From: Anuj Phogat Date: Thu, 16 Mar 2017 17:36:46 +0000 (-0700) Subject: i965: Delete tile resource mode code X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f5c32b07628a6ee186f130f0510bfcdafc6ce36e;p=mesa.git i965: Delete tile resource mode code Yf/Ys tiling never got used in i965 due to not delivering the expected performance benefits. So, this patch is deleting this dead code in favor of adding it later in ISL when we actually find it useful. ISL can then share this code between vulkan and GL.
