Subject: [PATCH 03/17] perf script: Allow showing the --switch-on event
Date: Fri, 16 Aug 2019 17:16:39 -0300 [thread overview]
Message-ID: <20190816201653.19332-4-acme@kernel.org> (raw)
In-Reply-To: <20190816201653.19332-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
One may want to see the --switch-on event as well, allow for that, using
the previous cset example:
# perf script --switch-on syscalls:sys_enter_nanosleep --show-on-off
sleep 13638 [001] 108237.582286: syscalls:sys_enter_nanosleep: rqtp: 0x7fff1948ac40, rmtp: 0x00000000
sleep 13638 [001] 108237.582289: sched:sched_stat_runtime: comm=sleep pid=13638 runtime=578104 [ns] vruntime=202889459556 [ns]
sleep 13638 [001] 108237.582291: sched:sched_switch: sleep:13638 [120] S ==> swapper/1:0 [120]
swapper 0 [001] 108238.582428: sched:sched_waking: comm=sleep pid=13638 prio=120 target_cpu=001
swapper 0 [001] 108238.582458: sched:sched_wakeup: sleep:13638 [120] success=1 CPU:001

sleep 13638 [001] 108238.582782: sched:sched_process_exit: comm=sleep pid=13638 prio=120
#
