c66db9e9a0 drm/amd/display: only trigger BIOS related assert for older ASICs
[Why]
Some asserts are always hit on startup/Pnp when they should only be used
to indicate when something has gone wrong.

[How]
Ignore result of getting function from bios cmd table for newer asics.

6f4835f9df drm/amd/display: Fix DCN35 set min dispclk logic
[Why]

Setting min dispclk to 50Mhz outside clock lowering function causes
unnecessary calls to SMU to lower dispclk and causes dentist hangs when
there is no stream on the pipes.

[How]

Move the set minimum dispclk logic inside the lowering dispclk if
statement.

28d43d0895 drm/amd/display: Determine IPS mode by ASIC and PMFW versions
[Why]

DCN IPS interoperates with other system idle power features, such as
Zstates.

On DCN35, there is a known issue where system Z8 + DCN IPS2 causes a
hard hang. We observe this on systems where the SBIOS allows Z8.

Though there is a SBIOS fix, there's no guarantee that users will get it
any time soon, or even install it. A workaround is needed to prevent
this from rearing its head in the wild.

[How]

For DCN35, check the pmfw version to determine whether the SBIOS has the
fix. If not, set IPS1+RCG as the deepest possible state in all cases
except for s0ix and display off (DPMS). Otherwise, enable all IPS

a08d75927f drm/amd: Introduce additional IPS debug flags
[Why]

Idle power states (IPS) describe levels of power-gating within DCN. DM
and DC is responsible for ensuring that we are out of IPS before any DCN
programming happens. Any DCN programming while we're in IPS leads to
undefined behavior (mostly hangs).

Because IPS intersects with all display features, the ability to disable
IPS by default while ironing out the known issues is desired. However,
disabing it completely will cause important features such as s0ix entry
to fail.

Therefore, more granular IPS debug flags are desired.

[How]

Extend the dc debug mask bits to include the available list of IPS
debug flags.

All the flags should work as documented, with the exception of
IPS_DISABLE_DYNAMIC. It requires dm changes which will be done in
later changes.

20b5a8f9f4 drm/amd/display: fix double free issue during amdgpu module unload
Flexible endpoints use DIGs from available inflexible endpoints,
so only the encoders of inflexible links need to be freed.
Otherwise, a double free issue may occur when unloading the
amdgpu module.

4e9e50b6ae drm/amd/display: Allow UHBR Interop With eDP Supported Link Rates Table
[WHY]
eDP 2.0 is introducing support for UHBR link rates, however current eDP ILR
link optimization does not account for UHBR capabilities.
Either UHBR capabilities will be provided via the same 128b/132b rate DPCD caps
that are currently used on DP2.1, or Table 4-13 may be updated to include UHBR
rates.

[HOW]
Add extra Supported Link Rates table translations for UHBR10/13.5/20.
Update eDP link setting optimization search to be aware of 128b/132b DPCD
rate caps in order to unblock UHBR on panels with Supported Link Rates table.

Previous multi-display HPO fix moved where HPO I/O enable/disable is performed.
The codepath now taken to enable/disable HPO I/O is not used for compliance
test automation, meaning that if a compliance box being driven at a DP1 rate
requests retrain at UHBR, HPO I/O will remain off if it was previously off.

[HOW]
Explicitly update HPO I/O after allocating encoders for test request.

737222cebe drm/amd/display: fix cursor offset on rotation 180
[why & how]
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.
