             Bug #: 13820
           Summary: timer.profile(NNN) variant using perf probes
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


It would be nice to have some syntactic sugar implemented in the
translator to present a profiling/backtrace-capable probe point
at arbitrary frequencies, and implement them in terms of 
perf.hw.cpu_cycles (unscaled variant if possible), related to
the cpu core speed and the script-requested Hz rate.
