Subject: [PATCH v5 5/5] perf mem: Support mem_lvl_num in c2c command
Date: Fri, 8 Apr 2022 19:53:44 +0000 [thread overview]
Message-ID: <20220408195344.32764-6-alisaidi@amazon.com> (raw)
In-Reply-To: <20220408195344.32764-1-alisaidi@amazon.com>
In addition to summarizing data encoded in mem_lvl also support data
encoded in mem_lvl_num.
Since other architectures don't seem to populate the mem_lvl_num field
here there shouldn't be a change in functionality.
