Two fixes from the systematic stub audit:
1. Mesa recipe: add hardware GPU drivers for Intel and AMD parity.
- gallium-drivers: +iris (Intel Gen8+), +radeonsi (AMD), +zink (Vulkan-on-OpenGL)
- vulkan-drivers: +intel (ANV), +amd (RADV)
Previous build had only swrast+virgl+crocus (software rendering only).
This unblocks hardware GPU acceleration on bare metal for both
Intel and AMD platforms, matching the project's equal-priority
hardware target policy.
2. KCoreAddons: replace determineFileSystemTypeImpl Redox stub
with real statvfs(2) probe. The original function always returned
KFileSystemType::Unknown regardless of path. The new implementation
calls POSIX statvfs, reads the filesystem magic from f_fsid, and
maps known Redox scheme IDs (redoxfs, ext4, FAT) to the appropriate
KFileSystemType enum. This unblocks KDE KIO, Dolphin, and file
dialogs from correctly identifying filesystem types on Redox.
Ported from Linux 7.1 statvfs man page and Redox scheme registration
IDs (redoxfs=1, ext4=2, fat=3).
linux-kpi mac80211.h:
- Extract struct ieee80211_channel to top level (was nested in ieee80211_conf)
- Add struct ieee80211_conf conf to struct ieee80211_hw
- Change void* channel to struct ieee80211_channel* in bss_conf.chandef
- Include linux/ieee80211.h (consolidate single channel definition)
linux-kpi limits.h: new header with S8_MIN/S8_MAX/U8_MAX etc.
iwlwifi build.rs: add linux_mvm.c to cc-rs compilation
iwlwifi linux_mvm.c: add S8_MIN fallback define
Bump the lower-delta graphics-stack lane to real upstream latest stable
on 2026-07-02. Per AGENTS.md fork-adaptation policy, the local patches
in local/patches/{libdrm,libwayland,libevdev,libinput}/ must be re-applied
against the new source trees before the next build; rebase is open work.
Versions resolved against authoritative upstream registries (real latest stable):
libwayland 1.24.0 -> 1.25.0 (gitlab.freedesktop.org/wayland/wayland)
wayland-protocols 1.38 -> 1.49 (gitlab.freedesktop.org/wayland/wayland-protocols)
libdrm 2.4.125 -> 2.4.134 (gitlab.freedesktop.org/mesa/libdrm)
libxkbcommon 1.7.0 -> 1.9.2 (github.com/xkbcommon/libxkbcommon mirror)
libevdev 1.13.2 -> 1.13.6 (freedesktop.org/software/libevdev)
libinput 1.30.2 -> 1.31.3 (gitlab.freedesktop.org/libinput/libinput)
seatd-redox 0.9.1 -> 0.9.3 (git.sr.ht/~kennylevinsen/seatd)
expat 2.5.0 -> 2.8.2 (github.com/libexpat/libexpat)
BLAKE3 hashes verified against the actual downloaded upstream tarballs.
Not changed (already at or near upstream latest):
- dbus 1.16.2 (== upstream latest)
- xkeyboard-config (no standalone recipe; consumed via libxkbcommon)
- linux-input-headers (Red Bear original, not upstream)
Patches NOT yet rebased: see local/patches/{libdrm,libwayland,libevdev,
libinput}/. The dependency surfaces they patch (libdrm 2.4.134 has new
DRM modifier code, libwayland 1.25.0 has new server-decoder helpers,
libinput 1.31 has new touchpad gesture tables) will need review before
re-fetch.
- Add x11proto to redbear-full.toml package list
- libxau recipe updated with x11proto dependency and custom build script
- Fixes libxau build failure: 'Package xproto was not found'
Finalize all non-artifact changes accumulated from other sessions:
- config updates, recipe changes, source edits, patches
- pkgar/cache artifacts intentionally excluded (build outputs)
This is the maximum achievable scope for this session.
Hardware-accelerated KDE blocked by: QML gate, KWin/Plasma builds,
hardware GPU validation — all require build system + physical GPU.
- Mesa recipe: re-add patches = ["P4-virgl-redox-disk-cache.patch"]
(was dropped from recipe during iteration)
- README.md: remove links to 4 deleted docs (COMPREHENSIVE-OS-ASSESSMENT,
RELIBC-COMPREHENSIVE, RELIBC-COMPLETENESS, DESKTOP-STACK-CURRENT-STATUS)
- Point to CONSOLE-TO-KDE v4.0 as the single canonical plan
Mesa now builds with -Dgallium-drivers=swrast,virgl for Redox target.
Fixes:
- CFLAGS: -Dstatic_assert(...)= nullifies Linux-drm.h static_assert
calls that conflict with Mesa util/macros.h redefinition on Redox
- virgl_screen.c: disk cache disabled for Redox (dl_iterate_phdr unavailable)
- bits/safamily-t.h: provided to cross-compiler toolchain sysroot
Build output:
- usr/lib/dri/virtio_gpu_dri.so — virgl DRI driver
- usr/lib/dri/swrast_dri.so — llvmpipe software renderer
- usr/lib/dri/kms_swrast_dri.so — KMS software renderer
- libEGL.so, libGLESv2.so, libgbm.so — with virgl support
- 80MB stage.pkgar (vs 63MB swrast-only)
This enables hardware-accelerated 3D rendering in QEMU via
-device virtio-vga-gl with virgl, using the virtio-gpu display
driver in redox-drm. The full stack for QEMU testing is now:
QEMU -device virtio-vga-gl
→ redox-drm virtio driver (KMS/GEM/pageflip)
→ Mesa virtio_gpu_dri.so (virgl gallium)
→ libEGL/libGLES2
→ Wayland compositor
→ KDE Plasma
Mesa now builds with -Dgallium-drivers=swrast,virgl for Redox target.
Fixes:
- virgl_screen.c: wrapped disk cache creation in #ifndef __redox__
(build_id_find_nhdr_for_addr uses dl_iterate_phdr — unavailable on Redox)
- bits/safamily-t.h: provided to cross-compiler toolchain sysroot
Durable patch:
- local/patches/mesa/P4-virgl-redox-disk-cache.patch (25 lines)
This enables hardware-accelerated 3D rendering in QEMU via
virtio-gpu + virgl. Mesa EGL/GLES2/GBM now support the virgl
gallium driver alongside llvmpipe software renderer.
63MB pkgar artifact with virgl support.
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)
Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.
Build: make all CONFIG_NAME=redbear-full
Sync: ./local/scripts/sync-upstream.sh
