Add complete HCI protocol module (hci.rs) with packet types, 55+ constants,
command builders (Reset, Read BD Addr, Read Local Version, LE scan/connect),
event parsers, and structured result types. Add USB transport abstraction
(usb_transport.rs) with UsbHciTransport trait and StubTransport for testing.
Wire btusb daemon with endpoint descriptor parsing, HCI init sequence
(Reset → Read BD Addr → Read Local Version), ControllerState state machine,
and enhanced status output. Replace all expect()/unwrap() calls in btctl
and wifictl with proper error handling and graceful fallback.
91 btusb tests, 27 btctl tests, 2 wifictl tests passing.
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)
fetch.rs: use full commit hash for deterministic checkout. recipe.rs:
refactor recipe handling for cleaner patch application. sync-upstream:
add dry-run mode and improve rebase error recovery.
215 fixes across 33 Rust source files replacing unwrap/expect/panic
with graceful error handling in init, all boot-critical daemons,
and the six graphics driver packages. Fixes inverted scheduler
conditions_met() logic that prevented rootfs from mounting.
Both P2 patches were stale — generated against an older upstream HEAD whose
context lines shifted after redox.patch modified the same files. Regenerated
from scratch against the current upstream commit so they apply cleanly.
