At least a bunch were unrelated. It may be hard to tell because you're not
intimately familiar with how nouveau works, as well as the various differences
across generations.

Oftentimes bugs look identical, but they turn out to be quite different. I want
every bug reporter to open a fresh bug. If it's identical, I'll mark it as a
dup. Integers are cheap, I don't think the fd.o bugtracker is going to run out
of id's too soon.

(Sorry, René, for all this spam that has been thrust upon you.)

To be clear - access from multiple threads (or multiple GL contexts) isn't the
issue - it's simultaneously calling into the driver from multiple threads which
doesn't work. (The distinction may be subtle, esp to the layman, I'm just being
pedantic because GL is complicated and has lots of different usage models.)

I'd be happy to put up a statement on nouveau.freedesktop.org about the
situation if you can send me a private email (or one to the ML if you prefer)
with some specifics about what is problematic. Being unfamiliar with the Qt/KDE
world, it's not immediately apparent to me.
