Libpfm4 helps convert from an event name, expressed as a string, to the event encoding. the encoding can then be used with specific os interfaces. libpfm4 also provides os-specific interfaces to directly setup os-specific data structures to be passed to the kernel. the current libpfm4, for instance, provides support for the perf_events interface which was introduced in linux v2.6.31.

this package provides the debug symbols of the shared library.
