From cb8cdab8e8479488d4aabb2553c099f1f99c185b Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 30 May 2017 08:28:47 -0700 Subject: intel/isl: Generate phys_total_el from isl_calc_phys_extent The only surface layout for which slice0 makes any sense is GEN4_2D. Move all of the slice0 stuff into isl_calc_phys_total_extent_el_gen4_2d and make the others trivially return the total size in surface elements. As a side-effect, array_pitch_el_rows is now returned from these helpers as well.
