That means it's impossible that svm_range_bo_release is running concurrently. However, there is no good way to annotate this. To avoid the problem, take a BO reference in svm_range_schedule_evict_svm_bo instead of in the worker. That way it's impossible for a BO to get freed while eviction work is pending and the cancel_work_sync call in svm_range_bo_release can be eliminated. v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also removed redundant checks that are already done in amdkfd_fence_enable_signaling.

IGT `amdgpu/amd_color/crtc-lut-accuracy` fails right at the beginning of the test execution, during atomic check, because DC rejects the bandwidth state for a fb sizing 64x64. The test was previously working with the deprecated dc_commit_state(). Now using dc_validate_with_context() approach, the atomic check needs to perform a full state validation. Therefore, set fast_validation to false in the dc_validate_global_state call for atomic check.

2024-01-05drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays ↵Joshua Ashton2-8/+13
without PSR The check for sending the vsc infopacket to the display was gated behind PSR (Panel Self Refresh) being enabled. The vsc infopacket also contains the colorimetry (specifically the container color gamut) information for the stream on modern DP. PSR is typically only supported on mobile phone eDP displays, thus this was not getting sent for typical desktop monitors or TV screens. This functionality is needed for proper HDR10 functionality on DP as it wants BT2020 RGB/YCbCr for the container color space.
