Subject: [PATCH 8/9] perf: test 15 change period and frequency for s390x
Date: Wed, 9 Aug 2017 08:40:39 +0200 [thread overview]
Message-ID: <20170809064040.50899-8-tmricht@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170809064040.50899-1-tmricht@linux.vnet.ibm.com>
The perf record command can specify sampling period and frequency.
For s390x both values are too slow and needs to be increased.
On s390x there is a minimum value and when the specified
command line value is too low, the perf_event_system call
fails.
I have successfully tested these new values on Intel.
