Additional to that patch we still need a minor fix to mesa (just move
freeing the VM range after closing the handle). Going to send that in the
next minute to the mesa-dev list.
Otherwise the patch indeed fixes the problem, but also isn't the best idea
for performance.
Cheers,

This does not impact performance, it's all about destroying bo/va so
it's not a performance path. Or am i missing something here ?
radeonsi currently allocates very small BOs (8-32 bytes) for T#
descriptors, and throws them away immediately after drawing.
That alone of course is insane under a performance aspect, but waiting
for the last job to finish makes things completely worse.
It just moves my priorities of hacking on radeonsi a bit around.
Christian.
