Fix several typos and bugs within pmcstudy. Also highlight the one SB test

2015-12-10T01:52:29+00:00

that is failing (and is likely a problem in the actual PMC defintions). Add
to this also the -A option to run all canned tests.

Proper support of Broadwell tool by the pmc_study based on the

2015-12-09T21:49:31+00:00

Intel Itune guide for 5th generation processors. There is at least
one formula missing in that guide, which I extrapolated and put a ? by
in the help.

Update the manual page to be a bit more sane. It still

may need some work, but at least now it will read properly.
(gnn you are still on the hook to help out with this
like you committed).

Fix yet another coverty warning (missing io is NULL check) and in examining that

2015-01-27T18:56:22+00:00

warning I see yet another issue where we should be pclosing the io in the event
of the error and its a command (not fclose only).

Fix minor errors found by coverity. Thanks Gleb for

the pointers to the email!

Update the hwpmc driver to have the new type HASWELL_XEON. Also

2015-01-14T12:46:58+00:00

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 ;-)
