    Subject[PATCH v6 6/7] powerpc/perf/hv-gpci: add the remaining gpci requests
    Date
    From: Cody P Schafer <cody@linux.vnet.ibm.com>

    Add the remaining gpci requests that contain counters suitable for use
    by perf. Omit those that don't contain any counters (but note their
    ommision).

    Changelog[v6]

    [Jiri Olsa, Sukadev Bhattiprolu] Replace 'starting_index' with what
    it really means for the event. Eg if starting_index refers to a
    partition_id for an event, allow user to specify a value for
    partition_id rather than 'starting_index'. Also use a =? to indicate
    required parameters: eg partition_id=?
