Anton Blanchard 6795b85c6a powerpc: tracing: Add powerpc tracepoints for timer entry and exit ... We can monitor the effectiveness of our power management of both the kernel and hypervisor by probing the timer interrupt. For example, on this box we see 10.37s timer interrupts on an idle core: <idle>-0 [010] 3900.671297: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3900.671302: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3911.042963: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3911.042968: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3921.414630: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3921.414635: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 Since we have a 207MHz decrementer it will go negative and fire every 10.37s even if Linux is completely idle.
