Subject: [PATCH v2 0/4] perf python: Add missing infra pieces for counting perf events

Add the missing infra code in the perf python bindings for measuring and
reading the counter values for the given perf event. Demonstrate the
usage of this with counting.py - a python version of counting.c

v1 -> v2:
1. Use the existing iteration support for evlist
2. Drop the use of next method
3. Use existing helper functions for python example

Gautam Menghani (4):
  perf python: Add support for perf_counts_values to return counter data
  perf python: Add evsel read method
  perf python: Add evlist close support
  perf python: Add counting.py as example for counting perf events
