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.
Per ground-truth: BOOT-PROCESS-ASSESSMENT.md, IOMMU-SPEC-REFERENCE.md, and LINUX-BORROWING-RUST-IMPLEMENTATION-PLAN.md are gone. Replaced with "(deleted)" markers. Lines 73-74 (duplicate BOOT-PROCESS-ASSESSMENT.md refs) collapsed to a single marker.
- CHANGELOG.md: added comprehensive 2026-06-30 entry covering
the full ACPI fork-sync (Phases A-D) and the redbear-sessiond
consumer port. Lists the 7 critical gaps that are now fully closed
and the 2 still open (DMAR + _WAK infrastructure).
- local/docs/ACPI-FORK-SYNC-STRATEGY-2026-06-30.md: added Phase D
outcome section with the Linux 7.1 cross-reference findings
(acpi_enter_sleep_state pattern), the changes applied to acpid
and redbear-sessiond, and the final gap-closure table.
- local/docs/ACPI-IMPROVEMENT-PLAN.md: updated "Current Truthful
Status" to reflect that acpid now follows the Linux 7.1 sleep
pattern with _PTS/_SST evaluation, thermal/power enumeration
works, AML mutex is real, parse_lnk_irc validates ranges, and
S5 works end-to-end. S1-S4 paths still need _WAK + wakeup
vector + P-state preservation (Gap #4b scaffolded but not
implemented). DMAR init still disabled (Gap #2 needs real-HW
investigation).
- local/docs/boot-logs/README.md: added
REDBEAR-MINI-BOOT-PS2D-INPUTD-LOG-FIX.md to the inventory.
Also:
- Removed scratch file local/docs/ACPI-FIX-PLAN-2026-06-30.md
(superseded by the longer ACPI-FORK-SYNC-STRATEGY-2026-06-30.md).
- udev-shim: replace .expect() with graceful errors (no more panic on Broken pipe)
- P4-initfs: remove duplicate sessiond (conflicted with config)
- accessibility/ime/keymapd: break instead of exit(1) on EBADF
- P6 driver patches rebased
- Docs: archive old reports, add implementation master plan
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
