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.

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.

2024-01-03Re-revert "drm/amd/display: Enable Replay for static screen use cases"Ivan Lipski2-30/+1
This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5. Since, it causes a regression in which eDP displays with PSR support, but no Replay support (Sink support <= 0x03), fail to enable PSR and consequently all IGT amd_psr tests fail. So, revert this until a more suitable fix can be found. This got brought back accidently with the backmerge.

2024-01-03drm/amd/display: Fixing stream allocation regressionRelja Vojvodic1-1/+1
For certain dual display configs that had one display using a 1080p mode, the DPM level used to drive the configs regressed from DPM 0 to DPM 3. This was caused by a missing check that should have only limited the pipe segments on non-phantom pipes. This caused issues with detile buffer allocation, which dissallow subvp from being used Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Reviewed-by: Dillon Varone <dillon.varone@amd.com> Reviewed-by: Martin Leung <martin.leung@amd.com> Acked-by: Rodrigo Siqueira <rodrigo.siqueira@amd.com> Signed-off-by: Relja Vojvodic <relja.vojvodic@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2024-01-03drm/amd/display: Verify disallow bits were cleared for idleNicholas Kazlauskas1-2/+10
[Why] A hang was observed where a read-modify-write access occurred due to the register for idle state being shared between DMCUB and driver. dmcub read - idle allow / no commit driver read - idle allow / no commit driver write - idle disallow / no commit dmcub write - idle allow / commit Resulting in DMCUB re-entering IPS after a disable and keeping the allow high. [How] Long term we need to split commit/allow into two registers or use shared DRAM state, but short term we can reduce the repro rate by ensuring that the disallow went through by bounding the expected worst case scenario.

So, need to do display mode validation for streams on dpia links to avoid oversubscription of dp tunnel bandwidth.
