f943047e48 panfrost: Decode render target swizzle/channels
On MRT-capable systems, the framebuffer format is encoded as a 64-bit
word in the render target descriptor. Previously, the two 32-bit
words were exposed as opaque hex values. This commit identifies a 12-bit
Mali swizzle and a 2-bit channel counter, removing some of the magic. It
also adds decoding support for the AFBC and MSAA enable bits, which were
already known but otherwise ignored in pandecode.

c6be9969d2 panfrost/midgard: Add fround(_even), ftrunc, ffma
These ops were discovered by invoking the correspondingly names GLSL
functions. The rounding ops here behave exact as expected and are mapped
to their corresponding NIR ops where applicable. The ffma behaves as a
LUT instruction and requires some special argument packing (since
Midgard normally only allows for 2 arguments); this quirk will be
addressed in the future, but for now FMA is still lowered.

77fea552f6 panfrost: Use tiler fast path (performance boost)
For reasons that are still unclear (speculation included in the comment
added in this patch), the tiler? metadata has a fast path that we were
not enabling; there looks to be a possible time/memory tradeoff, but the
details remain unclear.

Regardless, this patch improves performance dramatically. Particular
wins are for geometry-heavy scenes. For instance, glmark2-es2's
Phong-shaded bunny, rendering at fullscreen (2400x1600) via GBM, jumped
from ~20fps to hitting vsync cap at 60fps. Gains are even more obvious
when vsync is disabled, as in glmark2-es2-wayland.

With this patch, on GLES 2.0 samples not involving FBOs, it appears
performance is converging with (and sometimes surpassing) the blob.

743700be1f nir/builder: Don't emit no-op swizzles
The nir_swizzle helper is used some on it's own but it's also called by
nir_channel and nir_channels which are used everywhere.  It's pretty
quick to check while we're walking the swizzle anyway whether or not
it's an identity swizzle.  If it is, we now don't bother emitting the
instruction.  Sure, copy-prop will clean it up for us but there's no
sense making more work for the optimizer than we have to.

get_intrinsic(intrinsic, index).  This makes slightly more convenient
to check the resulting loads/stores/copies, since in most tests we

but for such tests this is not a problem.

Added the ASSERT_EQ() on count to some tests missing it, so the
indices queried are always expected to find something.

Also, drop two nir_print_shader leftover calls in a test.

fdcb9779d9 nir/copy_prop_vars: keep track of components in copy_entry
When a copy_entry is SSA, store not only the nir_ssa_def* for each
component, but also the source component they come from.  At the
moment this is always a match (i.e. 'component[i] == i'), because all
the operations for a copy_entry happen using definitions with the same
size.  This prepares the code for array_derefs of vectors, in which
'component[i] != i'.

Also, extract setting all SSA components into a function of its own.

For now these derefs are not handled, so don't let these get into the
copies list -- which would cause wrong propagations.  For load_derefs,
do nothing.  For store_derefs, invalidate whatever the store is
writing to.  For copy_derefs, invalidate whatever the copy is writing
to.

enough to get optimized by copy_prop_vars.

4f917e6a61 anv: advertise 8 subpixel precision bits
On one side, when emitting 3DSTATE_SF, VertexSubPixelPrecisionSelect is
used to select between 8 bit subpixel precision (value 0) or 4 bit
subpixel precision (value 1). As this value is not set, means it is
taking the value 0, so 8 bit are used.

On the other side, in the Vulkan CTS tests, if the reference rasterizer,
which uses 8 bit precision, as it is used to check what should be the
expected value for the tests, is changed to use 4 bit as ANV was
advertising so far, some of the tests will fail.

So it seems ANV is actually using 8 bits.

v2: explicitly set 3DSTATE_SF::VertexSubPixelPrecisionSelect (Jason)

v3: use _8Bit definition as value (Jason)

v4: (by Jason)
anv: Explicitly set 3DSTATE_CLIP::VertexSubPixelPrecisionSelect

one in 3DSTATE_SF.

e03be78252 intel/fs: Implement extended strides greater than 4 for IR source regions.
Strides up to 32B can be implemented for the source regions of most
instructions by leveraging either the vertical or the horizontal
stride of the hardware Align1 region.  The main motivation for this is
that currently the lower_integer_multiplication() pass will happily
double the stride of one of the 32-bit sources, which can blow up if
the stride of the original source was already the maximum value
allowed by the hardware.

An alternative would be to use the regioning legalization pass in
order to lower such strides into the composition of multiple legal
strides, but that would be somewhat less efficient.

This showed up as a regression from my commit cbea91eb57
in Vulkan 1.1 CTS tests on CHV/BXT platforms, however it was really a
pre-existing problem that had affected conformance on other platforms
without native support for integer multiplication.  CHV/BXT were
getting around it because the code I removed in that commit had the
"fortunate" side effect of emitting narrower regions that didn't hit
the hardware stride limit after lowering.  Beyond fixing the
regression this fixes ~90 additional Vulkan 1.1 subgroup CTS tests on
ICL (that's why this patch is marked for inclusion in mesa-stable even
though the original regressing patch was not).

According to Jason, a nearly equivalent change had been committed
previously as e8c9e65185 and then (mistakenly?) reverted as
a31d038208.

This is required in combination with the following commit, because
otherwise if a source region with an extended 8+ stride is present in

emitting code that attempts to write to such a region, even though
strides greater than four are still illegal for the destination.

e2f475ddff intel/fs: Lower integer multiply correctly when destination stride equals 4.
Because the "low" temporary needs to be accessed with word type and
twice the original stride, attempting to preserve the alignment of the
original destination can potentially lead to instructions with illegal
destination stride greater than four.  Because the CHV/BXT alignment
restrictions are now being enforced by the regioning lowering pass run
after lower_integer_multiplication(), there is no real need to
preserve the original strides anymore.

Note that this bug can be reproduced on stable branches, but
back-porting would be non-trivial, because the fix relies on the
regioning lowering pass recently introduced.

c3c27762f7 intel/fs: Exclude control sources from execution type and region alignment calculations.
Currently the execution type calculation will return a bogus value in
cases like:

  mov_indirect(8) vgrf0:w, vgrf1:w, vgrf2:ud, 32u

Which will be considered to have a 32-bit integer execution type even
though the actual indirect move operation will be carried out with
16-bit precision.

Similarly there's no need to apply the CHV/BXT double-precision region
alignment restrictions to such control sources, since they aren't
directly involved in the double-precision arithmetic operations
emitted by these virtual instructions.  Applying the CHV/BXT
restrictions to control sources was expected to be harmless if mildly
inefficient, but unfortunately it exposed problems at codegen level
for virtual instructions (namely the SHUFFLE instruction used for the
Vulkan 1.1 subgroup feature) that weren't prepared to accept control
sources with an arbitrary strided region.
