drm/amd/display: Ensure vmin and vmax adjust for DCE

2023-07-05T17:29:23+00:00

commit 2820433be2a33beb44b13b367e155cf221f29610 upstream.

[Why & How]
In the commit 32953485c558 ("drm/amd/display: Do not update DRR while
BW optimizations pending"), a modification was added to avoid adjusting
DRR if optimized bandwidth is set. This change was only intended for
DCN, but one part of the patch changed the code path for DCE devices and
caused regressions to the kms_vrr test. To address this problem, this
commit adds a modification in which dc_stream_adjust_vmin_vmax will be
fully executed in DCE devices.

drm/amd/display: Do not update DRR while BW optimizations pending

2023-07-05T17:29:23+00:00

commit 32953485c558cecf08f33fbfa251e80e44cef981 upstream.

[why]
While bandwidth optimizations are pending, it's possible a pstate change
will occur.  During this time, VSYNC handler should not also try to update
DRR parameters causing pstate hang

[how]
Do not adjust DRR if optimize bandwidth is set.

drm/amd/display: fix the system hang while disable PSR

2023-06-28T09:13:57+00:00

[ Upstream commit ea2062dd1f0384ae1b136d333ee4ced15bedae38 ]

[Why]
When the PSR enabled. If you try to adjust the timing parameters,
it may cause system hang. Because the timing mismatch with the
DMCUB settings.

[How]
Disable the PSR before adjusting timing parameters.

drm/amd/display: Add wrapper to call planes and stream update

2023-06-28T09:13:57+00:00

[ Upstream commit 81f743a08f3b214638aa389e252ae5e6c3592e7c ]

[Why & How]
This commit is part of a sequence of changes that replaces the commit
sequence used in the DC with a new one. As a result of this transition,
we moved some specific parts from the commit sequence and brought them
to amdgpu_dm. This commit adds a wrapper inside DM that enable our
drivers to do any necessary preparation or change before we offload the
plane/stream update to DC.

drm/amd/display: Use dc_update_planes_and_stream

2023-06-28T09:13:57+00:00

[ Upstream commit f7511289821ffccc07579406d6ab520aa11049f5 ]

[Why & How]
The old dc_commit_updates_for_stream lacks manipulation for many corner
cases where the DC feature requires special attention; as a result, it
starts to show its limitation (e.g., the SubVP feature is not supported
by it, among other cases). To modernize and unify our internal API, this
commit replaces the old dc_commit_updates_for_stream with
dc_update_planes_and_stream, which has more features.

drm/amd/display: edp do not add non-edid timings

2023-06-21T14:02:10+00:00

commit e749dd10e5f292061ad63d2b030194bf7d7d452c upstream.

[Why] most edp support only timings from edid. applying
non-edid timings, especially those timings out of edp
bandwidth, may damage edp.

[How] do not add non-edid timings for edp.

drm/amd/display: limit DPIA link rate to HBR3

commit 7c5835bcb9176df94683396f1c0e5df6bf5094b3 upstream.

[Why]
DPIA doesn't support UHBR, driver should not enable UHBR
for dp tunneling

drm/amd/display: add ODM case when looking for first split pipe

2023-06-14T09:16:55+00:00

commit 59de751e3845d699e02dc4da47322b92d83a41e2 upstream.

[Why]
When going from ODM 2:1 single display case to max displays, second
odm pipe needs to be repurposed for one of the new single displays.
However, acquire_first_split_pipe() only handles MPC case and not
ODM case

[How]
Add ODM conditions in acquire_first_split_pipe()
Add commit_minimal_transition_state() in commit_streams() to handle
odm 2:1 exit first, and then process new streams
Handle ODM condition in commit_minimal_transition_state()

drm/amd/display: Only wait for blank completion if OTG active

[ Upstream commit 82a10aff9428f1d190de55ef7971fdb84303cc7a ]

[why]
If OTG is not active, waiting for blank completion will always fail and
timeout resulting in unnecessary driver delays.

[how]
Check that OTG is enabled before waiting for blank.
