17 config BR2_LINUX_KERNEL_TOOL_PERF
20 perf (sometimes "Perf Events" or perf tools, originally
21 "Performance Counters for Linux") - is a performance
22 analyzing tool in Linux, available from kernel version
23 2.6.31. User-space controlling utility, called 'perf' has
24 git-like interface with subcommands. It is capable of
25 statistical profiling of entire system (both kernel and user
26 code), single CPU or severals threads.
28 This will build and install the userspace 'perf'
29 command. It is up to the user to ensure that the kernel
30 configuration has all the suitable options enabled to allow a
31 proper operation of 'perf'.

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