Hi Steven,
This patch series extracts the trace_clock file for switching outputting format
of timestamp because in tsc or counter modes, trace-cmd should output timestamp
not in the sec.usec format but in the raw format.
For example, we will show results in trace-cmd report mode as follows by
applying this patch series:
<for local or global mode>
bash-9022 [000] 34984.109846: sched_wakeup:
comm=migration/3 pid=23 prio=0 success=1 target_cpu=003
<idle>-0 [002] 34984.109847: cpu_idle:
state=4294967295 cpu_id=2
bash-9022 [000] 34984.109848: sched_switch: prev_comm=bash
prev_pid=9022 prev_prio=120 prev_state=R ==> next_comm=migration/0 next_pid=8
next_prio=0
<idle>-0 [002] 34984.109849: sched_switch:
prev_comm=swapper/2 prev_pid=0 prev_prio=120 prev_state=R ==>
next_comm=migration/2 next_pid=18 next_prio=0
<for tsc or counter mode>
bash-9022 [000] 34984109846: sched_wakeup:
comm=migration/3 pid=23 prio=0 success=1 target_cpu=003
<idle>-0 [002] 34984109847: cpu_idle:
state=4294967295 cpu_id=2
bash-9022 [000] 34984109848: sched_switch: prev_comm=bash
prev_pid=9022 prev_prio=120 prev_state=R ==> next_comm=migration/0 next_pid=8
next_prio=0
<idle>-0 [002] 34984109849: sched_switch:
prev_comm=swapper/2 prev_pid=0 prev_prio=120 prev_state=R ==>
next_comm=migration/2 next_pid=18 next_prio=0
Would you apply this patch series for trace-cmd?
Thank you,
