From bc5ae6a330102a1ae4ef573539f79393e64bb2c0 Mon Sep 17 00:00:00 2001 From: Jonathan Marek Date: Thu, 4 Jul 2019 13:30:55 -0400 Subject: etnaviv: fix ts size calculation The size of the TS is screen->specs.bits_per_tile bits per tile, with each tile being 64 bytes of the resource. This gives the same result for 32bpp formats, but reduces the size of TS for 16bpp formats by 2.
