These tools use new gpio ABI which will deprecate sysfs gpio interface in the future.

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. https://perf.wiki.kernel.org/ if BR2_PACKAGE_LINUX_TOOLS_PERF config BR2_PACKAGE_LINUX_TOOLS_PERF_TUI bool "enable perf TUI" depends on BR2_USE_MMU # slang select BR2_PACKAGE_SLANG help Enable the TUI interface for perf which requires a TTY and enables zooming into DSOs and threads as well as other features. endif 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 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) help Build and install (to /usr/lib/kselftests) kernel selftests.
