You probably won't like this answer. The patches have been tested against the 2.6.34 kernel that Intel provides for KNC (found here http://software.intel.com/en-us/forums/topic/278102 ) perf stat, perf record, and PAPI have all been tested and work. The patches I've sent are the 2.6.34 ones forward ported to the 3.7-rc1 kernel. I haven't been able to run a 3.7-rc kernel on the KNC board, because there are other patches to mainline needed to get KNC running and they'd all have to be forward-ported from 2.6.34. Since the knc pmu driver closely models the p6 one, it was straightforward to use it as a basis for the forward port. Everything _should_ work but I've only compile tested.
