From 5f537a26590e696466aae7f41e6b77e92c8486d1 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 15 Mar 2012 20:09:18 +0100 Subject: perf tools: Add support to specify pmu style event Added new event rule to the event definition grammar: event_def: event_pmu | ... event_pmu: PE_NAME '/' event_config '/' Using this rule, event could be now specified like: cpu/config=1,config1=2,config2=3/u where pmu name 'cpu' is looked up via following path: ${sysfs_mount}/bus/event_source/devices/${pmu} and config options are bound to the pmu's format definiton: ${sysfs_mount}/bus/event_source/devices/${pmu}/format The hardcoded config options still stays and have precedence over any format field defined with same name.
