67956689bb nir: Rename replicated-result dot-product instructions
All these instructions replicate the result of a N-component dot-product
to a vec4.  Naming them fdot_replicatedN gives the impression that are
some sort of abstract dot-product that replicates the result to a vecN.
They also deviate from fdph_replicated... which nobody would reasonably
consider naming fdot_replicatedh.

Naming these opcodes fdotN_replicated more closely matches what they
are, and it matches the pattern of fdph_replicated.

I believe that the only reason these opcodes were named this way was
because it simplified the implementation of the binop_reduce function in
nir_opcodes.py.  I made some fairly simple changes to that function, and
I think the end result is ok.

The bulk of the changes come from the sed rename:

    sed --in-place -e 's/fdot_replicated\([234]\)/fdot\1_replicated/g' \
        $(grep -r 'fdot_replicated[234]' src/)

v2: Use a named parameter to binop_reduce instead of using
isinstance(name, str).  Suggested by Jason.

87934f02f9 blorp: allow blits with floating point source layers
The current blorp API only allows source layers for 3D images to be
integers. That is causing problems with the Vulkan API where we need
to be able to use a 3D layer that could be in between 2 layers.

This change allows a floating point value to be passed for blits and
internally sets up the input parameters to pass floating point values
to kernels.

aca31baafc isl: Enable Tigerlake HDC:L1 caches via MOCS in various cases.
Thanks to Felix Degrood for discovering that we missed enabling this
additional caching on Tigerlake!  Felix also benchmarked the changes.

We now use MOCS 48 (HDC:L1 + L3 + LLC) for render targets, textures,
and pull constant buffers.  We leave storage buffers & images, as well
as stateless messages, using the previous MOCS 2 value.  We can't use
HDC:L1 with atomics, and we don't know a priori whether storage buffers
will be used with atomics or not.  Similarly, the Vulkan buffer device
address feature allows atomics to be performed on buffers via stateless
messages, and we only can control MOCS at the base address level, so
we can't do much there.

This is closer to what the Windows Vulkan and OpenGL drivers do,
though it isn't quite the same - they also disable LLC in some cases,
but we observed this to have noticable performance regressions when
we tried (though a couple titles benefited).  We may try experiment
with that in the future.

Improves performance in a number of titles:

- Unreal Engine 4 Shooter Demo   [VK]: 11.8%
- Witcher 3                    [DXVK]:  3.9%
- Rise of the Tomb Raider        [VK]:  1.5%
- Shadow of the Tomb Raider      [VK]:  1.0%
- Grand Theft Auto V           [DXVK]:  0.8%

We did not observe any performance regressions.

02fe825a61 isl, anv, iris: Add a centralized helper to select MOCS based on usage
On Gen12+, we can enable additional caches in certain usage situations.
This routes that decision making to a central place in ISL, based on
surface usage flags, and updates both drivers to use it.  (i965 doesn't
need to change because it doesn't support Gen12.)

We continue handling the "external" decision via an anv_mocs() wrapper
for now, since we store that flag in anv_bo, which isl doesn't know
about.  (We could introduce an ISL_SURF_USAGE_EXTERNAL, but I'm not
actually sure that would be cleaner.)

This patch should not have any functional nor performance effects, as
we continue selecting the exact same MOCS values for now.

Also, we should avoid setting ISL_SURF_USAGE_TEXTURE_BIT for the
destination, which isn't sampled from.

dd1971c9d8 anv: Bump the number of update-after-bind descriptors to 1M
It's a bit hard to exactly map our implementation to the limits
described by Vulkan.  The bindless surface handle in the extended
message descriptors is 20 bits and it's an index into the table of
RENDER_SURFACE_STATE structs that starts at bindless surface base
address.  This means that we can have at must 1M surface states
allocated at any given time.  Since most image views take two
descriptors, this means we have a limit of about 500K image views.

However, since we allocate surface states at vkCreateImageView time,
this means our limit is actually something on the order of 500K image
views allocated at any time.  The actual limit describe by Vulkan, on
the other hand, is a limit of how many you can have in a descriptor set.
Assuming anyone using 1M descriptors will be using the same image view
twice a bunch of times (or a bunch of null descriptors), we can safely
advertise a larger limit.  1M is what's required by D3D12, so let's
advertise that.

prog_data->total_shared, which is the field that we actually use for
controlling the shared local memory size in all drivers.  We were
still using it in one place for VK_EXT_pipeline_executable_properties,
but we should just fix that and delete the field.

f8117f7051 intel/fs: Allow constant-propagation into SAMPLEINFO and IMAGE_SIZE
Without this, we end up with indirect sampler messages all the time
because we don't propagate the texture/image BTI.  This makes debugging
shaders with imageSize or textureSamples in them a pain.

such a restriction existed in the first place.

5abac85177 intel/fs: Rework scratch handling on Gen9+
The current scratch mechanism uses an MRF hack where we reserve a few
GRF registers to treat like the MRF and we collect the data into that
MRF region before doing a scratch write.  We also use that region for
the header for scratch reads.

This commit changes things and gets rid of the MRF hack.  Instead, we
reserve a single register (which RA is free to pick) for the scratch
header and uses split sends for scratch writes to avoid having to do
the copy.  This should provide RA with more freedom in the presence of
spilling as well as avoid some unnecessary data moves.  In future, the
new GEN9_SCRATCH_HEADER opcode gives us a place where we can do our own
per-thread scratch base address calculations rather than depending on
the scratch base address that gets pushed into g0.  Having an opcode for
this lets us do it once at the top of the shader rather than repeating
it at every read/write.

One other noticeable difference is the use of SHADER_OPCODE_SEND.  We
can get away with this thanks to the fact that we're now using a set to
track which instructions are generated by spills and don't rely on the
opcodes to find spill/fill instructions.  This allows us to avoid adding
more virtual opcodes and let the normal code paths handle things like
scoreboard dependencies between header setup and the SEND.  It also
means that post-RA scheduling may be able to space out the header setup
MOV and the SEND for better latency hiding.

f650c4c0c6 intel/fs/ra: Sanity-check our IP counts
Starting with e99081e76d, we don't re-construct liveness information
every time we spill a register.  Instead, we're very careful to track
which instructions are spill instructions and not contribute those to
the IP count so that we can continue to use the old liveness information
even though instructions have been added.  This commit adds an assert
that sanity-checks that we count the same number of instructions as our
liveness information is based on.

06ebf23283 intel/fs: Add a SCRATCH_HEADER opcode
This opcode is responsible for setting up the buffer base address and
per-thread scratch space fields of a scratch message header.  For the
most part, it's a copy of g0 but some messages need us to zero out g0.2
and the bottom bits of g0.5.

This may actually fix a bug when nir_load/store_scratch is used.  The
docs say that the DWORD scattered messages respect the per-thread
scratch size specified in gN.3[3:0] in the message header but we've been
leaving it zero.  This may mean that we've been ignoring any scratch
reads/writes from a load/store_scratch intrinsic above the 1KB mark.

24b64c8408 intel/fs: Copy the PTSS from g0 for scratch reads/writes
In theory, this fixes a bug where we were dropping the PTSS bound on the
floor.  The hardware docs claim that the A32 DWORD and BYTE scattered
read/write messages do a PTSS bounds check.   However, in practice, it
seems that the hardware ignores the bounds check so this doesn't
actually matter.  I verified this with the following couple of piglit
tests:

    https://gitlab.freedesktop.org/mesa/piglit/-/merge_requests/399

In practice, this prevents the next commit from making a subtle
behavioral change.
