8 years agonir/algebraic: Optimize common array indexing sequence
Ian Romanick [Wed, 20 Jul 2016 00:47:38 +0000 (17:47 -0700)]
nir/algebraic: Optimize common array indexing sequence

Some shaders include code that looks like:

   uniform int i;
   uniform vec4 bones[...];

   foo(bones[i * 3], bones[i * 3 + 1], bones[i * 3 + 2]);

CSE would do some work on this:

   x = i * 3
   foo(bones[x], bones[x + 1], bones[x + 2]);

The compiler may then add '<< 4 + base' to the index calculations.
This results in expressions like

   x = i * 3
   foo(bones[x << 4], bones[(x + 1) << 4], bones[(x + 2) << 4]);

Just rearranging the math to produce (i * 48) + 16 saves an
instruction, and it allows CSE to do more work.

   x = i * 48;
   foo(bones[x], bones[x + 16], bones[x + 32]);

So, ~6 instructions becomes ~3.

Some individual shader-db results look pretty bad.  However, I have a
really, really hard time believing the change in estimated cycles in,
for example, 3dmmes-taiji/51.shader_test after looking that change in

i965/fs: Estimate maximum sampler message execution size more accurately.

The current logic used to determine the execution size of sampler
messages was based on special-casing several argument and opcode
combinations, which unsurprisingly missed the possibility that some
messages could exceed the payload size limit or not depending on the
number of coordinate components present.  In particular:

 - The TXL, TXB and TEX messages (the latter on non-FS stages only)
   would attempt to use SIMD16 on Gen7+ hardware even if a shadow
   reference was present and the texture was a cubemap array, causing
   it to overflow the maximum supported sampler payload size and
   crash.

 - The TG4_OFFSET message with shadow comparison was falling back to
   SIMD8 regardless of the number of coordinate components, which is
   unnecessary when two coordinates or less are present.

Both cases have been handled incorrectly ever since cubemap arrays and
texture gather were respectively enabled (the current logic used by
the SIMD lowering pass is almost unchanged from the previous no16
fall-back logic used pre-SIMD lowering times).

Fixes the following GL4.5 conformance test on Gen7-8 (the bug also
affects Gen9+ in principle, but SKL passes the test by luck because it
manages to use the TXL_LZ message instead of TXL):

mesa: change state query return value for RGB565

The GL_BGR and GL_UNSIGNED_SHORT_5_6_5_REV are not defined anywhere in
OpenGL ES 3.2 (or earlier) specification, and there are no known extensions
in the Khronos registry that would add these enums as valid responses for

Note that this patch does not change the bit layout returned by the query. As
defined by the GL spec, the bit layout of GL_RGB + GL_UNSIGNED_SHORT_5_6_5 and
GL_BGR + GL_UNSIGNED_SHORT_5_6_5_REV are identical.

Anuj Phogat [Tue, 9 Aug 2016 22:41:24 +0000 (15:41 -0700)]
i965: Change 8x multisample positions

There are no standard sample positions defined in OpenGL and OpenGL
ES specs. Implementations have the freedom to pick the positions
which give plausible results. But the Vulkan 1.0 spec does define
standard sample positions for different sample counts. Defined
positions in Vulkan for all the sample counts except 8X match with
the positions we set in i965. We have an upcoming plan to share the
blorp code between OpenGL and Vulkan driver in near future. Keeping
the 8X sample positions same on both the drivers will help us move
in that direction.

Here is an argument by Neil Roberts (from commit 20250e85) against
any advantage of current 8X sample positions over the new ones:

"The comment above for the 8x sample positions says that the hardware
implements centroid interpolation by picking the centre-most sample
that is inside the primitive. That implies that it might be worthwhile
to pick a pattern that includes 0.5,0.5. However by experimentation
this doesn't seem to actually be the case. With the sample positions
in this patch, if I modify the piglit test below so that it instead
reports the centroid position, it reports 0.492188,0.421875 which
doesn't match any of the positions. If I modify the sample positions
so that they include one at exactly 0.5,0.5 it doesn't help and it
reports another position which is even further from the center for
some reason.

arb_gpu_shader5-interpolateAtSample-different

Kenneth Graunke experimented with some other patterns that have a
higher standard deviation but I think after some discussion it was
decided that it would be better to pick the same pattern as the other
graphics API in case there are games that rely on this pattern."

glsl: Fix invariant matching in GLSL 4.30 and GLSL ES 1.00.

Old languages (GLSL <= 4.20 and GLSL ES 1.00) require "invariant"
to be specified on both inputs and outputs, and match when linking.

New languages only allow outputs to be qualified as "invariant"
and remove the "invariant must match" restriction when linking
varyings (because no input can have that qualifier).

Commit 426a50e2089b12d33f5c075aa5622f64076914a3 introduced the new
behavior for ES 3.00.  It also removed the "must match" restriction
for ES 1.00 shaders, which I believe is incorrect.  This patch adds
that back, as well as making 4.30+ follow the new rules.
