[dtrace-discuss] Access hardware counters with DTrace

At the minute the answer is, no. However, I created a prototype
of a performance counter provider a while ago and I've (literally!)
just started another push on it. There is a placeholder RFE:

    6486156: DTrace cpc provider

If you are interested in getting some bits to play around
with, contact me off-alias.

Cheers.

Jon.
