## Status Correction (2026-04-14)
Most of this document is a historical roadmap and no longer reflects the repository's current state.
Use the matrix below as the authoritative phase summary before reading the older milestone text.
| Layer / Phase | Current repo state | Evidence |
|---|---|---|
| P0 ACPI / bare-metal boot | Complete in-tree | `local/docs/ACPI-FIXES.md`, `local/patches/kernel/redox.patch`, `local/patches/base/redox.patch` |
| P1 driver infrastructure | Complete in-tree, compile-oriented | `local/recipes/drivers/redox-driver-sys/`, `local/recipes/drivers/linux-kpi/`, `local/recipes/system/firmware-loader/` |
| P2 DRM / AMD+Intel display | Complete in-tree, hardware validation pending | `local/docs/P2-AMD-GPU-DISPLAY.md`, `local/recipes/gpu/redox-drm/`, `local/recipes/gpu/amdgpu/` |
| P3 POSIX + input | Implemented in-tree; consumer-visible `signalfd`/`timerfd`/`eventfd`/`open_memstream` header-export path fixed in this repo pass; runtime validation still pending | `recipes/core/relibc/source/src/header/`, `recipes/core/relibc/source/include/sys/signalfd.h`, `local/patches/relibc/`, `local/recipes/system/evdevd/`, `local/recipes/system/udev-shim/` |
| P4 Wayland stack | Partially complete | `recipes/wip/wayland/`, `recipes/wip/libs/other/libinput/`, `recipes/wip/services/seatd/` |
| P5 AMD acceleration / IOMMU | Partial | `local/recipes/gpu/amdgpu/`, `local/recipes/system/iommu/` (now buildable via surfaced recipe) |
| P6 KDE Plasma | In progress with mixed real builds and stubs/shims | `config/redbear-kde.toml`, `local/recipes/kde/`, `local/docs/QT6-PORT-STATUS.md` |
### Ordered Remaining Gaps
1. **Validate the completed P3→P4 bridge in practice**: `libwayland` now rebuilds with `signalfd`, `timerfd`, `eventfd`, `open_memstream`, `MSG_CMSG_CLOEXEC`, and `MSG_NOSIGNAL` restored, but compositor/runtime validation is still outstanding.
2. **Complete P4 runtime path**: libinput/seatd/GBM/Wayland compositor integration is still incomplete even though the base libraries now build, `seatd` now builds for Redox, and the KDE runtime config now starts a seatd service.
3. **Separate KDE real builds from scaffolding**: parts of the KDE stack are genuine builds, while others are shimmed or stubbed only to satisfy dependency resolution.
4. **Hardware validation remains open** for AMD/Intel DRM and the IOMMU path, even though the IOMMU daemon now builds.
### P7 Note
The repository's tracked phase model currently stops at **P6**. What a user might call "P7"
only appears here as later milestone-style work (for example M7/M8 below), not as a first-class
implemented phase with its own config/recipe/doc boundary.

## Concrete Roadmap with Milestones
### Milestone M1: "libwayland works natively" (2-4 weeks)
- Implement 7 POSIX APIs in relibc (see Layer 1 table)
- Remove `redox.patch` from libwayland recipe
- Build-side part now substantially complete: relibc exports the needed consumer-visible POSIX headers/symbols and `libwayland` rebuilds with only residual Redox-specific build tweaks
- Remaining work: runtime validation (`wayland-rs_simple_window`, compositor bring-up)
- **Test**: `wayland-rs_simple_window` runs without crashes
- **Delivers**: libwayland, wayland-protocols, libdrm all build natively
