[Nouveau] [Bug 91632] Assert in nouveau_pushbuf_data

--- Comment #8 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Unfortunately "this" issue is a lot of potential issues. The current leading
cause of such errors, assuming an up-to-date libdrm/etc, is multithreading in
the application. Nouveau does not handle this well.

I have a branch which tries to address this:

https://github.com/imirkin/mesa/commits/locking

However it's not quite there yet (although it's a good part of the way there),
and needs a rethink on some of the core mechanisms used. Unfortunately the
libdrm_nouveau api is really not well-suited to multithreading, kicks can end
up resulting implicitly from all kinds of seemingly innocuous actions.
