drm/amd/display: Wrong colorimetry workaround

2024-03-15T14:48:21+00:00

[ Upstream commit b1a98cf89a695d36c414653634ea7ba91b6e701f ] [Why] For FreeSync HDR, native color space flag in AMD VSIF(BT.709) should be used when intepreting content and color space flag in VSC or AVI infoFrame should be ignored. However, it turned out some userspace application still use color flag in VSC or AVI infoFrame which is incorrect. [How] Transfer function is used when building the VSC and AVI infoFrame. Set colorimetry to BT.709 when all the following match: 1. Pixel format is YCbCr; 2. In FreeSync 2 HDR, color is COLOR_SPACE_2020_YCBCR; 3. Transfer function is TRANSFER_FUNC_GAMMA_22; Tested-by: Mark Broadworth Reviewed-by: Krunoslav Kovac Acked-by: Rodrigo Siqueira Signed-off-by: Ma Hanghong Signed-off-by: Alex Deucher Stable-dep-of: e6a7df96facd ("drm/amd/display: Fix MST Null Ptr for RV") Signed-off-by: Sasha Levin

drm/amd/display: Disable PSR-SU on Parade 0803 TCON again

2024-02-01T00:17:08+00:00

commit 571c2fa26aa654946447c282a09d40a56c7ff128 upstream. When screen brightness is rapidly changed and PSR-SU is enabled the display hangs on panels with this TCON even on the latest DCN 3.1.4 microcode (0x8002a81 at this time). This was disabled previously as commit 072030b17830 ("drm/amd: Disable PSR-SU on Parade 0803 TCON") but reverted as commit 1e66a17ce546 ("Revert "drm/amd: Disable PSR-SU on Parade 0803 TCON"") in favor of testing for a new enough microcode (commit cd2e31a9ab93 ("drm/amd/display: Set minimum requirement for using PSR-SU on Phoenix")). As hangs are still happening specifically with this TCON, disable PSR-SU again for it until it can be root caused.

drm/amd/display: prevent potential division by zero errors

2023-09-19T10:28:06+00:00

commit 07e388aab042774f284a2ad75a70a194517cdad4 upstream. There are two places in apply_below_the_range() where it's possible for a divide by zero error to occur. So, to fix this make sure the divisor is non-zero before attempting the computation in both cases.

commit 072030b1783056b5de8b0fac5303a5e9dbc6cfde upstream. A number of users have reported that there are random hangs occurring caused by PSR-SU specifically on panels that contain the parade 0803 TCON. Users have been able to work around the issue by disabling PSR entirely. To avoid these hangs, disable PSR-SU when this TCON is found.

drm/amd/display: fix PSR-SU/DSC interoperability support

2023-05-11T14:03:03+00:00

[ Upstream commit 13b90cf900ab69dd5cab3cc5035bc7614037e64e ] Currently, there are issues with enabling PSR-SU + DSC. This stems from the fact that DSC imposes a slice height on transmitted video data and we are not conforming to that slice height in PSR-SU regions. So, pass slice_height into su_y_granularity to feed the DSC slice height into PSR-SU code.
