Subject: [RFC] increase perf kvm stat accuracy
Date: Thu, 31 Jul 2014 13:13:50 +0200 [thread overview]
Message-ID: <1406805231-10675-1-git-send-email-borntraeger@de.ibm.com> (raw)
On my s390 kvm system most of the kvm exits are in the range
of 0 or 1 microseconds. Can we increase the accuracy by 2
additional digits?
Opinions?
