Subject: [RFC 2/3] perf/tools: Pass pmu_event structure as a parameter for arch_get_runtimeparam
Date: Thu, 25 Jun 2020 17:17:17 +0530	[thread overview]
Message-ID: <20200625114718.229911-3-kjain@linux.ibm.com> (raw)
In-Reply-To: <20200625114718.229911-1-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.
