      2  1.1  mrg DRM README file
      3  1.1  mrg 
      4  1.1  mrg 
      5  1.1  mrg There are two main parts to this package: the DRM client library/interface
      6  1.1  mrg (libdrm.so) and kernel/hardware-specific device modules (such as i915.ko).
      7  1.1  mrg 
      8  1.1  mrg 
      9  1.1  mrg 
     10  1.1  mrg Compiling
     11  1.1  mrg ---------
     12  1.1  mrg 
     13  1.1  mrg By default, libdrm and the DRM header files will install into /usr/local/.
     14  1.1  mrg If you want to install this DRM to replace your system copy, say:
     15  1.1  mrg 
     16  1.1  mrg 	./configure --prefix=/usr --exec-prefix=/
     17  1.1  mrg 
     18  1.1  mrg Then,
     19  1.1  mrg 	make install
     20  1.1  mrg 
     21  1.1  mrg 
     22  1.1  mrg To build the device-specific kernel modules:
     23  1.1  mrg 
     24  1.1  mrg 	cd linux-core/
     25  1.1  mrg 	make
     26  1.1  mrg 	cp *.ko /lib/modules/VERSION/kernel/drivers/char/drm/
     27  1.1  mrg 	   (where VERSION is your kernel version: uname -f)
     28  1.1  mrg 
     29  1.1  mrg Or,
     30  1.1  mrg 	cd bsd-core/
     31  1.1  mrg 	make
     32  1.1  mrg 	copy the kernel modules to the appropriate place
     33  1.1  mrg 
     34  1.1  mrg 
     35  1.1  mrg 
     36  1.1  mrg Tips & Trouble-shooting
     37  1.1  mrg -----------------------
     38  1.1  mrg 
     39  1.1  mrg 1. You'll need kernel sources.  If using Fedora Core 5, for example, you may
     40  1.1  mrg    need to install RPMs such as:
     41  1.1  mrg 
     42  1.1  mrg 	kernel-smp-devel-2.6.15-1.2054_FC5.i686.rpm
     43  1.1  mrg 	kernel-devel-2.6.15-1.2054_FC5.i686.rpm
     44  1.1  mrg 	etc.
     45  1.1  mrg 
     46  1.1  mrg 
     47  1.1  mrg 2. You may need to make a symlink from /lib/modules/VERSION/build to your
     48  1.1  mrg    kernel sources in /usr/src/kernels/VERSION (where version is `uname -r`):
     49  1.1  mrg 
     50  1.1  mrg 	cd /lib/modules/VERSION
     51  1.1  mrg 	ln -s /usr/src/kernels/VERSION build
     52  1.1  mrg 
     53  1.1  mrg 
     54  1.1  mrg 3. If you've build the kernel modules but they won't load because of an
     55  1.1  mrg    error like this:
     56  1.1  mrg 
     57  1.1  mrg 	$ /sbin/modprobe drm
     58  1.1  mrg 	FATAL: Error inserting drm (/lib/modules/2.6.15-1.2054_FC5smp/kernel/drivers/char/drm/drm.ko): Invalid module format
     59  1.1  mrg 
     60  1.1  mrg    And 'dmesg|tail' says:
     61  1.1  mrg 
     62  1.1  mrg 	drm: disagrees about version of symbol struct_module 
     63  1.1  mrg 
     64  1.1  mrg    Try recompiling your drm modules without the Module.symvers file.
     65  1.1  mrg    That is rm the /usr/src/kernels/2.6.15-1.2054_FC5-smp-i686/Module.symvers
     66  1.1  mrg    file (or rename it).  Then do a 'make clean' before rebuilding your drm
     67  1.1  mrg    modules.
