bus: arm-ccn: Fix PMU handling of MN
The "Miscellaneous Node" fell through cracks of node initialisation, as its ID is shared with HN-I. This patch treats MN as a special case (which it is), adding separate validation check for it and pre-defining the node ID in relevant events descriptions. That way one can simply run: # perf stat -a -e ccn/mn_ecbarrier/ <workload> Additionally, direction in the MN pseudo-events XP watchpoint definitions is corrected to be "TX" (1) as they are defined from the crosspoint point of view (thus barriers are transmitted from XP to MN). Cc: [email protected] # 3.17+ Signed-off-by: Pawel Moll <[email protected]>
