From: Eric Anholt Date: Wed, 20 Mar 2013 17:46:20 +0000 (-0700) Subject: i965: Make the constant surface interface take a normal byte size. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2f41a601455e6e0366e28b6b84871842cb4bd341;p=mesa.git i965: Make the constant surface interface take a normal byte size. This puts the rounding-up logic into the function itself instead of all the callers having to manage it. Also drop an "unused" comment in gen4, as the stride *is* used for texbos (and will be for uniforms soon). NOTE: This is a candidate for the 9.1 branch.
