XXX this is gets radeon working on amd64 with an older PCI 9250 card. XXX: need to excise vtophys() usage. XXX: need to finish porting these fixes to external. however, this doesn't get radeon working on amd64 here :(		2009-03-30 01:45:41 +00:00

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 i915.ko).

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:

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.
