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