+# 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:
+#
