Is there a way with perf report to display both counters ? I used perf record -e cycles -e instructions -a for the recording session. perf report -n seems to be doing what I need but for only one counter. Is this a limitation of perf report ? Is this an architectural limitation of PCL ? Is there more documentation than what is in the perf directory in the 2.6.31 tarball ? -- Sébastien Cabaniols SCI Presales EMEA HP current timezone = UTC+2 (localtime is approx. 14:20)
