7 years agollvmpipe: do transpose/untwiddle after conversion for 8bit formats
Roland Scheidegger [Thu, 22 Dec 2016 02:55:17 +0000 (03:55 +0100)]
llvmpipe: do transpose/untwiddle after conversion for 8bit formats

Generally we should do tranpose after conversion, if the format has less than
32 bits per channel (if it has 32 bits, conversion is going to be a no-op
anyway...). This is obviously because there's less vectors to deal with.
Though the advantage for 16 bit formats isn't that big, and in fact with AVX
there isn't really any (as the 32bit unpacks can be done with 256bit, but
the smaller ones cannot, although that would change again with proper AVX2
support).
Only makes sense for 2d and not 1d cases. And to keep things easy, only handle
1,2 and 4 channels (rgbx is just fine).
For rgba unorm8 format the backend conversion sums up to these instruction
totals (not counting the movs for SSE2 due to 2-op syntax - generally every 2
unpacks need an additional mov).
                     SSE2                    AVX
transpose:           32 unpack               16 unpack
untwiddle:           0                       8 (128bit low/high permutes)
convert:             16 mul + 16 cvt         8 mul + 8 cvt
32->8bit:            12 pack                 8 (128bit extract) + 12 pack

When doing transpose/untwiddle afterwards we get:
convert:             16 mul + 16 cvt         8 mul + 8 cvt
32->8bit:            12 pack                 8 (128bit extract) + 12 pack
transpose/untwiddle  12 unpack               12 unpack

So for SSE2, this drops 20 unpacks (total instruction count 76->56)
whereas for AVX it replaces the 16 256bit unpacks with 8 128bit ones
and drops the 8 lo/hi permutes (in total 60->48). (Albeit to be fair,
the permutes could be dropped even when doing the transpose first,
they are extremely pointless but we'd need to be able to tell
lp_build_conv to reorder the vectors, for AVX2 we're going to need to
be able to tell lp_build_conv about ordering in any case.)

(With different ordering going into conversion, it would be possible
to do 4 unpacks + 4 pshufbs instead of 12 unpacks, but that might not
be better, and not all cpus can do it. Proper AVX2 support should eliminate
the 8 128bit extracts, reduce these 12 packs to 6 and the 12 unpacks to 2
pshufb + 2 permq ideally (+ 2 final 128bit extracts).)

7 years agogallivm: generalize 4x4f->1x16ub special case conversion

gallivm: generalize 4x4f->1x16ub special case conversion

This special packing path can be easily extended to handle not just
float->unorm8 but also float->snorm8 and uint32->uint8 and int32->int8
(i.e. all interesting cases for llvmpipe fs backend code).
The packing parts all stay the same (only the last step packing will
be signed->signed instead of signed->unsigned but luckily even sse2 can do
both).
While here also note some bugs with that (we keep the bugs identical to
what we did before on x86, albeit other archs may differ). In particular
float->unorm8 too large values will still get clamped to 0, not 255, and for
float->snorm8 NaNs will end up as -1, not 0 (but we do the clamp against 1.0
there to prevent too large values ending up as -1.0 - this is inconsistent
to unorm8 handling but is what we ended up before, I'm not sure we can get
away without it). This is quite fishy in any case as we depend on
arch-dependent behavior of the iround (my understanding is in fact with
altivec the conversion would actually saturate although I've no idea about
NaNs, so probably wouldn't need to do anything for snorm).
(There are only minimal piglit tests for unorm clamping behavior AFAICT, in
particular nothing seems to test values which are too large to be handled by
the float->int conversion.)
For uint32->uint8 we also do a min against MAX_INT, since the source for
the packs is always signed (again, on x86 - should probably be able to
express these arch-dependent bits better some day).

llvmpipe: use scalar load instead of vectors for small vectors in fs backend

llvm has _huge_ problems trying to load things like <4 x i8> vectors and
stitching such loads together to form 128bit vectors. My understanding
of the problem is that the type legalizer tries to extend that to
really a <4 x i32> vector and not a <16 x i8> vector with the 4 elements
first then followed by padding, so the shuffles for then combining things
together are more or less impossible - you can in fact see the pmovzxd
llvm generates. Pre-4.0 llvm just gives up on it completely and does a 30+
pextrb/pinsrb sequence instead.
It looks like current llvm has fixed this behavior (my guess would be
due to better shuffle combination and load/shuffle folds), but we can
avoid this by just loading as <1 x i32> values, combine that and only
cast at the end. (I suspect it might also work if we'd pad the loaded
vectors immediately before shuffling them together, instead of directly
stitching 2 such vectors together pairwise before combining the pair.
But this _might_ lose the ability to load the values directly into
their right place in the vector with pinsrd.). But using 32bit values
is probably easier for llvm as it will never give it funny ideas how
the vector should look like.
(This is possibly only a problem for 1x8bit formats, since 2x8bit will
end up fetching 64bit hence only two vectors are stitched together,
not 4, but we use the same strategy anyway.)

7 years agost/mesa: enable GLSLOptimizeConservatively for drivers that want it

st/mesa: enable GLSLOptimizeConservatively for drivers that want it

GLSL compilation now takes 24% less time with the Gallium noop driver.
I used my shader-db for the measurement. The difference for the whole
radeonsi driver can be ~10%.

The generated TGSI is mostly the same. For example, the compilation success
rate with a TGSI->GCN bytecode converter without any optimizations is
the same. Note that glsl_to_tgsi does its own copy propagation and simple
register allocation.

shader-db GCN report:
- Talos spills fewer SGPRs.
- DOTA 2 spills more SGPRs.
- The average shader-db score is better, but it's just due to randomness.
