[Why]
In non-seamless pipe transitions, it can take several frames to process
a single flip. One of the reasons is the 2-step transition implementation
where first the minimal transition state is applied, then the final state
is applied, all within the same flip. This delay is noticeable to the user
in some video playback scenarios, which makes for a bad user experience.
[How]
- in applicable non-seamless cases, complete the flip with the minimal
state applied, start a counter, and create all new contexts as minimal
- if another pipe transition occurs while counting, reset the counter
- when the counter finishes, promote the current flip to a full update
and restore creation of optimized contexts
- when creating minimal states from new context, apply stream updates

[Why]
We require an interlock between driver and firmware for upcoming
features and given that this could possibly happen on any single
cursor programming call (and that we can't asynchronously wait for
firmware to respond because of it) we'd be regressing cursor performance
by at least an extra 40us per call.
When we could possibly have cursor update every 20us - 100s from high
frequency gaming mice this means that we'd be stuttering or dropping
updates and impacting overall cursor performance.
We want a solution that can:
1. Interlock between other firmware features
2. Not stall out or require the DMCUB lock for every single update
[How]
When cursor offloading is enabled and supported by an ASIC driver will
route the cursor programming through to DMU as part of the regular
DC stream cursor programming interfaces for attributes and position.
The atomic pipe programming version will not be updated: this will still
follow the existing programming path by keeping track of a field that
specifies when the register writes should be deferred to DMU.
Cursor locking is not required when cursor offload is in progress since
the updates are consolidated and processed by DMU once at the end
of the frame in a periodic manner.
The shared buffer the firmware queries from is allocated along with the
rest of the scratch state region in an area that's accessible by
both firmware and driver.
The size of the cursor offload (v1) state will not change, but it does
have a unique union per ASIC version with room for expansion if needed.
When firmware features notifying DMU of DRR updates are not enabled we
now send an explicit vtotal min/max update via driver to DMU firmware
whenever the vtotal max changes. This is to allow the cursor programming
to determine the appropriate latch update point offset from vupdate.
