Hello everyone

I need some hints on how to proceed further. I am sorry if this is not
the right place to ask this type of question.

I need to collect some performance counters using perf tool. But I am
always getting the following output.

Kernel: 2.6.35-7

Performance counter stats for 'ls':

          2.624511  task-clock-msecs         #      0.677 CPUs
                 0  context-switches         #      0.000 M/sec
                 0  CPU-migrations           #      0.000 M/sec
                62  page-faults              #      0.024 M/sec
     <not counted>  cycles
     <not counted>  instructions
     <not counted>  branches
     <not counted>  branch-misses
     <not counted>  cache-references
     <not counted>  cache-misses

       0.003875716  seconds time elapsed

I have recompiled the kernel to enable the support for events and
counters but to no avail. Any help or tips would be beneficial.

Regards

Abdul
