drm/amd/display: Remove unnecessary Freesync w/a from DCN32

2026-04-17T19:20:45Z

[Why/How] A workaround was previously used for certain Freesync cases that would override the vstartup_start value from DML to position the SDP correctly. This is no longer needed in DCN32 and above, so remove the workaround.

drm/amd/display: Fixed Silence complier warnings in dc

2026-03-30T19:12:15Z

[Why] Resolve compiler warnings by marking unused parameters explicitly. [How] In .c and .h function definitions, keep parameter names in signatures and add a line with `(void)param;` in function body Preserved function signatures and avoids breaking code paths that may reference the parameter under conditional compilation.

drm/amd/display: replace fast_validate with enum dc_validate_mode

2025-06-03T19:36:23Z

[Why] The boolean fast_validate is used as an input parameter in multiple functions. To support more scenarios, we are replacing it with enum dc_validate_mode. [How] The enum dc_validate_mode introduces three possible values: 1) DC_VALIDATE_MODE_AND_PROGRAMMING: Apply the mode to hardware 2) DC_VALIDATE_MODE_ONLY: Check whether the mode can be supported 3) DC_VALIDATE_MODE_AND_STATE_INDEX: Check if the mode can be supported, and determine the optimal voltage level needed to support it.

drm/amd/display: Refactor SubVP cursor limiting logic

2025-05-05T16:58:49Z

[WHY] There are several gaps that can result in SubVP being enabled with incompatible HW cursor sizes, and unjust restrictions to cursor size due to wrong predictions on future usage of SubVP. [HOW] - remove "prediction" logic in favor of tagging based on previous SubVP usage - block SubVP if current HW cursor settings are incompatible - provide interface for DM to determine if HW cursor should be disabled due to an attempt to enable SubVP Reviewed-by: Alvin Lee Signed-off-by: Dillon Varone Signed-off-by: Ray Wu Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
