drm/amd/display: Implement BIOS parser external encoder control

2026-02-23T19:28:32Z

The VBIOS has a function called ExternalEncoderControl which controls the DP bridge encoders that some GPUs use for analog and LVDS output. Fixup this old functionality. For reference, see the legacy non-DC amdgpu display code: amdgpu_atombios_encoder_setup_external_encoder() - Set same parameters for the ENABLE action as the SETUP action - Add missing enum values for DDC setup and DAC load detection - Fix the bits per color field - Clarify the code that sets the link rate - Expose the function so that it can be called by rest of DC A subsequent commit will call this function from DCE HWSS.

Pass the correct enum values as expected by the VBIOS. Previously the actual bit depth integer value was passed, which was a mistake. Fixes: 7fb4f254c8eb ("drm/amd/display: Add SelectCRTC_Source to BIOS parser") Reviewed-by: Alex Deucher Signed-off-by: Timur Kristóf Signed-off-by: Alex Deucher

drm/amd/display: shrink struct members

2025-12-08T19:25:12Z

On a 32-bit ARM system, the audio_decoder struct ends up being too large for dp_retrain_link_dp_test. link_dp_cts.c:157:1: error: the frame size of 1328 bytes is larger than 1280 bytes [-Werror=frame-larger-than=] This is mitigated by shrinking the members of the struct and avoids having to deal with dynamic allocation. feed_back_divider is assigned but otherwise unused. Remove both. pixel_repetition looks like it should be a bool since it's only ever assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t. Remove ss_percentage_divider. Unused. Shrink refresh_rate as it gets assigned to at most a 3 digit integer value. Signed-off-by: Rosen Penev Reviewed-by: Alex Hung Signed-off-by: Alex Deucher
