Phase R13 (2026-06-07) — Laptop/Embedded DMI quirks. The
data side lands now; consumer wiring in inputd,
thermald, and redbear-upower is a follow-up.
Changes:
1. PlatformDmiQuirkFlags (mod.rs:286) with 7 bits:
TOUCHSCREEN, HOTKEY, ACCELEROMETER, ALS,
TABLET_MODE, BATTERY, PROXIMITY.
2. PlatformSubsystem enum (mod.rs:316) — dispatch label
for TOML and consumers. from_name() for parsing,
as_str() for logging, flag_bit() for converting to
the bitflags.
3. PlatformDmiQuirkRule (dmi.rs:566) — DMI match +
subsystem. Each entry fires one subsystem.
4. load_platform_dmi_quirks() (dmi.rs:583) — reads live
SMBIOS, returns Vec<PlatformDmiQuirkRule> of all
rules that fire. Falls back to empty vector if DMI
data is unavailable.
5. read_toml_platform_dmi_entries + parse_platform_dmi_toml
(toml_loader.rs) — new [[platform_dmi_quirk]] TOML
table with sub-table + string.
Unknown subsystem names log a warning and skip.
6. 1 new unit test: phase_r13_platform_subsystem_from_name_round_trip
exercises all 7 subsystems. 124/124 tests pass.
7. quirks.d/80-platform-x86.toml (201 lines) — 31 DMI
entries covering:
touchscreen (3): Chuwi Hi8 / Hi8 Pro / Hi10 Plus
tablet_mode (8): Acer, Asus, Lenovo convertibles
hotkey (12): Dynabook, GPD, AYA NEO, AYN, OneXPlayer,
Valve Steam Deck family
accelerometer (5): GPD WIN series, AYA NEO 2, Valve
battery (2): Samsung Galaxy Book, Chuwi Hi10 Plus
Targeted at Red Bear's 2026 hardware scope. The full
Linux 7.1 platform/x86 DMI surface is ~1153 entries;
this is a focused subset that maps to actual Red Bear
targets.
cargo test: 124/124 (was 123, +1 for the new test).
cargo check: clean.
Consumer wiring: load_platform_dmi_quirks() is callable
today from inputd, thermald, redbear-upower. Each
consumer can filter on rule.subsystem to dispatch the
appropriate behavior. This is a follow-up commit.
