drm/amd/display: Create optc.h file

2023-11-07T17:03:30+00:00

For all the components that participate in DCN architecture, there is a header in the dc/inch/hw. For some reason, OPTC broke this pattern and added all the primary functions/structs associated with that in the dcn10_optc.h file. For consistency's sake, this commit introduces a new optc.h file and extracts the code from dcn10_optc to this new file.

drm/amd/display: Refactor DPG test pattern logic for ODM cases

2023-10-09T21:00:57+00:00

[Why] Current DPG test pattern logic does not account for ODM configuration changes after test pattern has already been programmed. For example, if ODM2:1 is enabled after test pattern is already being output, the second pipe is not programmed to output test pattern, causing half the screen to be black. [How] Move DPG test pattern parameter calculations into separate function. Whenever ODM pipe configuration changes, re-calculate DPG test pattern parameters and program DPG if test pattern is currently enabled.
