Our ultimate goal is to align closely with the Linux graphics
development community and collaborate with Intel, ATI, and others on
keeping FreeBSD up to date in their product development efforts.
The focus and priority of the i915 driver is obviously Linux, but I
don't see us rejecting patches that help FreeBSD if the patches
generally make sense and don't interfere with the main priority.
What I don't really like is the old approach of trying to abstract away
differences between Linux and *BSD in drmP.h with some screaming macros.
Given the imbalance of manpower between Linux and *BSD I think the best
(and probably only really) approach is to have linux compat types and
wrapper functions for everything. Which seems to be the new plan.
If there's stuff needed above&beyond that I think we need to look at in on
a case-by-case basis and figure out what makes sense. For me the crucial
bit isn't so much whether we need to make changes in upstream linux or
not, but whether there's a benefit for usptream too. If bug reports and
bugfixes flow back to linux, then I'm all for it. If it's a one-way street
then frankly I don't care ;-)
FWIW, this is the approach I have taken with Solaris. It's probably
only a 90-95% solution at this time, but that's a hellavalot less work
than it previously was (though requiring one hellavalot of initial work
:^P ).
Cheers!
