drm/amd/display: Include scaling factor for SubVP command

2022-08-16T22:14:20Z

[Description] For SubVP scaling cases, we must include the scaling info as part of the cmd. This is required when converting OTG line to HUBP line for the MALL_START_LINE programming.

drm/amd/display: Unblank hubp based on plane visibility

2021-01-14T04:43:14Z

[WHY] DCN10 uses plane visibility to determine when to unblank HUBP; there is no reason DCN20+ should not do the same. [HOW] In addition to changing the check in HWSEQ, we must change is_pipe_tree_visible so that it checks ODM pipe topologies as well as MPC. Since we're now checking both ODM and MPC topologies, the helper function names have been changed to reference "parent" and "child" instead of "top" and "bottom".

DRM already supports tracing DPCD transactions, there's no reason for the existence of this function. Also, it prints one byte per-line which is way too loud. So, just remove it. Reviewed-by: Nicholas Kazlauskas Signed-off-by: Lyude Paul Signed-off-by: Alex Deucher
