The current baseline is **Red Bear OS 0.1.0** (Redox snapshot at build-system commit `f55acba68`).
All recipe sources are pinned and archived in `sources/redbear-0.1.0/`.
## BUILD SYSTEM DURABILITY — THE CARDINAL RULE
**THE `recipes/*/source/` DIRECTORY WILL ALWAYS BE REWRITTEN. DO NOT EVER USE IT FOR ANY
WORK THAT YOU INTEND TO KEEP. THOSE TREES ARE EPHEMERAL — THEY ARE DESTROYED AND REGENERATED
ON EVERY `repo fetch`, `repo cook`, `make clean`, AND `make distclean`. ANY EDIT MADE THERE
WILL BE SILENTLY LOST ON THE NEXT BUILD. COMMITTING TO A SUBMODULE INSIDE `source/` DOES NOT
PROTECT YOUR WORK — THE ENTIRE DIRECTORY IS DELETED AND RE-CLONED/RE-EXTRACTED FROM SCRATCH.**
This is the #1 mistake AI agents and new contributors make. It has caused repeated work loss
in this project. The rule is:
| What you want to do | Where to do it |
|---|---|
| Change a kernel source file | Create or update a patch in `local/patches/kernel/` |
| Change an init or daemon source file | Create or update a patch in `local/patches/base/` |
| Change relibc | Create or update a patch in `local/patches/relibc/` |
| Change a driver | Create or update a patch in `local/patches/base/` or `local/patches/<driver>/` |
| Add a new package | Create a recipe in `local/recipes/<category>/<name>/` |
| Change build config | Edit `config/redbear-*.toml` |
| Add documentation | Write to `local/docs/` |
### How the build system works
```
repo cook <package>
├── repo fetch <package>
│ ├── Clone/fetch upstream source → recipes/<pkg>/source/
│ ├── Apply patches from recipe.toml → patches are read from local/patches/<pkg>/
│ └── Source tree is now fully patched and ready for build
├── Cargo/cmake/configure build
└── Stage artifacts into sysroot
```
The `source/` directory is a disposable working copy. It is produced at the start of every
build by cloning the upstream source + applying patches sequentially. The recipe's
`patches = [...]` list in `recipe.toml` controls which patches are applied.
### Two-layer architecture
```
Layer 1: Ephemeral (destroyed on clean/fetch/rebuild)
recipes/<pkg>/source/ ← working tree, cloned + patched
build/ ← build outputs
target/ ← cargo target dir
Layer 2: Durable (survives clean/fetch/rebuild/release provisioning)
local/patches/<pkg>/ ← .patch files — the actual source code changes
local/recipes/<pkg>/ ← custom recipe directories
config/redbear-*.toml ← Red Bear OS build configs
local/docs/ ← planning and integration docs
recipes/<pkg>/recipe.toml ← the patches list (git-tracked)
```
### The correct workflow for any source change
1. **Make the change** in `recipes/<pkg>/source/` to validate it compiles
2. **Generate a patch**: `cd recipes/<pkg>/source && git diff > ../../../local/patches/<pkg>/my-fix.patch`
3. **Wire the patch**: add `"my-fix.patch"` to the recipe's `recipe.toml` `patches = [...]` list
4. **Validate**: `./target/release/repo validate-patches <pkg>`
5. **Rebuild**: `./target/release/repo cook <pkg>`
6. **Commit**: `git add local/patches/ recipes/<pkg>/recipe.toml && git commit`
### Common anti-patterns
| Anti-pattern | Why it fails |
|---|---|
| Editing `source/` files then running `make all` | `make all` calls `repo fetch` which regenerates `source/` — edits are lost |
| Creating a patch but not wiring it into `recipe.toml` | Patch file exists but is never applied — build uses unpatched source |
| **Hand-writing patches manually** | **FORBIDDEN. Unified diffs hand-written by humans routinely have incorrect line counts, wrong context, malformed hunks, or timestamp headers — all of which cause `patch(1)` to reject them. The ONLY acceptable way to generate patches is `git diff -U0 -w` from a committed source tree baseline.** |
| Editing `recipe.toml` patches list without creating the actual `.patch` file | Build fails with "missing patch" error |
| Editing `recipe.toml` patches list without creating the actual `.patch` file | Build fails with "missing patch" error |
| Expecting `source/` changes to survive `make clean` | `make clean` deletes `source/` directories |
| Running `repo cook` without `--allow-protected` for core packages | Protected recipes (kernel, relibc, base) are offline-only by default |
### Patch file location convention
- `local/patches/base/` — for the `base` package (init, daemon, all drivers)
- `local/patches/kernel/` — for the kernel
- `local/patches/relibc/` — for relibc
- `local/patches/installer/` — for the installer
- `local/patches/bootloader/` — for the bootloader
- `local/patches/<package>/` — for any other patched package
### Recipe patch wiring
Each recipe's `recipe.toml` lists patches relative to `local/patches/<pkg>/`:
```toml
[source]
git = "https://gitlab.redox-os.org/redox-os/base.git"
rev = "463f76b96..."
patches = [
"P0-daemon-fix-init-notify-unwrap.patch", # applied first
"P9-init-scheduler-completed.patch", # applied second
# ... more patches
]
```
Patches are applied in listed order. Dependencies between patches must be respected (a patch
that defines a type must come before a patch that uses it).
### Kernel-specific notes
The kernel source at `recipes/core/kernel/source/` is a separate git worktree (rev `866dfad`).
The kernel recipe is at `recipes/core/kernel/recipe.toml` and patches are at
`local/patches/kernel/`. The same durability rules apply — all kernel changes must be
in `local/patches/kernel/*.patch`, never in the `source/` tree directly.
## NO SILENT UPSTREAM PULLS — OFFLINE-FIRST POLICY

## BUILD SYSTEM POLICIES
### Build Durability Rule — Every Build Lands in the Repo
Every successful `repo cook` produces two durable artifacts:
1. **Package in the repo**: `repo/x86_64-unknown-redox/<name>.pkgar` + `<name>.toml`
2. **Patched source form**: All source modifications are in `local/patches/<component>/` and wired into `recipe.toml`
A build is **not complete** until both artifacts exist:
```bash
# After cooking, verify the package is in the repo
./target/release/repo find <package>
# Check the repo manifest exists
ls repo/x86_64-unknown-redox/<package>.toml
ls repo/x86_64-unknown-redox/<package>.pkgar
```
If a package was built but the repo artifacts are missing, the build did not complete.
Re-run `repo cook <package>` to regenerate them.
If source patches were applied but not mirrored to `local/patches/`, see the
DURABILITY POLICY section above.
### Cascade Rebuild Rule
When a low-level package changes (relibc, kernel, base, or any library), **all
packages that depend on it must be rebuilt**. A stale dependent silently produces
link errors, ABI mismatches, or runtime crashes.
Use the cascade rebuild script:
```bash
# Rebuild relibc and everything that depends on it
./local/scripts/rebuild-cascade.sh relibc
# Dry run: show what would be rebuilt without building
./local/scripts/rebuild-cascade.sh --dry-run relibc
# Multiple root packages
./local/scripts/rebuild-cascade.sh relibc ncurses
```
The script:
1. Finds all packages whose `recipe.toml` lists the target in `dependencies`
2. Transitively expands the reverse dependency graph (BFS)
3. Builds the root package(s) first, then dependents in order
4. Pushes all rebuilt packages to the sysroot
**When to use cascade rebuilds:**
- After changing relibc headers or ABI
- After rebuilding a shared library (ncurses, zlib, openssl, etc.)
- After kernel ABI changes that affect userspace
- After any change to a package listed in other packages' `dependencies`
**When NOT to use cascade rebuilds:**
- Standalone applications with no dependents (editors, games, utilities)
- Terminal/leaf packages that nothing depends on
### Atomic Patch Application
The cookbook tool (`src/cook/fetch.rs`) applies patches **atomically**:
@@ -645,78 +466,12 @@ Patches may use either format:
Git-specific headers (`diff --git`, `diff -ruN`, `index`, `new file mode`, `rename from/to`,
`similarity index`, `dissimilarity index`) are automatically stripped before
`patch` is invoked. The build system uses `--fuzz=3` for resilient context matching.
`patch` is invoked. The build system uses `--fuzz=0` for strict context matching.
**Timestamps in `---`/`+++` lines** (common in `diff -ruN` output) should be removed.
Use `--- a/path` and `+++ b/path` without timestamps. The `normalize_patch` function
does NOT strip timestamps — they should be removed from the patch file directly.
### Robust Patch Generation (REQUIRED)
**MANDATORY: All patches MUST be generated using `git diff -U0 -w` from a committed source tree.
Hand-writing unified diffs is FORBIDDEN — it routinely produces incorrect line counts, malformed
hunks, or timestamp headers that cause `patch(1)` to reject them. The build system uses
`--fuzz=3` for resilient context matching, which requires properly generated diffs.**
Context-line mismatches (renamed variables, shifted line numbers, upstream refactors)
are the single largest source of patch application failures. Use the zero-context,
whitespace-ignored technique to make patches resilient to drift:
**Workflow (mandatory):**
```bash
# 1. Start with a clean P0..P(N-1) source tree (repo fetch already applied earlier patches)
cd recipes/<component>/source
# 2. Commit the P0..P(N-1) state as a git baseline
git add -A && git commit -m "P0..P(N-1) baseline"
# 3. Make P(N) edits in the source tree
# (edit files, test compile, etc.)
# 4. Generate the P(N) patch using ONLY git diff -U0 -w:
git diff -U0 -w > ../../../local/patches/<component>/P<N>-<description>.patch
# 5. Wire the patch into recipe.toml patches list
# 6. Validate: repo validate-patches <package>
# 7. Rebuild: repo cook <package>
# 8. Commit: git add local/patches/ recipes/<pkg>/recipe.toml && git commit
```
**Apply (for manual testing):**
```bash
patch -p1 --fuzz=3 < local/patches/<component>/P<N>-<description>.patch>
```
**Why this works:**
- `-U0` produces zero lines of surrounding context, so the patch has no fragile context
lines that can drift when surrounding code changes
- `-w` ignores all whitespace changes, so indentation-only refactors don't break the patch
- `--fuzz=3` allows `patch(1)` to find the target location even when nearby lines have shifted
- Together these three flags eliminate the entire class of "context mismatch" failures
**Why hand-writing is forbidden:**
- Human-written diffs routinely have wrong `@@` line counts, missing or extra context lines,
incorrect `--- a/` / `+++ b/` paths, or embedded timestamps — all of which cause `patch(1)`
to reject the patch or silently apply it to the wrong location
- The `git diff -U0 -w` command produces mechanically correct diffs every time
**Before this technique**, patches routinely broke when:
- A variable was renamed (e.g., `deamon` → `daemon` in context)
- Lines were added or removed above the changed code
- Indentation was reformatted
- An earlier patch in the chain shifted line numbers
**With this technique**, patches survive all of the above. A hunk consists only of the
changed lines themselves — no context that can go stale.
**Conventions:**
- Always use `--- a/path` and `+++ b/path` headers (no timestamps)
- Always name patches `P<N>-<description>.patch` with sequential numbering
- Always wire patches into `recipe.toml` `patches = [...]` in application order
- Always validate with `repo validate-patches <package>` after creating or editing a patch
- When updating an existing patch, regenerate it entirely rather than editing line numbers manually

# RED BEAR OS — DERIVATIVE OF REDOX OS
## INTERNAL-FIRST POLICY
When building packages, resolving dependencies, or choosing between implementations,
**always prefer internal Red Bear recipes and patched sources** over upstream or
third-party alternatives. This applies at every decision point:
| Decision | Always prefer |
|----------|--------------|
| Recipe location | `local/recipes/` over `recipes/` (upstream) |
| Patch source | `local/patches/` over in-tree edits or ad-hoc sed |
| Source tarball | Patched archive in `sources/redbear-0.1.0/tarballs/` over re-download |
| Implementation | Red Bear Rust implementation over upstream C port |
| Config | `config/redbear-*.toml` over mainline `config/*.toml` |
| Scripts | `local/scripts/` over ad-hoc shell commands |
**Concretely:** if `local/recipes/<category>/<name>/` exists and is symlinked into the
recipe tree, that is the authoritative recipe — never fall back to the upstream
`recipes/` version. If a local recipe has a `redox.patch`, that patch is the
maintained Red Bear delta — never work around it by editing the source tree directly.
**Rationale:** the local overlay is the durable, version-controlled, release-safe layer.
Upstream recipes are disposable and may be overwritten by `make distclean` or release
provisioning. Only `local/` survives across rebuilds and releases.
## TUI CONVENTION — `-i` INTERACTIVE SWITCH
All Red Bear desktop applications that offer a TUI mode MUST use `-i`/`--interactive`

**No exceptions. No "temporary." No "until we fix it properly."**
## BUILD DURABILITY AND CASCADE POLICY
### Every Build Lands in the Repo
Every successful `repo cook <package>` MUST produce two durable artifacts:
1. **Package in the repo**: `repo/x86_64-unknown-redox/<name>.pkgar` + `<name>.toml`
2. **Patched source form**: All source modifications mirrored to `local/patches/<component>/`
A build is **not complete** until both exist. Verify after every cook:
```bash
./target/release/repo find <package> # Must find the package
ls repo/x86_64-unknown-redox/<package>.toml # Manifest must exist
ls repo/x86_64-unknown-redox/<package>.pkgar # Archive must exist
```
If a package was built but the repo artifacts are missing, the build did not complete.
If source patches exist only in `recipes/*/source/` but not in `local/patches/`,
the patches are not durable (see Source-of-Truth Rule below).
### Cascade Rebuild Rule
When a low-level package changes, **all packages that transitively depend on it
must be rebuilt**. A stale dependent silently produces link errors, ABI mismatches,
or runtime crashes.
```bash
# Rebuild relibc and everything that depends on it
./local/scripts/rebuild-cascade.sh relibc
# Dry run: show what would be rebuilt without building
./local/scripts/rebuild-cascade.sh --dry-run relibc
# Multiple root packages
./local/scripts/rebuild-cascade.sh relibc ncurses
```
The script performs BFS over reverse dependencies: it finds all packages whose
`recipe.toml` lists the target in `dependencies`, transitively expands, then builds
root-first followed by dependents.
**Always use cascade rebuilds after changing:**
- relibc (headers, ABI, any patches)
- Kernel (syscall ABI changes)
- Shared libraries (ncurses, zlib, openssl, etc.)
- Any package listed in other packages' `dependencies`
**Example:** Changing relibc's `sys/types/internal.h` header requires rebuilding
bison, m4, flex, and every other gnulib-based package that includes system headers
through the relibc include chain.

# 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) |

## 8. Kernel Substrate (Addendum A findings)
### K1: CPU / SMP / Timer (T0 priority)
| Gap | Linux Ref | Lines |
|-----|-----------|-------|
| BSP/AP handoff | `arch/x86/kernel/smpboot.c:895` | 1,511 |
| CPU hotplug | `smpboot.c:1312` | — |
| TSC calibration | `arch/x86/kernel/tsc.c:1186` | 1,612 |
| APIC timer calibration | `arch/x86/kernel/apic/apic.c:294` | 2,694 |
| Vector allocation | `arch/x86/kernel/apic/vector.c` | 1,387 |
| MSI/MSI-X | `arch/x86/kernel/apic/msi.c` | 391 | ✅ DONE — P8-msi.patch (msi.rs, vector.rs, scheme/irq.rs, driver-sys) |
### 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.
### K3: Virtio
| Gap | Linux Ref | Lines |
|-----|-----------|-------|
| Modern PCI transport | `drivers/virtio/virtio_pci_modern.c` | 1,301 |
| Packed virtqueue | `drivers/virtio/virtio_ring.c` | 3,940 |
| Multiqueue | `drivers/net/virtio_net.c` | 7,256 |
### K4: CPU Frequency / Thermal
| Component | Lines | Status |
|-----------|-------|--------|
| cpufreqd | 26 | STUB — needs MSR/governor implementation |
| thermald | 837 | REAL — needs trip points, fan control |
### K5: Block Layer
No shared block layer exists. Each storage driver reinvents I/O dispatch. Linux: `block/blk-mq.c` (5,309 lines).

## 9. ACPI Gaps (delegated to ACPI-IMPROVEMENT-PLAN.md)
| Linux File | Lines | Feature | Status |
|------------|-------|---------|--------|

## 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()
