Subject: i965: Move a bunch of code from intelInitContext to brwCreateContext.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fb525b87ceae543d581a5755ca547b54c58aa76;p=mesa.git

i965: Move a bunch of code from intelInitContext to brwCreateContext.

Now that intelInitContext isn't shared between i915 and i965, the split
is fairly arbitrary.  This patch moves a bunch of the basic context
creation and generation checking code up to the top-level function
(and slightly earlier).

More will follow.
