2024-07-01drm/amd/display: Add ASIC cap to limit DCC surface widthGeorge Shen3-0/+11
[Why] Certain configurations of DCN401 require ODM4:1 to support DCC for 10K surfaces. DCC should be conservatively disabled in those cases. The issue is that current logic limits 10K surface DCC for all configurations of DCN401. [How] Add DC ASIC cap to indicate max surface width that can support DCC. Disable DCC if this ASIC cap is non-zero and surface width exceeds it.

2024-07-01drm/amd/display: Choose HUBP unbounded request based on DML outputSung Joon Kim1-10/+2
[why] Previously, we decide on the unbounded request purely based on pipe_cnt which is a wrong variable to use to determine how many pipes are in "use". DML already accounts for number of pipes in use along with other various factors and is a more reliable method of determination.

2024-06-27drm/amd: Don't initialize ISP hardware without FWMario Limonciello1-2/+2
Although designs may contain an ISP IP block, the camera might be a USB camera. Because of this the ISP firmware is considered optional from amdgpu. However if the firmware doesn't get loaded the hardware should not be initialized. Adjust the return code for early init to ensure the IP block doesn't go through the other init and fini sequences. Also decrease the message about firmware load failure to debug so it's not as alarming to users.

[WHY] Hotplug is not detected in headless (no eDP) mode on dcn35x. With no display dcn35x goes to IPS2 powersaving state where HPD interrupt is not handled. [HOW] Use idle worker thread for periodic detection of HPD in headless mode.

2024-06-27drm/amd/display: Fix 1DLUT setting for NL SDR blendingRelja Vojvodic1-2/+2
[WHY] Enabling NL SDR blending caused the 1D LUTs to be set/populated in two different functions. This caused flickering as the LUT was set differently by the two functions, one of which should only have been modifying the 1D LUT if 3D LUT was enabled. [HOW] Added check to only modify the 1D LUT in populate_mcm if 3D LUT was enabled. Added blend_tf function update for non-main planes if the 3D LUT path was taken.
