go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE to straighten out all the missing PMCs. We also add a new pmc tool pmcstudy, this allows one to run the various formulas from the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for IB/SB and Haswell. The tool also allows one to postulate your own formulas with any of the various PMC's. At some point I will enahance this to work with Brendan Gregg's flame-graphs so we can flamegraph various PMC interactions. Note the manual page also needs some work (lots of work) but gnn has committed to help me with that ;-) Reviewed by: gnn MFC after:1 month Sponsored by: Netflix Inc.
