4 years agost/mesa: Skip scissor rect updates when scissor is entirely disabled.
Kenneth Graunke [Wed, 31 Jul 2019 01:07:17 +0000 (18:07 -0700)]
st/mesa: Skip scissor rect updates when scissor is entirely disabled.

If any scissor rectangles are enabled, then we need to set proper
scissor rectangles for all viewports.  But if the scissor test is
entirely disabled, then we can skip updating any scissor rectangles.

Without this step, we were updating the scissor rectangles based on
the current framebuffer size.  So if an app rendered to a variety of
render targets at different sizes, with scissor test disabled each
time, we'd still be continually updating the scissor rectangles,
even though it's not necessary.

In Civilization VI, this drops us from 310-350 set_scissor_state
calls per frame to 0, as it doesn't appear to use scissor testing.

4 years agointel/fs: Use ALIGN16 instructions for all derivatives on gen <= 7
Jason Ekstrand [Thu, 25 Jul 2019 23:28:44 +0000 (18:28 -0500)]
intel/fs: Use ALIGN16 instructions for all derivatives on gen <= 7

The issue here was discovered by a set of Vulkan CTS tests:

    dEQP-VK.glsl.derivate.*.dynamic_*

These tests use ballot ops to construct a branch condition that takes
the same path for each 2x2 quad but may not be uniform across the whole
subgroup.  They then tests that derivatives work and give the correct
value even when executed inside such a branch.  Because the derivative
isn't executed in uniform control-flow and the values coming into the
derivative aren't smooth (or worse, linear), they nicely catch bugs that
aren't uncovered by simpler derivative tests.

Unfortunately, these tests require Vulkan and the equivalent GL test
would require the GL_ARB_shader_ballot extension which requires int64.
Because the requirements for these tests are so high, it's not easy to
test on older hardware and the bug is only proven to exist on gen7;
gen4-6 are a conjecture.
