drm/amd/display: Exit idle optimizations before HDCP execution

2024-06-27T11:52:15+00:00

[ Upstream commit f30a3bea92bdab398531129d187629fb1d28f598 ] [WHY] PSP can access DCN registers during command submission and we need to ensure that DCN is not in PG before doing so. [HOW] Add a callback to DM to lock and notify DC for idle optimization exit. It can't be DC directly because of a potential race condition with the link protection thread and the rest of DM operation.

drm/amd/display: Wrong colorimetry workaround

2022-10-27T18:45:14+00:00

[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
