drm/amd/display: fix cursor offset on rotation 180

2023-02-09T03:19:20+00:00

Cursor gets clipped off in the middle of the screen with hw rotation 180. Fix a miscalculation of cursor offset when it's placed near the edges in the pipe split case. Cursor bugs with hw rotation were reported on AMD issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/2247 The issues on rotation 270 was fixed by: https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/ that partially addressed the rotation 180 too. So, this patch is the final bits for rotation 180.

drm/amd/display: trigger timing sync only if TG is running

2022-12-06T15:13:31+00:00

[Why&How] If the timing generator isnt running, it does not make sense to trigger a sync on the corresponding OTG. Check this condition before starting. Otherwise, this will cause error like: *ERROR* GSL: Timeout on reset trigger!

drm/amd/display: Use the largest vready_offset in pipe group

2022-11-29T16:03:38+00:00

[WHY] Corruption can occur in LB if vready_offset is not large enough. DML calculates vready_offset for each pipe, but we currently select the top pipe's vready_offset, which is not necessarily enough for all pipes in the group. [HOW] Wherever program_global_sync is currently called, iterate through the entire pipe group and find the highest vready_offset.

drm/amd/display: Program pipes for ODM when removing planes

2022-11-15T16:53:08+00:00

[WHY?] Software state expects pipes to be configured for ODM, but due to the transition occurring on a plane disable, the ODM enablement code is not run. [HOW?] Update ODM when removing a plane, and dynamic ODM is active. Also acquire pipe lock when removing a plane.

drm/amd/display: move remaining FPU code to dml folder

2022-10-27T19:12:08+00:00

In the process of enabling DCN support for arm64, I found that the dcn10_resource_construct_fp function in dcn10/dcn10_resource.c still needs to use FPU. This will cause compilation to fail on ARM64 platforms because -mgeneral-regs-only is enabled by default to disable the hardware FPU. So move dcn10_resource_construct_fp from dcn10 folder to dml/dcn10 folder to enable hardware FPU for that function.
