+From 821c1c36ba8883a8709bbbcdf4ebc716e69da991 Mon Sep 17 00:00:00 2001

+Date: Fri, 3 Dec 2021 11:45:00 +0000
+Subject: [PATCH 25/40] perf/arm-cmn: Support new IP features
+
+The second generation of CMN IPs add new node types and significantly
+expand the configuration space with options for extra device ports on
+edge XPs, either plumbed into the regular DTM or with extra dedicated
+DTMs to monitor them, plus larger (and smaller) mesh sizes. Add basic
+support for pulling this new information out of the hardware, piping
+it around as necessary, and handling (most of) the new choices.
