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: Set the DML2 attribute to false in all DCNs older than version 3.5

2023-10-26T22:41:22+00:00

When DML2 was introduced, it targeted only new DCN versions. For controlling which ASIC should use this new version of DML, it was introduced the using_dml2 attribute. To avoid ambiguities, this commit explicitly sets using_dml2 to false in all ASICs that do not support DML2.

drm/amd/display: Refactor HWSS into component folder

[why] Rename hw_sequencer to hwseq. Move all hwseq files to unique folder hwss. [how] creating hwss repo in dc, and moved the dcnxx_hwseq.c and .h files into corresponding new folders inside the hwss and cleared the linkage errors by adding relative paths in the Makefile.template.

drm/amd/display: switch DC over to the new DRM logging macros

2023-09-26T21:00:21+00:00

For multi-GPU systems it is difficult to tell which GPU a particular message is being printed for and that is undesirable because it complicates debugging efforts. Also, the new macros allow us to enable logging for particular parts of the codebase more selectively (since we no longer need to throw everything at DRM_DEBUG_KMS()). So, for the reasons outlined above we should switch to the new macros. We can accomplish this by using the existing DC_LOGGER code to pass around the relevant `struct drm_device` which will be fed to the new macros in logger_types.h. Also, we must get rid of all instances of the DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use the DC logger there and we can simply refer to the macros directly there instead.

[Why&How] For enabling automated testing, add a hook to DCHUBBUB interface so that mall status can be queried by userspace through debugfs. This removes dependence on requiring a userspace tool like UMR for querying status for MALL static screen IGT test.

drm/amd/display: implement pipe type definition and adding accessors

2023-08-15T22:08:28+00:00

[why] There is a lack of encapsulation of pipe connection representation in pipe context. This has caused many challenging bugs and coding errors with repeated logic to identify the same pipe type. [how] Formally define pipe types and provide getters to identify a pipe type and find a pipe based on specific requirements. Update existing logic in non dcn specific files and dcn32 and future versions to use the new accessors.
