I am trying to use perf for profiling on a target Xavier. 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.What could be going wrong? Are there better ways to monitor those not-supported performances?
