Owain G. Ainsworth 13ff0e58c3 Remove drmModeReplaceFb after it was removed from the kernel.
It is impossible to replace the original semantics of this call purely
in userland, since the fb_id would change.

README

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.
