TCCNTLREG contains additional L3 cache write merging optimizations.
The default value on my system appears to be:
- URB Partial Write Merging (bit 0)
- L3 Data Partial Write Merging (bit 2)
- TC Disable (bit 3)
Windows drivers appear to set bit 1 as well to enable "Color/Z Partial
Write Merging". This should solve an issue we were seeing where MRT
benchmarks were using substantially more bandwidth than they ought.
However, we have not observed it to cause measurable FPS gains.
It is unclear whether we should be setting bit 0 or bit 3, so for now
we leave those at the hardware default value.

Improves performance in Manhattan 3.0 by 6% on ICL 8x8 at a fixed

at out-of-the-box power management settings, however.

This makes simple_mtx_destroy set the counter to an invalid canary
value and then makes lock/unlock assert that the value is legal.
That way, calling lock/unlock after destroy will assert fail,
rather than deadlocking or potentially even working.
This has caught real deadlocks in dEQP multithreaded tests (in st/mesa
shader variant zombie list handling), which have since been fixed.

In particular, we need to invalidate the LRZ state when we cannot be
confident in what the Z state would be during rendering:
1) depth test modes not supported by LRZ
2) stencil test, which would require full rasterization and stencil
test in the binning pass (whereas LRZ normally just needs to
determine the min and max z value in an 8x8 quad)

Maybe finer way of dealing with this requirement would be to increase
the number of pdevice->memory.types[] to add a category for special
alignment cases.
Meanwhile this fixes the problem of CCS surface alignment and it's
probably not going to cause issues given the size of our address
space.

For depth+stencil images, the driver might use an optimized path
if only one aspect is cleared. It either clears the depth or the
stencil part of HTILE. Because the two separate aspects might use
the same HTILE memory we have to synchronize.

PA_SC_AA_CONFIG might be updated when conversative rasterization is
enabled. Because the driver only re-emits the multisample state if
the number of samples is different, that register value might not
be updated correctly.

Previously the flush was done before the call to st->flush but
could lead to problems as FLUSH_VERTICES could push some work
that would change the backbuffer (or modify it).
With this commit, all the backbuffer flushing code is executed
right before the call to st_flush.

The new callback is called right before the flush is done to allow
users of st->flush to do some work after all the previous work has
been flushed.
This will be used by dri_flush in the next commit.
