acpid: load SystemQuirkFlags from in-memory DMI at init via
redox-driver-sys::quirks::toml_loader::load_dmi_system_quirks.
Store as a field on AcpiContext and expose via system_quirks().
Wire two consumers:
- FORCE_S2IDLE in set_global_s_state(3): routes S3 entry to
s2idle preparation instead. LG Gram 16Z90TP, Framework 16,
late Dell XPS advertise \_S3 in DSDT but the firmware refuses
the SLP_TYP write and hangs / silently no-ops.
- NO_LEGACY_PM1B in set_global_s_state(*): skips the PM1b write
even when FADT reports a non-zero pm1b_control_block. LG
firmware reports a PM1b block that does not exist on the
platform; writes wedge the controller.
ps2d: load SystemQuirkFlags from /scheme/acpi/dmi at init via
redox_driver_sys::quirks::system_quirks(). Wire one consumer:
- KBD_DEACTIVATE_FIXUP in Ps2::init(): skips SetDefaultsDisable
(0xF5) during keyboard init. LG Gram + some Dell/HP/Lenovo
keyboards wedge or drop keys when 0xF5 is sent (Linux
atkbd.c keyboard_broken[] / atkbd_deactivate_input tables).
acpid/src/dmi.rs: reframe misleading 'stub' docstring on
try_load_existing() — the function is a real round-trip reader
for /scheme/acpi/dmi, not a stub.
Cargo.lock regenerated to include the new redox-driver-sys path
dependency in acpid and ps2d.
This is the consumer-wiring deliverable for LG Gram Round 1
(local/docs/evidence/lg-gram/ASSESSMENT-2026-07-26.md). The
matching redox-driver-sys stub-replacement work
(load_dmi_acpi_quirks real loader, PANEL_ORIENTATION_TABLE
populated with Linux DRM entries, ACPI_FLAG_NAMES + TOML parser)
lands in the parent repo in the same Round 1 push.
acpi_irq1_skip_override remains documented as needing kernel IRQ
setup work (out of scope for Round 1).
