freebsd-skq/sys/dev/drm2/radeon/radeon_test.c
dumbbell 0d898a1422 drm/radeon: Import the Radeon KMS driver 
This driver is based on Linux 3.8 and a previous effort by kan@.

More informations about this project can be found on the FreeBSD wiki:
    https://wiki.freebsd.org/AMD_GPU

The driver is split into:

  sys/dev/drm2:
    The driver sources.

  sys/modules/drm2/radeonkmw:
    The driver main kernel module's Makefile.

  sys/modules/drm2/radeonkmsfw:
    All firmware kernel module Makefiles. There's one directory and one
    Makefile for each firmware.

  sys/contrib/dev/drm2/radeonkmsfw:
    All firmware binary sources.

  tools/tools/drm/radeon
    Tools to update firmwares or regenerate some headers.

Merging the driver to FreeBSD 9.x may be possible but not a priority for
now.
