[Mesa-dev] [PATCH 00/27] i965 disk shader cache

[Jordan Justen]

git://people.freedesktop.org/~jljusten/mesa i965-shader-cache-v1

The series adds support for a disk shader cache for i965, but it does
not enable it by default. To enable the i965 shader cache you need to
set the environment variable INTEL_SHADER_CACHE=1.

I don't see any regressions on Skylake with piglit and the GL CTS.

Quite some time ago I did notice a regression with Deus Ex on SKL when
the shader cache is enabled. Unfortunately, I have not been able to
make progress on this issue. HSW does *not* have the same regression
with the shader cache on Deus Ex.
