performance counter for linux question.

[sebastien cabaniols]

Hello list,

I am interested by monitoring instructions versus cycles with a Nehalem box 
using 2.6.31 with PCL.

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 ?
