William Cohen 2016-06-21 20:10:44 UTC Doc Text Cause: There was a mismatch in the layout of the perf data structure used by the kernel and papi.

Consequence: papi would not detect that the kernel supported userspace reads of the performance counters using the rdpmc instruction.

Fix: Rebuilt papi with libpfm-4.7 that supplies perf data structure layout that match what the kernel uses.

Result: PAPI now correctly identifies when the kernel support the fast userspace rdpmc. However, PAPI does not currently use the rdpmc mechanism to read the counters.
