This module provides several event counters from the perf
API provided by Linux (2.6+) - and they are not compatible with other systems. These counters are basically what the perf
command provides.
For some events, it is necessary to be root. If you try to use these counters with insufficient privileges, Bechamel_perf
will report you an permission error.
If you want to use Bechamel_perf
as a normal user, you should take a look on the documentation about perf_paranoid
.
