%description
This package provides a library that can be used to encode events into the
format required by the operating systems performance monitoring subsystem.

%package -n %{vname}
Summary:        Runtime library to encode performance events for use by perf tool
Group:          System/Libraries

%description -n %{vname}
This package provides a library that can be used to encode events into the
format required by the operating systems performance monitoring subsystem.
The library does not make any performance monitoring system calls, it simply
provides a method to convert an event name, expressed as a string, to an event
encoding. The user of the library may use this event encoding in a subsequent
system call.

The current libpfm4 provides support for the perf_events interface which was
introduced in Linux v2.6.31.
