drm/amd/display: fix graphics_object_id size

2024-08-03T06:59:51+00:00

[ Upstream commit 6d438caaeaa1a7fae7b523e7bc4cee262b9f101a ] The graphics_object_id structure is meant to fit into 32 bits, as it's passed by value in and out of functions. A recent change increased the size to 128 bits, so it's now always passed by reference, which is clearly not intended and ends up producing a compile-time warning: drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c: In function 'construct_phy': drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c:743:1: error: the frame size of 1040 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Add back the bitfields to revert to the original size, while keeping the 'enum' type change.

drm/amd/display: Add a function for checking tmds mode

2024-04-12T04:36:47+00:00

[Why] DVI is TMDS signal like HDMI but without audio. Current signal check does not correctly reflect DVI clock programming. [How] Define a new signal check for TMDS that includes DVI to HDMI TMDS programming.

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

[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.
