From 51ab7ba2673758561074184795bba5bac780a038 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 18 May 2012 15:40:33 +0100 Subject: drm/prime: introduce sg->pages/addr arrays helper the ttm drivers need this currently, in order to get fault handling working and efficient. It also allows addrs to be NULL for devices like udl.
