25 select BR2_PACKAGE_LINUX_TOOLS
27 gpio is a collection of tools to get information about,
28 control and monitor gpios present on system.
30 These tools use new gpio ABI which will deprecate sysfs gpio
31 interface in the future.
33 These tools are available only from kernel version 4.8.

37 select BR2_PACKAGE_LINUX_TOOLS
39 iio is a collection of tools to get information about,

42 These tools are available only from kernel version 4.7.
44 config BR2_PACKAGE_LINUX_TOOLS_PERF
46 select BR2_PACKAGE_LINUX_TOOLS
48 perf (sometimes "Perf Events" or perf tools, originally
49 "Performance Counters for Linux") - is a performance
50 analyzing tool in Linux, available from kernel version
51 2.6.31. User-space controlling utility, called 'perf' has
52 git-like interface with subcommands. It is capable of
53 statistical profiling of entire system (both kernel and user
54 code), single CPU or severals threads.
56 This will build and install the userspace 'perf'
57 command. It is up to the user to ensure that the kernel
58 configuration has all the suitable options enabled to allow a
59 proper operation of 'perf'.

72 Build and install (to /usr/lib/kselftests) kernel selftests.
74 Use of this option implies you know the process of using and
75 compiling the kernel selftests. The Makefile to build and
76 install these is very noisy and may appear to cause your
77 build to fail for strange reasons.
79 This is very much a use at your risk option and may not work
80 for every setup or every architecture.
