vasilito bb4f757ba0 kernel: Add MONITOR/MWAIT C1 idle support (P24) 
Implement CPU power-saving idle loop using x86 MONITOR/MWAIT:
- Add monitor(), mwait(), enable_and_mwait() to interrupt module
- Detect MWAIT availability via CPUID at boot
- Use MONITOR+MWAIT instead of STI+HLT when supported
- Expose /scheme/sys/cstate_policy for userspace control
- Add RdWr Kind variant to sys scheme for read+write files

vasilito 56be23ce6e kernel: Add sys:msr scheme for userspace MSR read/write 
Expose MSR access via /scheme/sys/msr/<cpu>/<msr> for root only.
Required for cpufreqd P-state control and thermal sensor drivers.

vasilito 9233726f58 P0..P71 baseline before fbcond/fbbootlogd init fix 2026-05-20 00:30:18 +03:00
vasilito ba5e010bb7 P21-P23: boot daemon panic fixes, x2APIC MADT fallback, rootfs hard dep on drivers 
P21: Replace 67 panic-grade calls across 9 boot daemon files with
graceful error handling. Affected: ps2d, inputd, fbcond, fbbootlogd.

P22: Add x2APIC MADT fallback for processors with LocalApic entries
instead of LocalX2Apic entries. QEMU KVM boots now correctly detect
all vCPUs via zero-extended APIC ID fallback.

P23: Change 50_rootfs.service from requires_weak to requires on
40_drivers.target, ensuring redoxfs waits for disk drivers before
attempting filesystem mount. This fixes the boot race where rootfs
mount failed before drivers were ready, causing init to have no
userland services after switchroot.

vasilito ecc120b013 chore: kernel source patches, local recipe updates, and build artifacts 
Kernel source (ephemeral — changes durable in local/patches/kernel/):
- P20 x2apic ICR mode fix, P21 x2apic SMP fix applied
- ACPI MADT, RSDP, SDT improvements
- Context switch, percpu, event, IRQ scheme updates
- MSI/vector allocation, NUMA/SLIT/SRAT support

Local recipe source updates:
- redox-driver-acpi: bus/prt hardening
- redox-drm: Intel display, KMS connector improvements
- driver-manager: config/scheme hardening
- thermald: main.rs fix
- uutils-tar, ninja-build: source updates

Other:

vasilito f6c2eb2a8e feat: ACPI Wave 1 boot-critical hardening (P19) + robust patch generation 
- P19-init-startup-hardening: Replace panic-grade expect/unwrap in init
  startup paths (getns, register_scheme_to_ns, setrens, filename parsing)
  with graceful error handling and logging
- P19-acpid-startup-hardening: Replace panic-grade calls in acpid with
  graceful degradation (rxsdt read failure → warn + exit 0, SDT parse →
  error + exit 1, I/O privilege → fatal, scheme registration → fatal,
  setrens → warn + continue, event loop errors → log + continue)
- P18-9-msi-allocation-resilience: Regenerate with git diff -U0 -w format
  for maximum context resilience
- fetch.rs: Change --fuzz=0 to --fuzz=3 for resilient patch application
- AGENTS.md: Document robust patch generation technique as mandatory
- Add P4/P5/P6/P7 patches (estale, dmi, i2c, ps2d hardening)
- Add P21 kernel x2apic SMP fix patch
- Multiple local recipe source improvements (redox-drm, driver-manager,
  driver-acpi, thermald)
- Config updates for redbear-mini and redbear-device-services
- Subsystem assessment document

vasilito 7798ed86eb fix: remove P20 forward patch — cascading context issues with P16-1 
x2APIC ICR mode fix cannot be a forward patch because P16-1-sipi-timing
references the ICR line as context. Modifying P1 (which introduces the line)
would require updating P16-1's offsets. Will address by consolidating into
an existing early patch in a future revision.

vasilito 2bfe4b427b feat: raw framebuffer fallback for fbbootlogd when DRM unavailable 
- Add RawFb struct: direct framebuffer rendering via physmap
- Add RawTextScreen: simple text renderer using orbclient font
- Fallback in FbbootlogScheme::new() when V2GraphicsHandle fails
- Reads FRAMEBUFFER_ADDR/WIDTH/HEIGHT/STRIDE from bootloader env
- Scroll via ptr::copy on pixel rows, clear bottom line
- No DRM, no shadow buffer, no GPU required — like MS-DOS text mode
- Add common dependency to fbbootlogd Cargo.toml

vasilito 081ed10a8b fix: x2APIC ICR format + build system durability docs 
- Fix LocalX2Apic handler: use local_apic.x2 to select correct ICR
  format (<<32 for x2APIC, <<56 for xAPIC) instead of hardcoded <<32
- Promote x2APIC/xAPIC detection from debug! to info! for bootlog
- Document build system durability in AGENTS.md: cardinal rule,
  two-layer architecture, correct workflow, anti-patterns
 2026-05-17 13:57:37 +03:00
vasilito cee25393d8 fix: boot process improvements — dependency cycle, INIT_NOTIFY, probing loop, and log spam fixes 
- Fix P15-8-init-cycle-detection.patch: replace visiting+error with seen+silent-skip
  to eliminate 11 false-positive 'dependency cycle detected' errors on shared deps
- Fix P0-daemon-fix-init-notify-unwrap.patch: remove eprintln! for missing
  INIT_NOTIFY (expected for oneshot_async services, ~7 daemons affected)
- Fix driver-manager hotplug loop: add PERMANENTLY_SKIPPED static set shared
  between hotplug handler and DriverConfig::probe() to stop infinite re-probing
  of Fatal/NotSupported/deferred-exhausted device+driver pairs (e.g. ided)
- Fix driver-manager log_timeline: suppress repeated EPIPE/ENOENT errors with
  AtomicI32 dedup and AtomicBool one-shot guards for boot timeline JSON
- Add driver-manager SIGTERM handler, ACPI bus registration, --status mode,
  driver reap loop, graceful shutdown, and reduced deferred retries (30→3)

vasilito ff4ff35918 feat: track all source trees in git — full fork offline-first model 
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.

Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.

127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.

vasilito dc59144946 fix: kernel rebrand patch — correct post-consolidated context for fuzz=0 
Generated from clean 866dfad0 + consolidated.patch state via diff.
Two hunks for x86_64: comment on line 87 and info! on line 110.
aarch64 (line 94) and riscv64 (line 100) — one hunk each.
Verified: patch applies with --fuzz=0 on top of redbear-consolidated.

vasilito 2e6592a7d1 docs: QEMU desktop boot evidence — virtio-gpu works, login prompt reached 
redbear-full (4GB) boots in QEMU with virtio-gpu-pci:
  - virtio-gpu detected: display 0 (1280x800px) ✅
  - framebuffer console: 'RedBear Login:' prompt appears ✅
  - Wayland compositor: fails on /dev/fd/63 (bash process substitution
    not supported on Redox) — documented as blocker in plan
  - D-Bus system bus: session broker registered ✅
  - KDE session assembly helper: started ✅
  - iommu: no AMD-Vi units in QEMU (expected) ✅

CONSOLE-TO-KDE-DESKTOP-PLAN.md v4.1:
  - Updated compositor blocker: /dev/fd missing on Redox
  - Added QEMU boot evidence date and details
  - Removed P2-rebrand from kernel recipe (line-number conflict
    with consolidated patch — needs rebase)

Remaining errors (pre-existing):
  - fbcond: 'No display present yet' (timing, self-recovers)
  - procmgr: SIGCHLD to PID 1 not permitted
  - cpufreqd: MSR write fails (QEMU, expected)
  - keymapd: Bad file number on scheme read

vasilito 3dee740906 feat: build system hardening — unwired patch detector + rebrand 
check-unwired-patches.sh: scans local/patches/ for .patch files not
referenced in any recipe.toml patches = [...] array. Detects 262
unwired patches (most intentionally kept for reference/rebase).

P2-rebrand-start-message.patch: minimal 39-line patch changing
'Redox OS starting' to 'RedBear OS starting' in x86_64, aarch64,
and riscv64 arch start files. Wired into kernel recipe after
P8-msi.patch. Verified: make r.kernel builds with all 3 patches.

Build system issues surfaced by the detector:
- 250+ kernel individual patches kept for reference (absorbed/)
- ~50 base individual patches — many intentionally unwired
- ~30 relibc patches — may need wiring into relibc recipe
- build-system patches applied by scripts, not recipes

vasilito bd1a5320d5 fix: remove P7-scheduler-improvements from kernel recipe patches 
P7 failed 3/4 hunks on context.rs at kernel rev 866dfad0.
Consolidated patch already includes P5-sched-rt-policy, P5-context-mod-sched,
P6-percpu-runqueues, P6-futex-sharding which cover most scheduler improvements.
P7 needs rebase — documented in recipe comment.

Verified: full 'make r.kernel' fetch+patch+build chain works:
  git clone + consolidated.patch + P8-msi.patch + cargo build → 1.5MB kernel

vasilito d1c04f2651 feat: T1.1-T2.2 MSI subsystem — kernel MSI, vectors, affinity, validation 
Kernel:
- T1.1 msi.rs: MSI message composition (MsiMessage), validation
  (is_valid_msi_address, is_valid_msi_vector), capability parsing
  (MsiCapability, MsixCapability) with bounds-safe .get() access
- T1.2 vector.rs: per-CPU bitmatrix vector allocation/deallocation
- T1.3 IRQ scheme: MSI vector validation gate at irq_trigger,
  iommu_validate_msi_irq hook, msi_vector_is_valid helper
- mod.rs: declarations for msi + vector modules
- Fix validation mask 0xFEEF_F000→0xFFF0_0000 (bits 31:20 check)

T2.1 driver-sys: program_x86_message kernel-mediated validation
- Validates MSI address range 0xFEE0_0000–0xFEEF_EFFF and vector 32–254
- Gated behind #[cfg(target_os = "redox")]; clearly rejects non-Redox
- Uses correct 0xFFF0_0000 mask for destination-ID-tolerant validation

T2.2 kernel-side affinity: Handle::IrqAffinity variant
- kopenat handles <irq>/affinity and cpu-XX/<irq>/affinity paths
- kwrite validates CPU id exists, stores mask atomically
- kfstat/kfpath/kreadoff/close all handle new variant
- Fix unused handle_irq warning in kwrite match arm

T2.3 driver-sys: MsiAllocation struct + irq_set_affinity helper
- MsiAllocation with round-robin CPU allocation via alloc_cpu_id
- irq_set_affinity uses scheme:irq/<irq>/affinity write path
- IrqFd type alias in pci.rs for file descriptor tracking

IOMMU T3.1: InterruptRemapTable, IRTE encode/decode, IrqRemapManager
- IRTE (16-byte) encoding/decoding for AMD-Vi interrupt remapping
- InterruptRemapTable with program/invalidate/find_free
- IrqRemapManager with multi-table remap and validate_msi gate
- Remove arbitrary .min(256) bound on find_free

P8-msi.patch: 281-line durable kernel patch, wired in recipe.toml
 2026-05-04 18:00:15 +01:00

 2026-05-04 11:57:48 +01:00
vasilito 7f2bf081c5 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.
