62cc621604 drm/amd/display: Check Vactive for VRR active for FPO + Vactive
[Description]
- For FPO + Vactive cases, we rely on the Vactive display to be at
  it's nominal refresh rate because the Vactive pipe may not necessarily
  assert P-State allow while it's in VBLANK
- For cases where the Vactive display has a stretched VBLANK due to
  VRR, we could underflow when trying to complete an FPO + Vactive
  MCLK switch because the FPO display has limited VBLANK time in
  waiting for the Vactive display to assert P-State allow naturally
- Block FPO + Vactive if the Vactive display has VRR active (variable
  or fixed)

[Description]
- When entering into a SubVP config that requires a minimal
  transition we need to retain phantom pipes and also restore
  the mall config
- This is because the min transition will remove phantom pipes
  from the context (shallow copy) and not restore it's original

Reprogramming the stream despite no changes in ODM combine mode.
Reprogramming the stream would cause intermittent black screen on
display which could only be recovered through enable/disable sequence.

[HOW]
Fixed bug where we detected a change in ODM combine mode despite ODM
combine mode being disabled. Also removed code which required stream to
be reprogrammed once a change in ODM combine mode was noticed. Lastly we
do not support dynamic ODM switching for HDMI TMDS and FRL on DCN32,
therefore we never want to change its ODM policy.

With ODM policy 2 to 1, there exists a new use case
scenario where stream content is unchanged, but ODM
may be used.  When this happens, the stream needs
to be committed with a new pipe setting.
This did not happen due to stream change
detection logic not accounting for ODM.

in ODM has been detected due to policy change.

97ca308925 drm/amd/display: Add minimal pipe split transition state
[WHY?]
When adding/removing a plane to some configurations, unsupported pipe
programming can occur when moving to a new plane.  Such cases include pipe
split on multi-display, with MPO, and/or ODM.

[HOW?]
Add a safe transistion state that minimizes pipe usage before programming
new configuration. When adding a plane, the current state has the least
pipes required so it is applied without splitting.  This must be applied
prior to updating the plane_state for seamless transition.  When removing a
plane, the new state has the least pieps required so it is applied without
splitting.

This reverts commit 3c4d55c9b9becedd8d31a7c96783a364533713ab.

Revert the commit because:
- It's incomplete of the function dm_set_dpms_off() for mst case.  For
  stream sinks whithin the same mst topology, they share the same dc_link.
  dm_set_dpms_off() tries to update one mst stream only which is
  incomplete.
- Setting dpms off should be triggered by usermode. Besdies, it seems
  usermode does release relevant resource for mst & non-mst case when
  unplug connecotr now.

policy. Furthermore, an optimized value for min_dst_y_next_start is
calculated and written to its register. When exiting freesync, another
full update is triggered and default values are restored.

prevents full updates when VRR changes until a mode change.

719349f849 drm/amd/display: Remove unused flag from stream state
[why & how]
Removing unused DSC flag which is incorrect and is not used.
We are only using stream->timing.flags.DSC for DSC's current
state. Stream state as an input parameter and should not contain
any past status flags.

f42ef862fb drm/amd/display: Add dynamic link encoder selection.
[Why]
Some display endpoints may be programmably mapped to compatible link
encoders. The assignment of link encoders to links has to be dynamic to
accommodate the increased flexibility in comparison to conventional
display endpoints.

[How]
- Add link encoder assignment tracking variables.
- Execute link encoder assignment algorithm before enabling link and
release link encoders from links once they are disabled.

fa2a3786c4 drm/amd/display: reuse current context instead of recreating one
[Why]
Currently we discard the current context and recreate it. The current
context is what is applied to the HW so we should be re-using this
rather than creating a new context.

Recreating the context can lead to mismatch between new context and the
current context

For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.

[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.
