base: bump submodule — acpid GPE _Lxx/_Exx dispatch + PM timer (0485ae66)
Also: redox-drm DPCD AUX stub replaced with real implementation.
- redox-drm/intel/display.rs: read_dpcd skeleton (hardcoded
vec![0x12,0x0A,0x84,0x01]) replaced with real native AUX channel
read. aux_read() implements the DP AUX protocol: native read cmd
(0x9) + 20-bit address + len-1 written to DP_AUX_CH_DATA, SEND_BUSY
+ message size + MTL POWER_REQUEST to DP_AUX_CH_CTL, DONE/error
polling, ACK reply check, payload extract. Per zero-stub policy.
Reference: Linux intel_dp_aux.c + intel_dp_aux_regs.h, VESA DP 1.4.
- redox-drm/intel/backlight.rs: remove leftover fake_mmio_size test
artifact.
- Plan doc: Phase 3.3 marked code-complete (GMBUS EDID real, DPCD
AUX real; modeset proof needs host). ACPICA assessment updated with
GPE _Lxx/_Exx dispatch and PM timer.
