# ACPI Fixes — P0 Phase Tracker
|
||||
|
||||
> **Numbering note:** "P0" refers to the historical hardware-enablement phase (ACPI boot),
|
||||
> not the v2.0 desktop plan phases in `local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md`.
|
||||
|
||||
Status of ACPI fixes for AMD bare metal boot. Cross-referenced with
|
||||
`HARDWARE.md` crash reports and kernel/acpid source TODOs.
|
||||
|
||||
This file is the **historical P0 bring-up ledger**. The forward-looking ownership, robustness, and
|
||||
validation plan now lives in `local/docs/ACPI-IMPROVEMENT-PLAN.md`.
|
||||
|
||||
P0 ACPI boot-baseline work is **materially complete for the historical boot goal**. It should not
|
||||
be read as release-grade ACPI completeness; ownership cleanup, sleep-state support, and bounded
|
||||
bare-metal validation still remain open. Kernel patch is 574 lines, base/acpid patch is 558 lines.
|
||||
|
||||
Where this historical ledger differs from the current source tree, prefer
|
||||
`local/docs/ACPI-IMPROVEMENT-PLAN.md`. In particular, do **not** read older references here to
|
||||
typed `acpid` startup hardening as proof that current-tree boot-path hardening is already complete.
|
||||
Do **not** use this file as the current boot-wiring authority either: initfs lifecycle, `hwd` →
|
||||
`acpid` ad hoc spawning, explicit `RSDP_ADDR` forwarding plus x86 BIOS AML fallback, weak legacy
|
||||
fallback, and provisional `/scheme/acpi/power` semantics are tracked in
|
||||
`local/docs/ACPI-IMPROVEMENT-PLAN.md`.
|
||||
|
||||
## Crash Reports
|
||||
|
||||
| Hardware | Symptom | Root Cause | Status |
|
||||
|----------|---------|------------|--------|
|
||||
| Framework Laptop 16 (AMD 7040) | Crash on boot | Unimplemented ACPI function (jackpot51/acpi#3) | ✅ Fixed for the historical boot-baseline path (RSDP/SDT checksums, MADT NMI types, FADT parse, related bring-up fixes). `acpid` startup hardening still remains open in the current tree. |
|
||||
| Lenovo ThinkCentre M83 | `Aml(NoCurrentOp)` panic at acpid acpi.rs:256 | AML interpreter encounters unsupported opcode | Under investigation (upstream AML issue; not resolved by P0 work) |
|
||||
| HP Compaq nc6120 | Crash after `kernel::acpi` prints APIC info | xAPIC APIC ID read returned raw value, caused page fault on Intel | ✅ Fixed (xAPIC `id()` now shifts `read(0x20) >> 24`) |
|
||||
|
||||
## Known Missing ACPI Table Parsers
|
||||
|
||||
| Table | Location | Status | Impact |
|
||||
|-------|----------|--------|--------|
|
||||
| DSDT (Differentiated System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Platform-specific device config via AML bytecode |
|
||||
| SSDT (Secondary System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Secondary AML tables (hotplug, etc.) |
|
||||
| FACP/FADT | ✅ Full parse in acpid | ✅ Done | PM registers, reset register, sleep states, `\_S5` |
|
||||
| IVRS (AMD-Vi IOMMU) | Removed from acpid stub path | Handled by `iommu` daemon path | ACPI-side broken stub removed; runtime AMD-Vi handling now lives in the separate daemon |
|
||||
| MCFG (PCI Express config space) | Removed (broken stub) | ✅ Handled by pcid | pcid /config endpoint provides direct PCI config space access |
|
||||
| DBG2 (Debug port) | Not implemented | Low | Serial debug port discovery |
|
||||
| BGRT (Boot graphics) | Not implemented | Low | Boot logo preservation |
|
||||
| FPDT (Firmware perf data) | Not implemented | Low | Boot performance metrics |
|
||||
|
||||
IVRS was previously listed as "implemented" but the acpid stub was broken, so it was removed from
|
||||
acpid. AMD-Vi runtime handling now lives in the separate `iommu` daemon path rather than in acpid.
|
||||
MCFG is now handled by pcid's /config endpoint (P1 complete) which provides direct PCI config space
|
||||
access.
|
||||
|
||||
## Implemented ACPI Tables
|
||||
|
||||
| Table | Kernel | Userspace (acpid) | Notes |
|
||||
|-------|--------|-------------------|-------|
|
||||
| RSDP | `acpi/rsdp.rs` | N/A | Signature + checksum validated (ACPI 1.0 + 2.0+ extended) |
|
||||
| RSDT/XSDT | `acpi/rsdt.rs`, `acpi/xsdt.rs` | N/A | Root table pointer iteration + SDT checksum validation |
|
||||
| MADT (APIC) | `acpi/madt/` | N/A | xAPIC + x2APIC (type 0x9) + NMI (0x4, 0xA) + address override (0x5) |
|
||||
| HPET | `acpi/hpet.rs` | N/A | Assumes single HPET |
|
||||
| DMAR (Intel VT-d) | N/A | `acpi/dmar/` (present, not wired) | DMAR parsing code remains in `dmar/mod.rs` but is not initialized at `acpid` startup. Ownership is still transitional/orphaned from `acpid`, not cleanly transferred to a real Intel runtime owner. Iterator bug fixed, re-enabled, safe on AMD (early return) |
|
||||
| FADT | N/A | `acpi.rs` | Full: PM1a/b CNT, reset register, `\_S5` sleep types, GenericAddress I/O |
|
||||
| Power Methods | N/A | `acpi.rs` | `\_PS0`/`\_PS3`/`\_PPC` AML evaluation for device power control |
|
||||
| SPCR | `acpi/spcr.rs` | N/A | ARM64 serial console |
|
||||
| GTDT | `acpi/gtdt.rs` | N/A | ARM64 timers |
|
||||
| Embedded Controller (EC) | N/A | `ec.rs` | Byte-wide and widened accesses (u16/u32/u64) via byte-transaction sequences; timeout on each byte |
|
||||
| AML Mutexes | N/A | `aml_physmem.rs` | Real tracked state with handle-based acquire/release; not a placeholder |
|
||||
| Shutdown via `kstop` | `scheme/acpi.rs` registers `/scheme/kernel.acpi/kstop` | `main.rs` opens kstop and subscribes via `RawEventQueue` | Kernel-to-userspace shutdown signal; `redbear-sessiond` listens on kstop for D-Bus `PrepareForShutdown` |
|
||||
|
||||
## ACPI MADT Entry Types
|
||||
|
||||
All MADT entry types parsed by the kernel. The MADT loop in `x86.rs` dispatches
|
||||
each type to the appropriate handler.
|
||||
|
||||
| Type | Name | Struct | Size | Kernel Action |
|
||||
|------|------|--------|------|---------------|
|
||||
| 0x0 | Processor Local APIC | `MadtLocalApic` | 8 bytes | AP boot via SIPI |
|
||||
| 0x1 | I/O APIC | `MadtIoApic` | 12 bytes | Enumerated |
|
||||
| 0x2 | Interrupt Source Override | `MadtIntSrcOverride` | 10 bytes | IRQ remapping |
|
||||
| 0x4 | Local APIC NMI | `MadtLocalApicNmi` | 4 bytes | LVT NMI programming (xAPIC 0x350/0x360) |
|
||||
| 0x5 | LAPIC Address Override | `MadtLapicAddressOverride` | 10 bytes | Logged (64-bit address) |
|
||||
| 0x9 | Local x2APIC | `MadtLocalX2Apic` | 16 bytes | AP boot via x2APIC ICR (MSR) |
|
||||
| 0xA | Local x2APIC NMI | `MadtLocalX2ApicNmi` | 10 bytes | x2APIC LVT NMI MSR (0x835/0x836) |
|
||||
|
||||
All structs include compile-time size assertions (`assert!(size_of::<T>() == N)`)
|
||||
to catch ABI mismatches early.

|
||||
| 5 | MADT entry length guard | `entry_len < 2` returns None (prevents infinite loop on malformed tables) |
|
||||
| 6 | RSDP checksum validation | ACPI 1.0 + 2.0+ extended checksum |
|
||||
| 7 | SDT checksum validation | `validate_checksum()` method + warn-only on failure |
|
||||
| 8 | CPUID arch split | Separate x86/x86_64 cpuid functions |
|
||||
| 9 | Memory alignment | `find_free_near_aligned()` with power-of-two assert |

| # | Fix | Description |
|
||||
|---|-----|-------------|
|
||||
| 1 | DMAR iterator fix | `type_bytes` renamed to `len_bytes` bug fix + `len < 4` guard |
|
||||
| 2 | DMAR parser/runtime safety fixes | Iterator/length guards were repaired so the DMAR carrier no longer crashes merely by existing; this does **not** mean active `acpid` startup ownership was re-established |
|
||||
| 3 | DMAR not wired into acpid startup | DMAR module present in `dmar/mod.rs` but not imported or called from `main.rs`; this removes active startup ownership from `acpid`, but does not yet establish a clean Intel runtime owner |
|
||||
| 4 | FADT shutdown | `acpi_shutdown()` using PM1a/PM1b CNT_BLK writes with `\_S5` sleep types |
|
||||
| 5 | FADT reboot | `acpi_reboot()` using ACPI reset register via GenericAddress |

| 8 | GenericAddress rename | `GenericAddressStructure` renamed to `GenericAddress` with `is_empty()`, `write_u8()` |
|
||||
| 9 | Reboot wiring | `reboot_requested` flag in main.rs, scheme path detection |
|
||||
| 10 | ivrs/mcfg removed | Broken stub references eliminated (deferred to P2+, handled by pcid) |
|
||||
| 11 | Historical startup-hardening direction | Earlier patch work attempted `StartupError`-style handling, but active current-tree `acpid` still requires Wave 1 boot-path hardening; do **not** treat startup hardening as complete from this ledger alone |

# Bare Metal Validation Log — ACPI and Hardware Evidence
|
||||
|
||||
Template for recording bounded bare-metal validation results on AMD and Intel hardware.
|
||||
Fill one section per test run. Date is ISO 8601.
|
||||
|
||||
This file is an **evidence log**, not the canonical source of support language. For current ACPI
|
||||
status and ownership truth, use `local/docs/ACPI-IMPROVEMENT-PLAN.md`. For hardware-facing support
|
||||
language, use `HARDWARE.md`.
|
||||
|
||||
## How to Test
|
||||
|
||||
```bash
|
||||
# 1. Build the image
|
||||
./local/scripts/build-redbear.sh redbear-full
|
||||
|
||||
# 2. Burn to USB (DANGEROUS — verify target device!)
|
||||
./local/scripts/test-baremetal.sh --device /dev/sdX
|
||||
|
||||
# 3. Boot from USB on target hardware
|
||||
# 4. Record results below
|
||||
```
|
||||
|
||||
## Serial Console Setup
|
||||
|
||||
For boot debugging, connect a serial console before powering on:
|
||||
- Baud rate: 115200
|
||||
- Use a USB-to-TTL serial adapter on the motherboard header
|
||||
- Or use IPMI/BMC serial-over-LAN if available

- Redox version: historical note only; fresh rerun needed
|
||||
- Config: historical pre-rename run; repeat on `redbear-full`
|
||||
- Kernel patch: historical P0 ACPI bring-up patch set (with timeout + SIPI fixes)
|
||||
|
||||
**Result:** Booting
|
||||
|
||||
**Known from current repo docs:**
|
||||
- Previous status: **Broken** — crash due to unimplemented ACPI function
|
||||
- Historical boot-baseline ACPI fixes moved this machine out of the Broken path
|
||||
- Broader bounded validation is still incomplete; a fresh run should replace this carry-forward note

|
||||
- `acpid/src/main.rs:147:39: acpid: failed to daemonize: Error I/O error 5`
|
||||
- Display logs offset past left edge of screen
|
||||
- `[@hwd:40 ERROR] failed to probe with error No such device (os error 19)`
|
||||
|
||||
**Analysis:**
|
||||
- AML interpreter hits unsupported opcode (`NoCurrentOp`)
|
||||
- This is in the userspace `acpid`, not the kernel
|
||||
- Treat this as an unresolved bare-metal failure record until a fresh validation run disproves it

|
||||
|
||||
## Phase 7: Kernel RAM Hang Diagnosis ✅ (2026-04-27)
|
||||
|
||||
### Discovery
|
||||
|
||||
The `redbear-full` harddrive image (4 GiB) boots correctly in QEMU with **2 GiB** of guest RAM,
|
||||
but **hangs silently with 4 GiB or more** — zero kernel serial output after bootloader loads
|
||||
kernel and initfs.
|
||||
|
||||
### Evidence
|
||||
|
||||
| Test | RAM | Result |
|
||||
|------|-----|--------|
|
||||
| `redbear-full` nographic | 2 GiB | ✅ Boots: kernel output, init, services, login prompt |
|
||||
| `redbear-full` nographic | 4 GiB | ❌ Hang: no kernel output, CPU spins in `pause`/`jmp` loop |
|
||||
| `redbear-mini` nographic | 2 GiB | ✅ Boots normally |
|
||||
| `redbear-mini` nographic | 4 GiB | ✅ Boots normally |
|
||||
|
||||
The kernel and initfs binaries are **identical** between `redbear-full` and `redbear-mini`
|
||||
(MD5: `bb5402209aefd7d42c3adaca0682b39f` for kernel, same size for initfs). The bootloader
|
||||
binary is also identical. The only difference is the GPT partition layout (RedoxFS starts at
|
||||
sector 34816 in full vs 4096 in mini).
|
||||
|
||||
QEMU ASM trace (`-d in_asm`) at 4 GiB confirms the kernel executes instructions but **never
|
||||
reaches** `info!("Redox OS starting...")` — it enters a spin-loop before `serial::init()`
|
||||
completes. At 2 GiB, the kernel boots normally and produces full serial output.
|
||||
|
||||
### Root Cause (Analysis)
|
||||
|
||||
The bootloader passes different memory maps to the kernel depending on available RAM. At 2 GiB,
|
||||
the memory map spans ~0x900000–0x7ED3F000 (~2 GiB). At 4 GiB, the map spans a larger range
|
||||
with different reservation patterns. The kernel's `startup::memory::init()` or early SMP
|
||||
bring-up code (`arch/x86_shared/start.rs`) likely encounters an overflow, bad page table
|
||||
mapping, or SMP deadlock on larger memory configurations.
|
||||
|
||||
The spin-loop at the end of the ASM trace (`pause` + `jmp` to self) is consistent with a
|
||||
spinlock wait on a memory location that never gets released — likely SMP bring-up where one
|
||||
CPU waits for another that never initializes.
|
||||
|
||||
### Impact
|
||||
|
||||
| Affected | Not affected |
|
||||
|----------|-------------|
|
||||
| `redbear-full` with ≥4 GiB RAM | `redbear-mini` (any RAM) |
|
||||
| nographic mode specifically | `redbear-grub` (any RAM) |
|
||||
| Real hardware with >2 GiB RAM | All profiles at 2 GiB |
|
||||
| | `make qemu` default (QEMU_MEM=2048) |
|
||||
|
||||
Since `make qemu` defaults to 2048 MiB and all profiles work correctly at that value, **day-to-day
|
||||
development is not affected**. The bug manifests only when developers manually override RAM or
|
||||
when testing on real hardware with larger memory configurations.
|
||||
|
||||
### Recommended Fix
|
||||
|
||||
Add early raw-serial output (`outb` to COM1 port 0x3F8) in `arch/x86_shared/start.rs` **before**
|
||||
`device::serial::init()` as a canary to confirm serial hardware works. Then add instrumentation
|
||||
around the memory map processing in `startup::memory::init()` and SMP bring-up to isolate
|
||||
whether the hang is in memory init, page table setup, or multi-core initialization.

||||

# Red Bear OS — Boot Process Improvement Plan
|
||||
|
||||
**Version:** 1.0 — 2026-04-27
|
||||
**Status:** Active — supersedes ad-hoc boot fixes and replaces historical P0–P6 boot notes
|
||||
**Canonical plans:** `local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md` (v2.0), `local/docs/GREETER-LOGIN-IMPLEMENTATION-PLAN.md`
|
||||
**Diagnosis:** `local/docs/BOOT-PROCESS-ASSESSMENT.md` (Phase 7 kernel RAM hang + ISO organization)

|
||||
|
||||
## 1. Target Contract
|
||||
|
||||
| Profile | Required boot outcome | Current state | Gap |
|
||||
|---------|----------------------|---------------|-----|
|
||||
| `redbear-full` | **Graphical Wayland greeter → KDE desktop session** | Text login only; KWin uses virtual backend | Three blockers |

|

---
|
||||
|
||||
## 2. Current Boot Reality (2026-04-27 Diagnosis)
|
||||
|
||||
### What works
|
||||
|
||||
- UEFI bootloader → kernel → init phase 1/2/3 → services → text login prompt
|
||||
- D-Bus system bus, redbear-sessiond (login1), seatd, redbear-authd, redbear-polkit
|
||||
- redbear-upower, redbear-udisks (read-only)
|
||||
- Framebuffer via vesad (1280×720), fbcond handoff
|
||||
- udev-shim, evdevd input stack
|
||||
- All 37 rootfs units schedule and start
|
||||
|
||||
### What does NOT work
|
||||
|
||||
1. **No graphical login** — `redbear-greeter-compositor` falls back to `kwin_wayland_wrapper --virtual` because `KWIN_DRM_DEVICES` is empty. The Qt6/QML greeter UI never renders.
|
||||
2. **Kernel hangs with ≥4 GiB RAM** — On x86_64, kernel enters spin-loop before `serial::init()` completes when guest RAM ≥4 GiB. `make qemu` default 2048 MiB is unaffected.
|
||||
3. **Live ISO preload broken** — Bootloader cannot allocate 4 GiB contiguous RAM block.
|
||||
|
||||
---
|
||||
|
||||
## 3. Blocker Resolution Plan
|
||||
|
||||
### 3.1 Blocker A: Fix kernel 4 GiB RAM hang
|
||||
|
||||
**Priority:** P0 — blocks real hardware and any QEMU config with >2 GiB RAM.
|
||||
|
||||
**Symptom:** With `-m 4096` (4 GiB guest RAM), the kernel loads but produces zero serial output. CPU trace shows spin-loop (`pause` + `jmp`). With 2 GiB, boots normally.
|
||||
|
||||
**Root cause:** Memory map processing or SMP initialization bug in `startup::memory::init()` or `arch/x86_shared/start.rs` when physical memory exceeds ~2 GiB.
|
||||
|
||||
**Evidence:** Kernel binary identical between mini and full (MD5 confirmed). Mini boots at 4 GiB, full does not. Bootloader, kernel, and initfs are byte-identical across profiles.
|
||||
|
||||
**Files to modify:**
|
||||
|
||||
| File | Change | Why |
|
||||
|------|--------|-----|
|
||||
| `recipes/core/kernel/source/src/arch/x86_shared/start.rs` | Add raw COM1 `outb` before `serial::init()` as canary | Proves serial hardware works; isolates hang point |
|
||||
| `recipes/core/kernel/source/src/startup/memory.rs` | Add debug logging around memory region processing | Identify overflow / bad mapping at large memory sizes |
|
||||
| `recipes/core/kernel/source/src/arch/x86_shared/device/serial.rs` | Ensure COM1 init path is robust for all memory configs | If serial init itself hangs, diagnose why |
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] `make qemu` with `QEMU_MEM=4096` produces `Redox OS starting...` on serial
|
||||
- [ ] Full init sequence completes (phase 1 → phase 2 → phase 3 → login prompt)
|
||||
- [ ] Kernel patch generated, wired into `local/patches/kernel/`, and `recipe.toml` updated per durability policy
|
||||
|
||||
**Estimated effort:** 2–4 days (requires kernel debugging with QEMU GDB)
|
||||
|
||||
---
|
||||
|
||||
### 3.2 Blocker B: Enable DRM/KMS for Wayland compositor
|
||||
|
||||
**Priority:** P0 — KWin needs a real DRM device to render the greeter.
|
||||
|
||||
**Symptom:** `redbear-greeter-compositor: using virtual KWin backend (set KWIN_DRM_DEVICES to enable DRM)`
|
||||
|
||||
**Root cause chain:**
|
||||
|
||||
1. `redox-drm` daemon is not being spawned by `pcid-spawner` for the active GPU
|
||||
2. No `/scheme/drm/card0` device exists
|
||||
3. `KWIN_DRM_DEVICES` environment variable is not set to the correct path
|
||||
4. KWin's `--drm` path never activates
|
||||
|
||||
**Files to modify:**
|
||||
|
||||
| File | Change | Why |
|
||||
|------|--------|-----|
|
||||
| `config/redbear-full.toml` — `20_greeter.service` | Add `KWIN_DRM_DEVICES = "/scheme/drm/card0"` to greeter env | Tells greeter compositor where to find DRM device |
|
||||
| `config/redbear-device-services.toml` | Verify `/lib/pcid.d/` rules are installed with correct paths and vendor/class match patterns | pcid-spawner needs matching rules to auto-spawn redox-drm |
|
||||
| `local/recipes/gpu/redox-drm/source/src/main.rs` | Add startup logging (which PCI device matched, driver initialized, scheme registered) | Diagnostic visibility — confirms daemon runs |
|
||||
| `local/recipes/system/redbear-greeter/source/redbear-greeter-compositor` | Add `KWIN_DRM_DEVICES` awareness and fallback logging | Already partially done — verify env propagation from init service |
|
||||
|
||||
**QEMU-specific fix:** The `virtio-vga` device (vendor `0x1AF4`, class `0x0300`) needs a pcid rule. Check if `config/redbear-full.toml`'s `virtio-gpud.toml` matches.
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] `redox-drm` daemon appears in `ps` after boot (or logs "DRM daemon started" in boot log)
|
||||
- [ ] `/scheme/drm/card0` is accessible from the guest
|
||||
- [ ] `KWIN_DRM_DEVICES` is set and points to `/scheme/drm/card0`
|
||||
- [ ] `redbear-greeter-compositor` logs "using DRM KWin backend" instead of "virtual"
|
||||
- [ ] QEMU VNC framebuffer shows the Qt6/QML greeter UI (not bootloader menu)
|
||||
|
||||
**Estimated effort:** 3–5 days (pcid matching + DRM device node plumbing + env wiring)
|
||||
|
||||
---
|
||||
|
||||
### 3.3 Blocker C: Wire the Qt6/QML greeter UI
|
||||
|
||||
**Priority:** P1 — requires Blocker B resolved first.
|
||||
|
||||
**Symptom:** Text login prompt only. The greeter compositor starts but the Qt6/QML UI never renders.
|
||||
|
||||
**Root cause chain:**
|
||||
|
||||
1. KWin compositor needs a DRM backend to create a Wayland display (→ Blocker B)
|
||||
2. `redbear-greeterd` starts the compositor, waits for Wayland socket, then launches `redbear-greeter-ui`
|
||||
3. If compositor uses virtual backend, the greeter UI may still try to connect to a Wayland display that doesn't exist or lacks rendering
|
||||
4. Qt6 plugin path and QML import path must be correct for the greeter UI to load
|
||||
|
||||
**Files to verify/modify:**
|
||||
|
||||
| File | Check/Change | Why |
|
||||
|------|-------------|-----|
|
||||
| `local/recipes/system/redbear-greeter/source/src/main.rs` | Verify greeterd waits for compositor Wayland socket before launching UI | Race condition if UI starts before compositor is ready |
|
||||
| `local/recipes/system/redbear-greeter/source/redbear-greeter-compositor` | Verify `WAYLAND_DISPLAY` is exported and matches what the UI expects | UI connects to compositor via this socket |
|
||||
| `local/recipes/system/redbear-greeter/source/ui/main.cpp` | Add diagnostic logging: "UI started, connecting to compositor..." | Visibility into UI launch |
|
||||
| `local/recipes/system/redbear-greeter/source/ui/Main.qml` | Verify Qt6 QML imports resolve at runtime | Missing QtQuick/QtWayland imports cause silent failure |
|
||||
| `local/recipes/system/redbear-greeter/recipe.toml` | Verify Qt plugin, QML, and asset paths in `package.files` | UI binaries need Qt runtime files staged in sysroot |
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] `redbear-greeterd` logs "compositor ready, launching greeter UI"
|
||||
- [ ] `redbear-greeter-ui` process appears in `ps`
|
||||
- [ ] Qt6/QML greeter login screen visible on the display (QEMU VNC)
|
||||
- [ ] Text input field accepts username, password field accepts password
|
||||
- [ ] Login attempt reaches `redbear-authd` (visible in authd logs)
|
||||
|
||||
**Estimated effort:** 3–5 days (compositor-to-UI handoff + Qt runtime path validation)
|
||||
|
||||
---
|
||||
|
||||
### 3.4 Blocker D: Session handoff after successful login
|
||||
|
||||
**Priority:** P1 — requires Blocker C resolved first.
|
||||
|
||||
**Symptom:** Unknown — haven't reached this stage yet. Expected gap: after `redbear-authd` authenticates, `redbear-session-launch` starts the KDE session but KWin/Plasma may fail.
|
||||
|
||||
**Files to verify:**
|
||||
|
||||
| File | Check | Why |
|
||||
|------|-------|-----|
|
||||
| `local/recipes/system/redbear-authd/source/src/main.rs` | `start_session()` flow: does it call session-launch correctly? | Authd initiates the session launch after successful auth |
|
||||
| `local/recipes/system/redbear-session-launch/source/src/main.rs` | Verify uid/gid drop, env setup, `dbus-run-session` invocation | Session needs correct user context and D-Bus session bus |
|
||||
| `config/wayland.toml` | Verify canonical KWin launch env (`KWIN_DRM_DEVICES`, `XDG_RUNTIME_DIR`, `QT_*` paths) | KWin session needs same DRM/seat/Qt env as greeter |
|
||||
| `local/recipes/kde/kwin/` | Verify `kwin_wayland_wrapper` binary is staged and executable | KWin wrapper must be in PATH for session launch |
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] Successful login in greeter triggers session launch
|
||||
- [ ] `redbear-session-launch` starts with correct UID/GID
|
||||
- [ ] D-Bus session bus starts for the user session
|
||||
- [ ] `kwin_wayland_wrapper --drm` starts as the user session compositor
|
||||
- [ ] `plasmashell` starts (or at minimum, a KWin desktop surface appears)
|
||||
|
||||
**Critical gap:** `redbear-kde-session` — the script that `redbear-session-launch` invokes for the KDE session — was not found in the source tree. This script or binary must be created/staged at `/usr/bin/redbear-kde-session`. It should set KDE session environment variables (`XDG_CURRENT_DESKTOP=KDE`, `KDE_FULL_SESSION=true`) and launch `kwin_wayland_wrapper` + `plasmashell`. The upstream KWin Wayland service entry (`plasma-kwin_wayland.service.in`) provides a reference template.
|
||||
|
||||
**Estimated effort:** 4–7 days (session handoff + KDE session bring-up + missing script creation)

### 3.5 Non-blocker: Fix live ISO preload
|
||||
|
||||
**Priority:** P2 — live mode is a convenience, not required for graphical login.
|
||||
|
||||
**Symptom:** `live: disabled (unable to allocate 4078 MiB upfront)` — even with 6 GiB guest RAM.
|
||||
|
||||
**Fix:** Modify bootloader in `recipes/core/bootloader/source/src/main.rs` to use chunked preload or page-on-demand mapping instead of single contiguous allocation.
|
||||
|
||||
**Estimated effort:** 2–3 days

## 4. Execution Order
|
||||
|
||||
```
|
||||
Phase 1 (P0): Fix kernel 4 GiB RAM hang
|
||||
└── Unblocks real hardware testing and 4 GiB QEMU configs
|
||||
|
||||
Phase 2 (P0): Enable DRM/KMS for Wayland
|
||||
└── redox-drm auto-spawn + KWIN_DRM_DEVICES wiring
|
||||
└── Unblocks KWin --drm mode
|
||||
|
||||
Phase 3 (P1): Wire Qt6/QML greeter UI
|
||||
└── Requires Phase 2 (DRM backend for compositor)
|
||||
└── Deliverable: visible greeter login screen on framebuffer
|
||||
|
||||
Phase 4 (P1): Session handoff
|
||||
└── Requires Phase 3 (greeter auth working)
|
||||
└── Deliverable: post-login KDE session starts
|
||||
|
||||
Phase 5 (P2): Fix live ISO preload
|
||||
└── Independent of phases 1–4
|
||||
└── Deliverable: ISO boots with live mode enabled
|
||||
```
|
||||
|
||||
### Parallel work opportunities
|
||||
|
||||
- **Phase 5** (live ISO) can proceed in parallel with Phases 1–4
|
||||
- Within Phase 2: pcid rule creation and KWIN_DRM_DEVICES env wiring are independent
|
||||
- Within Phase 3: greeterd protocol fixes and Qt6 path validation are independent
|
||||

||||
|
||||
### Phase 1 additional verification (4 GiB):
|
||||
|
||||
```bash
|
||||
# After fix, verify 4 GiB no longer hangs:
|
||||
qemu-system-x86_64 -nographic -m 4096 [rest of flags] | grep "Redox OS starting"
|
||||
# Must produce the kernel startup line

## Build Artifacts (ISO Organization)
|
||||
|
||||
All profiles produce outputs under `build/x86_64/`. Each profile gets its own directory:
|
||||
|
||||
| Profile | ISO | harddrive.img | Image size | QEMU RAM | Boots via `make qemu`? |
|
||||
|---------|-----|---------------|------------|----------|------------------------|
|
||||
| `redbear-mini` | `redbear-mini.iso` | `redbear-mini/harddrive.img` | 1.5 GiB | **2 GiB** | ✅ Text login |
|
||||
| `redbear-grub` | `redbear-grub.iso` | `redbear-grub/harddrive.img` | 1.5 GiB | **2 GiB** | ✅ Text login |
|
||||
| `redbear-full` | `redbear-full.iso` | `redbear-full/harddrive.img` | 4.0 GiB | **2 GiB** | ⚠️ Text login only |
|
||||
|
||||
> **⚠️ CRITICAL**: `redbear-full` requires **exactly 2 GiB** of guest RAM in QEMU. With 4 GiB or more, the kernel hangs silently during early SMP/memory initialization (x86_64 only). This is a confirmed kernel bug — see `BOOT-PROCESS-ASSESSMENT.md` Phase 7. The `make qemu` default of `QEMU_MEM=2048` is correct for all profiles.
|
||||
|
||||
### Known QEMU Issues
|
||||
|
||||
| Issue | Profiles affected | Workaround |
|
||||
|-------|-------------------|------------|
|
||||
| **Kernel hang with ≥4 GiB RAM** (nographic mode) | `redbear-full` | Use `-m 2048` or less. `make qemu` default is 2048, safe. |
|
||||
| **Graphical login fallback** — greeter uses text login, not Wayland | `redbear-full` | Set `KWIN_DRM_DEVICES=/dev/dri/card0` in greeter env; verify redox-drm daemon is running |
|
||||
| **Live ISO preload** — `unable to allocate 4078 MiB upfront` | `redbear-full` | Disable live mode (press `l` at bootloader); preload needs chunked allocation |
|
||||
| **EFI EDID unavailable** — `Failed to get EFI EDID` warning | All | Expected in QEMU; not a project issue |
|
||||
| **AHCI DVD I/O error** — empty DVD-ROM port probe | All | Benign; non-blocking |
|
||||
|
||||
### ISO naming convention
|
||||
|
||||
- **Profile ISOs**: `redbear-{profile}.iso` (e.g. `redbear-full.iso`, `redbear-mini.iso`)
|
||||
- **Legacy names** (`redbear-live-mini.iso`, `redbear-live-full.iso`) are **deprecated** and should not be used in new scripts or documentation.
|
||||
- `scripts/build-iso.sh` accepts profile names: `redbear-full`, `redbear-mini`, `redbear-grub`.
