[RFCv2 0/10] perf, tool: Allow to use hw events in PMU syntax

From: Jiri Olsa
Date: Tue Jul 03 2012 - 18:01:37 EST

here's the change to make following syntax available:
perf stat -e cpu/event=instructions/u ls

this is identical to:
perf stat -e instructions:u ls

v2 changes:
- making the hw events translations available under the 'events',
the userspace trnaslation is then done by existing term aliasing
code with some little tweeks ;)
- patches 1-3 are independent fixies

Attached patches:
01/10 perf, tool: Add empty rule for new line in event syntax parsing
02/10 perf, tool: Fix pmu object initialization
03/10 perf, tool: Properly free format data
04/10 perf, x86: Making hardware events translations available in sysfs
05/10 perf, tool: Split out PE_VALUE_SYM parsing token to SW and HW tokens
06/10 perf, tool: Split event symbols arrays to hw and sw parts
07/10 perf, tool: Add support to specify hw event as pmu event term
08/10 perf, tool: Add sysfs read file interface
09/10 perf, test: Use ARRAY_SIZE in parse events tests
10/10 perf, test: Add automated tests for pmu sysfs translated events
