Sync the base fork with 13 upstream commits (xhci event-processing
dedup + IRQ race fix, randd permission simplification, nvmed TimeSpec
fix, /dev/ptmx, fpath legacy-path cleanup, dynamically-linked init
fix, and more). Brings process_one_event into the tree, satisfying the
verify-fork-functions gate for base.
Conflicts resolved (3 of 8 overlapping files; 5 auto-merged):
- drivers/usb/xhcid/src/xhci/irq_reactor.rs: took upstream's
process_one_event/EventProcessResult refactor (b2ed85ea) including
the a01d3ce6 race fix (process events between NoEvent and
unmasking), and re-applied the Red Bear SPURIOUS_REBOOT quirk on the
NoEvent warning (downgrade to debug when quirked).
- randd/src/main.rs: took upstream's permission-handling
simplification (e26db606); re-applied the RB fcntl improvement
(F_GETFL/F_GETFD/F_SETFL/F_SETFD handling, Linux random_fops xref)
and the is_cpu_feature_detected early-return cleanup. Dropped
test_scheme_perms (deleted by upstream's simplification).
- Makefile: kept upstream's new /dev symlink block (dev/null, ptmx,
random, urandom, zero, tty, stdin/stdout/stderr).
Verified: cargo check clean; 57/57 tests pass (xhcid 35, usbhubd 14,
xhci trb 8); verify-fork-functions.sh --no-fetch base reports all
upstream functions present.
The keyboard input path pushed the raw character bytes, so the Enter key
(a bare CR on the keymap) never produced an LF. Line-oriented readers on
the console (e.g. a shell's read_line) then never saw a completed line and
appeared to hang. Convert CR->LF here, matching the serial input path
(push_input_bytes).
fbcond now mirrors all framebuffer-console output to the kernel debug (serial)
scheme AND feeds serial input back into the active VT's input queue. Previously,
once fbcond took over the console after display handoff the serial line went
silent (headless operators saw the boot stop at 'Performing handoff' and never
saw the getty login prompt, which draws only to the framebuffer VT). Now the
same console — boot log, login prompt, and shell — is fully usable over serial,
reusing the working framebuffer getty for both surfaces.
For fbbootlog, fbcon and the disk drivers there is no load bearing use
of the fpath output. And for chan relibc already handles both the legacy
and new format.
Re-adds the archived-but-unapplied scrollback support: a 1000-line ring
buffer in TextScreen capturing all output (incl. pre-handoff boot log), a
Handle::Scrollback variant opened via /scheme/fbcon/<vt>/scrollback, and a
read path returning the retained buffer. Adapted to the current single-step
openat scheme protocol.
Per local/docs/PATCH-PRESERVATION-AUDIT-2026-07-12.md the base
fork was carrying only 38 of 100 patches in local/patches/base/.
The other 62 patches' content was silently missing from the fork
working tree, even though their .patch files were preserved.
This commit re-applies 41 patches that genuinely still apply
cleanly + 17 hunks that partially applied. Recovery covers:
- D-Bus initfs service wiring (P4-initfs-dbus-services)
- USB service wiring (P4-initfs-usb-drm-services)
- netcfg/dhcp/dhcpv6 driver fixes
- acpid shutdown/PM/quirk fixes
- inputd/ps2d hard-fail logging
- pcid driver interface refinements (server cmd channel)
- virtio-core for VirtualBox support
- ixgbed/rtl8139/rtl8168 net drivers
- ahcid NCQ + per-function interrupt coalescing
- logd persistent logging
- bootstrap procmgr race-condition fixes
- cargo version pin to +rb0.3.0 (synchronized release branch)
58 files changed, +1444/-318 lines.
Untracked mnt/ tree and *.orig / *.rej files cleaned up after
patch application (leftover from absolute-path patch headers).
