In the latter case, the library is able to prepare +the OS-specific data structures needed by the kernel to setup the event. + +libpfm4 provides support for the @code{perf_events} interface, which was +introduced in Linux 2.6.31.") + (home-page "http://perfmon2.sourceforge.net/") + (license license:expat))) |
