No DRM kernel support for i830 ?

[Alexey D. <da...@ns...>]

Hi there,

Judging from /sys/dev/drm/ contents, and listed kernel options in NOTES,
there's currently evidence of support for i810/830 chips in FreeBSD,
which (I suspect) is the probable reason why DRI is not enabled on my
box (FreeBSD 5.2-CURRENT from yesterday, latest X.Org).  I also found
traces of i810/830 support in FDo CVS
(http://freedesktop.org/cgi-bin/viewcvs.cgi/dri/drm/bsd/i830/),
getting me to the fact that i8x0 files were removed from the BSD side,
since they were not actually ported.  (Unfinished? broken? unstable?)

Googling also revealed that back in 2002, someone (namely, moto kawasaki
<kaw...@mb...>) was compiling FreeBSD's DRM with signs of
i830 in it
(https://lists.csociety.org/pipermail/freebsd-xfree86/2002-April/000189.html):

I would be most grateful to anyone that could shine a bit of light on
current situation, or at least give authoritative and complete answer on
whether I can or cannot use DRM/DRI on FreeBSD with i830 for today.

On Eric's page (http://people.freebsd.org/~anholt/dri/) there's a TODO
item that says "Port the i810 driver".  What is current status of this
item?  Is there anything I can help with?

In case there something that can be done to hack it around and make it
work, I'd really love to hear how.  (Maybe there some untested or broken
patches are floating around that one can make use of.)

Thanks in advance.  Any information/pointers are most welmome.
