Linux support for various PMUs

This lists Linux support for various chips and various kernel interfaces.

There's a related list for power measurement (RAPL) support available here.

The "perf_event" column tells which Linux kernel first supported the chip using the perf_event subsystem. Note this is complicated by distributions like RHEL which backports newe CPU support back to older kernels.

The "perfctr" column says whether the current "perfctr" patch supports this chip.

The "libpfm3" and "libpfm4" columns say whether those respective libraries support the events for the chip.

The "PAPI" column says whether the current version of PAPI supports things (in general PAPI should support any chip that has both libpfm4 and perf_event support. Adding support tends to be just adding the proper preset events in the papi_events.csv file).

AMD makes this really difficult to separate the various models out. The best reference I could find is here

  1. Note that Cortex A8 and Cortex A9 processors reportedly have a bug where PMU interrupts may be lost, making perf_event usage problematic.

Notes:
  1. As shipped with PAPI
  2. Support removed in PAPI 4.0
  3. You really should be running a newer kernel, and multiplexing is still broken as of kernel 3.1. There are limitations with the MIPS implementation having to do with sched_clock() not being implemented.
