Both require DMC firmware; firmware keys for GuC/HuC/GSC added. Three new tests cover the device-ID lookups and firmware-key strings. -- **Phase 3 (Redox EGL platform):** **deferred**. The original - `src/egl/drivers/dri2/platform_redox.c` was removed in upstream Mesa - ~25.0; the existing patches 03/06 are orphaned and cannot apply to - Mesa 26.1.4. A standalone re-creation was attempted but the Mesa - 26.1.4 DRI2 API has shifted since. Documented in - `local/patches/mesa/26.1.4-defer-redox-platform.patch` for follow-up. +- **Phase 3 (Redox EGL platform):** **NOW WIRED** (`9ff9b4b0e2`). Re-creates + `src/egl/drivers/dri2/platform_redox.c` for Mesa 26.1.4 (the file + was removed in upstream Mesa ~25.0; the orphaned patches 03/06 + were placeholders that no longer apply). The platform: + - Opens `/scheme/drm/card0` via `loader_get_driver_for_fd` (which + goes through libdrm's redox patch to `scheme:drm/`) + - Falls back to swrast when no DRM device is present + - Supports pbuffer surfaces (the only sensible thing on Redox + without a real windowing system) + - Wired through `EGL_PLATFORM_REDOX_REDBEAR` (Red Bear extension + ID 0x31E0) with the HAVE_REDOX_PLATFORM guard + - Build verified: `meson setup` succeeds, `ninja + src/egl/libEGL_mesa.so.0.0.0` links cleanly with platform_redox.c. + - Fixed API mismatches against the 2022-RedoxOS-fork source tree + (`__DRIdrawable` → `struct dri_drawable`; removed + `flush_get_images`/`image_get_buffers` from `dri2_egl_display_vtbl`; + removed `use_invalidate` from loader_extensions; replaced + `dri2_load_driver_dri3` with the implicit load via + `dri2_create_screen`; removed `dri2_setup_extensions` which is + gone in 26.1.4). +- **Phase 4 (Intel iris):** was enabled in commit `08f3e71d41` but + reverted in `e1fc194c06` because both iris and the Intel Vulkan + driver require `-Dwith_clc -> dependency("libclc")`, which is not + ported to Redox. The recipe is back to the working set + (`softpipe,llvmpipe,virgl`). +- **Phase 5 (AMD radeonsi):** same status as Phase 4 — reverted + pending libclc port. +- **Phase 6 (Vulkan):** same status — reverted pending libclc port. - **Phase 4 (Intel iris):** added `iris` to `-Dgallium-drivers` in `local/recipes/libs/mesa/recipe.toml`. Compile-side. **Note:** `kmsro` was removed in Mesa 26.1.4 (no longer a valid option).
