Create new linux-2.6 build. Move all gpl files into the 2.6 build. If you
edit files for 2.6 be sure and break the link to the 2.4 directory and
copy the cvs history.

# 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"
