2017-10-21drm/amd/display: Fix memoryleak during S3 resume.Leo (Sunpeng) Li1-4/+0
Do not create dc_state within display_resume, since it's being constructed within atomic check. Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2017-10-21drm/amd/display: add hardware_planes_only to list of affected planesShirish S1-6/+24
For SoC's having software designed cursor plane, should be treated differently than hardware cursor planes. The DRM core initializes cursor plane by default with legacy_cursor_update set. Hence legacy_cursor_update can be use effectively to handle software cursor planes' update and atomicity functionalities. This patch uses this variable to decide in the atomic_check to whether add a requested plane to the list of affected planes or not, hence fixing the issue of co-existence of MPO, i.e, setting of available hardware planes like underlay and updation of cursor planes as well. Without this patch when underlay is set from user space, only blank screen with backlight is visible.
