Subject: [PATCH 0/7] perf tools: Add switch-output size and time threshold options
Date: Tue, 3 Jan 2017 09:19:53 +0100 [thread overview]
Message-ID: <1483431600-19887-1-git-send-email-jolsa@kernel.org> (raw)
hi,
adding a way to configure switch data output
for size and time, like:
$ sudo perf record -e 'sched:*' --switch-output=10M -avg
callchain: type FP
switch-output with 10M size threshold
mmap size 528384B
[ perf record: dump data: Woken up 37 times ]
[ perf record: Dump perf.data.2017010309135512 ]
[ perf record: dump data: Woken up 39 times ]
[ perf record: Dump perf.data.2017010309135771 ]
[ perf record: dump data: Woken up 38 times ]
[ perf record: Dump perf.data.2017010309140005 ]
^C[ perf record: Woken up 16 times to write data ]
[ perf record: Dump perf.data.2017010309140111 ]
[ perf record: Captured and wrote 4.748 MB perf.data.<timestamp> ]
...
the default for switch-output option stays
and does the SIGUSR2 output switch

thanks,
