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

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