From 32331a3efcdd3e7f9277d13799b7914a72012fce Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Wed, 23 May 2018 15:50:14 -0700 Subject: [PATCH] i965/miptree: Drop an if case from retile_as_linear Drop an if statement whose predicate never evaluates to true. row_pitch belongs to a surface with non-linear tiling. According to isl_calc_tiled_min_row_pitch, the pitch is a multiple of the tile width. By looking at isl_tiling_get_info, we see that non-linear tilings have widths greater than or equal to 128B.
