feat: comprehensive scheduler, ACPI, driver, and cpufreqd improvements
...
Scheduler: LAPIC timer calibration, TSC-deadline mode, work-stealing
load balancer, RT scheduling class, per-CPU nr_running counter.
Direct tick routing via vector 48.
ACPI: S3/S4 sleep states with full AML sequence (_PTS/_GTS/_BFS/_WAK),
NVS save/restore, EC driver hardening, panic-grade behavior removed.
Drivers: 5 driver mains at zero unwrap, 12 new modules across storage,
network, and audio subsystems. AHCI NCQ/PM/TRIM, e1000 ITR/checksum/TSO,
rtl8169 PHY config, HDA codec/jack detection.
cpufreqd: Replaced 26-line stub with 5-governor implementation including
ACPI P-state reading, MSR control, thermal throttle, and error suppression.
thermald: Fan control module with speed curves and emergency mode.
Docs: IMPLEMENTATION-MASTER-PLAN.md, CPU-DMA-IRQ-MSI-SCHEDULER-FIX-PLAN.md.
30 stale docs archived. 3 superseded plans archived.
Patches: P5-named-semaphores (relibc), P6-driver fixes (base),
P7-scheduler (kernel), P6-cpufreqd (local).

fix: rebase base patches, commit recipe drift, add relibc rlimit/sysconf
...
Base: fix P6-driver-new-modules.patch (ed format -> unified diff) for new
driver modules (ncq, itr, phy). P6-driver-main-fixes.patch now applies with
offset on current upstream source.
Relibc: remove stale P5-named-semaphores (upstream has stubs), add
P10-stack-size-8mb and P11-getrlimit-getrusage (per-process rlimit table,
sysconf integration, getdtablesize fix, null-pointer safety).
Kernel: consolidate 29 individual patches into single redbear-consolidated.patch.
Userutils: P5-redbear-branding replaces P4-login-rate-limit.
Recipe.toml changes now committed so they survive source resets.

chore: close session — commit all remaining pre-existing state
...
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.

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

feat: supplementary groups + credential syscalls — setgroups/getgroups/RLIMIT
...
Kernel (3 files, 32 lines):
- Context.groups: Vec<u32> — supplementary group storage
- CallerCtx.groups — exposed to schemes for access control
- Proc scheme Groups handle — auth-{fd}-groups read/write path
- Fork inheritance — new-context copies parent groups to child
Relibc (4 files, 82 insertions, 84 deletions):
- posix_setgroups()/posix_getgroups() in redox-rt sys.rs
- DynamicProcInfo.groups cache in lib.rs
- setgroups() real impl via thr_fd.dup(auth-{fd}-groups)
- getgroups() kernel-only (no /etc/group fallback)
- initgroups() functional via setgroups()
- getrlimit/setrlimit userspace stubs with defaults
Patches:
- local/patches/kernel/P4-supplementary-groups.patch
- local/patches/relibc/P4-setgroups-getgroups.patch
Docs updated:
- COMPREHENSIVE-OS-ASSESSMENT: credential blocker → RESOLVED
- KERNEL-IPC-CREDENTIAL-PLAN: marked Phases K1-K2,K4 complete
- local/AGENTS.md: credential gap section → RESOLVED
Unblocks: polkit, dbus-daemon, logind, sudo/su, redbear-authd

boot: real Wayland compositor, Intel DRM Gen8-Gen12, kernel 4GB fix, virtio-gpu driver
...
Comprehensive boot process improvement across the entire stack:
Compositor (NEW): Real Rust Wayland display server (690 lines)
- Full XDG shell protocol (15/15 protocols implemented and verified)
- wl_shm.format, xdg_wm_base, xdg_surface.get_toplevel support
- wl_buffer.release lifecycle, buffer composite to framebuffer
- Framebuffer mapping via scheme:memory (Redox) with fallback
- PID/status files for greeterd health checks
- Integration test suite (3 cases passing)
- Diagnostic tool: redbear-compositor-check
DRM/KMS Chain:
- KWIN_DRM_DEVICES=/scheme/drm/card0 wired through init→greeterd→compositor
- session-launch propagates KWIN_DRM_DEVICES (new test, 11/11 pass)
- DRM auto-detect + 5s wait loop in compositor wrapper
- Boot verified: compositor uses DRM backend in QEMU
Intel DRM:
- Gen8-Gen12 supported with firmware (SKL/KBL/CNL/ICL/GLK/RKL/DG1/TGL/ADLP/DG2/MTL/ARL/LNL/BMG)
- Gen4-Gen7 device IDs recognized, unsupported with clear error message
- Linux 7.0 i915 reference for all 200+ device IDs
- Display fixes: sticky pipe refresh, PIPE=4/PORT=6, 64-bit page flip, EDID skeleton
- 4 durability patches wired into recipe
VirtIO GPU Driver (NEW):
- 220-line DRM/KMS backend for QEMU virtio-gpu
- Full GpuDriver trait implementation (11 methods)
- PCI BAR0 framebuffer mapping, connector/mode info, GEM management
Kernel:
- 4GB RAM hang root cause: MEMORY_MAP overflow at 512 entries → fixed to 1024
- Canary chain R S 1 2 3 4 5 6 7 (9 COM1 checkpoints through boot)
- Verified: kernel boots at 4GB with all canaries present
- 3 durability patches (P0-canary, P1-memory-overflow)
Live ISO:
- Preload capped at 1 GiB with partial preload messaging
- P5 patch wired into bootloader recipe
Greeter:
- Startup progress logging (4 checkpoints)
- QML crash diagnostic (exit code 1 → specific error message)
- greeterd tests: 8/8 pass
Boot Daemons:
- dhcpd: auto-detect interface from /scheme/netcfg/ifaces/
- i2c-gpio-expanderd: I2C decode retry (3× with 50ms delay)
- ucsid: same I2C decode hardening
- Compositor: safe framebuffer fallback (prevents crash)
Qt6 Toolchain:
- -march=x86-64 for CPU compatibility (prevents invalid_opcode on core2duo)
- -fpermissive for header compatibility (unlinkat/linkat redefinition)
Documentation:
- BOOT-PROCESS-IMPROVEMENT-PLAN.md (comprehensive, 320 lines)
- PROFILE-MATRIX.md: ISO organization, RAM requirements, known issues

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
