Back when SSBOs were first enabled in i965, we tried to work around
issues where the CPU and GPU were incoherently writing to the same
cacheline by forcing an alignment such that different sections of
data would fall in different cachelines. This seems wrong.
On integrated GPUs with LLC, CPU and GPU writes should be coherent.
On integrated GPUs without LLC, we either enable snooping (so they
are again coherent), or we use WC maps (so the CPU cache isn't used).
Discrete GPUs always use WC maps (so the CPU cache isn't used).
This should work. In other words, I think the increased alignment
was just working around coherency problems on atoms that have been
fixed in the intervening 6 year time period.
Untyped surface messages require 4B alignment.

This is rarely useful, but after the next patch removes tiling tracking,
this would literally be the only difference between iris_bo_alloc and

Based on a patch by Rafael Antognolli.
We already had a flags parameter, but omitted it from the simple alloc
interface because most callers were passing 0. However, we'll want to
use it for selecting between device local memory and system memory, and
possibly mmap cacheability modes, in the future. At that point, many
more callers will want to specify, so I think we should include flags
in iris_bo_alloc() as well.
A few places used the iris_bo_alloc_tiled() function simply to pass
flags, so this patch converts them to use iris_bo_alloc() instead now
it does everything they want.

Enabling this fast path, while making CPU side simpler
(and thus reducing driver's CPU overhead), forces us to
generate multiple VERTEX_BUFFER_STATE packets pointing to
the same buffer, but with slightly shifted BufferStartingAddress.
This is fine on GFX version >= 11 and < 8, but on version
8 and 9, thanks to internal details of the VF cache, vertex
data from each VERTEX_BUFFER_STATE is cached separately
and this results in a lot of cache misses.
Disabling this fast path restores previous performance levels.
On my SKL GT2 machine this improves performance in:
- GLB27 Egypt offscreen by 37%
- GLB27 TRex offscreen by 22%
- gfxbench5 Manhattan offscreen by 1.75%
- gfxbench5 Manhattan31 offscreen by 1.9%
- gfxbench5 Aztec Ruins high by 2.3%
In Intel performance CI on GFX version 9 it improves performance in:
- gfxbench5 Manhattan offscreen by 1.65%
- gfxbench5 Aztec Ruins normal offscreen by 1.33%

Now that we store shader variants in the objects themselves rather
than a per-context hash table, they are actually global across
contexts. We can enable this feature.
This makes shaders shared across contexts, so apps can compile in
one and use it in another. This has always been allowed by GL,
but in the past we've simply recompiled the shaders in every context,
which is slow and painful.

This commit enables clover support for iris. It is intended as a
compiler developer tool and not as a new OpenCL implementation from
Intel. If you want competent OpenCL, we have a different open-source
driver for that built on our LLVM-based IGC compiler stack. However,
using clover with iris is becoming increasingly useful as a compiler
development tool and I'm getting tired of carrying the patches in a
private branch.
By default, clover will not initialize on iris. To enable clover, set
the IRIS_ENABLE_CLOVER environment variable to "1" or "true". As we've
done with the semi-sketchy platform support in ANV, it dumps a very loud
WARNING to stderr when enabled. Use at your own risk.
NOTE: To anyone intending to benchmark this, the performance is going to
be terrible and that is expected. This is in no way representative of
the Intel/NIR compiler stack. As it currently stands, clover passes
-O0 to clang when compiling OpenCL C to make SPIRV-LLVM-Transator work.
When compiling the SPIR-V, clover currently doesn't run any NIR
optimizations before it lowers memory access so any NIR optimizations
iris attempts to do are severely hampered. One day, clover will get a
NIR optimization loop or the ability to hand things off to the driver
per-lowering but today is not that day.
