Subject: [PATCH 2/3] perf: Add macros to specify onchip L2/L3 accesses
Date: Sat,  4 Sep 2021 12:19:31 +0530	[thread overview]
Message-ID: <20210904064932.307610-2-kjain@linux.ibm.com> (raw)
In-Reply-To: <20210904064932.307610-1-kjain@linux.ibm.com>

Add couple of new macros to represent onchip L2 and onchip L3 accesses.
Patch also adds the decoding strings in the mem_lvlnum data structure.
