The previous fire-and-forget fix passed hwd's own INIT_NOTIFY fd to pcid,
but that fd had CLOEXEC set (by daemon::Daemon::new), so pcid inherited
a closed fd and panicked in PipeWriter::from_raw_fd.
Fix: create a new pipe in hwd before spawning pcid. Pass the write end
as INIT_NOTIFY with CLOEXEC cleared (via pre_exec). Drop the read end
immediately — pcid's daemon.ready() will get EPIPE, which is silently
ignored by the daemon library. This gives pcid a valid fd while still
being fully non-blocking from hwd's perspective.
Root cause: hwd used daemon::Daemon::spawn(pcid) which blocks waiting
for pcid's readiness signal. But pcid only signals readiness after
completing full PCI enumeration. On real Intel hardware with complex
ACPI tables, enumeration can hang (unresponsive device, AML deadlock),
causing pcid to never signal readiness, hwd to never signal its own
readiness, and init to stall the entire initfs phase.
Fix: replace blocking daemon::Daemon::spawn with std::process::Command::spawn
(fire-and-forget). hwd signals its own readiness immediately, allowing
init to continue the initfs phase regardless of pcid's enumeration progress.
pcid runs independently and registers the pci scheme when ready.
Also: promote pcid enumeration completion log from debug to info level.
Suppress EPIPE in SchemeDaemon::ready_with_fd() to eliminate broken pipe
errors from gpiod, i2cd, ucsid at boot. Handle ENODEV gracefully in audiod
when /scheme/audiohw is absent. Both fixes verified: QEMU boots to login
prompt with zero non-fatal errors, patch applies cleanly on clean rebuild.
- IOAPIC: enable full IOAPIC initialization on AMD/Intel bare metal,
dual GSI 0/2 timer mapping for platform compatibility, NMI handler
uses raw COM1 PIO writes to avoid mutex deadlock
- HPET: counter validation, graceful fallback to PIT when HPET missing
- PS/2: fix 0xFE RESEND handling in all MouseState variants, add
controller flush/self-test retry/aux port test from Linux 7.0
- ACPI: defer AML evaluation to avoid blocking initfs driver spawn
- VT chain: remove duplicate rootfs service files (inputd, vesad,
fbcond, getty) that were already handled by initfs phase 1 and the
legacy 30_console script from minimal.toml
- QEMU verified: boots to login prompt, 20 rootfs units (was 26),
single login prompt (was double), only 1 expected error (wifictl)
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
Regenerate aggregate base patch to include ihdgd device ID additions
for modern Intel integrated GPUs (12th-14th Gen, Core Ultra, Arrow Lake).
This allows pcid-spawner to match and load ihdgd on current Intel laptops.

Rebuild base/acpid patch as comprehensive unified diff combining: DMAR iterator fix, FADT shutdown via PM1a/PM1b CNT_BLK with S5 sleep types from _S5 AML, ACPI reset register reboot with keyboard controller fallback (port 0x64, 0xFE), and power methods (_PS0/_PS3/_PPC). GenericAddress now supports memory-mapped and I/O port writes. Reboot wired into main.rs event loop with reboot_requested flag. All ivrs/mcfg stub references removed. Validated with git apply --check against upstream base source.

The base patch referenced ivrs and mcfg modules that don't exist in the source tree, causing build failures. Removed the module declarations, imports, and init calls. MCFG is already handled by pcid (the PCI daemon). IVRS (AMD IOMMU) needs real implementation, not a stub. DMAR iterator fix and Dmar::init() call preserved.

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
