I had to do a 'make -C

detected precise level.
Following record:
$ perf record -e cycles:P ...
will detect maximum precise level for 'cycles' event
and use it.
Does the end result (which precise level is used) get saved
The 'P' will cause the event to get maximum possible
detected precise level.
Following record:
$ perf record -e cycles:P ...
will detect maximum precise level for 'cycles' event
and use it.
