drm/amd/display: Remove last parts of timing_trace

2024-11-04T16:26:36Z

Commit c2c2ce1e9623 ("drm/amd/display: Optimize passive update planes.") removed the last caller of context_timing_trace. Remove it. With that gone, no one is now looking at the 'timing_trace' flag, remove it and all the places that set it. Signed-off-by: Dr. David Alan Gilbert Signed-off-by: Alex Deucher

drm/amd/display: Add logs to record register read/write

2024-10-01T21:37:07Z

[Why] There are some issues which customer only can provide full dump for analyze, without register history, it's hard to debug HW status. [How] 1. Put register read/write into WPP log so we can trace the logs from full memory dump. 2. MALL doesn't add into WPP, add it.

drm/amd/display: Avoid overflow assignment in link_dp_cts

2024-07-27T21:34:20Z

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it can overflow. As a result, sampling_rate is changed to uint32_t. Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should only be assigned to a value less or equal than 4. This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

Merge v6.10-rc6 into drm-next

2024-07-05T08:47:28Z

The exynos-next pull is based on a newer -rc than drm-next. hence backmerge first to make sure the unrelated conflicts we accumulated don't end up randomly in the exynos merge pull, but are separated out. Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma code, and cherry-pick conflict in xe. Signed-off-by: Daniel Vetter

drm/amd/display: fix graphics_object_id size

2024-05-29T18:48:31Z

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.
