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.
Patch 3: Don't forget to set the name of the boot perf level.
