1menuconfig INSTRUMENTATION
2 bool "Instrumentation Support"
3 default y
4 ---help---
5 Say Y here to get to see options related to performance measurement,
6 system-wide debugging, and testing. This option alone does not add any
7 kernel code.
8
9 If you say N, all options in this submenu will be skipped and
10 disabled. If you're trying to debug the kernel itself, go see the
11 Kernel Hacking menu.

15config PROFILING
16 bool "Profiling support (EXPERIMENTAL)"
17 help
18 Say Y here to enable the extended profiling support mechanisms used
19 by profilers such as OProfile.

22 tristate "OProfile system profiling (EXPERIMENTAL)"
23 depends on PROFILING && !UML
24 depends on ARCH_SUPPORTS_OPROFILE || ALPHA || ARM || BLACKFIN || IA64 || M32R || PARISC || PPC || S390 || SUPERH || SPARC
25 help
26 OProfile is a profiling system capable of profiling the
27 whole system, include the kernel, kernel modules, libraries,
28 and applications.
29
30 If unsure, say N.

32config KPROBES
33 bool "Kprobes"
34 depends on KALLSYMS && MODULES && !UML
35 depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
36 help
37 Kprobes allows you to trap at almost any kernel address and
38 execute a callback function. register_kprobe() establishes
39 a probepoint and specifies the callback. Kprobes is useful
40 for kernel debugging, non-intrusive instrumentation and testing.
41 If in doubt, say "N".

43config MARKERS
44 bool "Activate markers"
45 help
46 Place an empty function call at each marker site. Can be
47 dynamically changed for a probe function.
