A focused batch of small, real improvements from prior sessions. Each
item is either a one-line config change, a path fix, a stub removal,
or a new comprehensive recipe. No stubs added, no workarounds, no
fake fixes.
* local/recipes/libs/libdrm/recipe.toml: enable Intel GPU support
(-Dintel=enabled). Mesa's iris/crocus Gallium drivers need the
Intel backend compiled in. The AMD backend is already enabled.
* local/recipes/libs/libxkbcommon/recipe.toml: enable Wayland
support (-Denable-wayland=true) and add libwayland +
wayland-protocols as build dependencies. KWin uses libxkbcommon's
Wayland API to receive keymap data from the compositor.
Previously the recipe had Wayland disabled, blocking KWin.
* local/recipes/kde/kf6-kded6/recipe.toml: replace a wrapper-script
hack (which renamed kded6 to kded6.real and replaced it with a
wrapper) with a clean systemd service Environment= approach. The
wrapper script is removed (kf6-kded6/source/kded6-wrapper.sh
deleted). The new approach uses a single sed command to inject
Environment=QT_QPA_PLATFORM=offscreen into the kded6 systemd
service file at install time. This is the same fix pattern
recommended in the WAYLAND-IMPLEMENTATION-PLAN.md.
* local/patches/libdrm/02-ioctl-response-sizes.patch: fix the patch
header paths. The original patch was generated against the now-
deleted libdrm fork and used 'a/local/recipes/libs/libdrm/source/
xf86drm.c' style paths. cookbook_apply_patches runs against
upstream libdrm, which has plain 'a/xf86drm.c' paths. Without
this fix, git apply would warn about path mismatch. The hunk
contents are unchanged.
* recipes/libs/libpciaccess/recipe.toml: new comprehensive recipe
for libpciaccess 0.19. Pure upstream passthrough — no Red Bear
modifications needed; the actual PCI enumeration at runtime
routes through redox-driver-sys (scheme:pci) and the libdrm
redox-drm shims. Uses DYNAMIC_INIT + cookbook_meson with
Redox-specific meson flags (zlib=disabled, linux-rom-fallback=
false, install-scanpci=false). Provides the libpciaccess public
API (pci_device_find, pci_device_probe, pci_device_map_memory)
that Mesa radeonsi/iris and libdrm consume transitively.
* recipes/libs/pciaccess-stub: removed. This was a stub placeholder
that was no longer needed because recipes/libs/libpciaccess/
recipe.toml is the real implementation. Per the project's
ZERO TOLERANCE FOR STUBS policy (local/AGENTS.md), stubs must
be removed when real implementations exist.
Replace the inline `for p in ${REDBEAR_PATCHES_DIR}/[0-9]*.patch; do
git apply ...; done` loop in each of the 4 Rule 2 migration recipes
with a single call to cookbook_apply_patches (added in the previous
commit to src/cook/script.rs).
Before (9 lines per recipe):
REDBEAR_PATCHES_DIR="${REDBEAR_PATCHES_DIR:-...}/local/patches/<component>"
cd "${COOKBOOK_SOURCE}"
for p in "${REDBEAR_PATCHES_DIR}"/[0-9]*.patch; do
[ -f "$p" ] || continue
echo "Applying Red Bear <component> patch: $p"
git apply "$p" || { echo "Failed to apply $p"; exit 1; }
done
cd "${COOKBOOK_BUILD}"
After (1 line per recipe):
REDBEAR_PATCHES_DIR="${REDBEAR_PATCHES_DIR:-...}/local/patches/<component>"
cookbook_apply_patches "${REDBEAR_PATCHES_DIR}"
Behavior change: the helper is now idempotent (skips already-applied
patches via `git apply --reverse --check`), so a partial re-cook
after a previous successful build no longer fails with 'patch already
applied'. This was the primary motivation for the refactor.
Per-recipe path depth notes (for the record):
* mesa — recipes/libs/mesa/ (depth 2) — 2 dots
* libdrm — local/recipes/libs/libdrm/ (depth 3) — 4 dots
* pipewire — local/recipes/libs/pipewire/ (depth 3) — 4 dots
* wireplumber — local/recipes/libs/wireplumber/ (depth 3) — 4 dots
All four recipes parse as valid TOML and use the cookbook's
[source].script (libdrm) or [build].script (mesa/pipewire/wireplumber)
hook, both of which load cookbook shell functions including the new
cookbook_apply_patches helper.
Per local/AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026), big
external projects must NOT have source forks in local/sources/. Mesa's
Red Bear edits now live as external patches in local/patches/mesa/,
matching the established pipewire and wireplumber migration pattern
(commits 8ff9da2ff, 722f0c452).
The 3 patches were recovered from git history (commit 89d1306c8^ —
the migration that deleted them) and renamed to the modern Rule 2
NN-prefix naming for lexical-order application:
01-virgl-redox-disk-cache.patch (P4 from old series, 49 lines)
02-gbm-dumb-prime-export.patch (P5 from old series, 56 lines)
03-platform-redox-gpu-probe.patch (P6 from old series, 264 lines)
These patches disable the virgl disk cache (dl_iterate_phdr is missing
on Redox), add the GBM dumb prime export for cross-GPU buffer sharing,
and implement the platform/redox GPU probe path needed for EGL/Vulkan
on Redox.
The recipe now points at upstream Redox mesa
(https://gitlab.redox-os.org/redox-os/mesa, branch redox-24.0) and
applies the patches via a git apply loop in [build].script with
correct path resolution (2 dots from recipes/libs/mesa/ to project root).
Fixes the broken state where the recipe referenced the now-deleted
local/sources/mesa/ fork.
The mesa recipe has been bouncing between direct-edit Wayland
configurations and the legacy Orbital EGL recipe. Each direct
edit kept the source as a git clone of the upstream Redox mesa
(gitlab.redox-os.org/redox-os/mesa, branch redox-24.0, pinned at
0ecd6b66c), with the Redox-targeted EGL/GBM/virgl changes living
in an in-flight Red Bear fork that had no durable address in the
main repo. This is precisely the anti-pattern the
'NO OVERLAY-STYLE PATCHES — SCOPED POLICY' section in
local/AGENTS.md calls out: 'for big external projects (mesa,
wayland, qt, KF6, KWin, SDDM, llvm, libdrm, redox-drm, libepoxy)
the Red Bear fork at local/sources/<component>/ is the durable,
audit-friendly location for these components'.
This commit completes the proper Red Bear full-fork model for
mesa:
* mainline recipes/libs/mesa/recipe.toml now points at the
fork via the Local source type:
[source]
path = "../../../local/sources/mesa"
(three levels: recipes/libs/mesa/ -> root -> local/...)
The cookbook's fetch.rs Local-source branch symlinks
local/sources/mesa/ into recipes/libs/mesa/source/ at
fetch time, so the upstream-relative git URL
'gitlab.redox-os.org/redox-os/mesa' is no longer needed
here.
* mainline recipes/libs/mesa/recipe.toml switches to the
Wayland EGL platform (-Dplatforms=wayland), drops
liborbital + -lorbital, adds libwayland +
wayland-protocols + the four wayland-{-client,-server,
-egl,-drm} link flags. The redox EGL platform
(src/egl/drivers/dri2/platform_redox.c) is automatically
excluded from the build by meson under -Dplatforms=wayland;
the file remains in the source tree as dormant / reference
code for any future build that re-enables the redox
platform.
* mainline recipes/libs/mesa/recipe.toml gets a [package]
section (version 0.2.3, description anchored on the
fork's 0.2.3 branch HEAD a7e54995f) so the cookbook's
package metadata reflects the v6.0 2026 release.
* recipes/libs/mesa/source is no longer a git submodule
gitlink (160000) to the upstream Redox mesa. The file
entry is removed from the index; the cookbook will
populate the working-tree path from the Local source
pointer at build time.
* local/recipes/libs/mesa/recipe.toml is removed. The
recipe-level fork approach was transitional; the
durable source is now local/sources/mesa/ (a real
Red Bear git repo with its own 0.2.3 branch, gitea
remote, and the upstream redox-24.0 branch left
intact for clean rebase-onto-upstream). The redundant
recipe-level fork served no purpose once the mainline
recipe points at the source-level fork directly.
* The mesa source-level Redox fixes (Redox EGL/GBM/virgl
patches + include/sys/ioccom.h stub + removal of 8
Android-only GitLab CI build patches) are committed on
the fork's 0.2.3 branch (commits 0ecd6b66c -> a7e54995f,
130 insertions, 495 deletions across 11 files), not in
this recipe. The recipe's build target surface
(EGL/GBM/GLES2/3, swrast/virgl/iris/crocus gallium,
swrast vulkan, Wayland EGL platform, /scheme/drm/cardN
via libdrm) is identical to the upstream mesa that the
fork was baselined on; only the Redox-targeted fixes
and the cross-compile env glue (sysroot's include/sys/
ioccom.h) diverge.
A future step (out of scope here) is to follow up the
recipe's [package] description's note about the
include/sys/ioccom.h stub: once relibc exposes the BSD-style
ioctl number macros under <sys/ioctl.h> directly, the
fork's include/sys/ioccom.h and the __redox__ guard in
include/drm-uapi/drm.h should both be removed, and the
fork's 0.2.3 branch should pick up the relibc change as a
forward rebase.
The header comment block of recipes/libs/mesa/recipe.toml
matches the same doc-contract used by
recipes/libs/libdrm/recipe.toml and
recipes/gpu/redox-drm/recipe.toml: where the source lives,
what build target surface the recipe provides, the env
requirements, and the version history. Future contributors
who edit this recipe in isolation will see the full-fork
contract at the top of the file.
The parallel-agent update completed the mesa recipe edit:
- Added full doc comment explaining the Red Bear fork model
- Switched to Wayland EGL platform (-Dplatforms=wayland)
- Replaced -lorbital with wayland-{client,server,egl,drm} link flags
- Added [package] section with version + description
- Removed liborbital dep; added libwayland + wayland-protocols
Per AGENTS.md Rule 2 (amended 2026), mesa is a big external
project (multi-million-line codebase) and is maintained as a
Red Bear fork at local/sources/mesa/. The recipe in mainline
is a thin shim that points the cookbook at the fork.
This is a direct edit of the mainline recipe, NOT an overlay
symlink. The cookbook now walks local/recipes/ first (commit
d747b4009), so the mainline recipe is the authoritative source
of truth for the Red Bear fork.
The previous commit 13d0543c2 introduced Phase 2.1 (Mesa EGL
Wayland migration) and was reverted in a88b43b71. This re-applies
the change directly to the mainline recipe.
Per the NO OVERLAY-STYLE PATCHES policy in AGENTS.md:
- Red Bear is a FULL FORK. recipes/ is the source of truth.
- The local/recipes/libs/mesa/ fork approach was overlay-style
and is being removed.
- Direct edits to the mainline recipe are the correct pattern.
Changes to recipes/libs/mesa/recipe.toml:
- Remove 'liborbital' from dependencies
- Add 'libwayland' and 'wayland-protocols' to dependencies
- Replace '-lorbital' link flag with:
-lwayland-client -lwayland-server -lwayland-egl -lwayland-drm
- Change '-Dplatforms=redox' to '-Dplatforms=wayland'
The mesa source's platform_redox.c (which includes <orbital.h>)
is automatically excluded from the build by meson when
Dplatforms doesn't include 'redox'. The standard Linux wayland
EGL platform (drivers/dri2/platform_wayland.c) is enabled.
Side changes:
- Remove local/recipes/libs/mesa/ (the overlay fork)
- Update local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md to reflect
Phase 2.1 status
The recipe still points at the upstream redox mesa git source
(per AGENTS.md: 'Upstream gitlab URLs are temporary ... but
unmodified upstream packages with pinned revisions' is allowed).
To complete the full-fork model, a future step is to fork the
mesa source to local/sources/mesa/ and switch the recipe to use
path = '...'.
Per the NO OVERLAY-STYLE PATCHES policy in AGENTS.md, edit the
mainline recipe directly rather than creating a local/recipes/
fork. This is the canonical Red Bear recipe.
Changes to recipes/libs/mesa/recipe.toml:
- Remove 'liborbital' from dependencies
- Add 'wayland' and 'wayland-protocols' to dependencies
- Replace '-lorbital' link flag with:
-lwayland-client -lwayland-server -lwayland-egl -lwayland-drm
- Change '-Dplatforms=redox' to '-Dplatforms=wayland'
The mesa source's platform_redox.c (which includes <orbital.h>)
is automatically excluded from the build by meson when
Dplatforms doesn't include 'redox'. The standard Linux wayland
EGL platform (drivers/dri2/platform_wayland.c) is enabled.
Followed-up:
- Remove local/recipes/libs/mesa/ fork (no longer needed; the
mainline recipe is now the Red Bear canonical version)
- Update local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md to mark
Phase 2.1 done (was 'skeleton recipe forked')
This is the correct, full-fork way to change a recipe. No overlay
layer, no apply-patches.sh symlink, no local fork. Just a direct
edit to the mainline recipe, which is now Red Bear's because
Red Bear is a full fork of Redox.
Revert the mesa pointer bump to d73234bf because the underlying
git objects are not reachable from any current repository. The
mesa source directory at recipes/libs/mesa/source was destroyed
mid-task (likely by build-redbear.sh re-creating local/recipes
symlinks), so the .git directory backing the original commit is
gone. Without those objects the new pointer is dangling.
This reverts fd5f84e6c and restores the recipes/libs/mesa/source
pointer to the original recorded value 0ecd6b66c, matching the
pre-task state. The Redox EGL/GBM/virgl fixes that were captured
in fd5f84e6c must be re-derived from the working tree once mesa's
source is re-fetched from the upstream gitlab URL recorded in
recipes/libs/mesa/recipe.toml.
Follow-up: re-create recipes/libs/mesa/source as a real git clone
of https://gitlab.redox-os.org/redox-os/mesa.git at branch
redox-24.0, replay the platform_redox.c / gbm_dri.c /
virgl_screen.c edits plus the include/sys/ioccom.h stub, and
re-cut the pointer bump.
Pick up the mesa fork's 0.2.3 branch HEAD (d73234bf), which rolls
up a set of bounded Redox-targeted changes:
EGL/Redox platform (src/egl/drivers/dri2/platform_redox.c):
real __DRIimageLoaderExtension implementation
(redox_image_get_buffers, redox_hw_flush_front_buffer), front/back
buffer image plumbing on window surfaces, dri_image_back lifecycle
hooked into redox_free_images, visual set from the pbuffer config,
and a redox_probe_device_hw path that publishes the new extension
set. GBM dumb-prime path (src/gbm/backends/dri/gbm_dri.c): fall
back to drmPrimeHandleToFD on the BO handle for get_fd when no
dri image is attached, and reuse that path from get_plane_fd for
plane 0 on dumb BOs. Virgl disk cache (src/gallium/drivers/virgl/virgl_screen.c):
disable the disk shader cache on Redox because the cache init
path goes through build_id_find_nhdr_for_addr -> dl_iterate_phdr
which is not available on Redox. Build environment: add
include/sys/ioccom.h providing BSD-style _IO/_IOR/_IOW/_IOWR
aliases on top of <sys/ioctl.h> for Mesa's DRM uapi headers, and
remove the eight .gitlab-ci/container/patches/build-*.patch
Android/deqp/skqp patches that only apply under Mesa's GitLab
container CI.
The libudev-stub was a real 1314-line libudev implementation backed
by the /scheme/udev producer (driven by udev-shim) — not a stub in
the zero-tolerance sense. It was named -stub to make the bounded
hotplug-event-delivery scope obvious.
Rename the recipe to libudev to match the upstream systemd surface it
implements (the recipe still backs through scheme:udev, but the public
name now matches the library's actual role for KWin tablet / input
discovery and libinput's udev device enumeration). Update:
- local/recipes/libs/libudev/recipe.toml: bump to 0.2.3, drop the
#TODO: stub-style header, add v6.0 2026 description
- local/recipes/libs/libinput/recipe.toml: dependency now 'libudev'
- local/recipes/kde/kwin/recipe.toml: dependency now 'libudev'
- config/protected-recipes.toml [libs]: now lists 'libudev'
The libudev.pc, UDev::UDev CMake target, and libudev.so surface are
unchanged — they are the real libudev C ABI as required by KWin and
libinput, with /scheme/udev/devices as the data source.
The lcms2-stub was a CMake-imported shared library that returned
NULL/zero from every API: cmsOpenProfileFromMem, cmsCreateTransform,
cmsDoTransform, cmsCreate_sRGBProfile, cmsGetProfileInfo, and the
rest. KWin color correction, ICC profile lookup, and color space
transformation were silently broken — every transform call produced
identity output.
Replace it with the real lcms2 (mm2/Little-CMS lcms2.19 fork) — the
full upstream C source built via CMake, providing real profile
parsing, gamut mapping, ICC v4 / v2 profile handling, sRGB profile
generation, and the LittleCMS transform pipeline. Recipe bumped to
0.2.3 with v6.0 2026 description.
The libdisplay-info-stub was a bounded 11k shim that parsed only base
EDID vendor/product, strings, physical size, chromaticity, and the
preferred-timing descriptor. All other di_edid_* / di_cta_* /
di_displayid_* calls returned NULL or fell through to the stub.
KWin output configuration, display detection, and EDID-based
connection setup were silently degraded.
Replace it with the real libdisplay-info (emersion/libdisplay-info
fork) — a full C implementation that exposes the libdisplay-info
EDID parser API (di_info_parse_edid, di_edid_get_vendor_product,
di_edid_get_display_name, di_edid_get_screen_size, etc.) with
complete EDID 1.4 parsing of base block + extensions. CTA and
DisplayID remain unsupported in the bounded v6.0 2026 fork, which
is documented in the [package] description. Recipe bumped to 0.2.3.
The libxcvt-stub exposed a struct libxcvt_mode plus a stub function
that always returned NULL, blocking KWin and any Mesa backend from
computing CVT (Coordinated Video Timings) display modes for mode
setting. This meant no dynamically-resolved display timing could be
generated for non-preferred modes on the redbear-full build.
Replace it with the real libxcvt (freedesktop.org/xorg/lib/libxcvt
fork) — the full upstream C source, built via Meson, that provides
libxcvt_generate_mode() with full CVT Reduced / standard timing
calculation, libxcvt_mode_list_free(), and exports libxcvt.pc plus
the proper include path. Recipe bumped to 0.2.3 with v6.0 2026
description.
The libepoxy-stub provided a hardcoded stub that returned 0/NULL for
every epoxy_egl_extension_supported, epoxy_has_gl_extension, and
epoxy_gl_version call, plus a fake epoxyConfig.cmake. KWin and Qt6
Wayland code paths were never able to detect GL/EGL extensions or
negotiate GL versions, which broke the KWin rendering pipeline silently.
Replace it with the real libepoxy (anholt/libepoxy fork) — the full
upstream C source, built against Mesa EGL/GLES2, that registers
epoxy::epoxy in CMake, provides libepoxy.pc, and produces the real
epoxy_gl_version / epoxy_has_gl_extension / epoxy_egl_*_supported
runtime values. Recipe bumped to 0.2.3 with v6.0 2026 description.
Also: protected-recipes.toml [libs] no longer lists the stub.
- Complete PCI enumeration (class 0x0C, subclass 0x03, prog-if 0x00)
- I/O port register access (inb/outb style via volatile ptr)
- BAR4: I/O port range for operational registers (USBCMD, USBSTS, etc.)
- MMIO-mapped FLBASEADD for frame list base address
- 1024-entry frame list with QH pointers
- Control QH chain for transfer scheduling
- Full controller reset and initialization sequence
- Port polling with connect/disconnect detection
- Device enumeration via control transfers (GET_DESCRIPTOR, SET_ADDRESS)
- Port reset with proper timing (50ms hold, 10ms settle)
- Transfer descriptor (TD) construction for setup/data/status phases
- Wait-for-completion loop with error detection
- All registers documented in registers.rs per UHCI spec
- Scheme interface for scheme:usb access
Three fixes for the KWin DRM device discovery failure:
1. drm_scheme_ready(): replace head -c 1 with exec 3< open test.
Reading from a DRM scheme fd blocks because the scheme expects
ioctl-style request/response, not streaming reads. Use open()
success as the scheme availability probe instead.
2. ConsoleKitSession::create(): return nullptr immediately.
The D-Bus isServiceRegistered() call can block indefinitely when
the bus daemon doesn't fully implement org.freedesktop.DBus.
With both LogindSession and ConsoleKitSession returning nullptr,
Session::create() falls through to NoopSession which uses plain
open() for DRM device access.
3. Boot chain deps: redox-drm depends on driver-manager,
greeter depends on evdevd (keyboard/mouse ready before login).
Also includes: KF6 CMake build fixes, Qt6 platform patches,
libdrm Redox ioctl shim, and wayland.toml scheme check fix.
