Support a new OSM sequence which optimizes the number of
instructions required to program MEM-ACC settings and
the APM configuration of the CPUSS. This frees up sufficent
space to implement the DxFSM workaround.

Program architectural register 6 with the address of the SPM
core count hysteresis register and architectural register 7
with the up and down core-count SPM hysteresis values. The
sequencer uses this information to ensure stable operation
when CPU retention or power-collapse and cluster collapse
LPMs are enabled.

Since LowSVS and SVS frequencies share the same ACC settings,
map any frequency in the LowSVS to SVS range to the same ACC
level. By doing so, the OSM device need only support 3 levels
instead of 4 thus saving sequencer instruction space. Also,
update the ACC setting to ensure bit 31 of the last ACC register
in each cluster is set when running at LowSVS/SVS frequencies.

is used by OSM to determine the APM supply for each DCVS setpoint.
The crossover corner is used by OSM to request a specific voltage

corner is requested by OSM hardware to the CPRh controller when
the VDD supply must be set to a specific voltage to ensure a stable
APM switch procedure. Define a crossover corner of 880 mV for both
VDD_APC CPR devices.

Currently power supply name is passed to get the battery profile
in of_batterydata_get_best_profile(). This creates a dependency
of waiting for the driver that has the power supply class device.
Improve this by passing the battery id directly to the API. This
way, getting battery id will be the responsibility of caller.

Instead of trying to make a decision to switch out the active
draw context for NULL at detach time leave the reference count
for it until the next context switch or until the next slumber
whichever comes first. This avoids races with the preemption
code and ensures a smooth transition.
A side effect is that we were depending heavily on the context
detach to reset the ringbuffer to the default at power down and
we didn't touch it on power up (though we did on soft reset and
wake from slumber. Curious). Obviously if we are no longer
switching we will need to force the default pagetable during start
but it seems to me like this would be the right thing to do even
if we were still switching out.

We are only writing the ringbuffer start of pipeline timestamp for
internal commands that do not have a draw context associated which
happen rarely (if ever). We should be recording the timestamp for
*ALL* commands so when something goes wrong we can get a fuller
idea of the timestamp picture for each ringbuffer.

When processing an event group we check the previously processed
timestamp to avoid going through the loop if we don't need to.
We use timestamp_cmp() to check the timestamp. In situations
where the retired timestamp has advanced by more than 0x80000000
since the last time we checked the timestamp, timestamp_cmp()
will return -1 as it thinks that the new timestamp is older than
the processed timestamp. This can happen with certain tests and
scheduling hiccups.
The event processor can be much less restrictive - all we really
care about is that the retired timestamp didn't slip backwards by
accident (highly unlikely). So just check that the last proccessed
timestamp is not equal to the retired timestamp and if the
retired timestamp has already rolled, that the delta is outside
of the 0x8000000 window.

gpuobj_free_on_fence() is used infrequently enough that it doesn't
make sense to do INIT_WORK() when the memory object is created,
especially if debug objects are enabled because INIT_WORK() will go
off and do a bunch of accounting that we don't need. Do the
INIT_WORK() just before queueing in those rare cases that this
actually happens.

Some test applications intentionally generate a GPU fault for
various reasons. Because a GPU fault generates a snapshot and
snapshots are persistent until they are pulled, running the test
application may take up the snapshot slot and prevent a real fault
from being captured and debugged.
This flag allows the draw context to intentionally avoid generating
a snapshot.
