From 8f06c51fac1ca4104b8b64872f310e28186aea42 Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Thu, 2 Apr 2015 14:01:06 +0100 Subject: bus: arm-ccn: Provide required event arguments Since 688d4dfcdd624192cbf03c08402e444d1d11f294 "perf tools: Support parsing parameterized events" the perf userspace tools understands "argument=?" syntax in the events file, making sure that required arguments are provided by the user and not defaulting to 0, causing confusion. This patch adds the required arguments lists for CCN events.
