| help |
| perf (sometimes "Perf Events" or perf tools, originally |
| "Performance Counters for Linux") - is a performance |
| analyzing tool in Linux, available from kernel version |
| 2.6.31. 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. It is up to the user to ensure that the kernel |
| configuration has all the suitable options enabled to allow a |
| proper operation of 'perf'. |

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