drm/amd/display: Fix seamless boot sequence[WHY]When the system powers up eDP with external monitors in seamless bootsequence, stutter get enabled before TTU and HUBP registers beingprogrammed, which resulting in underflow.[HOW]Enable TTU in hubp_init.Change the sequence that do not perpare_bandwidth and optimize_bandwidthwhile having seamless boot streams.Cc: Mario Limonciello <[email protected]>Cc: Alex Deucher <[email protected]>Cc: [email protected]Reviewed-by: Nicholas Kazlauskas <[email protected]>Signed-off-by: Lo-an Chen <[email protected]>Signed-off-by: Paul Hsieh <[email protected]>Signed-off-by: Alex Hung <[email protected]>Tested-by: Daniel Wheeler <[email protected]>Signed-off-by: Alex Deucher <[email protected]>

drm/amd/display: Add hubp cache reset when powergating[Why]When HUBP is power gated, the SW state can get out of sync with thehardware state causing cursor to not be programmed correctly.[How]Similar to DPP, add a HUBP reset function which is called whereverHUBP is initialized or powergated. This function will clear the cursorposition and attribute cache allowing for proper programming when theHUBP is brought back up.Cc: Mario Limonciello <[email protected]>Cc: Alex Deucher <[email protected]>Cc: [email protected]Reviewed-by: Sung Lee <[email protected]>Signed-off-by: Aric Cyr <[email protected]>Signed-off-by: Wayne Lin <[email protected]>Tested-by: Daniel Wheeler <[email protected]>Signed-off-by: Alex Deucher <[email protected]>
