linux-toradex.git/drivers/gpu/drm/radeon/radeon_object.c, branch v4.9 Linux kernel for Apalis and Colibri modules drm/drivers: add support for using the arch wc mapping API. 2016-10-26T06:48:01+00:00 Dave Airlie airlied@redhat.com 2016-10-24T05:37:48+00:00 7cf321d118a825c1541b43ca45294126fd474efa This fixes a regression in all these drivers since the cache mode tracking was fixed for mixed mappings. It uses the new arch API to add the VRAM range to the PAT mapping tracking tables.
