Various DCE versions had trouble with 36 bpp lb depth, requiring fixes,
last time in commit 353ca0fa5630 ("drm/amd/display: Fix 10bit 4K display
on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I
found out that on DCE-11.2 it causes dithering when there shouldn't be
any, so identity pixel passthrough with identity gamma LUTs doesn't work
when it should. This breaks various important neuroscience applications,
as reported to me by scientific users of Polaris cards under Ubuntu 22.04
with Linux 5.15, and confirmed by testing it myself on DCE-11.2.
Lets only use depth 36 for DCN engines, where my testing showed that it
is both necessary for high color precision output, e.g., RGBA16 fb's,
and not harmful, as far as more than one year in real-world use showed.
DCE engines seem to work fine for high precision output at 30 bpp, so
this ("famous last words") depth 30 should hopefully fix all known problems
without introducing new ones.
Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on
top of Linux 5.19.0-rc2 + drm-next.

[Why]
With single display odm 2:1 policy, when moving windowed MPO across
the display, we experience a momentary lag when we move between the
centre of the display and the right half of the display. This is
caused by the MPO pipe being reallocated when it crosses this
boundary
[How]
Handle two cases:
1. if the head pipe has a MPO pipe already allocated in the old
context, then use that pipe if it is available in the current
context
2. if the head pipe is on the left side, check the right side to
see if it has a MPO pipe already allocated. If so, don't use
that pipe if it is selected as the idle pipe in the current
context
Add new function pointer called .acquire_idle_pipe_for_head_pipe
that will pass in the head pipe and handle case 1
Add find_idle_secondary_pipe_check_mpo() to handle case 2
if we don't hit case 1.
In dc_add_plane_to_context(), start with head pipe and check
case 1 and 2 in call acquire_free_pipe_for_head().
If we are on the right side of the display, check case 1
again by passing in right side pipe as the new head in
call acquire_free_pipe_for_head().

[Why&How]
Add a field to store the DCN IP offset for use with runtime offset
calculation
This offset is indexed using reg*_BASE_IDX for the corresponding
group of registers. For example, address of DIG_BE_CNTL instance 0 is
calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] +
regDIG0_DIG_BE_CNTL.
{dcn,nbio}_reg_offsets are used only for the ASICs for which runtime
initializaion of offsets are enabled through the modified SR* macros
that contain an additional REG_STRUCT element in the macro definition.
DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They
are applicable starting with DCN32/321 and are not used for ASICs
upstreamed before them. ASICs before DCN32/321 will not contain any
computation that involves {dcn,nbio}_reg_offsets. For them, the
address/offset computation is done during compile time.
This is evident from the BASE_INNER definition for compile time vs run
time initialization:
Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg
Run time init: #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg]
BASE_INNER macro is local to each dcnxx_resource.c and hence different
ASICs can have either runtime or compile time initialization of offsets.
The computation of offset is done for registers all at once during
driver load and hence it does not introduce any performance overhead
during normal operation.

[why]
Unbounded request logic in resource/DML has some issues where
unbounded request is being enabled incorrectly. SW today enables
unbounded request unconditionally in hardware, on the assumption
that HW can always support it in single pipe scenarios.
This worked until now because the same assumption is made in DML.
A new DML update is needed to fix a bug, where there are single
pipe scenarios where unbounded cannot be enabled, and this change
in DML needs to be ported in, and dcn32 resource logic fixed.
[how]
First, dcn32_resource should program unbounded req in HW according
to unbounded req enablement output from DML, as opposed to DML input
Second, port in DML1 update which disables unbounded req in some
scenarios to fix an issue with poor stutter performance

[why]
Ideally link capability should be independent from the link
configuration that we decide to use in enable link. Otherwise if link
capability is changed after validation has completed, we could end up
enabling a link configuration with invalid configuration. This would
lead to over link bandwidth subscription or in the extreme case
causes us to enable HPO link to a DIO stream.
[how]
Add a new struct in pipe ctx called link config. This structure will
contain link configuration to enable a link. It will be populated
during map pool resources after we validate link bandwidth. Remove
the reference of verified link cap during enable link process and
use link config in pipe ctx instead.

[Why]
In single display configuration, windowed MPO does not work
with ODM combine.
[How]
For ODM + MPO window on one half of ODM, only 3 pipes should
be allocated and scaling parameters adjusted to handle this case.
Otherwise, we use 4 pipes.
Move copy_surface_update_to_plane() before dc_add_plane_to_context()
so that it gets the updated rect information when setting up
the pipes.
Add dc_check_boundary_crossing_for_windowed_mpo_with_odm() to force
a full update when we cross a boundary requiring us to reconfigure
the number of pipes between 3 and 4 pipes.
Set config.enable_windowed_mpo_odm to true when we have the
debug.enable_single_display_2to1_odm_policy set to true.
Don't fail validating ODM with windowed MPO if
config.enable_windowed_mpo_odm is true.

[Description]
Exit SubVP if MPO is in use since SubVP + MPO together is not supported.
- Don't add SubVP at validation time if we see MPO is in use
Issues fixed in the SubVP / MPO transition:
1. Enable phantom pipes in post unlock function to prevent underflow
when an active pipe is being transitioned to be a phantom pipe (VTG
updates take place right away). Also must wait for VUPDATE of the main
pipe to complete first
2. Don't wait for MPCC idle when transitioning a phantom pipe to an
actual pipe. MPCC_STATUS is never asserted due to OTG being off for
phantom pipes
3. When transitioning an active pipe to phantom, program DET right away
(same as disabling the pipe) or the DET update will only take when
the phantom pipe is enabled which can cause DET allocation errors.
4. For K1/K2 programming of phantom pipes, use same settings as the
main pipe. Also don't program K1 / K2 = 0xF ever since the field is only
1 / 2 bits wide.

Set the default policy for single display use case to use 2 to 1 ODM combine.

[Why]
Uninitialized variable causes diag compilation build failure.
[How]
- Ensure that variable in question is always initialized before being
used.
- The variable in question is the USB4 DP training pattern. In case an
unsupported training pattern has been requested, update status
accordingly and abort current link training attempt.

[Why]
For some customer blending transition cases, the
available pipe for second stream is a pipe index that is
greater than the number of timing generators, which
can cause a problem in acquire_first_free_pipe since it
assumes same index for pipe and timing generator
[How]
Added logic to use last timing generator index
if the pipe index is greater than number of timing generators.

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