This class has code that will be shared by lower_ubo_reference and
lower_shared_reference. (lower_shared_reference will be used to
support compute shader shared variables.)
v2:
* Add lower_buffer_access.h to makefile (Emil)
* Remove static is_dereferenced_thing_row_major from
lower_buffer_access.cpp. This will become a lower_buffer_access
method in the next commit.
* Pass mem_ctx as parameter rather than using a member variable (Iago)

Let us avoid trapping in hardware from a SIGFPE and instead
assert on a zero divisor.
Hint: This can occur if a PIPE_PRIM_? is not handled in
u_prim_vertex_count() that results in ' info ' not
being initialized in the expected manner.
Further, we also fix a possibly NULL pointer dereference
from ' info ' being NULL from a u_prim_vertex_count() call.

When a buffer is created with GL_STATIC_DRAW, its contents should not
be changed frequently. But that's exactly what one application I'm
debugging does. This patch adds code to try to detect inefficient
buffer use in a couple places. The GL_ARB_debug_output mechanism is
used to report the issue.
NVIDIA's driver detects these sort of things too.
Other types of inefficient buffer use could also be detected in the
future.

This is going to require some rather intrusive kernel changes to fix
properly, in the meantime (and forever on at least pre-v4.1 kernels)
we'll have to restore the hardware defaults at the end of every batch
in which the L3 configuration was changed to avoid interfering with
the DDX and GL clients that use an older non-L3-aware version of Mesa.

The L3 state atom calculates the target L3 partition weights when the
program bound to some shader stage is modified, and in case they are
far enough from the current partitioning it makes sure that the L3
state is re-emitted.

This calculates a rather conservative partitioning of the L3 cache
based on the shaders currently bound to the pipeline and whether they
use SLM, atomics, images or scratch space. The result is intended to
be fine-tuned later on based on other pipeline state.
Note that the L3 partitioning calculated for VLV in the non-SLM non-DC
case differs from the hardware defaults in that it doesn't include a
DC partition and has twice as much RO cache space -- This is an
intentional functional change that improves performance in several
bandwidth-bound benchmarks on VLV (5% significance): SynMark
OglTexFilterAniso by 14.18%, SynMark OglTexFilterTri by 7.15%, Unigine
Heaven by 4.91%, SynMark OglShMapPcf by 2.15%, GpuTest Fur by 1.83%,
SynMark OglDrvRes by 1.80%, SynMark OglVsTangent by 1.71%, and a few
other benchmarks from the Finnish system by less than 1%.

The input of the L3 set-up code is a vector giving the approximate

Improves performance of the arb_shader_image_load_store-atomicity
piglit test by over 25x (which isn't a real benchmark it's just heavy
on atomics -- the improvement in a microbenchmark I wrote a while ago
seemed to be even greater). The drawback is one needs to be
extra-careful not to hang the GPU (in fact the whole system). A DC
partition must have been allocated on L3, the "convert L3 cycle for DC
to UC" bit may not be set, the MOCS L3 cacheability bit must be set
for all surfaces accessed using DC atomics, and the SCRATCH1 and
ROW_CHICKEN3 bits must be kept in sync.
A fairly recent kernel is required for the command parser to allow
writes to these registers.

It should be possible to use additional L3 configurations other than
the ones listed in the tables of validated allocations ("BSpec »
3D-Media-GPGPU Engine » L3 Cache and URB [IVB+] » L3 Cache and URB [*]
» L3 Allocation and Programming"), but it seems sensible for now to
hard-code the tables in order to stick to the hardware docs. Instead
of setting up the arbitrary L3 partitioning given as input, the
closest validated L3 configuration will be looked up in these tables
and used to program the hardware.
The included tables should work for Gen7-9. Note that the quantities
are specified in ways rather than in KB, this is because the L3
control registers expect the value in ways, and because by doing that
we can re-use a single table for all GT variants of the same
generation (and in the case of IVB/HSW and CHV/SKL across different
generations) which generally have different L3 way sizes but allow the
same combinations of way allocations.
v2: Use slice count from the devinfo structure instead of the gt
number to implement get_l3_way_size().
