svn commit: r259367 - releng/10.0/sys/dev/drm2/radeon

[Jean-Sebastien Pedron]

Author: dumbbell
Date: Sat Dec 14 00:25:25 2013
New Revision: 259367
URL: http://svnweb.freebsd.org/changeset/base/259367

Log:
  MFC r259234:
  
  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.
