4465dd0e41 drm/amd/display: Refactor SubVP cursor limiting logic
[WHY]
There are several gaps that can result in SubVP being enabled with
incompatible HW cursor sizes, and unjust restrictions to cursor size due
to wrong predictions on future usage of SubVP.

[HOW]
- remove "prediction" logic in favor of tagging based on previous SubVP
  usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
  due to an attempt to enable SubVP

b6fcc3867d drm/amd/display: Add support to configure CRC window on specific CRC instance
[Why]
Have the need to specify the CRC window on specific CRC engine.
dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always
resets CRC engine at first.

[How]
Add index parameter to dc_stream_configure_crc() for selecting the desired crc
engine. Additionally, add another parameter to specify whether to skip the
default reset of crc engine.

1c86c81a86 drm/amd/display: fix page fault due to max surface definition mismatch
DC driver is using two different values to define the maximum number of
surfaces: MAX_SURFACES and MAX_SURFACE_NUM. Consolidate MAX_SURFACES as
the unique definition for surface updates across DC.

It fixes page fault faced by Cosmic users on AMD display versions that
support two overlay planes, since the introduction of cursor overlay
mode.

e69d43356f drm/amd/display: Move fpo_in_use to stream_status
[Description]
Refactor code and move fpo_in_use into stream_status to avoid
unexpected changes to previous dc_state (i.e., current_state).
Since stream pointers are shared between current and new dc_states,
updating parameters of one stream will update the other as well
which causes unexpected behaviors (i.e., checking that fpo_in_use
isn't set in previous state and set in the new state is invalid).
To avoid incorrect updates to current_state, move the fpo_in_use flag
into dc_stream_status since stream_status is owned by dc and are not
shared between different dc_states.

66eba12a54 drm/amd/display: Do cursor programming with rest of pipe
Cursors are always programmed independently of updates on other
planes. When atomic commits program cursor and surface updates
together the cursor update might be locked out by the surface
update and not take effect.

To combat this program cursor and surface updates together via
dc_update_planes_and_stream to ensure they can be applied
atomically.

When cursor updates come on their own use the old method
to program the cursor as dc_update_planes_and_stream isn't
handling this case correctly (yet), leading to a flickering
screen.

f63f86b5af drm/amd/display: Separate setting and programming of cursor
We're seeing issues when user-space tries to do an atomic update of
the primary surface, as well as the cursor. These two updates are
separate calls into DC and don't currently act as an atomic update.
This might lead to cursor updates being locked out and cursors
stuttering.

In order to solve this problem we want to separate the setting
and programming of cursor attributes and position. That's what
we're doing in this patch. The subsequent patch will then be
able to use the cursor setters in independent cursor updates,
as well as in atomic commits.

6e4337f695 drm/amd/display: Unify optimize_required flags and VRR adjustments
[why]
There is only a single call to dc_post_update_surfaces_to_stream so
there is no need to have two flags to control it. Unifying this to a
single flag allows dc_stream_adjust_vmin_vmax to skip actual
programming when there is no change required.

[how]
Remove wm_optimze_required flag and set only optimize_required in its
place. Then in dc_stream_adjust_vmin_vmax, check that the stream timing
range matches the requested one and skip programming if they are equal.

4c4583fd39 drm/amd/display: Hook up 'content type' property for HDMI
Implements the 'content type' property for HDMI connectors.
Verified by checking the avi infoframe on a connected TV.

This also simplifies a lot of the code in that area as well, there were
a lot of temp variables doing very little and unnecessary logic
that was quite confusing.

It is not necessary to check for support in the EDID before sending a
'content type' value in the avi infoframe also.

v2:
- rebase to amd-staging-drm-next

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)

- refactor amdgpu_dm_crtc_handle_crc_window_irq()
- disable PSR before activating secure_display on a crtc
- check if secure_display is activated before enabling psr

[WHY]
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.

Set ODM flag in stream and commit stream when change
in ODM has been detected due to policy change.
