commit 3214a27b5ba7cd621b091f1d0702e069a750c054 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jan 13 09:17:29 2015 +0000 igt/gem_mmap_wc: Reorder gem_close() Unlike a GTT mmap, a WC mmap does not have a direct reference to the object, only to the backing storage. If we want to control the domain correctly for mmap(wc), we have to keep the bo reference around.
