I am trying to use perf for profiling CPU performance on the target (Pegasus). However, I am receiving the following output:
Performance counter stats for 'CPU(s) 1':
3002.616160 cpu-clock (msec) # 1.000 CPUs utilized
253 context-switches # 0.084 K/sec
33 cpu-migrations # 0.011 K/sec
0 page-faults # 0.000 K/sec
<not supported> cycles
<not supported> instructions
<not supported> branches
<not supported> branch-misses
3.002808256 seconds time elapsed
Many of the interesting values seem not to be supported. Did I miss something? Are there better ways to monitor those not-supported performances?
Thanks!
