drm/amd/display: Refactor HWSS into component folder

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

[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] Driver doesn't need T7 delay for OLED panels, since it doesn't control power sequence. [How] This delay can be skipped to optimize resume times.

drm/amd/display: Don't check registers, if using AUX BL control

2023-09-11T21:14:36+00:00

[Why] Currently the driver looks DCN registers to access if BL is on or not. This check is not valid if we are using AUX based brightness control. This causes driver to not send out "backlight off" command during power off sequence as it already thinks it is off. [How] Only check DCN registers if we aren't using AUX based brightness control.

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.
