Hi everyone, I would like devs to test this patch on all their cards(<nvc0) and report bugs/instability. It shouldn't ever crash (but it may not always work and return -EAGAIN). I've attached a little bash script that you need to modify according to the available perf levels. Please launch it and play, watch videos or browse the internet. Also, if you could look at the hold_spin variable and tell me how you would deal with that, it would be kind of you. The problem is that PGRAPH may take an awful lot of time to pause in certain conditions and holding the lock at this position isn't needed (as far as I can tell, the critical ressource is fifo_reassign). Martin PS: I'll be out in an hour for a week so I may be slower to answer messages.
