Arnaldo Carvalho de Melo 26252ea675 perf evlist: Show event attribute details
There was no easy way to see the frequency used, and with the change of
default, we better provide one.

[root@sandy linux]# perf evlist -F
cycles: sample_freq=4000
[root@sandy linux]# perf evlist -v
cycles: sample_freq=4000, size: 80, sample_type: 391, read_format: 7, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, sample_id_all: 1, exclude_guest: 1
