In use cases with very high graphics for some time followed by
low constant usage, the power level is never dropped. Periodically
allow the TZ algorithm to run to see if any change in the external
conditions has occured.

In some situations, the same block of memory is
mapped multiple times. Properly refcount that mapping
otherwise we could get into a situation where the mem
entry is completely dereferenced before its time.

If the GPU is running as slowly as possible, it is adding
lots of io busy to the CPU. This causes the CPU ondemand
algorithm to unneccessarily increase CPU frequency.

Actually vote for AXI rate. If gpuclk sysfs file is changed
during device sleep, the previous AXI rate was retained instead
of the new AXI rate.

Distinguish between similar clocks on different cores using the
device struct passed to clk_get(). This allows for a common
clock naming convention that spans across targets.

Fix a bug in the interaction between NAP and GPU DCVS. Without
this change the clock freq recommended by DCVS might or might
not have been used. Power levels should be stabilized for test
cases now.

The workaround added to prevent the writes to ringbuffer WPTR from being
dropped does not work on a22x GPU. So, restrict this workaround only for
a20x GPU.

Sometimes, the writes to ringbuffer WPTR register are dropped. This will
make the GPU to go to idle before completing all the commands that it is
submitted with. This workaround prevents the writes from being dropped.

The buffers memstore and dummyspace were being memset

These are changes to the cffdump output format.
MEMORY_BASE reports the address range we're using at the start
of the dump, which helps the postprocessors validate memory
writes.
HANG is emitted at the start of kgsl_postmortem_dump(), and can
be used by the postprocessors to stop when the hang occurs.

If a major GPU fault occurs, interrupts should be turned off to

We cannot assume that a VMA region created as a result of an mmap
