From 3bf7b07ece6e00747602938f68c1db8001b9925f Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Tue, 5 Mar 2013 21:48:26 -0800 Subject: [PATCH] perf/POWER7: Create a sysfs format entry for Power7 events Create a sysfs entry, '/sys/bus/event_source/devices/cpu/format/event' which describes the format of the POWER7 PMU events. This code is based on corresponding code in x86. Changelog[v4]: [Michael Ellerman, Paul Mckerras] The event format is different for other POWER cpus. So move the code to POWER7-specific, power7-pmu.c Also, the POWER7 format uses bits 0-19 not 0-20. Changelog[v2]: [Jiri Osla] Use PMU_FORMAT_ATTR rather than duplicating code.
