drm/amd/display: Update FIXED_VS Retimer HWSS Test Pattern Sequences

2024-02-14T22:13:03+00:00

[WHY] Need to fix some broken logic and sequencing in initial commit [HOW] Fix logic handling override deprogramming when exiting SQ128. Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case. Move LTTPR 128b/132b check out of requires_hwss and check during runtime, as LTTPR caps are not populated on initial call. Add pending_test_pattern to link state to allow HWSS to set FFE overrides on retimer TX and/or skip setting APU TX FFE depending on requested pattern. Use updated clock source for SQ128 override sequence. Skip HW FFE preset programming when performing test pattern overrides.

drm/amd/display: Add DP audio BW validation

2024-01-15T23:35:39+00:00

[Why] Timings with small HBlank (such as CVT RBv2) can result in insufficient HBlank bandwidth for audio SDP transmission when DSC is active. This will cause some higher bandwidth audio modes to fail. The combination of CVT RBv2 timings + DSC can commonly be encountered in MST scenarios. [How] Add DP audio bandwidth validation for 8b/10b MST and 128b/132b SST/MST cases and filter out modes that cannot be supported with the current timing config.

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

2023-12-19T19:59:02+00:00

[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.
