Instrumentation SupportEdit


  • 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".






Use the generic interrupt handling code in kernel/irq/:


  • Option: GENERIC_HARDIRQS
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • default y


  • Option: GENERIC_IRQ_PROBE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • default y


  • Option: GENERIC_PENDING_IRQ
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • depends on GENERIC_HARDIRQS && SMP
    • default y


  • Option: X86_SMP
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • depends on SMP && !X86_VOYAGER
    • default y


  • Option: X86_HT
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • depends on SMP && !(X86_VISWS || X86_VOYAGER)
    • default y


  • Option: X86_BIOS_REBOOT
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • depends on !(X86_VISWS || X86_VOYAGER)
    • default y


  • Option: X86_TRAMPOLINE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off)
    • depends on X86_SMP || (X86_VOYAGER && SMP)
    • default y
