drm/amd/display: Fix dmub soft hang for PSR 1
[Why]
Unexpected change of aux hw mapping causes dmub soft hang when
initiate aux transation at wrong aux channel.
ddc_channel stands for hw dp aux index which is from vbios,
but link_index is pure software concept for link count depending on which link
is probed first. They are not interchangeable.
dmub aux transaction could pass if happens eDP link_index gets
the same value as vbios ddc_channel, e.g., ddc_channel = 1, link_index = 1
if they gets different, e.g., ddc_channel = 2, link_index = 0, overwrite
ddc_channel with link_index will have wrong ddc channel being used for aux
transaction in dmub PSR, cause aux transaction soft hang.
[How]
ddc_channel mapping to each link is determined by vbios and further
parsed in dc. Such info. should not be touched in any kind, otherwise
the mapping is screwed up leading to aux transaction timeout.

drm/amd/display: Maintain consistent mode of operation during encoder assignment
[Why]
While applying a state to hardware, there is a transition period where
the back-end is reset using the old state; then enabled using the new
state.
Generally, the link encoder configuration module queries
stream-to-encoder assignments in either the new or old state based on a
mode variable. During the transition there is a need to query both
states, however toggling this mode variable can lead to incorrect
programming of encoders.
[How]
- Add new function to explicity query stream-to-encoder assignment
in the current state rather than intermittently switch the mode
of operation of the link encoder assignment module.
- Add additional checks for encoder assignment defects.
- Explicitly reset the mode of operation if application of state
to hardware ends prematurely.

Add a safe transistion state that minimizes pipe usage before programming

drm/amd/display: Apply ODM 2:1 policy for single display configuration
[Why]
Most of the time, a single display uses the ODM combine. When using
multi-display, we use ODM combine only if it is necessary. These cases
are not flexible enough for us, and we can improve them to take
advantage of our hardware. We want to have more control over the ODM
policy.
[How]
This commit add a new debug flag named
enable_single_display_2to1_odm_policy to control the ODM policy and
another flag named enable_dp_dig_pixel_rate_div_policy to fine control
the ODM combine. This is possible by adding a new "pipe.dest" parameter
that can be set to ODM 2:1 combined if we use a single display. For
dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for
ODM combine. Note that this feature affects the following registers:
- timing.pix_clk_100khz -> DP_VID_M, DP_VID_N
- requested_pix_clk_100hz -> DP_DTOn_PHASE
- OTGn_PIXEL_RATE_DIVK2
- DP_PIXEL_PER_CYCLE_PROCESSING_MODE
- DIG_FIFO_OUTPUT_PIXEL_MODE
- DP_VID_N_MUL

drm/sched: Partial revert of 'drm/sched: Keep s_fence->parent pointer'
Problem:
This patch caused negative refcount as described in [1] because
for that case parent fence did not signal by the time of drm_sched_stop and hence
kept in pending list the assumption was they will not signal and
so fence was put to account for the s_fence->parent refcount but for
amdgpu which has embedded HW fence (always same parent fence)
drm_sched_fence_release_scheduled was always called and would
still drop the count for parent fence once more. For jobs that
never signaled this imbalance was masked by refcount bug in
amdgpu_fence_driver_clear_job_fences that would not drop
refcount on the fences that were removed from fence drive
fences array (against prevois insertion into the array in
get in amdgpu_fence_emit).
Fix:
Revert this patch and by setting s_job->s_fence->parent to NULL
as before prevent the extra refcount drop in amdgpu when
drm_sched_fence_release_scheduled is called on job release.
Also - align behaviour in drm_sched_resubmit_jobs_ext with that of
drm_sched_main when submitting jobs - take a refcount for the
new parent fence pointer and drop refcount for original kref_init
for new HW fence creation (or fake new HW fence in amdgpu - see next patch).

Revert "drm/amd/display: ignore modifiers when checking for format support"
This reverts commit
5089c4a8ebea3c3ad9eedf038dad7098ebc06131.
This breaks validation and enumeration of display capable modifiers.
The early return true means the rest of the validation code never gets
executed, and we need that to enumerate the right modifiers to userspace
for the format.
The modifiers that are in the initial list generated for a plane are the
superset for all formats and we need the proper checks in this function
to filter some of them out for formats with which they're invalid to be
used.
Furthermore, the safety contract here is that we validate the incoming
modifiers to ensure the kernel can handle them and the display hardware
can handle them. This includes e.g. rejecting multi-plane images with DCC.
Note that the legacy swizzle mechanism allows encoding more swizzles, and
at fb creation time we convert them to modifiers and reject those with
no corresponding modifiers. If we are seeing rejections I'm happy to
help define modifiers that correspond to those, or if absolutely needed
implement a fallback path to allow for less strict validation of the
legacy path.
However, I'd like to revert this patch, since any of these is going to
be a significant rework of the patch, and I'd rather not the regression
gets into a release or forgotten in the meantime.
