| |
Hi,
We can monitor timer's lifecycle and behaviors by these tracepoint.
Following tracepoints are introduced as ingo's suggestion in http://marc.info/?l=linux-kernel&m=123791899529128&w=2
for timer: trace_timer_init() trace_timer_start() trace_timer_expire() trace_timer_cancel()
for hrtimer: trace_hrtimer_init() trace_hrtimer_start() trace_hrtimer_expire() trace_hrtimer_cancel()
for itimer: itimer_state itimer_expire()
Changlog from latest patchset: 1: ours patches are base on Anton Blanchard's patch which can been found at: http://marc.info/?l=linux-kernel&m=124331396919301&w=2 but this patch is can't apply on Ingo's tip tree, so we rebase this patch against latest tip tree
2: fix those patches address Thomas's comment
