* drm/amd/display: switch DC over to the new DRM logging macrosHamza Mahfooz2023-09-261-119/+25
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | In some instances, the GPU is transmitting repeated frame to the sink without any updates or changes in the content. These repeat transmission are wasteful, resulting in power draw in different aspects of the system 1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic prevents power down of parts of this HW path. 2. GPU is transmitting pixel data to the display through the main link of the DisplayPort interface. This prevents power down of both the Source transmitter (TX) and the Sink receiver (RX)  The concepts of utilizing replay is similar to PSR, but there is a benefit of: Source and Sink remaining synchronized which allows for - lower latency when switching from replay to live frames - enable the possibility of more use cases - easy control of the sink's refresh rate during replay Due to Source and Sink remaining timing synchronized, Replay can be activated in more UI scenarios.
