Subject: [PATCH 2/3] perf kvm stat report: Enable the target.system_wide flag
Date: Mon, 1 Sep 2014 17:44:54 +0400 [thread overview]
Message-ID: <1409579095-12963-3-git-send-email-yarygin@linux.vnet.ibm.com> (raw)
In-Reply-To: <1409579095-12963-1-git-send-email-yarygin@linux.vnet.ibm.com>
The 'perf kvm stat report' command can be used to analyze events either
for system wide or for specific pids. Let's enable
kvm->opts.target.system_wide flag when 'report' command is running for
system-wide analyzing. This helps to sync kvm->opts.target values in
'report' and 'live' commands.
