[Mesa-dev] [PATCH 0/7] u_queue fence patches and a radeonsi fix

[Nicolai Hähnle]

Hi all,

Another multi-threading bug I ran into, this time with radeonsi shader
fences.

Patches 1-5 make util_queue_fence more widely usable, and include an
optional futex-based implementation. The patches themselves are on top
of the simple-mutex patches, but could easily be removed to drop the
futex stuff (though the memory improvements are a pretty strong
argument).

Please review!
Thanks,
Nicolai
