Subject: [PATCH 01/20] selftest/powerpc/pmu: Include mmap_buffer field as part of struct event
Date: Thu, 27 Jan 2022 12:49:53 +0530 [thread overview]
Message-ID: <20220127072012.662451-2-kjain@linux.ibm.com> (raw)
In-Reply-To: <20220127072012.662451-1-kjain@linux.ibm.com>
From: Athira Rajeev <atrajeev@linux.vnet.ibm.com>
To enable the capturing of samples as part of perf event,
add a new field "mmap_buffer" to "struct event". This
field is a place-holder for sample collection
