Subject: [PATCH 0/2] trace-cmd: Support a raw format for outputting timestamp

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,
