XFree86 DRI on NetBSD

Erik Reid has been working on adding DRI support for NetBSD. Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware in a safe and efficient manner. Some of Erik's work has been imported into XFree86 4.3.0 which is now in xsrc tree. He has subsequently put together a fairly large patch which compiles and works on his NetBSD/i386 1.6P system with a matrox g450. Try out the patch and give him some feedback!

Hi there. For those that are interested, I've slowly been working on adding DRI
support for NetBSD in the DRI project's CVS repository. A bunch, but not all, of
this work got imported into 4.3.0. Now that 4.3.0 is in xsrc tree, I think we
should bring in what's left of the changes to make it work properly, since there's
not much that's missing.

I've put together a fairly large patch which makes it all compile and work on
my NetBSD/i386 1.6P system with a matrox g450. I haven't tested it on any other
cards, but Eric Anholt did test his cards out to see if they worked, and they did.
I believe that includes a radeon and an r128. I have no idea if the pcigart stuff
even has a hope of working at all currently.

There are a few outstanding issues that I can think of off hand:
1) kernel module is not automatically built/installed by a 'make install' in
2) kernel module is not automatically loaded by the X server
3) locators.h is not present but is included by <dev/pci/pcivar.h>
(I've just been touching it for my builds, but that's obviously not the best :)
4) I have no idea if this will work on alpha or any other port with pci. I don't have
the hardware.
5) I haven't actually tested the linux compat portion of this. I just have to build
some X 4.3.0 linux binaries, but haven't gotten around to it.

I can't think of anything else at the moment, but I'm sure there's more :)

Anyway, the patch is at http://www.canuck.com/~reide/netbsd/dri/netbsd-dri.diff.gz

Feedback, please. :)
