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.

Note: rtla in kernels before 5.19 had additional dependencies, not available in Buildroot, so only rtla in kernels 5.19 onwards is actually supported in Buildroot. comment "rtla needs a toolchain w/ threads, dynamic library" depends on !BR2_TOOLCHAIN_HAS_THREADS || BR2_STATIC_LIBS config BR2_PACKAGE_LINUX_TOOLS_SELFTESTS bool"selftests" depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS # bash depends on BR2_USE_MMU # bash depends on !BR2_STATIC_LIBS depends on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_14 # util-linux schedutils select BR2_PACKAGE_LINUX_TOOLS select BR2_PACKAGE_BASH # runtime select BR2_PACKAGE_NCURSES select BR2_PACKAGE_NCURSES_TARGET_PROGS # runtime (tput) select BR2_PACKAGE_KMOD select BR2_PACKAGE_KMOD_TOOLS # runtime (modprobe -n) select BR2_PACKAGE_POPT select BR2_PACKAGE_LIBCAP_NG select BR2_PACKAGE_UTIL_LINUX select BR2_PACKAGE_UTIL_LINUX_SCHEDUTILS # runtime (taskset) select BR2_PACKAGE_OPENSSL if BR2_x86_64 help Build and install (to /usr/lib/kselftests) kernel selftests.
