Hi Steven,
This patch series extracts the trace_clock file for switching outputting format of timestamp. This patch series uses the options feature, so trace-cmd keeps backward compatibility.
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
v2: - Separate input/output patches (2/3 and 3/3) - Define TRACECMD_OPTION_TRACECLOCK for extracting trace_clock (2/3) - Check whether TRACECMD_OPTION_TRACECLOCK exists or not in trace.dat (3/3)
Thank you,
