On recent versions of DMUB firmware, if we want to completely disable
ABM we have to pass ABM_LEVEL_IMMEDIATE_DISABLE as the requested ABM
level to DMUB. Otherwise, LCD eDP displays are unable to reach their
maximum brightness levels. So, to fix this whenever the user requests an
ABM level of 0 pass ABM_LEVEL_IMMEDIATE_DISABLE to DMUB instead. Also,
to keep the user's experience consistent map ABM_LEVEL_IMMEDIATE_DISABLE
to 0 when a user tries to read the requested ABM level.

[Why]
MST relevant variables are maintained at drm side. As the result, we
still have to call drm_dp_remove_payload_part2() to update the relevant
values regardless the link is under mst mode or not. We used to have a
workaround patch to tackle this: commit 3d8fcc6740c9 ("drm/amd/display:
Extract temp drm mst deallocation wa into its own function")
Now it's time to remove the workaround and adjust the flow.
[How]
During deallocate_mst_payload(), source actually doesn't send out
ALLOCATE_PAYLOAD at the end as like the flow in allocate_mst_payload().
Call function dm_helpers_dp_mst_send_payload_allocation() at the end of
deallocate_mst_payload() is a bit confusing.
Separate dm_helpers_dp_mst_send_payload_allocation() into 2 functions.
Have a new function dm_helpers_dp_mst_update_mst_mgr_for_deallocation()
to replace dm_helpers_dp_mst_send_payload_allocation() for payload
deallocation.

Declaration of 'struct drm_device *dev' is redundant, as

On UHBR links the PBN divider is a fractional number, accordingly store
it in fixed point format. For now drm_dp_get_vc_payload_bw() always
returns a whole number and all callers will use only the integer part of
it which should preserve the current behavior. The next patch will fix
drm_dp_get_vc_payload_bw() for UHBR rates returning a fractional number
for those (also accounting for the channel coding efficiency correctly).

[WHY & HOW]
When dsc is possible, MST mode validation includes:
1. if maximum dsc compression cannot fit into end to end bw, mode pruned
2. if native bw cannot fit into end to end bw, try to enabled dsc to see
whether a feasible dsc config can be found
3. if native bw can fit into end to end bw, mode supported

For features that are implemented primarily in DMUB (e.g. PSR), it is
useful to be able to trace them at a DMUB level from the kernel,
especially when debugging issues. So, introduce a debugfs interface that
is able to read and set the DMUB trace mask dynamically at runtime and
document how to use it.

When ddc_service_construct() is called, it explicitly checks both the
link type and whether there is something on the link which will
dictate whether the pin is marked as hw_supported.
If the pin isn't set or the link is not set (such as from
unloading/reloading amdgpu in an IGT test) then fail the
amdgpu_dm_i2c_xfer() call.

The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.
And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.
v2:
- Fix DSC kunit test cases.

An assignment statement was reversed during a refactor which effectively
disabled S/G display outright. Since, we use
adev->mode_info.gpu_vm_support to indicate to the rest of the driver
that S/G display should be enabled and currently it is always set to
false. So, to fix this set adev->mode_info.gpu_vm_support's value to
that of init_data.flags.gpu_vm_support (and not vice versa).

As dc_set_power_state() no longer allocates memory, it's not necessary
to have return types and check return code as it can't fail anymore.
Change it back to `void`.

drm_atomic_helper_suspend() can return PTR_ERR(), in which case the
error gets stored into `dm->cached_state`. This can cause failures
during resume. Catch the error during suspend and fail the suspend
instead.

Add a warning if the FPU is used from any context other than task
context. This is only precaution since the code is not able to be used
from softirq while the API allows it on x86 for instance.

The fpu_recursion_depth counter is used to ensure that dc_fpu_begin()
can be invoked multiple times while the FPU-disable function itself is
only invoked once. Also the counter part (dc_fpu_end()) is ballanced
properly.
Instead of using the get_cpu_ptr() dance around the inc it is simpler to
increment the per-CPU variable directly. Also the per-CPU variable has
to be incremented and decremented on the same CPU. This is ensured by
the inner-part which disables preemption. This is kind of not obvious,
works and the preempt-counter is touched a few times for no reason.
Disable preemption before incrementing fpu_recursion_depth for the first
time. Keep preemption disabled until dc_fpu_end() where the counter is
decremented making it obvious that the preemption has to stay disabled
while the counter is non-zero.
Use simple inc/dec functions.
Remove the nested preempt_disable/enable functions which are now not
needed.
