Hi!
I'd like to get an interrupt every million cache misses... to do a
printk() or something like that. As far as I can tell, modern hardware
should allow me to do that. AFAICT performance events subsystem can do
something like that, but I can't figure out where the code is / what I
should call.
Can someone help?
Thanks,
									Pavel
