select BR2_PACKAGE_LINUX_TOOLS
help
perf (sometimes "Perf Events" or perf tools, originally
"Performance Counters for Linux") - is a performance
analyzing tool in Linux, available from kernel version
2.6.31. User-space controlling utility, called 'perf' has
git-like interface with subcommands. It is capable of
statistical profiling of entire system (both kernel and user
code), single CPU or severals threads.
This will build and install the userspace 'perf'
command.
Your kernel must have CONFIG_PERF_EVENTS enabled to use perf
profiling. Buildroot automatically enables this in the kernel
configuration.

Build and install (to /usr/lib/kselftests) kernel selftests.
Use of this option implies you know the process of using and
compiling the kernel selftests. The Makefile to build and
install these is very noisy and may appear to cause your
build to fail for strange reasons.
This is very much a use at your risk option and may not work
for every setup or every architecture.
