DRM README file
|
|
|
|
|
|
There are two main parts to this package: the DRM client library/interface
|
|
(libdrm.so) and kernel/hardware-specific device modules (such as radeon.ko).
|
|
The kernel device modules are not shipped with libdrm releases and should only
|
|
be built from the git tree by developers and bleeding-edge testers of
|
|
non-Intel hardware. The Intel kernel modules are developed in the Linux
|
|
kernel tree.
|
|
|
|
|
|
Compiling
|
|
---------
|
|
|
|
By default, libdrm and the DRM header files will install into /usr/local/.
|
|
If you want to install this DRM to replace your system copy, say:
|
|
|
|
./configure --prefix=/usr --exec-prefix=/
|
|
|
|
Then,
|
|
make install
|
|
|
|
|
|
To build the device-specific kernel modules from the git tree:
|
|
|
|
cd linux-core/
|
|
make
|
|
cp *.ko /lib/modules/VERSION/kernel/drivers/char/drm/
|
|
(where VERSION is your kernel version: uname -f)
|
|
|
|
Or,
|
|
cd bsd-core/
|
|
make
|
|
copy the kernel modules to the appropriate place
|
|
|
|
|
|
|
|
Tips & Trouble-shooting
|
|
-----------------------
|
|
|
|
1. You'll need kernel sources. If using Fedora Core 5, for example, you may
|
|
need to install RPMs such as:
|
|
|
|
kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm
|
|
kernel-devel-2.6.15-1.2054_FC5.i686.rpm
|
|
etc.
|
|
|
|
|
|
2. You may need to make a symlink from /lib/modules/VERSION/build to your
|
|
kernel sources in /usr/src/kernels/VERSION (where version is `uname -r`):
|
|
|
|
cd /lib/modules/VERSION
|
|
ln -s /usr/src/kernels/VERSION build
|
|
|
|
|
|
3. If you've build the kernel modules but they won't load because of an
|
|
error like this:
|
|
|
|
$ /sbin/modprobe drm
|
|
FATAL: Error inserting drm (/lib/modules/2.6.15-1.2054_FC5smp/kernel/drivers/char/drm/drm.ko): Invalid module format
|
|
|
|
And 'dmesg|tail' says:
|
|
|
|
drm: disagrees about version of symbol struct_module
|
|
|
|
Try recompiling your drm modules without the Module.symvers file.
|
|
That is rm the /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686/Module.symvers
|
|
file (or rename it). Then do a 'make clean' before rebuilding your drm
|
|
modules.
