# 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.linux file 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 -f Makefile.linux 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 -f Makefile.linux r128.o radeon.o
|
|
#
|
|
# or:
|
|
#
|
|
# make -f Makefile.linux DRM_MODULES="r128 radeon"
