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