drm/amdgpu: apply the RV2 system aperture fix to RN/CZN as well

2024-02-05T20:14:30+00:00

[ Upstream commit 16783d8ef08448815e149e40c82fc1e1fc41ddbf ] These chips needs the same fix. This was previously not seen on then since the AGP aperture expanded the system aperture, but this showed up again when AGP was disabled.

Re-revert "drm/amd/display: Enable Replay for static screen use cases"

2024-02-05T20:14:30+00:00

[ Upstream commit d6398866a6b47e92319ef6efdb0126a4fbb7796a ] 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.

drm/amd/display: Align the returned error code with legacy DP

commit bfe79f5fff1300d96203383582b078c7b0aec80a upstream. [Why] For usb4 connector, AUX transaction is handled by dmub utilizing a differnt code path comparing to legacy DP connector. If the usb4 DP connector is disconnected, AUX access will report EBUSY and cause igt@kms_dp_aux_dev fail. [How] Align the error code with the one reported by legacy DP as EIO.

drm/amd/display: fix bandwidth validation failure on DCN 2.1

2024-02-01T00:19:08+00:00

commit 3a0fa3bc245ef92838a8296e0055569b8dff94c4 upstream. 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.

drm/dp_mst: Fix fractional DSC bpp handling

2024-01-25T23:35:31+00:00

[ Upstream commit 7707dd6022593f3edd8e182e7935870cf326f874 ] The current code does '(bpp << 4) / 16' in the MST PBN calculation, but that is just the same as 'bpp' so the DSC codepath achieves absolutely nothing. Fix it up so that the fractional part of the bpp value is actually used instead of truncated away. 64*1006 has enough zero lsbs that we can just shift that down in the dividend and thus still manage to stick to a 32bit divisor. And while touching this, let's just make the whole thing more straightforward by making the passed in bpp value .4 binary fixed point always, instead of having to pass in different things based on whether DSC is enabled or not. v2: - Fix DSC kunit test cases.

drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR

2024-01-10T16:17:01+00:00

commit 202260f64519e591b5cd99626e441b6559f571a3 upstream. 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.
