| # 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" |
