2024-09-18drm/amd/display: Clean up dsc blocks in accelerated modeMartin Tsai1-0/+50
[WHY] DSC on eDP could be enabled during VBIOS post. The enabled DSC may not be disabled when enter to OS, once the system was in second screen only mode before entering to S4. In this case, OS will not send setTimings to reset eDP path again. The enabled DSC HW will make a new stream without DSC cannot output normally if it reused this pipe with enabled DSC. [HOW] In accelerated mode, to clean up DSC blocks if eDP is on link but not active when we are not in fast boot and seamless boot.

[WHY] There are some monitor timings that seem to be supported without DSC but actually require DSC to be displayed. A VESA SCR introduced a new max uncompressed pixel rate cap register that we can use to handle these edge cases. [HOW] SST: Read caps from link and invalidate timings that exceed the max limit but do not support DSC. Then check for options override when determining BPP. MST: Read caps from virtual DPCD peer device or daisy chained SST monitor and set validation set BPPs to max if pixel rate exceeds uncompressed limit. Validation set optimization continues as normal.
