This patch implements preemption feature for A6xx targets, this allows
the GPU to switch to a higher priority ringbuffer if one is ready. A6XX
hardware as such supports multiple levels of preemption granularities,
ranging from coarse grained(ringbuffer level) to a more fine grained
such as draw-call level or a bin boundary level preemption. This patch
enables the basic preemption level, with more fine grained preemption
support to follow.

No postamble packets which resets perfcounters? It is necessary. Also, I
think we should disable preemption during profiling like we disable slumber.
-Akhil.
You mention that we disable slumber during profiling however I wasn't
able to find code doing that. Can you please clarify which code you are
referring to or a mechanism through which the kernel can know when we
are profiling?
Best regards,
