drm/amd/display: Add missing encoder setup to DACnEncoderControl

2026-01-05T22:33:28Z

Apparently the DAC encoder needs to be set up before use. The BIOS parser in DC did not support this so I assumed it was not necessary, but the DAC doesn't work without it on some GPUs.

drm/amd/display: Add DAC_LoadDetection to BIOS parser (v2)

2025-10-28T14:09:55Z

DAC_LoadDetection can be used to determine whether something is connected to an analog connector by determining if there is an analog load. This causes visible flickering on displays, so we only resort to using this when the connected display doesn't have an EDID. For reference, see the legacy display code: amdgpu_atombios_encoder_dac_load_detect v2: Only clear corresponding bit from BIOS_SCRATCH_0.

drm/amd/display: Add SelectCRTC_Source to BIOS parser

2025-10-28T14:08:24Z

The SelectCRTC_Source command will be used to change which CRTC should be connected to which encoder. For reference, see the legacy display code: amdgpu_atombios_encoder_set_crtc_source Signed-off-by: Timur Kristóf Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

drm/amd/display: Connect dig_fe to otg directly instead of calling bios

2019-01-25T21:15:37Z

[Why] After call bios table crtc_source_select, dal will program fmt again. The bios table program dig_source_select and other fmt register for bios usage which is redundancy and uncessary.
