From a9d6dd2554e35c0213382fff19f5dbf151707955 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 12 Sep 2014 14:32:40 +1000 Subject: [PATCH] drm/ast: switch to using CACHED by default for sysram This fixes problems on ppc64 platforms, where we could end up using a WC mapping for migrating BOs with memcpy, when really we want to use cached memory.
