lg-gram-16z90tp: Phase 3.5/3.6/6.1 + Wi-Fi stub elimination
Wi-Fi (Phase 6.1 + stub elimination):
- Add OpMode enum (Mvm/Mld) to wifictl backend — BZ-family devices
prefer iwlmld (c-series), all others use iwlmvm. Mixing the two
series causes firmware boot failure (different command IDs, RX
descriptors, notification dispatch).
- Add FirmwareTableEntry struct with separate mvm/mld candidate lists.
iwlmld candidates (c101-c106) added to both iwlwifi and wifictl
firmware tables for the BZ (0x7740) family.
- Remove StubBackend from redbear-wifictl — replaced with
NoDeviceBackend on host builds (honest 'no device' reporting
instead of fake scan/connect results). Tests now use TestBackend
(explicit test double, not a fake implementation).
- Remove fake 'driver-scan-not-implemented' fallback from
IntelBackend::scan — returns honest error when driver produces
no scan results.
- 20 wifictl tests pass, 8 iwlwifi tests pass.
Display (Phase 3.5/3.6):
- Phase 3.6: GuC/HuC/GSC firmware manifest entries on DisplayPlatform.
guc_firmware_key(), huc_firmware_key(), gsc_firmware_key() per-gen.
IntelDriver::new() logs the full uC manifest at startup. Load
sequences deferred to render path (not display blocker).
- Phase 3.5: eDP backlight control module (intel/backlight.rs).
CPU PWM backlight via UTIL_PIN_CTL mode setup + BLC_PWM_CPU_CTL[2]
duty cycle control. Gen9+ register offsets (0x48250/0x48254/0x48400).
Default max brightness 93750 (SKL reference). enable/disable/
set_brightness with clamping.
Docs:
- LG Gram plan: Phase 3.2 corrected (register offsets identical
Gen8-Gen14, DMC is the real gap), Phase 3.4/3.5/3.6/6.1/9.6
marked complete.
- Wi-Fi plan: StubBackend removed from status, test count updated.
- DRM plan: GuC/HuC/GSC manifest declaration noted.
- Phase 9.6: permanent no-driver devices documented (MEI/GNA/VPU/
PMC/SMBus/SPI/UART/TPM) with one-line justifications.
