Subject: i965: Enable ARB_tessellation_shader on Gen8+.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7738f3a988bfa27a7c48c364cfa2d51c0b57e5d9;p=mesa.git

i965: Enable ARB_tessellation_shader on Gen8+.

Everything is in place and I'm not aware of any further issues.

Tested with:
- Piglit
- Tessmark
- Unigine Heaven
- Shadow of Mordor
- GRID Autosport

I have patches to backport this to Haswell, Ivybridge, and Baytrail as
well (the first Intel hardware to support tessellation), but there are
still a lot of GPU hangs left to debug.  So that will come later.
