From: Eric Anholt Date: Thu, 23 May 2013 23:08:22 +0000 (-0700) Subject: intel: Extend the force_y_tiling flag to allow forcing no tiling. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=da2880bea05bfc87109477ab026a7f5401fc8f0c;p=mesa.git intel: Extend the force_y_tiling flag to allow forcing no tiling. For a blit-uploaded temporary, it's faster on current hardware to memcpy the data into a linear CPU mapping than to go through the GTT. v2: Turn the not-fully-supported mask into 3 supported enum values.
