Revert "drm/amd/display: Add fallback configuration when set DRR"

2024-04-26T21:22:38Z

This reverts commit d76c0a23b557c6ebb3fac32548100d76a1e0ce23. This change must be reverted since it caused soft hangs when changing the refresh rate to 122 & 144Hz when using a 7000 series GPU.

drm/amd/display: Support long vblank feature

2024-03-20T17:37:37Z

[WHY] We want to support low hz case, but the original vtotal/vtotal_min/vtotal_max can't support more than 0x7FFF. [HOW] We use the 2 HW reg to contorl long vblank case. 1. OTG_V_COUNT_STOP_CONTROL -> vcount_stop 2. OTG_V_COUNT_STOP_CONTROL2 -> vcount_stop_timer vcount_stop define from which line we stop using vcount and start using vcount2. vcount_stop_timer define how long we use vcount2. Ex: Vtotal = 7 OTG_V_COUNT_STOP_CONTROL = 4 OTG_V_COUNT_STOP_CONTROL2 = 5 time : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 vcount : 0, 1, 2, 3, - - - - - 4, 5, 6 vcount2 : 0, 1, 2, 3, 4, Reviewed-by: Jun Lei Acked-by: Alex Hung Signed-off-by: ChunTao Tso Signed-off-by: Robin Chen Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Implement wait_for_odm_update_pending_complete

2024-03-20T17:12:58Z

[WHY] Odm update is doubled buffered. We need to wait for ODM update to be completed before optimizing bandwidth or programming new udpates. [HOW] implement wait_for_odm_update_pending_complete function to wait for: 1. odm configuration update is no longer pending in timing generator. 2. no pending dpg pattern update for each active OPP.
