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.
