Subject: i965: Set UniformBufferOffsetAlignment to sizeof(vec4)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f29ab4ece5b6a0321f5e4a6fafb7ecacf7214044;p=mesa.git

i965: Set UniformBufferOffsetAlignment to sizeof(vec4)

This matches the behavior of the Windows driver, but a bspec reference
should would be nice.

NOTE: This is a candidate for the 9.0 and 9.1 branches.
