Line 3:
PAPI provides predefined high level hardware events summarized from popular processors and direct access to low level native events of one particular processor. Counter [[multiplexing]] and [[arithmetic_overflow|overflow]] handling are also supported.
[[Operating system]] support for accessing hardware counters is needed to use PAPI.
For example, before around 2010 a [[Linux (kernel)|Linux/x86 kernel]] Since Linux version 2.6.32, and PAPI 2010 releases, PAPI can leverage the existing perf subsystem in Linux, and thus does not need any out of tree driver to be functional anymore.
Supported Operating Systems and requirements are listed in the official repository's documentation [https://bitbucket.org/icl/papi/raw/0fdac4fc7f95f0ac8039e431419a5133088911af/INSTALL.txt INSTALL.txt].
