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. It is up to the user to ensure that the kernel configuration has all the suitable options enabled to allow a proper operation of 'perf'. https://perf.wiki.kernel.org/ config BR2_LINUX_KERNEL_TOOL_SELFTESTS bool"selftests" depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS # bash depends on BR2_USE_MMU # bash select BR2_PACKAGE_BASH # runtime select BR2_PACKAGE_POPT select BR2_PACKAGE_LIBCAP_NG help Build and install (to /usr/lib/kselftests) kernel selftests.

The Makefile to build and install these is very noisy and may appear to cause your build to fail for strange reasons.
