Linux Tech Center: Kernel Probes
Anonymous Reader writes "With each probe, a corresponding probe event handler address is specified. Probe event handlers run as extensions to the system breakpoint interrupt handler and are expected to have little or no dependence on system facilities. Because of this design point, probes are able to be implanted in the most hostile environments -- interrupt-time, task-time, disabled, inter-context switch and SMP-enabled code paths -- without adversely skewing system performance."
