+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.
+
+
