From: Eric Anholt Date: Fri, 25 Apr 2014 18:20:57 +0000 (-0700) Subject: i965: Move intel_region_get_tile_masks() to be a miptree function. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9791eb4280a5814de9af6d9197d947221342dc4e;p=mesa.git i965: Move intel_region_get_tile_masks() to be a miptree function. All the consumers are doing it on a miptree.
