From: Jason Ekstrand Date: Thu, 9 Jun 2016 20:56:16 +0000 (-0700) Subject: anv,isl: Lower storage image formats in anv X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d82322eb188f258a7dca9ea2b59cc0332dbc4d61;p=mesa.git anv,isl: Lower storage image formats in anv ISL was being a bit too clever for its own good and lowering the format for us. This is all well and good *if* we always want to lower it. However, the GL driver selectively lowers the format depending on whether the surface is write-only or not.
