Fix boot-to-login: override pcid-spawner to oneshot_async, add U3 input producers, Intel HDA phases A-D
- Override 00_pcid-spawner.service to oneshot_async in redbear-legacy-base.toml:
rootfs phase no longer blocks on PCI driver init; getty/login starts immediately.
Confirmed working on both QEMU and bare metal (redbear-live-mini).
- Clean up 00_base legacy script: remove dead notify ipcd/ptyd calls, keep sudo --daemon.
- Add U3 named input producers: inputd supports per-device named producers with
fan-out to both device-specific consumers and legacy VT consumers. Migrate ps2d
and usbhidd to InputProducer trait. RESERVED_DEVICE_NAMES deduplicated.
- Add Intel HDA audio driver phases A-D: ihdad error handling (37 fixes), audio
quirks, codec path enumeration, mixer/volume control.
- Add init service start/readiness logging (always visible, not debug-gated).
- Update BOOT-PROCESS-ASSESSMENT.md: Phase 6 complete, boot procedure documented,
validation matrix updated with confirmed boot status.
- Update USB-IMPLEMENTATION-PLAN.md and INPUT-SCHEME-ENHANCEMENT.md for U2/U3 status.
