rtcd: syscall::openat(0, '/scheme/sys/update_time_offset') used fd 0
(stdin) instead of the namespace fd, causing EACCES. Fixed by using
libredox::call::getns().
acpid: AmlPhysMemHandler captured pci_fd at construction as
Arc<Option<Fd>>, so after set_pci_fd() stored the fd, the handler
never saw it. Changed to Arc<RwLock<Option<Fd>>> shared between
AcpiContext and the handler.
Base fork commits: 770694d0 (rtcd), 84573feb (acpid)
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.
The cub AUR→RBPKGBUILD→recipe.toml conversion pipeline (located at
local/recipes/system/cub/source/) was assessed end-to-end against
12 representative real-world PKGBUILDs:
- libevdev (simple meson)
- fd-find (cargo)
- libpciaccess 0.18.1 (meson)
- fmt (cmake)
- wlroots-git (git source, complex deps)
- libpciaccess 0.19 (extra/-style, meson + ninja)
- ffmpeg (configure + options)
- mesa 24.3 (git+url + multi-source + pkgver())
- gzip (configure + git source + check)
- zlib (simple C, configure)
- openssl (pkgbase split package)
- glib2 (complex deps, real-world)
The assessment found 8 critical bugs that would prevent cub from
producing working Red Bear recipes for any real Arch package. 7 of
the 8 bugs were fixed in the previous commit (7c5b1f36e); the 8th
(custom-template recipes lack DYNAMIC_INIT and cookbook_apply_patches
boilerplate) is deferred as a cookbook-integration concern.
This commit adds two artifacts of the assessment:
1. local/docs/cub-assessment-and-improvement-plan.md (508 lines,
~28KB): the complete assessment document. Sections:
- Executive summary (architecture decision + 8-bug verdict)
- What cub does well (10+ working cases)
- The 8 bugs (location, severity, root cause, fix)
- Test methodology
- Test cases by category (A: conversion success, B: dep mapping,
C: source URL, D: build template, E: edge cases, F: validation)
- Forward improvement plan (16 items in 4 tiers)
- Appendix A: cub architecture map (CLI + 17 modules)
- Appendix B: RBPKGBUILD format spec
- Appendix C: Generated recipe format vs. real Red Bear recipe
2. local/recipes/system/cub/source/cub-assessment/:
a 12-PKGBUILD integration test harness. A standalone binary that
exercises the conversion pipeline on each PKGBUILD and reports
status, warnings, action_items, recipe validity (TOML), and the
first 30 lines of the generated recipe. Used to verify the bug
fixes in 7c5b1f36e — all 12 cases convert successfully
post-fix, including the previously-erroring mesa 24.3 (which
now produces a valid recipe with a multi-source warning).
The test harness lives next to the cub source (cub-assessment/) and
has its own Cargo.toml with [workspace] empty so it doesn't join the
cub workspace. Build/run with:
cd local/recipes/system/cub/source
cargo run --manifest-path cub-assessment/Cargo.toml
The harness is intended for use by future cub maintainers to catch
regressions. It's not wired into CI yet — that would be a separate
task.
After running an empirical assessment of cub's AUR→RBPKGBUILD→recipe
pipeline against 12 representative real-world PKGBUILDs (libevdev,
fd-find, libpciaccess, fmt, wlroots-git, ffmpeg, mesa 24.3, gzip,
zlib, openssl, glib2, plus a libpciaccess extra/-style variant), 7
critical bugs were found that would prevent any real Arch package
from converting to a working Red Bear recipe.
Fixes (all surgical, in cub-lib/src/):
1. deps.rs: drop glibc dependency (was: mapped to relibc, which is
wrong because relibc is the Redox C library and is part of the
OS, not a package). glibc is a tautology on Redox and must be
omitted. The empty mapping triggers the standard 'omitted' path
in map_dep_list with a clear 'has no Redox mapping' warning.
2. deps.rs: drop gcc-libs dependency (was: mapped to gcc, which
conflates the runtime libgcc/libstdc++ with the compiler).
gcc-libs is provided by relibc on Redox and must be omitted.
3. deps.rs: prefix build tools (meson, ninja, cmake, make,
pkg-config, autoconf, automake, libtool, git, perl, python,
rust, cargo, llvm, clang, swig, bison, flex, doxygen, and ~50
more) with 'host:' so the Redox cookbook knows they're host-only
and not part of the cross-compiled target. The new BUILD_TOOLS
constant lists all known build tools; map_dependency returns
'host:<name>' for entries in this set.
4. pkgbuild.rs: parse AUR-style 'git+url#tag=branch' source syntax.
The new split_source_fragment function strips the 'git+' prefix,
extracts the '#tag=...' or '#branch=...' or '#commit=...'
fragment, and maps to the Redox cookbook's [source].branch or
[source].rev field. The previous behavior kept the literal
'git+...#tag=...' URL in the recipe, which is invalid Redox
cookbook format.
5. pkgbuild.rs: support multi-source PKGBUILDs. Real packages like
mesa have 2+ sources (git repo + extra file). The previous
behavior errored on multi-source with 'multiple sources not yet
supported'. Now: keep the first source as primary, warn about
the rest, and continue conversion. Auxiliary sources are listed
in the warning message so the user can re-add them.
6. pkgbuild.rs: preserve options=() flags (e.g., '!lto', '!strip',
'!emptydirs') in the new RBPKGBUILD compat.options field.
Previously dropped silently.
7. pkgbuild.rs: substitute \${pkgver}, \${pkgname}, etc. in source
URLs by piping each entry through resolve_shell_vars before
converting. The previous behavior kept the literal '\${pkgver}'
in the URL, making the recipe's [source].tar URL invalid.
All fixes verified by:
- cub-assessment: 12 PKGBUILDs all convert and produce valid TOML.
The mesa 24.3 case (which previously errored on multi-source) now
produces a valid recipe with a warning. ffmpeg's glibc is now
correctly dropped. All build tools (meson, ninja, etc.) are
correctly host: prefixed. All AUR git+url sources parse
correctly into branch/rev fields.
- cargo test --workspace: 72 passing (up from 70 — added 2 new
tests for the build-tool prefixing and gcc-libs dropping).
The 8th known issue (custom-template recipes lack DYNAMIC_INIT and
cookbook_apply_patches boilerplate) is deferred — it's a separate
cookbook-integration concern tracked in the cub assessment plan
(local/docs/cub-assessment-and-improvement-plan.md).
This is the final cleanup batch for the Rule 2 big-project migration
work (pipewire, wireplumber, mesa, libdrm all migrated to upstream git
+ external patches in local/patches/<component>/).
Changes:
* local/recipes/libs/libdrm/recipe.toml: upgrade from
template = 'meson' + mesonflags to template = 'custom' +
DYNAMIC_INIT + cookbook_apply_patches + cookbook_meson. This
matches the structural pattern used by the other 3 Rule 2
migration recipes (mesa, pipewire, wireplumber) and gives libdrm
the same flexible shell-script build context for future
cross-compilation tweaks. Adds build dependencies expat,
libpciaccess, meson, ninja-build, pkgconf (the meson template
had these implicit; the custom template requires them explicit).
Patch application still goes through cookbook_apply_patches
(4 dots from local/recipes/libs/libdrm/ to project root).
* local/recipes/AGENTS.md: catalog update reflecting the libdrm
template change (now 'custom' instead of 'meson') and adding
catalog entries for 4 recipes that were created during this
migration round but were missing from the catalog: libxkbcommon,
pam-redbear, pipewire, wireplumber.
* sources/redbear-0.1.0/manifest.json: add a new manifest entry
for 'libs/libdrm' (the historical 0.1.0 archive entry for libdrm,
which uses the patched tarball). This mirrors the existing
'lib/libdrm' entry and gives 'repo restore' a consistent way to
recover the libdrm source from the 0.1.0 release archive.
* Doc updates: AGENTS.md, README.md, local/AGENTS.md,
local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md, local/docs/GPU-MESA-
KDE-CHAIN-ASSESSMENT.md, local/recipes/AGENTS.md: bring the
docs in line with the Rule 2 policy and the 4-migration set
(pipewire, wireplumber, mesa, libdrm). Most are catalog or
cross-reference updates.
* local/docs/STUBS-FIX-PROGRESS.md: heavily trimmed (-303 net).
The old document was tracking 346+ stub fixes from earlier
sessions; most of those are now closed and the document has
been condensed to the current state.
* local/docs/SOURCE-OWNERSHIP-MODEL.md: deleted (-89 lines).
This old doc described a 'source ownership' concept that has
been superseded by the amended AGENTS.md Rule 2 (NO OVERLAY-
STYLE PATCHES — SCOPED POLICY) section, which is the canonical
source-ownership model going forward.
Two related cleanups for the libdrm Rule 2 migration (commit 5f5eec1c4):
* libwayland: add -Dscanner=false to cookbook_meson, with a 20-line
comment explaining the rationale. Without this flag, libwayland's
meson.build builds a `wayland-scanner` executable for the *target*
(Redox). The resulting binary has /lib/ld64.so.1 as its ELF
interpreter (Redox's loader) and is useless on the build host. The
pkgconfig that libwayland installs (wayland-scanner.pc) then points
`wayland_scanner` to this Redox binary, and downstream consumers
(mesa, wayland-protocols) pick it up via
dependency('wayland-scanner'). When the cookbook's redoxer sandbox
tries to exec it on the host, the host kernel can't find
/lib/ld64.so.1 and the build fails with 'required file not found'.
Disabling the scanner means libwayland doesn't install
wayland-scanner to the sysroot. Downstream consumers then fall
through to the host's /usr/bin/wayland-scanner (a proper
x86_64-linux-gnu binary that works on the build host). This
matches what wayland-protocols already does in its own meson.build
(see its redox.patch in the recipe).
* libdrm: remove 4 orphaned source-cache files that were left over
from the libdrm Local source fork at local/sources/libdrm/ (deleted
in commit 5f5eec1c4). The 4 files were the in-tree Red Bear edits
that are now external patches in local/patches/libdrm/:
- source/virtgpu_drm.h DELETED (was in 01-drm-ioctl-bridge.patch)
- source/xf86drm.c MODIFIED (most edits moved to patch)
- source/xf86drmMode.c MODIFIED (most edits moved to patch)
- source/xf86drm_redox.h DELETED (was in 01-drm-ioctl-bridge.patch)
The local/recipes/libs/libdrm/source/ cache is now empty (only
upstream files) and is regenerated by 'repo cook' from the upstream
git URL specified in the recipe. These 4 files are no longer
touched by the build system.
Fixes the build correctness issue where downstream mesa/wayland-protocols
builds would fail with 'required file not found: /lib/ld64.so.1' due to
wayland-scanner being built for the wrong target. The fix mirrors what
upstream Redox's wayland-protocols recipe does in its own meson.build.
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 (mesa, libdrm, wayland, qt, KF6, KWin, SDDM,
llvm, libepoxy, pipewire, wireplumber) apply their Red Bear edits as
external patches in local/patches/<component>/[0-9]*.patch on top of
the upstream checkout. Recipes for these projects previously inlined
the same 7-line bash loop (`cd $COOKBOOK_SOURCE; for p in
.../*.patch; do git apply ...; done; cd $COOKBOOK_BUILD`).
The cookbook_apply_patches helper centralizes this loop and adds
three quality improvements over the inline version:
1. Idempotence: each patch is checked with `git apply --reverse
--check` before applying. If the patch is already applied (e.g.
a partial re-cook after a previous successful build), the helper
skips it instead of failing with 'patch already applied'.
2. Failure accounting: applied/skipped/failed counts are reported
at the end of the run, so a single failed patch doesn't silently
abort the entire build chain.
3. Single source of truth: any future change to the patch application
semantics (e.g. supporting 3-way merges, --3way, or a different
check algorithm) happens in one place, not across 12+ recipes.
The helper is loaded into every recipe's build environment via the
existing cookbook shell-script injection in src/cook/script.rs and is
called as:
cookbook_apply_patches "${REDBEAR_PATCHES_DIR}"
This commit is the cookbook-side change. The 4 existing Rule 2
migration recipes (mesa, libdrm, pipewire, wireplumber) are refactored
in the next commit to call this helper instead of inlining the loop.
Per local/AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026), big
external projects must NOT have source forks in local/sources/. libdrm's
Red Bear edits now live as external patches in local/patches/libdrm/,
matching the established pipewire and wireplumber migration pattern
(commits 8ff9da2ff, 722f0c452).
The 5 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-drm-ioctl-bridge.patch (P1 from old series, 278 lines)
02-ioctl-response-sizes.patch (P1 from old series, 30 lines)
03-drm-get-pci-info.patch (P2 from old series, 153 lines)
04-drm-get-version-driver-name.patch (P3 from old series, 34 lines)
05-drmGetDeviceFromDevId-redox.patch (P4 from old series, 68 lines)
These patches add the Redox-side ioctl/ioctl-com and scheme: dispatch
path needed by redox-drm and Mesa radeonsi/iris.
The recipe now points at upstream libdrm 2.4.125
(https://gitlab.freedesktop.org/mesa/libdrm, tag libdrm-2.4.125) and
applies the patches via a [source].script hook (the cookbook's
"Optional script to run to prepare the source" field) with a
REDBEAR_PATCHES_DIR computed from COOKBOOK_RECIPE.
Fixes the broken state where the recipe referenced the now-deleted
local/sources/libdrm/ fork.
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.
Per local/AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026), big
external projects must NOT have source forks in local/sources/. PipeWire's
Red Bear edits now live as external patches in local/patches/pipewire/,
matching the established mesa, libdrm, and wireplumber migration pattern.
The patch contains the redox_compat/ shim headers (byteswap.h,
sys/mman.h) that bridge relibc gaps for the meson subprojects, the
__redox__ guards in src/pipewire/mem.c for the memfd_create emulation
on the redox ramfs scheme, and the __redox__ stubs in
src/pipewire/thread.c for pthread_setname_np and
sched_get_priority_min/max. It also includes the README-redbear.md
fork gap analysis and a small number of build script adjustments for
cross-compilation under the Redox toolchain.
The local/sources/pipewire/ fork is preserved as a historical reference
of the migration baseline but no longer used by the build system. A
follow-up commit will remove it after we verify a clean rebuild from
upstream git + the external patch.
The recipe's REDBEAR_PATCHES_DIR uses ../../../.. (four dots) to
correctly resolve to local/patches/pipewire/ from the recipe's depth
(local/recipes/libs/pipewire/recipe.toml). The mesa and libdrm
migrations shipped a path-count typo (one short); this recipe uses
the correct depth per local/AGENTS.md.
Per local/AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026), big
external projects must NOT have source forks in local/sources/. WirePlumber's
Red Bear edits now live as external patches in local/patches/wireplumber/,
matching the established mesa and libdrm migration pattern.
The patch contains the redox_compat/ shim headers that bridge relibc gaps
for the meson subprojects, and any build script adjustments for cross-
compilation under the Redox toolchain.
The local/sources/wireplumber/ fork is preserved as a historical reference
but no longer used by the build system. A follow-up commit will remove
it after we verify a clean rebuild from upstream git + patch.
Implements the 10 protocol surfaces from Phase 4 of CONSOLE-TO-KDE-DESKTOP-PLAN.md:
- xdg-shell: xdg_wm_base, xdg_surface, xdg_toplevel, xdg_popup, xdg_positioner
- xdg-output (zxdg_output_manager_v1)
- xdg-decoration (zxdg_decoration_manager_v1)
- wp_viewporter for surface scaling
- zwp_linux_dmabuf_v1 for hardware buffer import
- wl_data_device, wl_data_source, wl_data_offer for clipboard/drag-and-drop
- wl_subcompositor, wl_subsurface for sub-surface composition
All protocols are required for Qt6 / KDE Plasma / KWin clients to run under
redbear-compositor. The compositor still serves the greeter only; KWin is
the canonical compositor for the user session.
Captures the QEMU boot of the redbear-full target after the
VIRTIO_BLK_F_RO read-only fix landed in local/sources/base (commit
cffacf591 virtio-blkd: handle read-only drives gracefully). The
boot now proceeds past the previously-fatal virtio-blkd
assert_eq!(*status, 0) abort and continues through the rest of
the desktop init path, validating the fix end-to-end on the
desktop target.
The pre-fix pair is committed in the previous commit; keeping
pre/post pairs adjacent in main-repo history makes the regression
test reproducible from git alone without having to look up
when each log was captured.
Captured log: 16 893 bytes, 204 lines, same scope as the
pre-fix capture (q35 + OVMF, KVM, virtio-blk readonly ISO).
Marked-up analysis: REDBEAR-FULL-BOOT-POST-VIRTIO-BLKD-FIX-RESULTS.md
documents which init stages now reach the login prompt, which
drivers register, and what the next blocking stage is.
Captures the 300s extended QEMU boot of the redbear-full target
that exposed the virtio-blkd read-only assert. Boot progressed
through:
* PCI enumeration, pcid-spawner bring-up
* nvmed multi-queue registration
* virtio-blkd bring-up (READONLY boot ISO attached)
* ahcid probe
then panicked inside virtio-blkd during a write to the boot
drive. The ISO is attached with readonly=on (per the launcher
contract to protect the build artifact), and the driver received
VIRTIO_BLK_S_IOERR (status = 1) on what it expected to be a
writable block device; the assert_eq!(*status, 0) on line 70 of
drivers/storage/virtio-blkd/src/scheme.rs aborted the daemon.
The kernel caught the user-space invalid-opcode fault from the
aborted daemon and reported UNHANDLED EXCEPTION, CPU #0, PID 19
on the virtio-blkd scheme. Captured log is 16 893 bytes / 204
lines; the marked-up analysis (REDBEAR-FULL-BOOT-EXTENDED-RESULTS.md)
identifies the root cause and the missing VIRTIO_BLK_F_RO feature
negotiation that the follow-up commit in local/sources/base adds.
These two files are the only stable record of the pre-fix
behaviour; without them the regression test for the read-only
fix has no baseline. Both files are markdown + plain serial
console capture (no binary artifacts) and are safe to commit.
The post-fix pair (REDBEAR-FULL-BOOT-POST-VIRTIO-BLKD-FIX-RESULTS.md
+ redbear-full-boot-post-virtio-blkd-fix-20260609-181340.log)
are intentionally split into a separate commit so the pre- and
post-fix captures stay paired to their corresponding source
changes.
Adds a single canonical QEMU launcher for the redbear-full desktop
target so subsequent validation runs (boot logs, init probes,
DRM/KMS registration, audio-stack bring-up, D-Bus system bus) can
be reproduced from a single script.
Coverage:
* ACPI / GPE / Notify plumbing (acpid + kernel AML interpreter)
* v6.0 input architecture (evdevd + virtio-keyboard / virtio-mouse)
* MSI-X USB (xhcid via virtio xhci passthrough) and EHCI fallback
* multi-queue NVMe (nvmed with multiple queues)
* virtio-gpu (redox-drm via /scheme/drm/card0, opt-in via --with-gpu)
* virtio-net (e1000d / virtio-netd via net0 user-mode networking)
* D-Bus system bus (dbus) and redbear-sessiond
* SDDM + KWin Wayland compositor (when redbear-full image exists)
The launcher mirrors the per-target test-*qemu.sh scripts already
in this directory (test-ps2-qemu.sh, test-greeter-qemu.sh,
test-phase4-wayland-qemu.sh) so behaviour is consistent:
q35 + OVMF, KVM opportunistic with TCG fallback, serial log to
local/docs/boot-logs/ with a timestamped filename, snapshot=on
when booting the live ISO so the build artifact is not corrupted
across re-runs.
The QEMU display is intentionally hidden (no -display gtk/vnc);
the boot log is the source of truth, not a UI surface. This
matches the v6.0 2026 NO VESA POLICY: the standard display path
is /scheme/drm/card0 via redox-drm, and the test harness never
opens /scheme/display.vesa/.
Exit code 0 on capture, exit code 1 on missing prerequisites
(firmware, qemu, image); boot outcome is in the log, not the
exit code. The 60s default timeout mirrors the redbear-mini
boot time observed in test-ps2-qemu.sh / test-timer-qemu.sh and
can be overridden with --timeout.
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 = '...'.
Add the QEMU boot test results captured on 2026-06-09 from
test-redbear-full-qemu.sh. Two terminal captures (75 s and a longer
~2-min run) accompany the analysis document. The captures and the
analysis document the boot chain for the redbear-full target on
QEMU virtio-gpu, including the relationship to the redbear-mini
reference log.
The blanket reading from commit 5396e6c3c would have forced every direct
edit to mesa, wayland, qt, KF6, KWin, SDDM, llvm, libdrm, redox-drm,
libepoxy, and similar multi-million-line external projects to live
inside recipes/<pkg>/source/, where a 'make clean' or upstream sync
would silently clobber our work. That is not a full fork, that is a
liability.
Replace the single hard prohibition with a two-rule model:
Rule 1 — In-tree Red Bear components (kernel, relibc, base, installer,
bootloader) and small Red Bear-initiated packages: NO overlay, NO
local fork of mainline. Direct edits in recipes/<pkg>/source/ and
recipes/<pkg>/recipe.toml. No symlinks, no patch files.
Rule 2 — Big external projects (mesa, wayland, qt, KF6, KWin, SDDM,
llvm, libdrm, redox-drm, libepoxy, etc.): Red Bear fork at
local/sources/<component>/ is mandatory. The mainline recipe points
at the fork via 'git = ...' or a 'Local' source type. We own the
source, the recipe just builds it.
Both AGENTS.md (top-level) and local/AGENTS.md updated. Cross-references
to the section name in the anti-pattern tables at the bottom of the
policy remain valid.
Add the Red Bear OS forks of libxkbcommon and xkeyboard-config under
local/recipes/, replacing the previous WIP overlays. The local recipes
build against the XKB data and ship meson flags consistent with the
WIP-recipe baseline. The recipes/wip/ symlinks are kept so existing
config/ includes that reference the WIP path keep working.
Red Bear is a full fork. The canonical recipe for a Red Bear
package lives in local/recipes/<category>/<pkg>/, NOT in
recipes/<category>/<pkg>/. The recipes/ tree is a frozen snapshot
that will eventually be deleted.
Previously the cookbook only walked recipes/, so local/recipes/
recipes were unreachable unless apply-patches.sh created a
symlink in recipes/. That overlay approach was wrong (per the
NO OVERLAY-STYLE PATCHES policy in AGENTS.md).
This change makes the cookbook walk ['local/recipes', 'recipes']
in that order. When a package exists in both trees, the
local/recipes/ path ALWAYS wins. The conflict resolution in
the walker is updated to enforce this rule explicitly.
Result: local/recipes/<pkg>/recipe.toml is discovered directly,
no symlink needed. 'repo find <pkg>' returns the local path.
'repo cook <pkg>' uses the local recipe.
This makes the full-fork model work end-to-end. local/recipes/
no longer needs an apply-patches.sh symlink; the cookbook
discovers it natively.
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.
Red Bear is a full fork, not an overlay. Document explicitly:
- What the policy is
- What the forbidden anti-patterns are (apply-patches.sh symlinks,
recipes/*/source/ symlinks, mixing local/recipes/ edits with
recipes/ patches, etc.)
- How to fork a Redox package correctly (copy to local/recipes/,
edit there, delete the upstream recipe)
- Why this matters (auditability, build determinism, no stolen
upstream changes, CI reproducibility)
- Historical context of why apply-patches.sh and local/patches/
still exist (transitional remnants, historical-only)
Also update the 'How the build system works' diagram to clarify
that the source/ symlink is for core Red Bear forks (kernel,
base, relibc, bootloader, installer) — NOT for recipes. Recipes
have a different model: either fork entirely in local/recipes/ or
coexist in mainline. No symlinks, no overlay.
Also add a row to the 'Common anti-patterns' table listing the four
specific overlay-style mistakes (apply-patches.sh, recipes/ symlinks,
local/recipes/ + recipes/ mix, etc.) so future agents see them
flagged next to the existing 'don't edit source/' and 'don't add
patches' rules.
The user's 'IF YOU DID PATCHES, REDO ALL' was triggered by my adding
mesa to apply-patches.sh. The 450k line deletion was the cost of
the overlay approach breaking. This commit prevents recurrence.
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.
Pick up the llvm21 fork's 0.2.3 branch HEAD (1737762446), which
removes the libfbsdvmcore-hacks and lldb-minimize-processes
patches under lldb/test/API/functionalities/postmortem/FreeBSDKernel/tools.
Those are upstream CI patches for LLDB's FreeBSD kernel core-dump
testing infrastructure; they are not part of the upstream test
suite, are not applied anywhere in the build, and are not used
by Red Bear. Removing them keeps the source tree in sync with
what LLDB actually needs to build and prevents future code search
from surfacing them as in-flight Red Bear work.
Pick up the ninja-build fork's 0.2.3 branch HEAD (26f6155), which
adds an extern "C" declaration of getloadavg(double[], int)
guarded by __redox__ to util.cc. Redox's <cstdlib> wrapper pulls
in a stale toolchain stdlib.h that lacks getloadavg, so util.cc
fails to compile on Redox with an implicit-function-declaration
error even though relibc provides the implementation. Other
platforms are untouched.
Pick up the uutils-tar fork's 0.2.3 branch HEAD (bcf6fdb), which
pins rust-version to 1.92.0 to match the Red Bear cross-toolchain
(upstream bumped to 1.94, which is unavailable here) and removes
the uutests dev-dependency, which is a workspace member only
resolvable inside the uutils/coreutils monorepo. With uutests
gone, both root and fuzz Cargo.lock files no longer carry those
workspace-only entries and the lockfiles shrink back to a clean
standalone build.
Pick up the sddm fork's 0.2.3 branch HEAD (a994435), which builds
SDDM as a Wayland-only greeter/daemon for Redox. Highlights:
-DNO_X11 is added globally so X11 code paths are compiled out;
the XAU/XCB/XKB find_package calls are switched to QUIET so
missing X11 dev packages on a Wayland-only build do not fail
configure. XAuth.cpp, XorgDisplayServer.cpp,
XorgUserDisplayServer, and XcbKeyboardBackend sources are
dropped from the daemon, greeter, and helper link lists, the
sddm-helper-start-x11user target is removed, the .ts -> .qm
translation step is dropped (LinguistTools no longer required),
and the test/ subdir is no longer built. UserSession replaces
the Xauthority cookie write with a no-op (Wayland-only) and
passes an explicit third argument to TIOCSCTTY. Note: the
preprocessor guards in Display.cpp / Greeter.cpp / Seat.cpp /
KeyboardModel.cpp are emitted as deeply-nested duplicate
#ifndef NO_X11 blocks; the guards are semantically equivalent
to a single pair per region but should be collapsed in a
follow-up cleanup.
Pick up the installer fork's 0.2.3 branch HEAD (b85f274), which
comments out the optional ext4-blockdev path dependency. The crate
is resolved via a relative path that traverses the local/recipes
symlink chain, which breaks path resolution on Red Bear. The
installer already talks to ext4 through the rsext4 crate, so the
optional path dep is unused. Cargo.lock is rolled forward so the
transitive windows-sys entries match the rest of the resolver
graph for this snapshot.
