recently started checking the size of declared LDS allocations, all shaders
involved in tesselation fail to compile on SI.

Note that the entire calculation here seems wrong, given how we calculate
indices for generic attributes, so the number ends up wrong on CI+ as well.
A proper solution is clearly needed, but this patch should serve as a band-aid
for SI in the meantime.

Also note that the real size of the LDS allocation in hardware is independent
from what we tell LLVM, so this is really more of a "cosmetic" change.

8 years agoi965: Switch to scalar TCS by default.
Kenneth Graunke [Fri, 22 Apr 2016 04:42:08 +0000 (21:42 -0700)]
i965: Switch to scalar TCS by default.

Normally, we expect SIMD8 shaders to be more instructions than SIMD4x2
shaders, as it takes four instructions to operate on a vec4, rather than
a single instruction.  However, the benefit is that it can process 8
objects per shader thread instead of 2.

Surprisingly, the shader-db statistics show an improvement in both
instruction and cycle counts:

Synmark: -31.25% instructions, -29.27% cycles, 0 hurt.
Tessmark: -36.92% instructions, -37.81% cycles, 0 hurt.
Unigine Heaven: -3.42% instructions, -17.95% cycles, 0 hurt.
Shadow of Mordor:
   +13.24% instructions (26 with fewer instructions, 45 with more),
   -5.23% cycles (44 with fewer cycles, 27 with more cycles).

Presumably, this is because the SIMD8 URB messages are a much more
natural fit than the SIMD4x2 URB messages - there's a ton less header
setup.

I benchmarked Shadow of Mordor and Unigine Heaven on my Skylake GT3e,
and the performance seems to be the same or increase ever so slightly
(< 1 FPS difference).  So I believe it's strictly superior.

There's also a lot more optimization potential we can do in scalar mode.

This will also help us finish fp64 support, as scalar support is going
to land much sooner than vec4-mode support.

freedreno: allow ctx->draw_vbo to fail

Pretty much only happens if shader variant compile fails.  But in this
case, if we haven't emitted cmdstream, we don't want to set needs_flush.

8 years agofreedreno: move shader-stage dirty bits to global dirty flag

freedreno: move shader-stage dirty bits to global dirty flag

This was always a bit overly complicated, and had some issues (like
ctx->prog.dirty not getting reset at the end of the batch).  It also
required some special hacks to avoid resetting dirty state on binning
pass.  So just move it all into ctx->dirty (leaving some free bits
for future shader stages), and make FD_DIRTY_PROG just be the union
of all FD_SHADER_DIRTY_*.
