drm/amd/display: Reject non-zero src_y and src_x for video planes

2021-07-19T08:04:49+00:00

commit c6c6a712199ab355ce333fa5764a59506bb107c1 upstream. [Why] This hasn't been well tested and leads to complete system hangs on DCN1 based systems, possibly others. The system hang can be reproduced by gesturing the video on the YouTube Android app on ChromeOS into full screen. [How] Reject atomic commits with non-zero drm_plane_state.src_x or src_y values. v2: - Add code comment describing the reason we're rejecting non-zero src_x and src_y - Drop gerrit Change-Id - Add stable CC - Based on amd-staging-drm-next v3: removed trailing whitespace Signed-off-by: Harry Wentland Cc: stable@vger.kernel.org Cc: nicholas.kazlauskas@amd.com Cc: amd-gfx@lists.freedesktop.org Cc: alexander.deucher@amd.com Cc: Roman.Li@amd.com Cc: hersenxs.wu@amd.com Cc: danny.wang@amd.com Reviewed-by: Nicholas Kazlauskas Acked-by: Christian König Reviewed-by: Hersen Wu Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

[How] For negative widths, use zero such that validation will prune the configuration correctly and disallow MPO.
