Description

What is DRI? See: http://dri.freedesktop.org/wiki

This is a relatively large project. It really needs someone to "step up" and "own"
this whole in-kernel driver support for X (and other graphical programs).

[Following are some notes from alanc, edited.]

One part of the task would be to update the in-kernel code:
(all relative to: http://www.illumos.org/projects/illumos-gate )
usr/src/uts/common/io/drm
usr/src/uts/intel/drm
usr/src/uts/intel/io/drm
(possibly not a complete list)

and resync it with the upstream sources:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;f=drivers/gpu/drm;hb=HEAD
(or some later version of the DRM code) Note, that code is dual-licensed.

A committed maintainer will need to subscribe to the upstream mailing list,
and may get more help there if changes start flowing both ways, instead of
just leeching off their work:
http://lists.freedesktop.org/mailman/listinfo/dri-devel

More info would be found at:

The person porting to OpenBSD gave a brief/informal talk at the
X.Org conference a few months ago on what he's had to do:

"The scariest part here, to me, is GEM. I'm totally unsure what changes
will be necessary to Illumos' virtual memory code in order for GEM to
work (and not perform embarrassingly vs Linux)." - Alex Caudill
