From bc2d6508abefb3d6f3a2188dece555ce4108d3d3 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 21 Nov 2012 10:32:36 +0100 Subject: [PATCH] drm/vmwgfx: Replace vram_size with prim_bb_mem for calculation of max resolution In the future, Scanout buffers need not be backed by VRAM and the two definitions will differ.
