vasilito 4c25e00bed fix: restore Mesa patch wire + update README broken doc links 
- 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

vasilito 73877d5a3a feat: Mesa virgl DRI driver builds — virtio_gpu_dri.so (80MB pkgar) 
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

vasilito 2638186ce1 feat: Mesa virgl gallium driver — hardware-accelerated 3D for QEMU 
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.

vasilito 34360e1e4f feat: P0-P6 kernel scheduler + relibc threading comprehensive implementation 
P0-P2: Barrier SMP, sigmask/pthread_kill races, robust mutexes, RT scheduling, POSIX sched API
P3: PerCpuSched struct, per-CPU wiring, work stealing, load balancing, initial placement
P4: 64-shard futex table, REQUEUE, PI futexes (LOCK_PI/UNLOCK_PI/TRYLOCK_PI), robust futexes, vruntime tracking, min-vruntime SCHED_OTHER selection
P5: setpriority/getpriority, pthread_setaffinity_np, pthread_setname_np, pthread_setschedparam (Redox)
P6: Cache-affine scheduling (last_cpu + vruntime bonus), NUMA topology kernel hints + numad userspace daemon

Stability fixes: make_consistent stores 0 (dead TID fix), cond.rs error propagation, SPIN_COUNT adaptive spinning, Sys::open &str fix, PI futex CAS race, proc.rs lock ordering, barrier destroy

Patches: 33 kernel + 58 relibc patches, all tracked in recipes
Docs: KERNEL-SCHEDULER-MULTITHREAD-IMPROVEMENT-PLAN.md updated, SCHEDULER-REVIEW-FINAL.md created
Architecture: NUMA topology parsing stays userspace (numad daemon), kernel stores lightweight NumaTopology hints

vasilito 4cf59376d5 fix: mesa builds — fixed missing backslash + -Wno-error c_args 
mesa recipe had missing backslash breaking meson flags.
Added proper -Dc_args=['-Wno-error=implicit-function-declaration','-Wno-error']
mesa now builds successfully (30-min compile).
Greeter cascade: qtbase pre-existing QPlatformOpenGLContext issue.

vasilito 6746bc44da fix: mesa strcasecmp Werror + Packages/ auto-sync 
mesa: add -Dc_args=-Wno-error=implicit-function-declaration
Packages/: 91 pkgar files committed, sync-packages.sh script
cache-auto: now syncs to Packages/ after build

vasilito 25ddb0f847 fix: libwayland SFD_CLOEXEC + glib meson, suppress cascade packages 
libwayland: check signal.h SIG_BLOCK instead of sys/signalfd.h SFD_CLOEXEC
glib: add -I sysroot/include to meson c_args
redox-drm: remove amdgpu build dep (not needed for boot)
config: suppress curl, git, mc, libinput, KF6 chain (cascade rebuild)

Build succeeds: 4 GiB harddrive.img, boots with compositor.
Greeter blocked on libwayland relibc header gaps (prctl.h etc).

vasilito 908f5a7914 build: glib build fix (suppress impl-func-decl error), suppress curl/git 
- glib: add -Dc_args=-Wno-error=implicit-function-declaration
- curl, git: suppressed from full config (not needed for boot)
- dbus: -Depoll=disabled for relibc compat
- Makefile: cache auto-commit after successful build

vasilito 50b731f1b7 Red Bear OS — microkernel OS in Rust, based on Redox 
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
