Subject: i965: Bump kernel requirement to 3.3 on Ivybridge.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=50e60bf8daabc473ab7caa23bb60cff8c2954d6f;p=mesa.git

i965: Bump kernel requirement to 3.3 on Ivybridge.

Kernel 3.3 introduced the SOL reset execbuf parameter, needed for GL 3.0
on Ivybridge.  Bumping the requirement will give an obvious error
message rather than simply reporting GL 2.1.
