drm/amd/display: Fail atomic_check early on normalize_zpos error

2023-02-16T03:46:42+00:00

[Why]

drm_atomic_normalize_zpos() can return an error code when there's
modeset lock contention. This was being ignored.

[How]

Bail out of atomic check if normalize_zpos() returns an error.

Revert "drm/amd/display: disable S/G display on DCN 3.1.5"

2023-02-09T15:29:28+00:00

This reverts commit 3cc67fe1b3aa1ac4720e002f2aa2d08c9199a584.

Some users have reported flickerng with S/G display.  We've
tried extensively to reproduce and debug the issue on a wide
variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to.  We
disabled S/G display on a number of platforms to address this
but that leads to failure to pin framebuffers errors and
blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).
We have a parameter to disable this as a debugging option as a
way for users to disable this, depending on their use case,
and for us to help debug this further.  Having this enabled
seems like the lesser of to evils.
