Subject: [PATCH v8 4/5] perf/tools: Pass pmu_event structure as a parameter for arch_get_runtimeparam
Date: Sun,  6 Sep 2020 16:50:03 +0530
Message-ID: <20200906112004.49574-5-kjain@linux.ibm.com> (raw)
In-Reply-To: <20200906112004.49574-1-kjain@linux.ibm.com>

This patch adds passing of  pmu_event as a parameter in function
'arch_get_runtimeparam' which can be used to get details like
if the event is percore/perchip.
