Instrumentation Support[]


  • Option: KPROBES
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Kprobes (EXPERIMENTAL)
      Kprobes allows you to trap at almost any kernel address and execute a callback function. register_kprobe() establishes a probepoint and specifies the callback. Kprobes is useful for kernel debugging, non-intrusive instrumentation and testing. If in doubt, say "N".
