Is the command simply terminating without any output? I cannot reproduce it. In my machines it works:
$ ./perf report --header-only -I # ======== # captured on: Tue Jun 13 23:49:13 2017 # hostname : lphh20 # os release : 4.3.5-smp-801.43.0.0 # perf version : 4.12.rc4.gf2978e # arch : x86_64 # nrcpus online : 72 # nrcpus avail : 72 # cpudesc : Intel(R) Xeon(R) CPU E5-2696 v3 @ 2.30GHz # cpuid : GenuineIntel,6,63,2 # total memory : 264134144 kB # cmdline : /root/perf record ls # event : name = cycles:pp, , size = 112, { sample_period, sample_freq } = 4000, sample_type = IP|TID|TIME|PERIOD, disa # sibling cores : 0-17,36-53 # sibling cores : 18-35,54-71 [SNIP]
Is your perf.data from the same version?
