From e179fee049da7b880dfef6f71d2919f90b3dae4e Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Mon, 27 Jun 2016 15:24:36 -0700 Subject: [PATCH] anv/blit2d: Copy with stencil sources when needed In the next patch, ISL will unconditionally perform verification of a surface's tiling and usage. Since it will require that w-tiled images be stencil buffers, create a stencil surface to copy from a w-tiled/stencil surface.
