vasilito 6d14a378c3 coretempd: disable MSR fallback, use /scheme/sys/cpu exclusively 
Kernel has a use-after-free bug in sys_read triggered by /scheme/sys/msr
access. The probe guard prevents most crashes but the kernel bug can still
trigger during MSR read paths. Removing the MSR fallback eliminates this
crash path entirely. Vendor detection now uses /scheme/sys/cpu only.

vasilito a52632f69d fix: bits_pthread cbindgen needs stddef.h for size_t type 
The generated bits/pthread.h uses size_t but had no includes.
Also added openat cache vars to m4 recipe for gnulib cross-compilation.

vasilito 052be6d264 feat: intelligent platform detection for cpufreqd and coretempd 
cpufreqd:
- Read CPU vendor and frequency from /scheme/sys/cpu (CPUID-based)
- Generate P-states dynamically from detected max/base frequency
- Remove hardcoded 2400-1200 kHz fallback table
- Intel SpeedStep and AMD encoding support

coretempd:
- Detect vendor from /scheme/sys/cpu before MSR probing
- Read CPU count from /scheme/sys/cpu for accuracy
- Fall back to MSR detection only when platform info unavailable

vasilito ad74e920ae fix: coretempd MSR probe for QEMU default machine type 
On QEMU's default i440FX machine type, rdmsr on unsupported MSRs
(0x19c IA32_THERM_STATUS, 0x1a2 IA32_TEMPERATURE_TARGET) causes a
kernel #GP that kills the process. Same pattern as cpufreqd: spawn a
child with --probe-msr to test readability before the main loop. If
probe fails, disable all MSR reads and report all CPUs as Unknown.

vasilito 77795cfa18 fix: redbear-mini boot to login prompt + daemon hardening 
- 29_activate_console.service: oneshot -> oneshot_async (unblocks init
  scheduler, enabling getty 2 -> login)
- 15_coretempd.service: oneshot_async -> {scheme="coretemp"} (init
  now correctly registers the scheme fd)
- cpufreqd: child-process MSR probe detects QEMU's lack of MSR 0x199
  and gracefully degrades to monitoring-only mode
- coretempd: notification failure is now non-fatal (WARN instead of ?)
- driver-manager: "no match entries" downgraded from warn to debug
  (infrastructure daemons intentionally have no hw match)

vasilito cd05afdcb1 initfs: exit after enumeration, skip scheme path checks 
- Skip binary existence check in probe(): Redox scheme paths
  (especially /scheme/initfs/) may block on open/stat indefinitely.
  Command::new() spawn fails cleanly if binary missing.
- In initfs mode: use synchronous probe, do bounded deferred
  retries, then exit. Rootfs instance handles hotplug.
- Avoids pcid config handle read hang that blocks async threads.

vasilito 706050482b fix: rewrite coretempd to use redox_scheme Socket + SchemeSync 
Replaced broken UnixListener::bind(':coretemp') with proper redox_scheme::Socket::create() + SchemeSync trait impl. Event loop uses next_request/handle_sync/write_response pattern. Verified: registers scheme:coretemp, detects CPU info, zero panics.

vasilito 845ae99f9d fix graphical boot: DRM scheme detection, ConsoleKit bypass, boot chain deps 
Three fixes for the KWin DRM device discovery failure:

1. drm_scheme_ready(): replace head -c 1 with exec 3< open test.
   Reading from a DRM scheme fd blocks because the scheme expects
   ioctl-style request/response, not streaming reads. Use open()
   success as the scheme availability probe instead.

2. ConsoleKitSession::create(): return nullptr immediately.
   The D-Bus isServiceRegistered() call can block indefinitely when
   the bus daemon doesn't fully implement org.freedesktop.DBus.
   With both LogindSession and ConsoleKitSession returning nullptr,
   Session::create() falls through to NoopSession which uses plain
   open() for DRM device access.

3. Boot chain deps: redox-drm depends on driver-manager,
   greeter depends on evdevd (keyboard/mouse ready before login).

Also includes: KF6 CMake build fixes, Qt6 platform patches,
libdrm Redox ioctl shim, and wayland.toml scheme check fix.

vasilito ac2f1ccbc2 iommu: Add Intel VT-d daemon foundation (Phase 3.2) 
- Add intel_vtd.rs module with DMAR parsing, DRHD discovery,
  register definitions, and basic unit initialization
- Update iommu daemon discovery to detect both AMD-Vi (IVRS)
  and Intel VT-d (DMAR) units

- Intel VT-d init: version check, capability read, disable
  translation, report supported features (QI, IR, EIM)

Full DMA remapping enablement (root table, context entries,
page tables, command buffer) remains as TODO for follow-up.

  driver-acpi, thermald)
- Config updates for redbear-mini and redbear-device-services
- Subsystem assessment document

  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)

  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)
