%description

This package contains the perf tool, which enables performance monitoring

of the Linux kernel.

%package -n libperf

Summary:        The perf library from kernel source

%description -n libperf

This package contains the kernel source perf library.

%package -n libperf-devel

Summary:        Development files for the perf library from kernel source

Requires:       libperf%{?_isa} = %{version}-%{release}

%description -n libperf-devel

This package includes libraries and header files needed for development

of applications which use perf library from kernel source.

%package -n python3-perf

Summary:        Python bindings for apps which will manipulate perf events

%description -n python3-perf

The python3-perf package contains a module that permits applications

written in the Python programming language to use the interface

to manipulate perf events.
