Author: dumbbell Date: Sun Dec 8 14:21:54 2013 New Revision: 259101 URL: http://svnweb.freebsd.org/changeset/base/259101 Log: drm/radeon: agp_info->ai_aperture_size is in bytes, not Mbytes This fixes radeon_agp_init() and gtt_size is now correct. However, this is not enough to make Radeon AGP cards work: ttm_agp_backend.c isn't implemented yet.
