drm/amd/display: Include scaling factor for SubVP command

2022-08-16T22:14:20+00:00

[Description]
For SubVP scaling cases, we must include the scaling
info as part of the cmd. This is required when converting
OTG line to HUBP line for the MALL_START_LINE programming.

drm/amd/display: avoid doing vm_init multiple time

2022-08-16T22:09:16+00:00

[why]
this is to ensure that driver will not reprogram hvm_prefetch_req again if
it is done.

drm/amd/display: Update clock table policy for DCN314

2022-08-16T22:08:54+00:00

[Why & How]
Depending on how the clock table is constructed from PMFW we can run
into issues where we don't think we have enough bandwidth available
due to FCLK too low - eg. when the FCLK table contains invalid entries
or a single entry.

We should always pick up the maximum clocks for each state as a final
state in this case to prevent validation from failing if the table is
malformed.

We should also contain sensible defaults in the case where values
are invalid.

Redfine the clock table structures by adding a 314 prefix to make
debugging these issues easier by avoiding symbol name clashes.

Overall this policy more closely aligns to how we did things for 315,
but because of how the voltage rail is setup we should favor keeping
DCFCLK low rather than DISPCLK or DPPCLK - so use the max for those
in every entry.

drm/amd/display: Modify header inclusion pattern

2022-08-16T22:08:42+00:00

[Why]
Recent backport from opensource broke the Nightly tool build
that tests DC and DML for bugs and regressions. This was
because the backport had a header inclusion that was not
consistent with the AMD style of including headers was allowed
to be merged back in DML code that caused tool compilation
failures.

[How]
Modify the way in which the header file in included so that it
is consistent with AMD style of including headers. This then
automatically fixes the tool compilation process and also
helps maintain the code quality and consistency.

drm/amd/display: Fix plug/unplug external monitor will hang while playback MPO video

2022-08-16T22:08:36+00:00

[Why]
Pipes for MPO primary and overlay will be power down and power up during
plug/unplug external monitor while MPO video playback.
But the pipes were the same after plug/unplug and should not need to be
power down and power up or it will make page flip interrupt disabled and
cause hang issue.

[How]
Add pipe split change condition that not only check the top pipe pointer
but also check the index of top pipe if both top pipes are available.

drm/amd/display: Add debug parameter to retain default clock table

2022-08-16T22:08:08+00:00

[Why]
Need a way to retain default clock table to aid
the investigation into why 8k@30 display not
lighting up on dcn314

[How]
Use flag to prevent execution of bw_params helper
function and function for updating bw_bounding_box
