Subject: [PATCH v4 4/5] perf/tools: Pass pmu_event structure as a parameter for arch_get_runtimeparam
Date: Mon, 20 Jul 2020 12:31:26 +0530 [thread overview]
Message-ID: <20200720070127.109234-5-kjain@linux.ibm.com> (raw)
In-Reply-To: <20200720070127.109234-1-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.
