16 kernel + 24 userspace) — higher than previously documented.

## 2. ACPI / acpid Reassessment
|
|
||||||
|
|
||||||
### 2.1 Architecture
|
|
||||||
|
|
||||||
The ACPI subsystem has **three operational levels**:
|
|
||||||
|
|
||||||
```
|
|
||||||
Bootloader → KernelArgs.hwdesc_base (RSDP pointer)
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Kernel ACPI (src/acpi/ + src/scheme/acpi.rs + src/arch/x86_shared/sleep.rs)
|
|
||||||
├── RSDP→RSDT/XSDT→SDT enumeration (MADT, SRAT, SLIT, HPET)
|
|
||||||
├── Export via /scheme/kernel.acpi/{rxsdt, kstop, sleep}
|
|
||||||
└── Kernel-side AML interpreter (acpi_ext crate) for S3/S5 sleep
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Userspace acpid (drivers/acpid/src/)
|
|
||||||
├── Reads rxsdt, loads SDTs from physical memory
|
|
||||||
├── Userspace AML interpreter (acpi crate) — SEPARATE from kernel's
|
|
||||||
├── Exports /scheme/acpi/{dmi, tables, symbols, thermal, fan, cstates}
|
|
||||||
└── Shutdown via kstop pipe + PM1a/PM1b write
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2.2 What Is Working
|
|
||||||
|
|
||||||
| Component | File | Evidence |
|
|
||||||
|-----------|------|----------|
|
|
||||||
| RSDP discovery + dual checksum | `acpi/rsdp.rs` | ACPI 1.0 + 2.0+ validation, 62 lines |
|
|
||||||
| MADT parsing (10 entry types) | `acpi/madt/mod.rs` | Types 0x0–0xA + aarch64 GICC/GICD, 340 lines |
|
|
||||||
| x2APIC support | `acpi/madt/mod.rs` | Types 0x9/0xA, `P20–P22` patches |
|
|
||||||
| IOAPIC init from MADT | `device/ioapic.rs` | GSI resolution, source overrides, affinity, 502 lines |
|
|
||||||
| LAPIC/x2APIC | `device/local_apic.rs` | MSR + MMIO dual path, 312 lines |
|
|
||||||
| SRAT/SLIT NUMA | `acpi/srat.rs`, `acpi/slit.rs` | Affinity + distance matrix |
|
|
||||||
| HPET timer | `acpi/hpet.rs` | Init from ACPI tables |
|
|
||||||
| Kernel scheme export | `scheme/acpi.rs` | rxsdt, kstop, sleep — 398 lines |
|
|
||||||
| acpid SDT loading | `acpid/src/acpi.rs:162–217` | Page-span handling, PhysmapGuard |
|
|
||||||
| acpid FADT parsing | `acpid/src/acpi.rs:965–1122` | ACPI 2.0 extended fields |
|
|
||||||
| acpid EC handler | `acpid/src/ec.rs` | Full protocol (RD_EC/WR_EC/BE_EC/BD_EC/QR_EC), 317 lines |
|
|
||||||

|
|
||||||
| acpid DMI | `acpid/src/dmi.rs` | SMBIOS 32/64-bit entry points, 350 lines |
|
|
||||||
| acpid thermal/fan/cstate discovery | `thermal.rs`, `fan.rs`, `cstate.rs` | AML-backed \__TZ, \__PR namespace |
|
|
||||||
| hwd ACPI backend | `hwd/backend/acpi.rs` | \__CID/\__HID device discovery, 119 lines |
|
|
||||||
|
|
||||||
### 2.3 Critical Stubs
|
|
||||||
|
|
||||||
| Location | Line | Issue | Severity |
|
|
||||||
|----------|------|-------|----------|
|
|
||||||
| `acpid/src/aml_physmem.rs` | 195 | `read_phys_or_fault()` returns `T::zero()` on failure — **fabricates data** | 🔴 CRITICAL |
|
|
||||||
| `acpid/src/aml_physmem.rs` | 274 | `map_physical_region()` falls back to **zero page** on failure — writes lost | 🔴 CRITICAL |
|
|
||||||
| `kernel/src/arch/x86_shared/sleep.rs` | 257–276 | `read_pci_u8/u16/u32` always return **0**; `write_pci_*` are no-ops | 🔴 CRITICAL |
|
|
||||||
| `kernel/src/arch/x86_shared/sleep.rs` | 275 | `nanos_since_boot()` returns **0** — broken AML timing | 🟠 HIGH |
|
|
||||||
| `kernel/src/arch/x86_shared/sleep.rs` | 294–298 | `acquire()`/`release()` for AML mutexes are **no-ops** | 🟠 HIGH |
|
|
||||||
| `acpid/src/acpi.rs` | 545 | `Dmar::init(&this)` **commented out** — "TODO (hangs on real hardware)" | 🟠 HIGH |
|
|
||||||
| `hwd/backend/legacy.rs` | 13 | `LegacyBackend::probe()` is a **TODO no-op** | 🟠 HIGH |
|
|
||||||
| `acpid/src/acpi.rs` | 820–822 | `set_global_s_state(state)` returns `Ok` for any state != 5 | 🟡 MEDIUM |
|
|
||||||
|
|
||||||
### 2.4 Architectural Risks
|
|
||||||
|
|
||||||
1. **Dual AML interpreters**: Kernel `sleep.rs` uses `acpi_ext` crate; userspace `acpid` uses `acpi` crate. They parse the same DSDT/SSDT independently with different handler implementations. Bug fixes in one do not affect the other.
|
|
||||||
2. **RSDP_ADDR contract**: acpid AML init requires `RSDP_ADDR` environment variable (from `hwd` via `KernelArgs.hwdesc_base`). x86 has BIOS fallback; non-x86 paths are unresolved.
|
|
||||||
3. **S5 derivation timing**: Depends on AML readiness which depends on PCI registration. Pre-PCI shutdown falls back gracefully but the degraded contract is weak.
|
|
||||||
4. **DMAR orphaned**: 533 lines of Intel VT-d parsing code exist but are not wired into startup.
|
|
||||||
|
|
||||||
### 2.5 TODO Inventory
|
|
||||||
|
|
||||||
- **Kernel ACPI**: 16 TODOs (`madt` arch variants, `hpet` x86 assumption, `spcr` type support, `scheme/acpi` context switch, `gtdt`)
|
|
||||||
- **Userspace acpid**: 24 TODOs (`acpi.rs`: 10, `dmar/`: 9, `main.rs`: 3, `scheme.rs`: 1, `aml_physmem.rs`: 1)
|
|
||||||
- **Total**: 40 TODOs
|
|
||||||
|
|
||||||
### 2.6 Alignment with ACPI-IMPROVEMENT-PLAN.md

## 3. IRQ / PCI Reassessment
|
|
||||||
|
|
||||||
### 3.1 Architecture
|
|
||||||
|
|
||||||
```
|
|
||||||
PCI Device → MSI/MSI-X message (address 0xFEE0_0xxx + data)
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
APIC (local or I/O) → Vector delivery to target CPU
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Kernel IDT → generic_irq handler (vec 32–255)
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
scheme/irq.rs → irq_trigger(irq, token)
|
|
||||||
├── iommu_validate_msi_irq(irq) ← STUB: returns true unconditionally
|
|
||||||
├── increment COUNTS[irq]
|
|
||||||
├── walk HANDLES for matching fd
|
|
||||||
└── trigger EVENT_READ
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Userspace driver → IrqHandle::wait() returns with count
|
|
||||||
```
|
|
||||||
|
|
||||||
### 3.2 What Is Working
|
|
||||||
|
|
||||||
| Component | File | Evidence |
|
|
||||||

### 3.3 Critical Stubs
|
|
||||||
|
|
||||||
| Location | Line | Issue | Severity |
|
|
||||||
|----------|------|-------|----------|
|
|
||||||
| `kernel/src/scheme/irq.rs` | 231 | `iommu_validate_msi_irq(_irq) -> bool { true }` — **zero IOMMU validation** | 🔴 CRITICAL |
|
|
||||||
| `kernel/src/arch/x86_shared/device/local_apic.rs` | 81 | `//self.setup_timer();` — **APIC timer disabled** | 🟠 HIGH |
|
|
||||||
| `kernel/src/arch/x86_shared/interrupt/irq.rs` | 307 | `println!("Local apic timer interrupt");` — debug artifact | 🟡 MEDIUM |
|
|
||||||
| `kernel/src/arch/x86_shared/device/ioapic.rs` | 329–331 | `.unwrap()` on cpuid — panic risk | 🟡 MEDIUM |
|
|
||||||
| `drivers/pcid/src/driver_interface/irq_helpers.rs` | — | "FIXME for cpu_id >255 need IOMMU IRQ remapping" | 🟠 HIGH |
|
|
||||||
| `drivers/pcid/src/driver_interface/irq_helpers.rs` | — | "FIXME allow allocating multiple interrupt vectors" | 🟠 HIGH |
|
|
||||||
|
|
||||||
### 3.4 Patch-Backed Code
|
|
||||||
|
|
||||||
The following kernel code does **not exist in upstream** — it is entirely Red Bear patches:
|
|
||||||
|
|
||||||
- `msi.rs` (+183 lines) — added by `P8-msi.patch` (281 lines, 12 hunks)
|
|
||||||
- `vector.rs` (+53 lines) — added by `P8-msi.patch`
|
|
||||||
- IOAPIC affinity — `P9-ioapic-irq-affinity.patch`
|
|
||||||
- IRQ affinity wiring — `P10-irq-affinity-wiring.patch`
|
|
||||||
- x2APIC ICR fix — `P20-x2apic-icr-mode-fix.patch`
|
|
||||||
- x2APIC SMP fix — `P21-x2apic-smp-fix.patch`
|
|
||||||
- x2APIC MADT fallback — `P22-x2apic-madt-fallback.patch`
|
|
||||||
|
|
||||||
**Risk**: If upstream kernel rebases, these patches must be rebased. The MSI/MSI-X subsystem is entirely patch-dependent.
|
|
||||||
|
|
||||||
### 3.5 Alignment with IRQ Enhancement Plan
|
|
||||||
|
|
||||||
The plan reports all 6 Waves as **✅ Complete**. Code inspection confirms the Waves addressed panic hardening and code quality. However, **6 priority areas remain entirely open** and the plan does not flag:
|
|
||||||
|
|
||||||
- `iommu_validate_msi_irq()` stub (CRITICAL — not mentioned)
|
|
||||||
- APIC timer disabled (not mentioned)
|
|
||||||
- Single-vector-per-device limit (mentioned as FIXME but not prioritized)
|
|
||||||

|
||||||
## 4. Enumeration / Driver Binding Reassessment
|
|
||||||
|
|
||||||
### 4.1 Current Flow
|
|
||||||
|
|
||||||
```
|
|
||||||
pcid enumerates PCI bus → /scheme/pci/{segment}--{bus}--{device}.{function}/
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
driver-manager (or pcid-spawner legacy) reads /scheme/pci/
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
For each device: query config space (vendor, device, class, subclass)
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Match against driver config (PCI class/vendor/device ID lookup)
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Spawn driver daemon with PCID_CLIENT_CHANNEL env var
|
|
||||||
│
|
|
||||||
▼
|
|
||||||
Driver opens /scheme/pci/{addr}/config and /scheme/irq/{irq}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 4.2 Limitations
|
|
||||||
|
|
||||||
1. **No ACPI _HID/_CID matching**: Non-PCI devices (ACPI-enumerated GPIO, I2C, etc.) are not bound through the driver-manager.
|
|
||||||
2. **No modalias generation**: Drivers are matched by simple class-code or vendor/device ID — no automatic alias generation from PCI class/subclass/prog-if.
|
|
||||||
3. **LegacyBackend is a stub**: `hwd/backend/legacy.rs:13` — "TODO: handle driver spawning from legacy backend" — any non-ACPI, non-DTB platform gets no hardware discovery.
|
|
||||||
4. **Initfs transitional**: `hwd` and `acpid` live on initfs boot path, not under stable rootfs service contract.
|
|
||||||
|
|
||||||
### 4.3 Alignment with Boot-Process-Hardware-Detection-Plan.md
|
|
||||||
|
|
||||||
| Wave | Plan Status | Code Reality |
|
|
||||||
|------|-------------|--------------|
|
|
||||||
| W0 Boot stage definitions | ✅ Done | Config-only |
|
|
||||||
| W1 ACPI bus in driver-manager | ✅ Done | `AcpiBus` exists |
|
|
||||||
| W2 Resource parser (_CRS, _PRT) | ✅ Done | Parsed |
|
|
||||||
| W2b ACPI device binding | ✅ Done | Wired |
|
|
||||||
| W2c GPIO/I2C configs | Partial | Runtime _CRS evaluation **not started** |
|
|
||||||
| W3 Service rewiring | ✅ Done | Stage targets wired |
|
|
||||||
| W4 Dead /etc/pcid.d/ removal | ✅ Done | Removed |
|
|
||||||
| W5 Deferred probing | ✅ Already had | Scheme-aware |
|
|
||||||
| W6 USB topology enumeration | **Not started** | Depends on xHCI IRQ stability |

## 5. Driver Infrastructure Reassessment
|
|
||||||
|
|
||||||
### 5.1 redox-driver-sys
|
|
||||||
|
|
||||||
**Status: ✅ Production quality, zero stubs, zero TODOs**
|
|
||||||
|
|
||||||
- **Schemes**: memory (physical mapping, cache type control), irq (registration, wait, affinity), pci (enumeration, config space, BARs, MSI-X)
|
|
||||||
- **Quirks**: 3-layer (compiled-in 11 entries + TOML runtime + DMI/SMBIOS 8 rules), 22 PCI flags, 21 USB flags
|
|
||||||
- **MSI-X**: Full `MsixTable` with validated x86 message programming, vector allocation, CPU round-robin
|
|
||||||
- **DMA**: `DmaBuffer` (phys-contiguous), `IommuDmaAllocator` (MAP/UNMAP protocol)
|
|
||||||
- **Tests**: 30+ unit tests in `pci.rs`
|
|
||||||
|
|
||||||
### 5.2 linux-kpi
|
|
||||||
|
|
||||||
**Status: ✅ Structurally complete for GPU + Wi-Fi, 119 tests passing, zero stubs**
|
|
||||||
|
|
||||||
- **17 Rust modules**, **32 C headers**
|
|
||||||
- **Full implementations**: pci (777 lines), net (809), wireless (1002), mac80211 (959), irq (228), firmware (277), drm_shim (374)
|
|
||||||
- **No `todo!()`/`unimplemented!()`** in any audited module
|
|
||||||
- **C header coverage**: pci.h, skbuff.h, interrupt.h, firmware.h, netdevice.h, ieee80211.h, nl80211.h, cfg80211.h, mac80211.h, drm*.h, atomic.h, spinlock.h, mutex.h, workqueue.h, timer.h, wait.h, list.h, slab.h, mm.h, io.h, types.h, errno.h, compiler.h, export.h, printk.h, module.h, refcount.h, jiffies.h, kernel.h, idr.h, bug.h
|
|
||||||
|
|
||||||
### 5.3 firmware-loader
|
|
||||||
|
|
||||||
**Status: ✅ Production quality**
|
|
||||||
|
|
||||||
- `scheme:firmware` daemon with `SchemeSync` impl
|
|
||||||
- MANIFEST generation (BLAKE3), `--probe`, `--request-nowait`
|
|
||||||
- Path traversal prevention, 64MB blob cap, cache with source signature validation
|
|
||||||
- AMD GPU: 17 firmware keys expected; Intel: per-generation DMC firmware
|
|
||||||
|
|
||||||
### 5.4 GPU Drivers
|
|
||||||
|
|
||||||
| Driver | Status | Key Gap |
|
|
||||||
|--------|--------|---------|
|
|
||||||
| redox-drm (AMD) | 🟡 Compiles, 616 lines | `synthetic_edid()` fallback — no real DDC/I²C |
|
|
||||||
| redox-drm (Intel) | 🟡 Compiles, 693 lines | `synthetic_edid()` fallback — no real DDC/I²C |
|
|
||||||
| redox-drm (VirtIO) | 🟡 Compiles | `synthetic_edid()` fallback |
|
|
||||||
| amdgpu (C port) | 🟡 Compiles, ~1487 lines | Hardcoded 4 connector descriptors, no real HPD |
|
|
||||||
|
|
||||||
**All three GPU drivers use `synthetic_edid()`** at `redox-drm/src/kms/connector.rs:35` — a hardcoded 128-byte EDID 1.4 block for 1920×1080@60Hz. This blocks real display detection on bare metal.
|
|
||||||
|
|
||||||
### 5.5 Wi-Fi
|
|
||||||
|
|
||||||
**Status: 🟡 Compiles + host-tested, zero hardware validation**
|
|
||||||
|
|
||||||
- `redbear-iwlwifi`: C transport layer (~2450 lines) + Rust daemon (~1550 lines)
|
|
||||||
- 8 host tests pass
|
|
||||||
- Commands time out without real firmware — by design
|
|
||||||
- No Intel Wi-Fi device ever exercised
|
|
||||||
|
|
||||||
### 5.6 USB
|
|
||||||
|
|
||||||
**Status: 🟡 xhcid builds + QEMU proofs pass, bare-metal incomplete**
|
|
||||||
|
|
||||||
- xhcid: Red Bear patched, QEMU IRQ delivery proven
|
|
||||||
- usbscsid: USB mass storage with inline quirks (214 storage quirks)
|
|
||||||
- usbhubd: Hub port management
|
|
||||||
- **Gap**: No EHCI, UHCI, or OHCI drivers — legacy USB keyboards on companion controllers are unreachable on bare metal
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 6. Cross-Cutting Critical Gaps (Updated Priority)
|
|
||||||
|
|
||||||
### Gap 1 — IOMMU MSI Validation (CRITICAL)
|
|
||||||
**File**: `kernel/src/scheme/irq.rs:231`
|
|
||||||
```rust
|
|
||||||
fn iommu_validate_msi_irq(_irq: u8) -> bool {
|
|
||||||
true
|
|
||||||
}
|
|
||||||
```
|
|
||||||
Every MSI/MSI-X interrupt bypasses IOMMU remapping validation. This is a security and correctness gap. The hook exists but has zero logic.
|
|
||||||
|
|
||||||
**Root cause**: IOMMU daemon (`iommu`) provides AMD-Vi runtime but no Intel VT-d. The validation function needs remapping table data from the IOMMU daemon, or validation must move to userspace via a scheme call.
|
|
||||||
|
|
||||||
**Action**: Implement real validation against IOMMU remapping tables, or explicitly document that MSI/MSI-X without IOMMU is only safe on trusted buses.
|
|
||||||
|
|
||||||
### Gap 2 — AML Physical Memory Stubs (CRITICAL)
|
|
||||||
**Files**: `acpid/src/aml_physmem.rs:195`, `:274`
|
|
||||||
- `read_phys_or_fault()` returns `T::zero()` on failure — fabricates data
|
|
||||||
- `map_physical_region()` falls back to zero page — silent data loss
|
|
||||||
|
|
||||||
**Impact**: Any AML method accessing a physical memory region that fails to map will see fabricated zeroes. This can cause:
|
|
||||||
- Incorrect battery/thermal readings
|
|
||||||
- Silent EC communication failures
|
|
||||||
- Wrong power state transitions
|
|
||||||
|
|
||||||
**Action**: Propagate `Result<T>` errors to AML evaluation callers instead of fabricating values.
|
|
||||||
|
|
||||||
### Gap 3 — Kernel Sleep Path PCI Stubs (CRITICAL)
|
|
||||||
**File**: `kernel/src/arch/x86_shared/sleep.rs:257–276`
|
|
||||||
- `read_pci_u8/u16/u32` always return 0
|
|
||||||
- `write_pci_*` are no-ops
|
|
||||||
|
|
||||||
**Impact**: Any AML code using PCI config space access in the kernel S3/S5 sleep path gets fabricated values. This is only safe if the sleep path guarantees no PCI-dependent AML methods are evaluated.
|
|
||||||
|
|
||||||
**Action**: Either wire real PCI config space access in the kernel sleep path, or explicitly scope the kernel AML interpreter to exclude PCI-dependent methods.
|
|
||||||
|
|
||||||
### Gap 4 — APIC Timer Disabled (HIGH)
|
|
||||||
**File**: `kernel/src/arch/x86_shared/device/local_apic.rs:81`
|
|
||||||
- `setup_timer()` commented out
|
|
||||||
- System uses PIT fallback for all timer interrupts
|
|
||||||
|
|
||||||
**Impact**: No per-CPU timer interrupts (all CPUs share PIT on BSP), no TSC deadline mode for modern CPUs, potential timer skew on SMP.
|
|
||||||
|
|
||||||
**Action**: Re-enable APIC timer with calibration against PIT or TSC. Required for per-CPU timer distribution.
|
|
||||||
|
|
||||||
### Gap 5 — Synthetic EDID in All GPU Drivers (HIGH)
|
|
||||||
**File**: `redox-drm/src/kms/connector.rs:35`
|
|
||||||
- All three drivers (AMD, Intel, VirtIO) use hardcoded EDID
|
|
||||||
- No real DDC/I²C display detection
|
|
||||||
|
|
||||||
**Impact**: Display will not work on bare metal with non-1080p panels, multi-monitor setups, or displays with non-standard timings.
|
|
||||||
|
|
||||||
**Action**: Implement I²C-over-DDC EDID retrieval in `redox-drm`, or at minimum implement a real connector detection path that queries HPD + DDC before falling back to synthetic.
|
|
||||||
|
|
||||||
### Gap 6 — Dual AML Interpreters (HIGH)
|
|
||||||
**Files**: `kernel/src/arch/x86_shared/sleep.rs` (acpi_ext crate) + `acpid/src/acpi.rs` (acpi crate)
|
|
||||||
- Two independent parsers for the same DSDT/SSDT
|
|
||||||
- Different handler implementations (kernel has PCI stubs, userspace has physmem stubs)
|
|
||||||
- Bug fixes in one do not affect the other
|
|
||||||
|
|
||||||
**Impact**: Maintenance risk, correctness divergence, two surfaces for AML security issues.
|
|
||||||
|
|
||||||
**Action**: Converge on a single canonical interpreter. Recommendation: userspace (acpid) since all drivers are userspace per project model. Kernel sleep path should delegate to userspace or use a shared, read-only AML namespace.
|
|
||||||
|
|
||||||
### Gap 7 — No EHCI/UHCI/OHCI Drivers (HIGH)
|
|
||||||
**Impact**: Legacy USB keyboards on companion controller paths unreachable on bare metal. Only xHCI-native USB devices work.
|
|
||||||
|
|
||||||
**Action**: Implement EHCI driver (highest priority — covers most USB 2.0 controllers with xHCI companion). UHCI/OHCI are lower priority (very old hardware).
|
|
||||||
|
|
||||||
### Gap 8 — No C-State Kernel Backend (HIGH)
|
|
||||||
**Impact**: CPUs run at full frequency constantly on bare metal. Thermal throttling only.
|
|
||||||
|
|
||||||
**Action**: Implement `cpuidle`/`cpufreq` kernel backend using MWAIT or HLT. Discovery exists in acpid (`cstate.rs`) but kernel has no idle driver.
|
|
||||||
|
|
||||||
### Gap 9 — DMAR Orphaned (MEDIUM)
|
|
||||||
**File**: `acpid/src/acpi.rs:545`
|
|
||||||
- 533 lines of Intel VT-d parsing code
|
|
||||||
- `Dmar::init()` commented out — "hangs on real hardware"
|
|
||||||
|
|
||||||
**Action**: Either fix the hang and assign a runtime owner (iommu daemon), or remove the orphaned code until ready.
|
|
||||||
|
|
||||||
### Gap 10 — >256 CPU MSI Remapping (MEDIUM)
|
|
||||||
**File**: `drivers/pcid/src/driver_interface/irq_helpers.rs`
|
|
||||||
- 8-bit APIC destination field limits MSI target selection
|
|
||||||
- IOMMU interrupt remapping required for >256 CPUs
|
|
||||||
|
|
||||||
**Action**: Gated on IOMMU maturity (Gap 1).
|
|
||||||

|
|
||||||
## 7. Updated Execution Plan
|
|
||||||
|
|
||||||
### Phase 1: Critical Stub Removal (2–3 weeks)
|
|
||||||
**Goal**: Remove all CRITICAL-severity stubs before any hardware validation.
|
|
||||||
|
|
||||||
| # | Task | File | Effort | Owner |
|
|
||||||
|---|------|------|--------|-------|
|
|
||||||
| 1.1 | Fix `read_phys_or_fault()` zero-return | `acpid/src/aml_physmem.rs:195` | 2 days | — |
|
|
||||||
| 1.2 | Fix `map_physical_region()` zero-page fallback | `acpid/src/aml_physmem.rs:274` | 2 days | — |
|
|
||||||
| 1.3 | Fix kernel sleep path PCI read stubs | `kernel/src/arch/x86_shared/sleep.rs:257–276` | 3 days | — |
|
|
||||||
| 1.4 | Document kernel PCI stub scope | `sleep.rs` | 1 day | — |
|
|
||||||
| 1.5 | Remove `println!` debug artifact | `kernel/src/arch/x86_shared/interrupt/irq.rs:307` | 1 hour | — |
|
|
||||||
|
|
||||||
**Gate**: All CRITICAL stubs removed + `cargo check` clean on affected modules.
|
|
||||||
|
|
||||||
### Phase 2: IOMMU + MSI Validation (3–4 weeks)
|
|
||||||
**Goal**: Make MSI/MSI-X delivery trustworthy.
|
|
||||||
|
|
||||||
| # | Task | File | Effort | Owner |
|
|
||||||
|---|------|------|--------|-------|
|
|
||||||
| 2.1 | Implement `iommu_validate_msi_irq()` real logic | `kernel/src/scheme/irq.rs:231` | 1 week | — |
|
|
||||||
| 2.2 | Wire IOMMU remapping table read into kernel | `iommu` daemon ↔ `scheme/irq` | 1 week | — |
|
|
||||||
| 2.3 | QEMU validation: MSI-X with IOMMU enabled | `test-msix-qemu.sh` | 2 days | — |
|
|
||||||
| 2.4 | Fix or remove orphaned DMAR code | `acpid/src/acpi.rs:545` | 2 days | — |
|
|
||||||
|
|
||||||
**Gate**: `test-msix-qemu.sh` passes with IOMMU enabled + no `iommu_validate_msi_irq()` stub.
|
|
||||||
|
|
||||||
### Phase 3: Timer + CPU Power (2–3 weeks)
|
|
||||||
**Goal**: Enable per-CPU timers and basic CPU idle.
|
|
||||||
|
|
||||||
| # | Task | File | Effort | Owner |
|
|
||||||
|---|------|------|--------|-------|
|
|
||||||
| 3.1 | Re-enable APIC timer with calibration | `kernel/src/arch/x86_shared/device/local_apic.rs:81` | 3 days | — |
|
|
||||||
| 3.2 | Implement kernel cpuidle backend (MWAIT/HLT) | New file: `kernel/src/arch/x86_shared/cpuidle.rs` | 1 week | — |
|
|
||||||
| 3.3 | Wire acpid C-state discovery to kernel idle | `acpid/src/cstate.rs` → kernel | 3 days | — |
|

|
||||||
| Plan | Claimed Timeline | Reality |
|
|
||||||
|------|-----------------|---------|
|
|
||||||
| COMPREHENSIVE P1 (bare-metal hardening) | 6–8 weeks | Understated — no critical stub removal phase |
|
|
||||||
| COMPREHENSIVE P2 (USB) | 4–6 weeks | Realistic for EHCI only |
|
|
||||||
| COMPREHENSIVE P3 (IRQ/IOMMU) | 4–6 weeks | Realistic if focused on Gap 1 only |
|
|
||||||
| IRQ plan Waves 1–6 | "Complete" | Code quality complete, validation not started |
|
|
||||||
| ACPI plan Waves 0–7 | W0–W4 partial, W5–W7 open | Accurate, but two critical stubs not flagged |
|
|
||||||
| SMP plan bottlenecks | 11–18 days | Realistic for B1–B2 only |

## 9. Risk Register
|
|
||||||
|
|
||||||
| # | Risk | Likelihood | Impact | Mitigation |
|
|
||||||
|---|------|-----------|--------|------------|
|
|
||||||
| R1 | `aml_physmem` stub fix reveals deeper AML memory access issues | Medium | High | Fix with comprehensive error propagation; add fallback to kernel scheme for problematic regions |
|
|
||||||
| R2 | IOMMU validation implementation requires kernel ABI change | Medium | High | Prototype in userspace first via `scheme:iommu` call; only promote to kernel if performance requires it |
|
|
||||||
| R3 | APIC timer calibration fails on specific CPU models | Medium | Medium | Keep PIT fallback path; detect calibration failure and degrade gracefully |
|
|
||||||
| R4 | DDC/I²C implementation requires GPIO/I2C subsystem not yet built | High | High | Scope Phase 4 to "query EDID via ACPI _DDC method first, then direct I²C"; fallback to synthetic still acceptable for initial bring-up |
|
|
||||||
| R5 | EHCI driver requires IRQ/MSI-X fixes first | Medium | Medium | Phase 5 starts after Phase 2 gate; use legacy IRQ for EHCI if MSI-X not ready |
|
|
||||||
| R6 | AML convergence breaks S3 sleep path | Medium | High | Keep kernel sleep.rs as fallback during transition; remove only after S3 validated via userspace path |
|
|
||||||
| R7 | No bare-metal hardware available for validation | Medium | Critical | Prioritize QEMU proofs for all phases; document "QEMU-validated" vs "bare-metal-validated" per subsystem |

## 12. Document Authority
|
|
||||||
|
|
||||||
This document is a **cross-cutting reassessment** that references but does not replace the canonical subsystem plans:
|
|
||||||
|
|
||||||
- For ACPI wave-level execution detail, see `ACPI-IMPROVEMENT-PLAN.md`
|
|
||||||
- For IRQ/PCI wave-level execution detail, see `IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md`
|
|
||||||
- For boot detection wave detail, see `BOOT-PROCESS-HARDWARE-DETECTION-PLAN.md`
|
|
||||||
- For SMP bottleneck detail, see `SMP-SCHEDULER-IMPROVEMENT-PLAN.md`
|
|
||||||
- For desktop path blockers, see `CONSOLE-TO-KDE-DESKTOP-PLAN.md`
|
|
||||||
|
|
||||||
**When this document conflicts with a canonical subsystem plan**, the **canonical plan** wins on subsystem-specific details, and this document wins on cross-cutting prioritization and inter-subsystem dependencies.
|
|
||||||
|
|
||||||
**This document should be updated** after each phase gate is reached, or when new critical stubs are discovered.

# Red Bear OS SMP Boot & Scheduler Hardening Plan
|
||||||
|
|
||||||
|
**Version**: 1.0 — 2026-05-16
|
||||||
|
**Status**: Active
|
||||||
|
**Canonical**: This document supersedes `SMP-SCHEDULER-IMPROVEMENT-PLAN.md` for forward work.
|
||||||
|
**Scope**: Kernel SMP, AP startup, x2APIC, per-CPU data, TLB shootdowns, IRQ routing, scheduler, userspace boot, daemon robustness.
|
||||||
|
|
||||||
|
## Assessment Summary
|
||||||
|
|
||||||
|
Comprehensive assessment of kernel SMP infrastructure (20 source files), userspace boot process (10 source files), and modern Intel/AMD MP specifications. Cross-referenced with Linux `smpboot.c`, Zircon `lk_main`, and seL4 multicore boot.
|
||||||
|
|
||||||
|
**Total issues found: 38 kernel + 16 userspace = 54 issues**
|
||||||
|
- Critical: 6 kernel + 3 userspace = 9
|
||||||
|
- High: 7 kernel + 4 userspace = 11
|
||||||
|
- Medium: 10 kernel + 5 userspace = 15
|
||||||
|
- Low: 15 kernel + 4 userspace = 19

|
|
||||||
|
| # | Issue | File | Root Cause |
|
||||||
|
|---|-------|------|------------|
|
||||||
|
| K1 | AP startup LogicalCpuId race | `madt/arch/x86.rs:153,244,276,365` | Two APs `CPU_COUNT.load(Relaxed)` → same ID → both `fetch_add(1)` |
|
||||||
|
| K2 | AP_READY dual-mechanism sync race | `madt/arch/x86.rs:174-225` | Trampoline u64 `ap_ready.write(0)` + static `AtomicBool AP_READY` — inconsistent ordering, UB on cast |
|
||||||
|
| K3 | TLB shootdown range race | `percpu.rs:134-137` | Concurrent shootdowns overwrite `tlb_flush_start`/`tlb_flush_count` between flag set and IPI |
|
||||||
|
| K4 | MCS lock missing memory fences | `sync/mcs.rs:74-101` | No Release after `next.store()`, no Acquire before `locked.load()` |
|
||||||
|
| K5 | Unbounded priority inversion chain | `sync/mcs.rs:126-145` | PI donation goes one level only; transitive chains unbounded |
|
||||||
|
| K6 | Scheduler context switch flag not cleared on panic | `switch.rs:164,298` | `in_context_switch` stays true → permanent CPU lockup |

## Reference: Modern Hardware Requirements
|
||||||
|
|
||||||
|
Sources: Intel 64/IA-32 SDM Vol 3A Ch 8, AMD64 APM Vol 2 Ch 7, ACPI 6.5, Intel x2APIC spec, Linux smpboot.c, Zircon lk_main, seL4 multicore boot.
|
||||||
|
|
||||||
|
### AP Startup Timing (Intel SDM)
|
||||||
|
- INIT deassert → SIPI: **10ms** (modern CPUs: can be shorter)
|
||||||
|
- SIPI #1 → SIPI #2: **10-300µs** (modern: 10µs, legacy: 300µs)
|
||||||
|
- AP response timeout: **10 seconds** (Linux)
|
||||||
|
- ESR check: Clear before each SIPI, read after to verify acceptance
|
||||||
|
|
||||||
|
### AP Startup Timing (AMD)
|
||||||
|
- Similar INIT/SIPI sequence
|
||||||
|
- CPUID leaf `0x8000001E` for topology (ext_apic_id, core_id, node_id)
|
||||||
|
- CPUID leaf `0x1F` preferred for V2 extended topology (Intel + newer AMD)
|
||||||
|
- APIC ID may exceed 255 → x2APIC mandatory
|
||||||
|
|
||||||
|
### x2APIC Requirements
|
||||||
|
- **Mandatory**: CPU count > 255 (8-bit APIC ID exhausted)
|
||||||
|
- **Detection**: CPUID.01H:ECX[bit 21]
|
||||||
|
- **ICR**: Single 64-bit MSR write (vs two 32-bit MMIO writes)
|
||||||
|
- **No delivery status bit**: Hardware guarantees delivery
|
||||||
|
- **Self-IPI**: Dedicated MSR 0x83F (fastest single-IPI path)
|
||||||
|
|
||||||
|
### ACPI MADT Entry Types (ACPI 6.5)
|
||||||
|
- Type 0: Processor Local APIC (legacy 8-bit)
|
||||||
|
- Type 1: I/O APIC
|
||||||
|
- Type 2: Interrupt Source Override
|
||||||
|
- Type 4: Local APIC NMI
|
||||||
|
- Type 5: Local APIC Address Override
|
||||||
|
- **Type 9: Processor Local x2APIC** (32-bit ID, required for modern hardware)
|
||||||
|
- **Type 10: Local x2APIC NMI**
|
||||||
|
- Type 20: Multi-Processor Wakeup Structure (ACPI 6.4+)
|
||||||
|
|
||||||
|
### Common Firmware Bugs
|
||||||
|
1. Duplicate APIC IDs in MADT
|
||||||
|
2. Incorrect enabled flags
|
||||||
|
3. Missing entries (CPU exists but no MADT entry)
|
||||||
|
4. MADT UID / DSDT _UID mismatch
|
||||||
|
5. SLIT diagonal != 10 (Linux validates and rejects)
|
||||||
|
6. SRAT-SLIT inconsistency
|
||||||
|
|
||||||
|
### Linux Best Practices
|
||||||
|
- Parallel AP bringup (all APs kicked simultaneously) — reduces boot 500ms→100ms on 96-core
|
||||||
|
- Adaptive SIPI timing: `init_udelay=0` → 10µs for modern CPUs
|
||||||
|
- 10-second timeout with `schedule()` yield loop
|
||||||
|
- ESR check after each SIPI, retry up to 2×
|
||||||
|
- `cpu_callout_mask` / `cpu_callin_mask` handshake
|
||||||
|
|
||||||
|
### Zircon Best Practices
|
||||||
|
- Phased initialization: BSP → topology → AP release → AP init → sync
|
||||||
|
- 30-second startup timeout, OOPS (not panic) on timeout
|
||||||
|
- Idle threads pre-allocated before releasing APs
|
||||||
|
- Init levels coordinate initialization order
|
||||||
|
|
||||||
|
### seL4 Best Practices
|
||||||
|
- Single atomic write releases all APs simultaneously
|
||||||
|
- Explicit cache maintenance for ARM32
|
||||||
|
- Big kernel lock for simplicity (not scalable)
|
||||||
|
- BOOT_BSS section for boot-time variables

## Improvement Plan — Patch Series
|
||||||
|
|
||||||
|
### Priority 0: Fix All Discovered Issues (P15)
|
||||||
|
|
||||||
|
#### P15-1: AP Startup LogicalCpuId Race Fix (Critical K1)
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: Replace `CPU_COUNT.load(Relaxed)` + `LogicalCpuId::new(next_cpu)` + `CPU_COUNT.fetch_add(1)` with single `let cpu_id = LogicalCpuId::new(CPU_COUNT.fetch_add(1, SeqCst))`. Remove separate load. Move all pre-startup setup (PercpuBlock init, NUMA node set) to between allocation and `fetch_add`.
|
||||||
|
**Risk**: Low. Standard atomic fix.
|
||||||
|
**Verification**: Boot with 4+ CPUs, verify all get unique IDs.
|
||||||
|
|
||||||
|
#### P15-2: AP_READY Sync Consolidation (Critical K2)
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: Replace dual mechanism with single `AtomicU8` at TRAMPOLINE+8. AP writes 1 when ready. BSP polls with SeqCst. Add `fence(SeqCst)` before/after writing trampoline args to ensure AP sees them.
|
||||||
|
**Risk**: Medium. Changes trampoline protocol.
|
||||||
|
**Verification**: Boot test on QEMU, verify all APs start correctly.
|
||||||
|
|
||||||
|
#### P15-3: TLB Shootdown Range Race Fix (Critical K3)
|
||||||
|
**Files**: `src/percpu.rs`
|
||||||
|
**Change**: Pack range into single `AtomicU64` (bits [63:32] = start page, bits [31:0] = count). Single atomic `swap` sets flag + range atomically. Handler unpacks with single `load`.
|
||||||
|
**Risk**: Medium. Affects all TLB shootdowns.
|
||||||
|
**Verification**: Multi-core stress test with frequent mmap/munmap.
|
||||||
|
|
||||||
|
#### P15-4: MCS Lock Memory Ordering (Critical K4)
|
||||||
|
**Files**: `src/sync/mcs.rs`
|
||||||
|
**Change**: Add `fence(Release)` after `next.store(new_node, Relaxed)` at line 55. Add `fence(Acquire)` before `locked.load(Relaxed)` at line 59. Change PI donation store to `Release`.
|
||||||
|
**Risk**: Low. Standard lock ordering fix.
|
||||||
|
**Verification**: Multi-threaded contention test.
|
||||||
|
|
||||||
|
#### P15-5: NUMA Node Before CPU Visible (High K8)
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: Move `record_apic_mapping()` and `percpu.numa_node.set()` BEFORE `CPU_COUNT.fetch_add()`. Add `fence(SeqCst)` between them so scheduler sees NUMA data.
|
||||||
|
**Risk**: Low. Reordering of operations.
|
||||||
|
**Verification**: Boot with QEMU SRAT, verify NUMA nodes set before scheduler sees CPUs.
|
||||||
|
|
||||||
|
#### P15-6: Init Dependency Deadlock Fix (Critical U1)
|
||||||
|
**Files**: `config/redbear-mini.toml`, `config/redbear-full.toml`
|
||||||
|
**Change**: Add `default_dependencies = false` to `00_intel-gpiod.service`, `00_i2c-dw-acpi.service`, `00_i2c-gpio-expanderd.service`, `00_i2c-hidd.service`, `ucsid.service`. Add explicit `requires_weak` for actual dependencies only.
|
||||||
|
**Risk**: Low. Config-only change.
|
||||||
|
**Verification**: Boot redbear-mini, verify all services start without deadlock.
|
||||||
|
|
||||||
|
#### P15-7: Service Timeout Mechanism (Critical U2)
|
||||||
|
**Files**: `recipes/core/base/source/init/src/service.rs`, `recipes/core/base/source/init/src/scheduler.rs`
|
||||||
|
**Change**: Add `timeout_secs: Option<u32>` to Notify and Scheme variants. Use `set_read_timeout()` on INIT_NOTIFY pipe. On timeout, log error and mark service failed. Boot continues.
|
||||||
|
**Risk**: Medium. Changes init behavior.
|
||||||
|
**Verification**: Create a service that never notifies, verify boot continues after timeout.
|
||||||
|
|
||||||
|
#### P15-8: Dependency Cycle Detection (Critical U3)
|
||||||
|
**Files**: `recipes/core/base/source/init/src/scheduler.rs`
|
||||||
|
**Change**: Add `BTreeSet<UnitId>` visited tracking in `load_units()`. If a unit ID is already in the visiting set, log cycle error and skip.
|
||||||
|
**Risk**: Low. Defensive programming.
|
||||||
|
**Verification**: Create circular dependency in test config, verify detection.
|
||||||
|
|
||||||
|
#### P15-9: Boot Timeline /tmp/ Creation (Medium U6)
|
||||||
|
**Files**: `local/recipes/system/driver-manager/source/src/main.rs`
|
||||||
|
**Change**: Add `let _ = std::fs::create_dir_all("/tmp");` at top of `main()`, before `reset_timeline_log()`.
|
||||||
|
**Risk**: Trivial.
|
||||||
|
**Verification**: Boot, verify timeline file created.
|
||||||
|
|
||||||
|
#### P15-10: TLB Range Ordering Fix (High K10)
|
||||||
|
**Files**: `src/percpu.rs`
|
||||||
|
**Change**: Change `tlb_flush_start`/`tlb_flush_count` stores from `Relaxed` to `Release`. Change handler loads from `Relaxed` to `Acquire`.
|
||||||
|
**Risk**: Low. Ordering fix.
|
||||||
|
**Verification**: Multi-core TLB stress test.
|
||||||
|

### Priority 1: Stabilize SMP Boot (P16)
|
||||||
|
|
||||||
|
#### P16-1: Calibrated SIPI Delays (High K7)
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: Implement `udelay(us)` using TSC (calibrated during early boot). Replace spin-count delays: 10ms INIT→SIPI, 10µs SIPI→SIPI for modern CPUs.
|
||||||
|
**Reference**: Linux `wakeup_secondary_cpu_via_init()`, Intel SDM Vol 3A §8.4.
|
||||||
|
|
||||||
|
#### P16-2: AP Startup Error Status Check (Medium)
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: After each SIPI, clear and read APIC ESR. If delivery error, retry. Log failure for each CPU. Continue boot with available CPUs.
|
||||||
|
**Reference**: Linux checks `send_status` + `accept_status`.
|
||||||
|
|
||||||
|
#### P16-3: MAX_CPU_COUNT Increase (High K12)
|
||||||
|
**Files**: `src/cpu_set.rs`
|
||||||
|
**Change**: Increase `MAX_CPU_COUNT` from 128 to 256. Add boot-time warning if CPUs approach limit.
|
||||||
|
|
||||||
|
#### P16-4: AP Startup Graceful Degradation
|
||||||
|
**Files**: `src/acpi/madt/arch/x86.rs`
|
||||||
|
**Change**: If AP fails trampoline or AP_READY timeout, log warning, skip CPU, continue boot. Track `cpu_online` mask separately from `cpu_possible`.
|
||||||
|
|
||||||
|
#### P16-5: Firmware Bug Detection
|
||||||
|
**Files**: `src/acpi/madt/mod.rs`, `src/acpi/mod.rs`
|
||||||
|
**Change**: Add duplicate APIC ID detection during MADT parsing. Add SDT checksum validation (`sum all bytes == 0`). Log warnings for unknown MADT entry types. Cross-reference MADT entries with SRAT for consistency.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Priority 2: Desktop-Safe Scheduler (P17)
|
||||||
|
|
||||||
|
#### P17-1: NUMA-Aware Work Stealing (Medium K20)
|
||||||
|
**Files**: `src/context/switch.rs`
|
||||||
|
**Change**: In `select_next_context()`, prefer contexts on same NUMA node. Use `numa::topology().same_node()`. Apply penalty for cross-node stealing. Use SLIT distance matrix for weight.
|
||||||
|
|
||||||
|
#### P17-2: Transitive Priority Inheritance (Critical K5)
|
||||||
|
**Files**: `src/sync/mcs.rs`
|
||||||
|
**Change**: When donating priority to lock holder, check if holder is waiting on another MCS lock. Propagate donation transitively up to 4 levels deep (bounded). Add lock graph cycle detection.
|
||||||
|
|
||||||
|
#### P17-3: CPU Affinity (New Feature)
|
||||||
|
**Files**: `src/context/context.rs`, `src/context/switch.rs`
|
||||||
|
**Change**: Add `affinity: LogicalCpuSet` to Context. Scheduler respects mask. Default: all CPUs. Add `sched_setaffinity` syscall.
|
||||||
|
|
||||||
|
#### P17-4: Preemption Latency Bounds
|
||||||
|
**Files**: `src/context/switch.rs`
|
||||||
|
**Change**: Replace hardcoded `new_ticks >= 3` with configurable interval. Enforce `preempt_locks > 0` guard at context switch. Add preemption-safe lock wrappers.
|
||||||
|
|
||||||
|
#### P17-5: Load Balancing
|
||||||
|
**Files**: `src/context/switch.rs`
|
||||||
|
**Change**: Periodic (every 100ms) load rebalancing. Migrate tasks from CPUs with >2 runnable to idle CPUs. Use NUMA distance for cross-node decisions.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### Priority 3: Harden IPC & Scheme Servers (P18)
|
||||||
|
|
||||||
|
#### P18-1: Daemon Restart Policy (High U4)
|
||||||
|
**Files**: `recipes/core/base/source/init/src/service.rs`, `recipes/core/base/source/init/src/scheduler.rs`
|
||||||
|
**Change**: Add `restart = "on-failure" | "always" | "never"` to service config. Implement exponential backoff: 1s → 2s → 4s → 8s → 30s max. Track restart count, give up after 5 consecutive failures.
|
||||||
|
|
||||||
|
#### P18-2: Process Monitoring & Cleanup (High U5)
|
||||||
|
**Files**: `local/recipes/system/driver-manager/source/src/config.rs`
|
||||||
|
**Change**: Non-blocking `waitpid(WNOHANG)` poll in hotplug loop. On driver exit: release scheme, unbind PCI device, free IRQ. Notify init of failure.
|
||||||
|
|
||||||
|
#### P18-3: Bounded Scheme Request Queues (Medium)
|
||||||
|
**Change**: Add configurable queue depth limit to scheme daemons. When full, return EBUSY. Prevents memory exhaustion.
|
||||||
|
|
||||||
|
#### P18-4: Watchdog/Health Monitoring (High)
|
||||||
|
**Change**: Optional health-check ping in scheme protocol. Init checks critical services every 5s. On failure, restart per restart policy.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### Priority 4: Stress-Test Userspace Drivers (P19)
|
||||||
|
|
||||||
|
#### P19-1: Multi-Core Driver Stress Test
|
||||||
|
**Change**: Parallel I/O to ided/ahcid/nvmed + network e1000d + input evdevd. Verify no panics, no hangs, no data corruption over 1 hour.
|
||||||
|
|
||||||
|
#### P19-2: GPU Parallel Submission
|
||||||
|
**Change**: Multiple processes submit to virtio-gpu / redox-drm simultaneously. Verify fencing correctness, no GPU hang.
|
||||||
|
|
||||||
|
#### P19-3: USB Hotplug Under Load
|
||||||
|
**Change**: Rapid device connect/disconnect while transferring data via usbscsid. Verify cleanup and no resource leaks.
|
||||||
|
|
||||||
|
#### P19-4: Hotplug Stress Test
|
||||||
|
**Change**: QEMU virtio device hot-add/hot-remove while system under load. Verify driver-manager handles changes correctly.

# Red Bear OS Subsystem Assessment vs Linux Reference
|
||||||
|
|
||||||
|
**Date:** 2026-05-17
|
||||||
|
**Scope:** Input devices, ACPI/PCID, Intel DRM/KMS, boot process
|
||||||
|
**Reference:** Linux kernel 7.1 (local/reference/linux-7.1/)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
|
||||||
|
Red Bear OS has real, functional architectural scaffolding across all five subsystems. The critical gaps are in **hardware-facing paths that are stubbed or incomplete** — most notably Intel EDID/DDC, hardware vblank, display watermarks, AML interpreter depth, and boot dependency ordering. The single most impactful immediate fix is adding the missing `acpid` service to boot configs, which prevents ACPI-dependent drivers from enumerating correctly.
|
||||||
|
|
||||||
|
**Critical blockers for bare-metal desktop:**
|
||||||
|
1. Missing `acpid` service in redbear configs → ACPI devices never discovered
|
||||||
|
2. Intel `read_edid_block()` returns error → synthetic EDID is 112 bytes (should be 128) → no real monitor modes
|
||||||
|
3. Intel `get_vblank()` is a fake atomic counter → no real vblank for page flip synchronization
|
||||||
|
4. No display watermarks → FIFO underruns cause visible glitching
|
||||||
|
5. No boot dependency declarations → i2c-hidd/i2cd may race with acpid
|
||||||
|

## 1. Input Devices (Keyboard, Mouse, HID, I2C-HID, Touch)
|
||||||
|
|
||||||
|
### Current Implementation Inventory
|
||||||
|
|
||||||
|
| Component | Path | Quality | Key Notes |
|
||||||
|
|---|---|---|---|
|
||||||
|
| ps2d (PS/2) | `base/source/drivers/input/ps2d/` (5 files) | **Real** | Keyboard scancodes + mouse protocol. x86-only (non-x86 is `unimplemented!()`). Many TODOs, QEMU-specific hacks. No ImPS/2 scroll or trackpoint. |
|
||||||
|
| usbhidd (USB HID) | `base/source/drivers/input/usbhidd/` (2 files, 520 lines) | **Real** | Full HID report descriptor parsing, USB usage→orbclient scancode table, mouse relative+absolute, scroll, buttons. Retry with exponential backoff. Polling-based (1ms sleep loop). |
|
||||||
|
| i2c-hidd (I2C HID) | `base/source/drivers/input/i2c-hidd/` (5 files, 500+ lines) | **Real** | ACPI PNP0C50/ACPI0C50 device scan, _CRS resource parsing, _DSM HID descriptor address, I2C transfer via `/scheme/i2c/`. Probe failure quirk system with DMI matching. |

|
||||||
|
| inputd (multiplexer) | `base/source/drivers/inputd/` (3 files, 663 lines) | **Real** | Producer/consumer scheme, VT switching, keymap support (US/Dvorak/GB/AZERTY/Bepo/IT). ESTALE handoff for display driver transitions. |
|
||||||
|
| evdevd (evdev adapter) | `local/recipes/system/evdevd/` (5+ files) | **Real** | evdev scheme, device model, orbclient→evdev translation, gesture recognizer, key filter. |
|
||||||
|
| redbear-keymapd | `local/recipes/system/redbear-keymapd/` | **Real** | Keymap scheme registration and management. |
|
||||||
|
| udev-shim | `local/recipes/system/udev-shim/` | **Real** | Device node synthesis from scheme registrations, heuristic mapping. |
|
||||||
|
| I2C bus drivers | `base/source/drivers/i2c/` (5 modules) | **Real** | amd-mp2-i2cd, dw-acpi-i2cd, intel-lpss-i2cd, generic i2cd, i2c-interface library. |
|
||||||
|
| redbear-input-headers | `local/recipes/drivers/redbear-input-headers/` | **Real** | `linux/input.h`, `linux/input-event-codes.h`, `linux/uinput.h` — replaces policy-violating `linux-input-headers` from libevdev tarball. |
|
||||||
|
| libinput (WIP) | `local/recipes/libs/libinput/` | **WIP** | Port of upstream libinput with touchpad/trackpoint filtering. Not yet runtime-trusted. |
|
||||||
|

### Gaps vs Linux
|
||||||
|
|
||||||
|
| Gap | Severity | Linux Reference | Red Bear Status |
|
||||||
|
|---|---|---|---|
|
||||||
|
| intel-thc-hidd doesn't stream | **High** | `drivers/hid/intel-thc-hid/` full probe+report streaming | Main loop sleeps 5s; no HID reports |
|
||||||
|
| No multitouch/ABS_MT | **High** | `drivers/input/input-mt.c` slot tracking, pointer emulation | Not implemented |
|
||||||
|
| No libinput acceleration/gestures | **High** | libinput: velocity curves, palm detection, gesture recognition | inputd does raw keymap only |
|
||||||
|
| No PS/2 extended protocols | **Medium** | `libps2.c` ImPS/2 scroll, Explorer 5-btn, trackpoint | Basic protocol only |
|
||||||
|
| No HID quirks table | **Medium** | `hid-quirks.c` 4000+ device entries | Only probe_failure quirks |
|
||||||
|
| No input hotplug | **Medium** | udev + inotify on `/dev/input/` | Static scan at startup |
|
||||||
|
| Polling-based USB HID | **Low** | URB interrupt-driven | 1ms sleep loop (functional but power-inefficient) |
|
||||||
|
| inputd keymap incompleteness | **Low** | Full xkb/keyboard-layout support | TODO for configurable keymap, AltGr, NumLock |
|
||||||
|
|
||||||
|
### Linux I2C-HID Reference (from local/reference/linux-7.1/)
|
||||||
|
|
||||||
|
The Linux I2C-HID probe sequence is:
|
||||||
|
1. Verify IRQ exists
|
||||||
|
2. Wake/power up device (_PS0/HID_POWER_ON)
|
||||||
|
3. Read HID descriptor from controller register
|
||||||
|
4. Read report descriptor
|
||||||
|
5. Parse descriptor
|
||||||
|
6. Size buffers from actual reports
|
||||||
|
7. Register IRQ
|
||||||
|
8. `hid_add_device()`
|
||||||
|
|
||||||
|
Red Bear's i2c-hidd follows this sequence correctly. The Intel THC driver does steps 1-5 but never reaches step 7-8.

## 2. ACPI and PCID
|
||||||
|
|
||||||
|
### Current Implementation Inventory
|
||||||
|
|
||||||
|
| Component | Path | Quality | Key Notes |
|
||||||

|
||||||
|
| IOMMU daemon | `local/recipes/system/iommu/` | **Partial** | Builds, QEMU first-use proof passes. Real hardware validation pending. |
|
||||||
|
|
||||||
|
### Gaps vs Linux
|
||||||
|
|
||||||
|
| Gap | Severity | Linux Reference | Red Bear Status |
|
||||||
|
|---|---|---|---|
|
||||||
|
| AML interpreter incomplete | **Critical** | Full AML bytecode VM (While/If/Else, OperationRegion, Method locals, Notify) | Basic method calls only (_STA, _PS0, _PS3, _INI). No control flow. |
|
||||||
|

|
||||||
|
| No _OSC OS capabilities | **Medium** | `drivers/acpi/osc.c` | Not present |
|
||||||
|

|
||||||
|
| No PCI hotplug | **Low** | `drivers/pci/hotplug/` | Not present |
|
||||||
|
| No suspend/resume | **Critical** | `drivers/acpi/sleep.c` S1-S5 | sleep.rs + wakeup.asm in uncommitted changes, not wired |
|
||||||
|
| DMAR/IOMMU path commented out | **High** | `drivers/iommu/intel-iommu.c` | `acpid/src/acpi/dmar/mod.rs` has iterator bug (`len_bytes` from wrong slice), hangs on real hardware — entire DMAR path commented out |
|
||||||
|
| DMI quirk matching dead | **High** | `/sys/firmware/dmi` | `redox-driver-sys/quirks/dmi.rs` depends on `/scheme/acpi/dmi` but that source doesn't exist in the ACPI stack |
|
||||||
|
| ACPI resource parsing panics | **Medium** | N/A | `redox-driver-acpi/resource.rs` and `prt.rs` panic on unexpected ACPI resource shapes instead of returning errors |

|
| **Missing acpid service in configs** | **Critical** | N/A (config bug) | No `acpid = {}` in redbear-full.toml or redbear-device-services.toml |
|
||||||
|
|
||||||
|
### acpid Missing From Configs — Critical Bug
|
||||||
|
|
||||||
|
The boot process agent found that **no active `acpid = {}` service entry exists** in the redbear TOML configs. This means acpid may never start, which prevents ACPI symbol/resource discovery for all ACPI-dependent drivers (i2c-hidd, intel-thc-hidd, thermald, driver-manager ACPI path). This is the single highest-priority fix.

## 3. Intel DRM/KMS
|
||||||
|
|
||||||
|
### Current Implementation Inventory
|
||||||
|
|
||||||
|
| Component | Path | Quality | Key Notes |
|
||||||
|
|---|---|---|---|
|
||||||
|
| IntelDriver | `redox-drm/source/src/drivers/intel/mod.rs` (682 lines) | **Partial** | PCIe init, MMIO mapping, FORCEWAKE, connector detection, CRTC set_mode, page_flip, GEM create/mmap/close, IRQ handling. |
|
||||||
|
| IntelDisplay | `.../intel/display.rs` (404 lines) | **Partial** | Pipe detection, DDI port detection, mode setting (real HTOTAL/HBLANK/HSYNC/VTOTAL/VSYNC/PIPE_SRC register writes). **EDID: read_edid_block returns error → synthetic_edid(). DPCD: returns fake 4 bytes.** |
|
||||||
|
| IntelGtt | `.../intel/gtt.rs` | **Real** | GGTT allocation, mapping, unmapping. |
|
||||||
|
| IntelRing | `.../intel/ring.rs` (267 lines) | **Partial** | DMA ring buffer, GPU address binding. Only MI_FLUSH_DW + MI_NOOP submitted — no rendering commands. |
|
||||||
|
| DRM scheme | `redox-drm/source/src/scheme.rs` | **Real** | Full DRM/KMS ioctl surface. SETPLANE is empty, GETENCODER hardcoded. |
|
||||||
|
| KMS infrastructure | `redox-drm/source/src/kms/` (5 files) | **Real** | ConnectorInfo, ModeInfo with EDID parsing, synthetic_edid fallback. |
|
||||||
|
| Interrupt handling | `redox-drm/source/src/drivers/interrupt.rs` | **Real** | MSI/MSI-X/INTx setup, try_wait polling. |
|
||||||
|
| Linux-kpi DRM headers | `linux-kpi/source/src/c_headers/drm/` | **Minimal** | drm.h, drm_crtc.h, drm_gem.h, drm_ioctl.h — type definitions only. |
|
||||||
|
| ihdgd (legacy) | `base/source/drivers/graphics/ihdgd/` | **Old/Partial** | Separate Intel framebuffer driver. Many TODOs. Being superseded by redox-drm. |
|
||||||
|
| vesad | `base/source/drivers/graphics/vesad/` | **Legacy** | VESA framebuffer driver. No cursor support. |
|
||||||
|
| Mesa | `recipes/libs/mesa/` | **Software only** | Only swrast+virgl Gallium. No Intel iris/crocus/anv driver build. |
|
||||||
|
|
||||||
|
### Critical Bugs Found
|
||||||
|
|
||||||
|
1. **synthetic_edid() is 112 bytes, not 128** — `ModeInfo::from_edid()` requires `edid.len() >= 128` and checks for the 8-byte EDID header. The synthetic EDID is only 112 bytes so it always fails validation, forcing `default_1080p()` fallback on every Intel connector.
|
||||||
|
|
||||||
|
2. **Intel `get_vblank()` returns `AtomicU64::fetch_add(1, SeqCst)`** — This is NOT a real vblank counter. It increments on every IRQ regardless of display state. Real i915 reads the `PIPEFRAME` register (offset `0x70040 + pipe * 0x1000`) for per-pipe frame count.
|
||||||
|
|
||||||
|
### Gaps vs Linux i915
|
||||||
|
|
||||||
|
| Gap | Severity | Impact |
|
||||||
|
|---|---|---|
|
||||||
|
| EDID I2C/DDC stubbed | **Critical** | No real monitor modes — always falls back to synthetic/default |
|
||||||
|
| Vblank counter is fake | **Critical** | Page flip has no synchronization — tearing |
|
||||||
|
| Display watermarks absent | **Critical** | FIFO underruns → visible glitching on real hardware |
|
||||||
|
| No panel power sequencing | **High** | eDP panels won't turn on/off properly on laptops |
|
||||||
|
| No hardware cursor | **High** | No visible cursor in DRM mode |
|
||||||
|
| No DP AUX channel | **High** | No DisplayPort monitor support |
|
||||||
|
synthetic_edid too short (bug) | **Critical** | EDID validation always fails |
|
||||||
|
| No DMC firmware loading | **Medium** | No DC5/DC6 power state for Gen9+ |
|
||||||
|
| No HPD pulse detection | **Medium** | Monitor hotplug is crude |
|
||||||
|
| No render commands | **Medium** | Ring only does flush — no 2D/3D acceleration |
|
||||||
|
| No GGTT PTE invalidation | **Medium** | Stale TLB entries after GGTT updates |
|
||||||
|
| Mesa has no Intel driver | **High** | No hardware-accelerated OpenGL/Vulkan |

## 4. Boot Process
|
||||||
|
|
||||||
|
### Boot Sequence (as configured)
|
||||||
|
|
||||||
|
```
|
||||||
|
UEFI bootloader
|
||||||
|
→ kernel (startup, ACPI, scheme registration)
|
||||||
|
→ init (PID 1)
|
||||||
|
→ logd
|
||||||
|
→ scheme registration (memory, irq, event, pipe, debug, etc.)
|
||||||
|
→ numbered services from init.d/:
|
||||||
|
00_* : base daemons (ipcd, ptyd, randd)
|
||||||
|
02_* : driver-manager (or legacy pcid-spawner)
|
||||||
|
04_* : device drivers
|
||||||
|
06_* : D-Bus, sessiond, seatd
|
||||||
|
08_* : console/greeter
|
||||||
|
```
|
||||||
|
|
||||||
|
### Dependency Analysis
|
||||||
|
|
||||||
|
The `init` system supports `requires_weak` for service dependencies, but **most services don't declare dependencies**. The boot agent found:
|
||||||
|
|
||||||
|
- **`requires_weak`** means "if the dependency exists, wait for it; if not, proceed anyway." This is good for optional services but inadequate for strict ordering.
|
||||||
|
- **No explicit `acpid = {}` service** in redbear-full.toml or redbear-device-services.toml — ACPI-dependent drivers may never discover their devices.
|
||||||
|
- **`driver-manager`** retries deferred probes, but missing schemes (especially `acpi`) can leave drivers permanently skipped.
|
||||||
|
- **Greeter/session path works only** if dbus, seatd, redox-drm, and authd are all present. `redbear-greeterd` waits for Wayland socket, not a stronger compositor readiness signal.
|
||||||
|
|
||||||
|
### Gaps
|
||||||
|
|
||||||
|
| Gap | Severity | Notes |
|
||||||
|
|---|---|---|
|
||||||
|
| **Missing acpid service in configs** | **Critical** | No ACPI symbol discovery for i2c-hidd, thermald, driver-manager ACPI path |
|
||||||
|
| No dependency declarations | **High** | Services use number-based ordering only |
|
||||||
|
| No service readiness signaling | **High** | No sd_notify equivalent; init doesn't gate on daemon.ready() |
|
||||||
|
| No filesystem check | **Medium** | No fsck on boot; dirty filesystem mounts anyway |
|
||||||
|
| initfs→rootfs transition | **Medium** | No re-evaluation of service readiness after root switch |
|
||||||
|

## 5. Phased Implementation Plan
|
||||||
|
|
||||||
|
### Phase 1: Boot Dependency Fix (1–2 weeks)
|
||||||
|
|
||||||
|
**Priority: Unblocks everything downstream.**
|
||||||
|
|
||||||
|
| # | Task | Files | Complexity |
|
||||||
|
|---|------|-------|------------|
|
||||||
|
| 1.1 | Add `acpid = {}` to redbear-device-services.toml and redbear-full.toml | `config/redbear-device-services.toml`, `config/redbear-full.toml` | Low |
|
||||||
|
| 1.2 | Add `requires=` / `wants=` declarations to init service format | `recipes/core/base/source/init/src/` | Medium |
|
||||||
|
| 1.3 | Implement dependency-aware startup: wait for `scheme:<dep>` before starting dependents | `recipes/core/base/source/init/src/` | Medium |
|
||||||
|
| 1.4 | Add `provides= scheme:acpi` / `requires= scheme:acpi` to ACPI-dependent services | Service TOML files | Low |
|
||||||
|
| 1.5 | Wire ESTALE-retry into i2c-hidd/intel-thc-hidd as fallback (already partial) | `drivers/input/i2c-hidd/`, `intel-thc-hidd/` | Low |
|
||||||
|
|
||||||
|
### Phase 2: Intel Display Critical Fixes (3–5 weeks)
|
||||||
|
|
||||||
|
**Priority: Highest impact for bare-metal desktop.**
|
||||||
|
|
||||||
|
| # | Task | Complexity | Risk | Blocks |
|
||||||
|
|---|------|------------|------|--------|
|
||||||
|
| 2.1 | Implement I2C master-mode in i2cd | High | Medium | 2.2, 2.7, 3.1 |
|
||||||
|
| 2.2 | Implement real EDID via DDC (I2C at 0xA0). Fix synthetic_edid to 128 bytes as fallback | High | Medium | — |
|
||||||
|
| 2.3 | Implement hardware vblank (read PIPEFRAME register) | Medium | Low | — |
|
||||||
|
| 2.4 | Implement display watermarks (WM_LINETIME, WM levels per pipe) | High | Medium | — |
|
||||||
|
| 2.5 | Implement eDP panel power sequencing (PP_ON/OFF/CYCLE) | Medium | Medium | — |
|
||||||
|
| 2.6 | Implement hardware cursor (CUR_CTL/CUR_BASE/CUR_POS) | Medium | Low | — |
|
||||||
|
| 2.7 | Implement DP AUX channel (I2C-over-AUX for DisplayPort) | High | Medium | Depends on 2.1 |
|
||||||
|
|
||||||
|
**Ordering:** EDID (2.2) → vblank (2.3) → watermarks (2.4) → panel (2.5) → cursor (2.6) → DP AUX (2.7)
|
||||||
|
|
||||||

### Phase 3: Input Stack Completion (2–4 weeks)
|
||||||
|
|
||||||
|
**Can parallel with Phase 2 once I2C master-mode (2.1) is done.**
|
||||||
|
|
||||||
|
| # | Task | Complexity |
|
||||||
|
|---|------|------------|
|
||||||
|
| 3.1 | Complete intel-thc-hidd input streaming (replace sleep loop with HID report read) | Medium |
|
||||||
|
| 3.2 | Add PS/2 extended protocols (ImPS/2 scroll, Explorer 5-btn, trackpoint) | Medium |
|
||||||
|
| 3.3 | Add input device hotplug (dynamic producer registration in inputd) | Medium |
|
||||||
|
| 3.4 | Add multitouch protocol (ABS_MT slots, touch report parsing) | Medium |
|
||||||
|
| 3.5 | Add pointer acceleration to inputd | Low |
|
||||||
|
| 3.6 | Port bounded subset of Linux hid-quirks for device workarounds | Medium |
|
||||||
|
|
||||||
|
### Phase 4: AML Interpreter Depth (4–8 weeks)
|
||||||
|
|
||||||
|
**Risk gate: scope strictly to _PS0/_PS3/_PRW/_BIF/_BST opcodes first.**
|
||||||
|
|
||||||
|
| # | Task | Complexity |
|
||||||
|
|---|------|------------|
|
||||||
|
| 4.1 | AML While/If-Else/Method-with-locals (bounded, not full spec) | Very High |
|
||||||
|
| 4.2 | OperationRegion handlers for PCI config and I2C | High |
|
||||||
|
| 4.3 | _PRW (power resources for wake) | Medium |
|
||||||
|
| 4.4 | ACPI battery (_BIF/_BST) | Medium |
|
||||||
|
| 4.5 | ACPI buttons (LID, power, sleep) | Low |
|
||||||
|
| 4.6 | Thermal zone evaluation (_TMP, _ACx, _PSV, _CRT) | Medium |
|
||||||
|
|
||||||
|
### Phase 5: Advanced Features (4–8 weeks)
|
||||||
|
|
||||||
|
After Phases 2–4 are stable.
|
||||||
|
|
||||||
|
| # | Task |
|
||||||
|
|---|------|
|
||||||
|
| 5.1 | PCI ASPM power management (_OSC, L0s/L1) |
|
||||||
|
| 5.2 | PCI hotplug (acpiphp/pciehp) |
|
||||||
|
| 5.3 | SRAT/SLIT → NUMA allocator wiring |
|
||||||
|
| 5.4 | Display FIFO underrun recovery |
|
||||||
|
| 5.5 | HPD pulse detection |
|
||||||
|
| 5.6 | I2C bus error recovery (SMBus timeout, multi-controller) |
|
||||||
|
|
||||||
|
### Dependency Graph
|
||||||
|
|
||||||
|
```
|
||||||
|
Phase 1 (boot deps)
|
||||||
|
│
|
||||||
|
├──→ Phase 2 (Intel display) ──→ Phase 5.4, 5.5
|
||||||
|
│ │
|
||||||
|
│ └──→ 2.1 (I2C master) blocks 2.2, 2.7, 3.1
|
||||||
|
│
|
||||||
|
├──→ Phase 3 (input) ──→ 3.1 needs I2C (shared with 2.1)
|
||||||
|
│
|
||||||
|
├──→ Phase 4 (AML) ──→ Phase 5.1, 5.2
|
||||||
|
│ │
|
||||||
|
│ └──→ 4.1 gates 4.3–4.6
|
||||||
|
│
|
||||||
|
└──→ Phase 5 (advanced) ──→ depends on Phases 2, 3, 4
|
||||||
|
```
|
||||||
|
|
||||||
|
### Effort Estimate (2 developers)
|
||||||
|
|
||||||
|
| Phase | Duration | Parallelizable? |
|
||||||
|
|-------|----------|-----------------|
|
||||||
|
| Phase 1 | 1–2 weeks | Yes (with Phase 2 start) |
|
||||||
|
| Phase 2 | 3–5 weeks | Partially (2.1 blocks 2.2–2.7) |
|
||||||
|
| Phase 3 | 2–4 weeks | Yes (parallel with Phase 2) |
|
||||||
|
| Phase 4 | 4–8 weeks | Partially (4.1 gates rest) |
|
||||||
|
| Phase 5 | 4–8 weeks | After Phases 2–4 |
|
||||||
|
| **Total** | **14–27 weeks** | ~8–14 months |
|
||||||
|
|
||||||
|
### Key Risks
|
||||||
|
|
||||||
|
1. **I2C master-mode** is a shared dependency between EDID (2.2), THC input (3.1), and DDC (2.2). Implement it first in i2cd.
|
||||||
|
2. **AML interpreter scope creep** — the full AML spec is enormous. Strictly bound the first pass to opcodes needed for _PS0/_PS3/_PRW/_BIF/_BST. Fallback: bounded userspace AML evaluator in acpid.
|
||||||
|
3. **Intel watermark programming varies by generation** — start with Gen9 Skylake, then generalize.
|
||||||
|
4. **synthetic_edid 112-byte bug** must be fixed IMMEDIATELY — it affects every Intel display attempt.
|
||||||
|
5. **Missing acpid service** in configs must be fixed IMMEDIATELY — it blocks all ACPI-dependent device discovery.
|
||||||
|
6. **DMAR/IOMMU iterator bug** in `acpid/src/acpi/dmar/mod.rs` causes hangs on real hardware; entire DMAR path is commented out.
|
||||||
|
7. **DMI quirk matching is dead** — `redox-driver-sys/quirks/dmi.rs` reads `/scheme/acpi/dmi` but no code provides that scheme.

Version 2.1, February 1999
|
||||||
|
|
||||||
|

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
|
||||||
|
|
||||||
|
[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.]
|
||||||
|
|
||||||
|
Preamble
|
||||||
|
|
||||||
|
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.
|
||||||
|
|
||||||
|
This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.
|
||||||
|
|
||||||
|
When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.
|
||||||
|
|
||||||
|
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it.
|
||||||
|
|
||||||
|
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.
|
||||||
|
|
||||||
|
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library.
|
||||||
|
|
||||||
|
To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others.
|
||||||
|
|
||||||
|
Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.
|
||||||
|
|
||||||
|
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.
|
||||||
|
|
||||||
|
When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library.
|
||||||
|
|
||||||
|
We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances.
|
||||||
|
|
||||||
|
For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License.
|
||||||
|
|
||||||
|
In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system.
|
||||||
|
|
||||||
|
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run.
|
||||||
|
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables.
|
||||||
|
|
||||||
|
The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".)
|
||||||
|
|
||||||
|
"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library.
|
||||||
|
|
||||||

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) The modified work must itself be a software library.
|
||||||
|
|
||||||
|
b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.
|
||||||
|
|
||||||
|
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.
|
||||||
|
|
||||||
|
(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
|
||||||
|
|
||||||
|
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices.
|
||||||
|
|
||||||
|
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.
|
||||||
|
|
||||||
|
This option is useful when you wish to copy part of the code of the Library into a program that is not a library.
|
||||||
|
|
||||||
|
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange.
|
||||||
|
|
||||||
|
If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.
|
||||||
|
|
||||||
|
However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
|
||||||
|
|
||||||
|
When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law.
|
||||||
|
|
||||||
|
If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.)
|
||||||
|
|
||||||
|
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.
|
||||||
|
|
||||||
|
6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications.
|
||||||
|
|
||||||
|
You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things:
|
||||||
|
|
||||||
|
a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.)
|
||||||
|
|
||||||
|
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.
|
||||||
|
|
||||||
|
c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution.
|
||||||
|
|
||||||
|
d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place.
|
||||||
|
|
||||||
|
e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy.
|
||||||
|
|
||||||
|
For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
|
||||||
|
|
||||||
|
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute.
|
||||||
|
|
||||||
|
7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:
|
||||||
|
|
||||||
|
a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.
|
||||||
|
|
||||||
|
b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.
|
||||||
|
|
||||||
|
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
|
||||||
|
|
||||||
|
9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it.
|
||||||
|
|
||||||
|
10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License.
|
||||||
|
|
||||||
|
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
|
||||||
|
|
||||||
|
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation.
|
||||||
|
|
||||||
|
14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Libraries
|
||||||
|
|
||||||
|
If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License).
|
||||||
|
|
||||||
|
To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
|
||||||
|
|
||||||
|
one line to give the library's name and an idea of what it does.
|
||||||
|

||||||

|
||||||
|
This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version.
|
||||||
|
|
||||||
|
This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details.
|
||||||
|
|
||||||
|
You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail.
|
||||||
|
|
||||||
|
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names:
|
||||||
|
|
||||||
