P46 migrated ac97d to pci_allocate_interrupt_vector but missed
adding to the pcid_handle parameter. This caused build
failure: cannot borrow pcid_handle as mutable.
Re-implements work that was lost due to ephemeral source/ subdirectory.
ITR dynamically adjusts interrupt coalescing based on packet rate.
- Add ITR register (0xC4) and set_itr() to device.rs
- Add itr.rs tracker with hysteresis-based rate adaptation
- Wire tracker into IRQ handler in main.rs
- Document in AGENTS.md: source/ is ALWAYS rewritten
- drivers/acpid/src/cstate.rs: Evaluate _CST per processor, parse
Package-of-Packages into CStateInfo structs
- AcpiContext: add cstate_state field with refresh, add processor_names()
to scan _PR namespace
- acpid scheme: expose /scheme/acpi/cstates/<proc> read handles
- thermald: read /scheme/sys/cstate, set /scheme/sys/cstate_policy
to restrict to C1 when temp exceeds WARNING_TEMP
Works with kernel P25 cpuidle deep C-states.
Detect CPU vendor by probing MSRs (Intel IA32_THERM_STATUS vs AMD
TCTL MSR C0010293). Support both Intel Tjmax-based and AMD direct
temperature reading. Log detected vendor per CPU at startup.
Extend logd output thread to write logs to per-service files in
/var/log/<service>.log, with automatic size-based rotation (10 MB
threshold, 5 backup files). All logs also go to /var/log/system.log.
Backwards compatible with existing sink file descriptors.
Add RateLimitedLog to common::logger for per-message rate limiting with
"last message repeated N times" warnings. Add structured_log! macro for
key=value formatted logs. Update thermald to rate-limit the max-temp
summary line (30s interval) to reduce log volume.
Track the target CPU ID in InterruptVector, and log the interrupt type
(MSI-X/MSI/Legacy) and CPU affinity at allocation time in
pci_allocate_interrupt_vector. Add log_affinity() helper for drivers
to call after setup.
Add fan.rs module to acpid that discovers FAN* devices under \_TZ,
evaluates _FST for current speed level and RPM, and exposes them via
/scheme/acpi/fan/<name>/status. Update thermald to read and log fan
status alongside temperature sensors.
Replace the old hardcoded /scheme/acpi/thermal_zone/{n} paths with
proper discovery of /scheme/acpi/thermal/ zones and /scheme/coretemp/
CPU temperatures. Logs per-zone and per-CPU temps with max tracking.
Switch network drivers from legacy INTx to pci_allocate_interrupt_vector
which auto-prefers MSI-X > MSI > Legacy. rtl8139d and rtl8168d already
used this helper; e1000d and ixgbed were the remaining legacy-only NIC
drivers.
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
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.
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.
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.
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.
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.
- 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
- 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
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.
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.
Consolidate ~30 absorbed base patches into surviving carriers. Add
new init service files, driver sources, and network/storage modules
for the base recipe. Move absorbed patches to local/patches/base/absorbed/.
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.
