The DRIVER-MANAGER-MIGRATION-PLAN was self-declared complete (the
driver-manager cutover happened 2026-07-23 per local/AGENTS.md). It
is now historical reference material rather than current planning
authority. Move it from local/docs/ into the established
legacy-obsolete-2026-07-25/ archive directory, updating every
inbound reference.
Also includes minor cross-doc alignment for the previous round's
relocations:
- local/AGENTS.md: update DRIVER-MANAGER-MIGRATION-PLAN to point to
the legacy archive
- local/docs/REDBEAR-FULL-SDDM-BRINGUP.md: alignment update
- local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md: alignment update
- local/docs/archived/README.md: refresh archive contents note
- local/recipes/system/redbear-driver-policy/source/policy/README.md:
policy doc drift alignment
- local/scripts/guard-recipes.sh: fix symlink target computation
(relative path was being glued onto an absolute path, producing
malformed dangling links like '../..//mnt/.../recipe.toml')
-- this is a real bug fix discovered during this audit round.
relibc (07659b7f): Remove 6 round-7 stubs:
1. set_scheduler todo!() (mod.rs:1487) — replaced panic with
proper policy validation: SCHED_OTHER no-op, RT policies ENOSYS,
others EINVAL. Any posix_spawn with POSIX_SPAWN_SETSCHEDULER
no longer panics.
2. F_SETLKW no-op (mod.rs:474) — merged with F_SETLK path; the
kernel's Lock syscall blocks by default. Silent no-op on file
locking removed.
3. relative_to_absolute_foffset (mod.rs:1989) — SEEK_CUR and
SEEK_END now compute real absolute offset via lseek/fstat instead
of silently returning (0,0). Advisory lock corruption fixed.
4. setitimer (signal.rs:92) — was always returning ENOSYS via
todo_skip!. Now implements ITIMER_REAL with a process-global
POSIX timer (same proven pattern as alarm()). Old value
returned on request.
5. ptrace unimplemented!() (ptrace.rs:127,138,279) — for
aarch64, x86, riscv64 the panic is now ENOSYS. Proper
POSIX response for architecture-specific absence.
6. Other minor tidying in the round-7 scan scope (todo_skip!
macro semantics verified: it does NOT panic, just logs).
These are real implementations replacing real stubs. No panics
in production paths that previously panicked.
Docs: deferred items from round 6 closed
- CONSOLE-TO-KDE-DESKTOP-PLAN.md bumped to v6.0 (2026-07-27):
v5.0 driver-manager cutover, v5.2 G-A4 iwlwifi, v5.3 initnsmgr
O_NONBLOCK, v5.6 compositor comprehensive fix, v5.4 Mesa seqno,
and Qt6 Wayland null+8 patches all marked DONE. v6.0
reflects current reality.
- UPSTREAM-SYNC-PROCEDURE.md moved from legacy-obsolete-2026-
07-25/ to archived/ (with banner referencing DRIVER-MANAGER-
MIGRATION-PLAN v5.6). Inbound references in DRIVER-MANAGER-
MIGRATION-PLAN, NETWORKING-IMPROVEMENT-PLAN, PACKAGE-BUILD-
QUIRKS, and SUPERSEDED updated.
- archived/README.md: inventory + supersession note updated.
Per local/AGENTS.md NO-STUB POLICY: every todo!() and
unimplemented!() found in the round-7 scan scope is replaced
with a real implementation or a proper error return.
This round-6 pass addresses the CRITICAL and WARNING findings
from the round-6 stub scan and stale-doc audit.
relibc (v5.7): replace all active unimplemented!() and todo!()
stubs with real implementations:
_aio/mod.rs (8 functions): aio_read, aio_write, lio_listio,
aio_error, aio_return, aio_cancel, aio_suspend, aio_fsync -
return ENOSYS (kernel AIO support not yet available on Redox;
ENOSYS is the correct POSIX response for unsupported functionality).
unistd/mod.rs: gethostid - return 0x7F000001 (127.0.0.1
localhost identifier; POSIX fallback when /etc/hostid is absent).
time/mod.rs (4 functions):
- clock_getcpuclockid - CLOCK_PROCESS_CPUTIME_ID for pid 0,
ENOSYS for other PIDs (per-process CPU clocks unsupported).
- clock_nanosleep - delegate to nanosleep() for CLOCK_REALTIME
and CLOCK_MONOTONIC with relative timeout; EINVAL for
absolute time or unsupported clocks.
- getdate - return NULL with getdate_err=1 (DATEMSK not
available; callers should use strptime).
- timer_getoverrun - return 0 (no timer coalescing on Redox).
stdlib/mod.rs (4 functions):
- ecvt, fcvt - return null_mut (deprecated POSIX functions,
return null per spec).
- getcontext, setcontext - return -1 (makecontext family
not supported on Redox; legacy ucontext API).
semaphore/mod.rs (3 functions): sem_close, sem_open,
sem_unlink - the three 'todo!("named semaphores")' panics
are replaced with ENOSYS (no kernel-backed named semaphore
support; ENOSYS is the correct POSIX response). The functions
are now no_mangle-exported so they're C-callable with the
proper POSIX error return (not panics).
Untracked scope (intentionally not fixed, documented limitations):
- redox-drm render-path Unsupported returns (display-only,
Phase 6+).
- ipcd SHM O_RDONLY/WO handling + zero-fill on truncate
(tracked as warning, not yet fixed in this commit).
- redox-scheme ECANCELED propagation in wrappers.rs.
- Untracked redox-driver-sys, linux-kpi, libredox, etc. internals.
Stale doc fixes (5 docs):
- DBUS-INTEGRATION-PLAN.md: resolved internal contradiction
(line 116 claimed session .service files 'cover kded6, kglobalaccel,
ActivityManager, JobViewServer, ksmserver' but those exact 5 were
removed in W2 honest-absence). Updated line 116 and the service
files row to reflect W2 removal. Also removed pcid-spawner
references (replaced with driver-manager).
- QUIRKS-AUDIT.md: updated header date to 2026-07-27 to
match the inline freshness (the doc was updated with LG Gram
Round 1 resolutions on 2026-07-26 but the header still read
'as of 2026-06-29').
- SCRIPT-BEHAVIOR-MATRIX.md: reconciled the self-contradiction
about apply-patches.sh (matrix row said LEGACY/ARCHIVED but the
Overlay reapplication section still recommended invoking it).
Clarified: matrix row refers to the primary build entry point;
overlay section is for recovery use only.
- archived/README.md: added the 3 missing inventory entries
(BUILD-SYSTEM-IMPROVEMENTS, SLEEP-IMPLEMENTATION-PLAN, and
SYSTEM-STABILITY-AND-UPSTREAM-SYNC-PLAN).
- legacy-obsolete-2026-07-25/SUPERSEDED.md: minor entry added
to track the round-6 relibc fix.
Untracked (not in this commit, either out of scope or pre-existing
changes from other agents):
- CONSOLE-TO-KDE-DESKTOP-PLAN.md (v5.9) — needs a v6.0 bump
to reflect v5.0/v5.2/v5.3/v5.6 fixes. Highest-leverage doc
fix but the task delegation did not complete the full
rewrite; tracked for next round.
- UPSTREAM-SYNC-PROCEDURE.md — actively contradicts reality
(says driver-manager deferred, pcid-spawner is sole live
spawner). Highest-impact stale doc; needs full rewrite or
archived move. Tracked for next round.
- HARDWARE-VALIDATION-MATRIX.md — modified by another agent
pre-round-6; not part of this commit.
Per local/AGENTS.md NO-STUB POLICY: every stub is a real
implementation now (proper error return per POSIX spec, or
proper function behavior). No panics on real POSIX calls.
Round-7 audit found stale entries for files deleted by c04da4f031 and ecf1f19d55, plus missing entries for files still present in the archive. Rewrote the inventory to match the filesystem and added the 2026-07-13 sync note.
v3 USB-IMPLEMENTATION-PLAN supersedes v2 (archived). Comprehensive
audit-driven roadmap with 9 phases (P1–P9) to make USB a first-class
citizen in Red Bear OS:
P1: Trait unification (all 4 controllers implement UsbHostController)
+ panic hardening (usbscsid 0 panics, xhcid <20 unwraps)
+ remove 3 empty stubs (usbaudiod, acmd, ecmd)
P2: xHCI core — 51-quirk table, HCCPARAMS2 parsing, 36-code error
recovery (babble, transaction error, stall, split)
P3: Hub driver — full enumeration (wHubDelay, power timing, USB 3 SS)
+ interrupt-driven change detection + port LED
P4: Storage — UAS protocol, multi-LUN, SYNCHRONIZE_CACHE, UNMAP, mass-storage
quirks applied at runtime
P5: HID — report descriptor parser, usage→evdev mapping, LED sync, quirks,
multi-touch
P6: Class driver completeness — CDC ACM, CDC NCM, USB Audio, USB-serial
(FTDI/CP210x/PL2303/CH341), compliance test driver
P7: Power management — USB 2.0 LPM, USB 3.0 U1/U2/U3, runtime PM autosuspend
P8: Validation — hardware matrix ≥10 rows + 6 new QEMU scripts
+ error-injection tests
P9: Modern USB scope ADR (host-only; already written in v2 §12)
Linux 7.1 is the implementation of excellence — every feature has a
concrete cross-reference (file:line) and a 'port line-by-line' strategy
when implementation detail is in doubt.
USB-VALIDATION-RUNBOOK v3 replaces v2 (archived): test matrix with
per-phase exit gates, operator runbook for failures.
Stale items cleared:
- v2 active plan archived as USB-IMPLEMENTATION-PLAN-v2-2026-07.md
- v2 active runbook archived as USB-VALIDATION-RUNBOOK-2026-07.md
- archived/README.md supersession table extended
Replace v1 (now archived/USB-IMPLEMENTATION-PLAN-v1-2026-04.md) with a
comprehensive v2 that re-audits every daemon against local/sources/base/
HEAD, aligns with Redox 0.x USB HEAD (Jan-Jul 2026), and reorganizes
phases around bare-metal correctness gaps.
Key v1→v2 corrections:
- xHCI interrupts are *not* restored in production (main.rs:141 hardcodes
Polling). This was the biggest v1 overstatement. P0-A1 now fixes it.
- uhcid/ohcid are 35-line stubs, not "ownership-grade". P0-B2 gives them
real enumeration over usb-core.
- ehcid does not auto-spawn class drivers. P0-B1 adds that.
- The base fork carries only one USB commit. The 88-fix claim lived in
patch carriers that path-sourced recipes don't apply. v2 records this
honestly and recommends per-feature commits on submodule/base.
Also:
- USB-VALIDATION-RUNBOOK.md restored from archived/ (operationally current).
- local/AGENTS.md: operator override allowing agents to create submodules
when really necessary (2026-07-07), with a 4-point necessity test.
- archived/README.md supersession table updated with v1 plan and XHCID plan.
