Round 1 of the LG Gram 16Z90TP compatibility work. Two parallel
workstreams in one commit:
1. Stub replacements in redox-driver-sys (per project zero-tolerance
policy):
- load_dmi_acpi_quirks() (was hardcoded AcpiQuirkFlags::empty()):
real loader walking a new compiled-in DMI_ACPI_QUIRK_RULES table
(currently empty — documented why) plus a new [[dmi_acpi_quirk]]
TOML section parser in toml_loader.rs. The full 16-flag
ACPI_FLAG_NAMES mapping is added so TOML entries can use any
AcpiQuirkFlags variant by name.
- PANEL_ORIENTATION_TABLE (was empty placeholder): populated with
10 real entries ported from Linux 7.x
drivers/gpu/drm/drm_panel_orientation.c — GPD Pocket/Pocket 2/
WIN Max 2, ASUS T100HA/T101HA/TP200SA, Lenovo IdeaPad D330,
Chuwi Hi8 Pro/Hi10 Plus, Teclast X98 Plus II. Each entry cites
its Linux source commit.
- PLATFORM_RULES (kept empty): documented why intentionally empty
(Linux platform-wide DMI quirks are pre-2020 platform workarounds
not needed by Red Bear's modern targets).
2. Broken reference fixes after the 2026-07-25 archive
(commit 589a1044e6 moved 9 docs to legacy-obsolete-2026-07-25/
but didn't update references). 30+ files referenced the moved
docs by their old local/docs/<name>.md path. This commit updates
every reference to point at local/docs/legacy-obsolete-2026-07-25/
<name>.md so links work again. Files touched: AGENTS.md,
README.md, docs/{AGENTS,README,07-RED-BEAR-OS-IMPLEMENTATION-PLAN}.md,
local/AGENTS.md, 14 docs under local/docs/, local/patches/README.md,
5 scripts under local/scripts/.
The matching acpid+ps2d consumer wiring landed earlier today in
submodule/base commit 45452c5a (force_s2idle, no_legacy_pm1b,
kbd_deactivate_fixup). The bootstrap reference fix is submodule/base
commit 263a41a9. Both are tracked by the updated submodule pointer
in this commit.
Build verification: redox-driver-sys 80 cargo tests pass. acpid/ps2d
host tests not runnable (require cross-compile). Canonical build
attempts uncovered two pre-existing failures unrelated to Round 1:
relibc edition-2024 unsafe-block issue in crtn, and the base fork's
'common' path resolution relies on the build script's overlay
integrity auto-repair which is currently failing. Neither is in code
touched by Round 1.
See local/docs/evidence/lg-gram/ASSESSMENT-2026-07-26.md for the full
round-by-round assessment and next-round plan.

|
|
| D1 P1 `/etc/driver-manager.d/` policy loader | ✅ | 🔲 | `local/recipes/system/driver-manager/source/src/policy.rs`; reads TOML blacklist; consulted at probe |

|
|
| D2 PM hooks (Driver::suspend/resume + signal_then_collect) | ✅ | 🔲 | Real SIGTERM/SIGKILL in `DriverConfig`; needs iommu/pcid SetPowerState wiring for actual D3 |

|
|
| D4 SIGHUP reload worker | ✅ | N/A | `driver-manager/src/sighup.rs`; worker polls `AtomicBool` and calls `SharedBlacklist::replace()`; 1 unit test; `libc::signal` install is left to the host program |
|
|
| D4 blackbox test scripts | ✅ | N/A | 8 scripts in `local/scripts/test-driver-manager-*.sh` |
|
|
| D4 heartbeat publisher | ✅ | N/A | `driver-manager/src/heartbeat.rs`; writes JSON to `/var/run/driver-manager.heartbeat.json` every 5s; 3 unit tests |
|
|
| D4 AER listener infrastructure | ✅ | N/A | `driver-manager/src/aer.rs`; polls `/scheme/acpi/aer`; 7 unit tests; falls back to log-and-no-op when scheme is absent |
|
|

### Status note (2026-07-20)
|
|
|
|
- The login-based QEMU proofs (PS/2 + serio, monotonic timer, IOMMU first-use, USB storage BOT)
|
|
now run through `local/scripts/qemu-login-expect.py` (stdlib python) instead of the host
|
|
`expect` tool — no external dependency, per-step timeouts, and safe retry on premature QEMU
|
|
death. See `local/docs/legacy-obsolete-2026-07-25/IRQ-AND-LOWLEVEL-CONTROLLERS-ENHANCEMENT-PLAN.md` § "Runtime proof
|
|
status (2026-07-20)".
|
|
- MSI-X (virtio-net) and xHCI interrupt-driven mode were re-confirmed on the current
|
|
`redbear-mini` ISO — once more on 2026-07-20 ~09:10 JST via `test-lowlevel-controllers-qemu.sh`
|
|
(log-grep legs, unaffected by host contention).
|
|
- Re-confirmation of the login-based legs (PS/2, timer, BOT) with the new
|
|
harness is pending an uncontended host — the current build host runs a parallel QEMU-testing
|
|
workload (a concurrent agent session under `~/.claude/jobs/` with its own QMP-controlled
|
|
guest) that SIGKILLs competing QEMU processes; boots reach getty but the
|
|
login prompt is not observed within the timeout there. The ✅ marks above reflect prior
|
|
validation of those legs. A retry loop (`/tmp/opencode/a2-retry.sh`) is armed to run the
|
|
PS/2, timer, and USB-storage legs automatically once the foreign QEMU workload exits.
|
|
- The IOMMU first-use leg currently skips on `redbear-mini` runs because
|
|
`build/x86_64/redbear-full/harddrive.img` is absent — a `redbear-full` build is required
|
|
to re-confirm that leg.
|
|
- Display boots (`-vga std`) can freeze at the fbcond `Performing handoff` step (the
|
|
`reopen_for_handoff()` path can block rather than return `EAGAIN` for retry). Headless
|
|
(`-vga none`) boots avoid it. Tracked separately on the graphics stack.
