2019-03-19drm/amd/display: Fix plane address updates for video surface formatsNicholas Kazlauskas1-31/+26
[Why] For new DC planes the correct plane address fields are filled based on whether the plane had a graphics or video format. However, when we perform stream and plane updates using DC we only ever fill in the graphics format fields. This causing corruption and hangs when using video surface formats like NV12 for planes. [How] Use the same logic everywhere we update dc_plane_address - always fill in the correct fields based on the surface format type. There are 3 places this is done: - Atomic check, during DC plane creation - Atomic commit, during plane prepare_fb - Atomic commit tail, during amdgpu_dm_commit_planes We use the fill_plane_tiling_attributes in all 3 locations and it already needs the address to update DCC attributes, so the surface address update logic can be moved into this helper.

2019-03-19drm/amd/display: On DCN1, Wait for vupdate on cursor updatesDavid Francis1-0/+31
[Why] Cursor updates must acquire the pipe control lock to prevent vupdate from triggering in the middle of cursor programming. On DCN1 the pipe control lock prevents pageflips from occurring. This means that a cursor update right before vupdate can delay a pending pageflip [How] If the time until the next vupdate is less than a conservative estimate of the cursor programming time, wait until the vupdate has passed before locking.
