vasilito b1af8a356f acpid: Add ACPI thermal zone discovery and evaluation (P44)
Implement full thermal zone backend in acpid:
- thermal.rs: Discover \_TZ_.TZ* zones, evaluate \_TMP, \_CRT, \_PSV,
  \_AC0, \_TC1, \_TC2, \_TSP, \_TZP methods
- scheme.rs: Expose /scheme/acpi/thermal/ with per-zone temperature files
- acpi.rs: Add thermal_state and thermal_zone_names() to AcpiContext

Wired as P44 patch in base recipe.toml.

vasilito 2a5eff93ec P24: ACPI S5 derivation with shutdown semantics and error propagation
Add deterministic S5 (soft-off) state derivation and structured error
handling to acpid. Derive S5 parameters once at startup (or retry at
shutdown if AML was not ready) instead of re-parsing the _S5 package
on every shutdown attempt. Replace unit-return set_global_s_state()
with ShutdownResult enum for proper error propagation and fallback
handling.

Changes:
- S5State struct caches SLP_TYPa/b, PM1a/b ports, derivation timestamp
- ShutdownError enum: MissingFadt, Pm1aZero, AmlNotReady, S5NotFound,
  S5NotPackage, SlpTypNotInteger, S5WriteFailed
- ShutdownResult enum: Ok, FallbackReset, Err(ShutdownError)
- derive_s5_state() method with early init attempt and lazy fallback
- set_global_s_state() returns ShutdownResult instead of ()
- Early S5 derivation in AcpiContext::init() logs AML readiness status
- main.rs logs shutdown result for debugging

This is W2.1/W2.2 from ACPI-IMPROVEMENT-PLAN.md.

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 b1022dfa39 fix: ramfs depends hard on randd before startup (P20)
ramfs@.service required randd as requires_weak, which doesn't enforce
readiness ordering. When ramfs called std::random before randd registered
/scheme/rand, it panicked with 'failed to generate random data'.

Changed requires_weak to requires so init waits for randd to register
its scheme before starting ramfs.

Also patched Rust stdlib sys/random/redox.rs to fall back to xorshift64
seeded from ASLR rather than panicking when /scheme/rand is unavailable.
This is a belt-and-suspenders fix: even with proper ordering, the stdlib
should not panic on missing entropy during early boot.

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 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 13c5d239ca feat: add Mesa EGL hardware GPU probe with virgl support
P5: Enable PRIME export for GBM dumb buffers so virgl can import scanout\nbuffers via fd-to-handle.

P6: Add redox_probe_device_hw() that opens /scheme/drm/card0, resolves the\nDRI driver via PCI ID lookup (loader_get_driver_for_fd), and initializes the\nhardware path through dri2_load_driver_dri3 with __DRIimageLoaderExtension.\nIncludes fprintf(stderr) debug logging tagged [REDOX-EGL] for tracing the\nHW init sequence. Falls back to software rendering if HW probe fails.

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 9b43ddabcf relibc: full eventfd() implementation + no-stubs policy in AGENTS.md
Replaced P3-sys-eventfd-create.patch (constants-only stub) with:
- P3-eventfd-impl.patch: full eventfd() opening /scheme/event/eventfd
- P3-bits-eventfd.patch: eventfd_t type
- P3-eventfd-cbindgen.patch: generates sys/eventfd.h C header
- P3-bits-eventfd-mod.patch: wires bits_eventfd into header/mod.rs

libwayland: removed eventfd stub from redox.patch — relibc provides it now.
Only meson.build fix + wl_proxy null guards + MSG_NOSIGNAL guard remain.

Documented zero-tolerance stub policy at top of local/AGENTS.md.

vasilito 2f700e380e relibc: add stdint.h include to sys/types/internal.h
Fixes C compilation failures where signal.h (via signalfd_siginfo struct)
uses uint32_t/int32_t/uint64_t without stdint.h being transitively included.

The include chain signal.h -> sys/types.h -> sys/types/internal.h lacked
stdint.h, causing 'unknown type name' errors for uint32_t, uint8_t, and
uintptr_t in any C package compiling against the relibc sysroot headers.

Affected: diffutils, libiconv, and all packages whose autoconf checks
included <signal.h> and failed on the missing stdint types.

Added 'stdint.h' to sys_includes in sys_types_internal/cbindgen.toml.
Durable in local/patches/relibc/P3-sys-types-stdint-include.patch.

- compositor: add wl_seat.name + pointer capabilities for Qt6 compat
- greeter: use redox QPA (libqredox.so) instead of broken Qt6 Wayland
- greeter: reduce DRM wait 10s→2s, kded6 offscreen QPA to avoid crash
- thermald: add CPU die temperature via MSR IA32_THERM_STATUS (Linux coretemp)
- pcid: diagnostic MCFG warning with Q35 guidance, address validation
- dhcpd: auto-interface detection (P0-dhcpd-auto-iface.patch wired)
- procmgr: SIGCHLD EPERM→debug (kernel limitation, not a bug)
- ps2d LED: warn→debug on modern hw without real PS/2 controller
- ps2d mouse: 10×1s→3×250ms retry, fast-fail on unknown response
- i2c RON: handle empty response from i2cd when no adapters present

vasilito f65bc145a1 fix: comprehensive boot warnings and exceptions — fixable silenced, unfixable diagnosed
Build system (5 gaps hardened):
- COOKBOOK_OFFLINE defaults to true (fork-mode)
- normalize_patch handles diff -ruN format
- New 'repo validate-patches' command (25/25 relibc patches)
- 14 patched Qt/Wayland/display recipes added to protected list
- relibc archive regenerated with current patch chain

Boot fixes (fixable):
- Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset)
- D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped)
- redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped)
- daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch)
- udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async)
- relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs
- greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait)
- greeter-ui: built and linked (header guard unification, sem_compat stubs removed)
- mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps
- greeter config: removed stale keymapd dependency from display/greeter services
- prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified

Unfixable (diagnosed, upstream):
- i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort
- kded6/greeter-ui: page fault 0x8 — Qt library null deref
- Thread panics fd != -1 — Rust std library on Redox
- DHCP timeout / eth0 MAC — QEMU user-mode networking
- hwrngd/thermald — no hardware RNG/thermal in VM
- live preload allocation — BIOS memory fragmentation, continues on demand

- ~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 5214621ff8 fix: remove P6-e1000d-msi-migration from base patches (conflict)
P6-e1000d-msi-migration.patch conflicts with P6-driver-main-fixes.patch
— both modify e1000d/src/main.rs at overlapping lines. The MSI migration
must be merged into P6-driver-main-fixes during the upcoming P6 rebase.

P6-e1000d-msi-migration.patch preserved in local/patches/base/ for reference.

vasilito e368f56817 feat: e1000d MSI/MSI-X migration — use pci_allocate_interrupt_vector
e1000d was the last NIC driver using legacy IRQ (irq.irq_handle()).
Migrated to pci_allocate_interrupt_vector which tries MSI-X first,
then MSI, then falls back to legacy INTx — matching rtl8168d, rtl8139d,
ihdad, ihdgd, and nvmed.

63-line patch at local/patches/base/P6-e1000d-msi-migration.patch,
symlinked and wired into recipes/core/base/recipe.toml.

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
