[Nouveau] [PATCH] Add Option "DRI3" to allow to disable DRI3 under EXA.

That would be great, as long as it does only that and does not go into
the "drivername" territory. As the said driver ;-)

"A driver name to use can be provided instead
of simple boolean value, which will be passed to the GL implementation for
it to load the appropriate backend."

[Nouveau] [PATCH] Add Option "DRI3" to allow to disable DRI3 under EXA.

Erm, that's nuts. I also don't really understand what they're
talking
about there... i915g vs i915? Anyways, I just meant the version
numbers :)

[Nouveau] [PATCH] Add Option "DRI3" to allow to disable DRI3 under EXA.

The DRI option with the intel ddx can be used to indicate the following
 - whether dri is disabled
 - the dri "version" - dri1, dri2, dri3
 - the dri module name - doo_dri.so bar_dri.so

I'm not sure how exactly it's supposed to work/works, and I believe
most of that is due to legacy reasons. I'm just saying let's not do
the whole thing - just the dri "version" would be great (as you
suggested).

-Emil
