drm/amd/display: Cleanup DML DSC input bpc validation

2021-04-09T20:53:32Z

[Why & How] Pipe input DSC bpc has a type mismatch with maximum DSC input bpc - align the maximum with the pipe input type, unsigned integer. When checking the type we shoudl also check for an implicit value of 0 and align with what the spreadsheet does - default to max. Rename output_bpc to dsc_input_bpc to reflect what the field is actually used for.

drm/amd/display: support "dummy pstate"

2019-07-18T19:27:26Z

[why] Existing support in DC for pstate only accounts for a single latency. This is sufficient when the variance of latency is small, or that pstate support isn't necessary for correct ASIC functionality. Newer ASICs violate both existing assumptions. PState support is mandatory of correct ASIC functionality, but not all latencies have to be supported. Existing code supports a "full p state" which allows memory clock to change, but is hard for DCN to support (as it requires very large buffers). New code will now fall back to a "dummy p state" support when "full p state" cannot be support. This easy p state support should always be allowed. [how] Define a new latency in socBB. Add fallback logic to support it. Note DML is also updated to ensure that fallback will always work. Signed-off-by: Jun Lei Reviewed-by: Dmytro Laktyushkin Acked-by: Leo Li Signed-off-by: Alex Deucher
