Jesse Barnes 3cb8acd5ab Disambiguate planes & pipes for swap operations 
This mod makes the SAREA track plane to pipe mappings and corrects the name of
the plane info variables (they were mislabeled as pipe info since until now all
code assumed a direct mapping between planes and pipes).

It also updates the flip ioctl argument to take a set of planes rather than
pipes, since planes are flipped while pipes generate vblank events.

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.
