From ac066bf65cb585a4f6b4a2fb1d055b033f2b94ae Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 9 Sep 2015 15:52:08 +0200 Subject: [PATCH] nv30: Fix color resolving for nv3x cards We do not have a generic blitter on nv3x cards, so we must use the sifm object for color resolving. This commit divides the sources and dest surfaces in to tiles which match the constraints of the sifm object, so that color resolving will work properly on nv3x cards.
