# Makefile -- For the Direct Rendering Manager module (drm)
#
# Based on David Woodhouse's mtd build.
#
# Modified to handle the DRM requirements and builds on a wider range of
# platforms in a flexible way by David Dawes.  It's not clear, however,
# that this approach is simpler than the old one.
#
# The purpose of this Makefile is to handle setting up everything
# needed for an out-of-kernel source build.  Makefile.kernel contains
# everything required for in-kernel source builds.  It is included into
# this file, so none of that should be duplicated here.

#
# By default, the build is done against the running linux kernel source.
# To build against a different kernel source tree, set LINUXDIR:
#
#    make LINUXDIR=/path/to/kernel/source

#
# To build only some modules, either set DRM_MODULES to the list of modules,
# or specify the modules as targets:
#
#    make r128.o radeon.o
#
# or:
#
#    make DRM_MODULES="r128 radeon"
