drm/amd/display: get dprefclk ss info from integration info table

2023-12-19T19:59:02Z

[why & how] we have two SSC_En: we get ssc_info from dce_info for MPLL_SSC_EN. we used to call VBIOS cmdtbl's smu_info's SS persentage for DPRECLK SS info, is used for DP AUDIO and VBIOS' smu_info table was from systemIntegrationInfoTable. since dcn35 VBIOS removed smu_info, driver need to use integrationInfotable directly.

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

2023-09-26T21:00:21Z

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.
