[Why & How]
There is a corner case where a single PSR panel
fails to enter idle optimizations if the panel
is not flipping (no planes or DPMS_OFF == true).
This is because the panel will not enter PSR if it's
not flipping, but this will prevent the FW idle opt
path from being executed. To handle this case we will
allow entry to idle opt from driver side even when a
PSR panel is connected under the following scenarios:
1. Only a single PSR panel is connected
2. PSR panel is not flipping

displays without PSR"
This causes flicker on a bunch of eDP panels. The info_packet code
also caused regressions on other OSes that we haven't' seen on Linux
yet, but that is likely due to the fact that we haven't had a chance
to test those environments on Linux.
We'll need to revisit this.

[why]
During minimal transition commit, the base state could be freed if it is current state.
This is because after committing minimal transition state, the current state will be
swapped to the minimal transition state and the old current state will be released.
the release could cause the old current state's memory to be freed. However dc
will derefernce this memory when release minimal transition state. Therefore, we
need to retain the old current state until we release minimal transition state.

[Why]
It's possible to skip parts of the eval and exit sequencing if we know
whether DCN is in IPS2 already or if it's committed to going to idle
and not in IPS2.
[How]
Skip IPS2 entry/exit if DMCUB is idle but the IPS2 commit is not set.
Skip the eval delay if DMCUB is already in IPS2 since we know we need
to exit.
These are turned off by default.

[Why]
Cursor updates can be preempted by queued flips in some DMs.
The synchronization model causes this to occur within the same thread
at an intermediate level when we insert logs into the OS queue.
Since this occurs on the same thread and we're still holding the lock
(recursively) the cache is coherent.
The exit sequence will run twice since we technically haven't finished
the exit the first time, so we need a way to detect and avoid the
reallow in the middle of this call to prevent the hang on the cursor
update that was preempted.
[How]
Keep a counter that tracks the depth of the exit calls. Do not reallow
until the counter is zero.

[Why]
Cursor update can be pre-empted by a request for setting target flip
submission.
This causes an issue where we're in the middle of the exit sequence
trying to log to DM, but the pre-emption starts another DMCUB
command submission that requires being out of idle.
The DC lock aqusition can fail, and depending on the DM/OS interface
it's possible that the function inserted into this thread must not fail.
This means that lock aqusition must be skipped and exit *must* occur.
[How]
Modify when we consider idle as active. Consider it exited only once
the exit has fully finished.
Consider it as entered prior to actual notification.
Since we're on the same core/thread the cached values are coherent
and we'll see that we still need to exit. Once the cursor update resumes
it'll continue doing the double exit but this won't cause a functional
issue, just a (potential) redundant operation.

Since the backup and restore for plane and stream states has

We will also move the scratch memory to struct dc instead of dc_state
to avoid needing to allocate large amounts of memory every time
we create a new DC state.

[WHY & HOW]
Update planes and stream version 3 separates FULL and FAST updates
to their own sequences. It aims to clean up frequent checks for
update type resulting unnecessary branching in logic flow. It also
adds a new commit minimal transition sequence, which detects the need
for minimal transition based on the actual comparison of current and
new states instead of "predicting" it based on per feature software
policy, i.e. could_mpcc_tree_change_for_active_pipes.
The new commit minimal transition sequence is made universal to any
power saving features that would use extra free pipes such as Dynamic
ODM/MPC Combine, MPO or SubVp. Therefore there is no longer a need to
specially handle compatibility problems with transitions among those
features as they are now transparent to the new sequence.

[WHY]
If DCN is in idle then we should not be accessing DCN registers or
it can lead to hangs.
[HOW]
Log the error and return 0 or drop the write if it's in idle.
This is skipped in the exit sequence itself since the boolean flips
before it starts.
It also does not cover accesses from external clients outside of DM/DC
like firmware or the kernel mode driver.
