Subject: [PATCH v2 1/3] perf kvm: Introduce evsel as argument to perf_event__preprocess_sample
Date: Fri, 22 Jan 2016 11:28:10 +0530	[thread overview]
Message-ID: <1453442292-7790-2-git-send-email-ravi.bangoria@linux.vnet.ibm.com> (raw)
In-Reply-To: <1453442292-7790-1-git-send-email-ravi.bangoria@linux.vnet.ibm.com>

This patch changes prototype of perf_event__preprocess_sample() with
additional argument evsel added at last.

This change is required because perf_event__preprocess_sample()
function will use evsel to determine cpumode of samples for powerpc
architecture.
