drm/amd/display: Correct color depth for SelectCRTC_Source

2026-01-05T22:31:24+00:00

Pass the correct enum values as expected by the VBIOS. Previously the actual bit depth integer value was passed, which was a mistake.

drm/amd/display: shrink struct members

2025-12-08T20:30:40+00:00

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.

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

2025-10-28T14:09:55+00:00

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: Don't use stereo sync and audio on RGB signals (v2)

2025-10-28T14:08:41+00:00

Analog video signals on VGA or DVI-A (analog part of DVI-I) don't support audio, so avoid calling any audio related functions on analog signals. Stereo sync was not set up for analog signals in the legacy display code either, so there is no loss of functionality if we omit it from DC for now. Also add a dc_is_rgb_signal similar to other dc_is_*_signal. v2: Added comment to clarify what we mean by RGB in this context.

drm/amd/display: Get maximum pixel clock from VBIOS

2025-10-28T14:08:36+00:00

We will use this for validating the pixel clock when an analog monitor is connected to VGA or DVI-I connectors. For reference, see the legacy display code: amdgpu_connector_vga_mode_valid Signed-off-by: Timur Kristóf Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher

The new analog bit will be used with DVI-I connectors. DVI-I connectors can connect to both digital and analog monitors and this bit will help distinguish between those. v2: Sanitize analog bit based on connector type.
