Kristian Høgsberg dccefba71a Take bo type argument out of the ioctl interface. 
The buffer object type is still tracked internally, but it is no longer
part of the user space visible ioctl interface.  If the bo create ioctl
specifies a non-NULL buffer address we assume drm_bo_type_user,
otherwise drm_bo_type_dc.  Kernel side allocations call
drm_buffer_object_create() directly and can still specify drm_bo_type_kernel.
Not 100% this makes sense either, but with this patch, the buffer type
is no longer exported and we can clean up the internals later on.

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.
