2016-08-30simpleperf: add python report interface on linux.Yabin Cui
1. Build libsimpleperf_report.so on host, which exports functions to access samples. 2. Add simpleperf_report_lib.py to wrap libsimpleperf_report.so. 3. Write report_sample.py to test simpleperf_report_lib.py. The output format of report_sample.py matches the need of building FlameGraph. Bug: http://b/31069528 Test: run report_sample.py on perf.data. Test: run simpleperf_unit_test. Change-Id: I4949f8ea506f12101a9c4fb4c896957c96676853

2016-08-26simpleperf: support hotplug events in record cmd.Yabin Cui
1. When a cpu is down, read records from event files on that cpu, then close those event files. 2. When a cpu is up, open event files on that cpu, and create mapped buffer for those event files to dump records. 3. Instead of creating a mapped buffer for each event type on each cpu, we can just create a mapped buffer for all event types on each cpu. 4. When new event files are created, store a EventIdRecord record in perf.data to notify record_file_reader.cpp. Bug: http://b/29245608 Test: run simpleperf record cmd and make cpu offline and online. Test: run simpleperf_unit_test. Change-Id: Ib97a24b6292fa143e9b35cb105bdddf1e826d60a

2016-08-25simpleperf: support hotplug events in stat cmd.Yabin Cui
1. When a cpu is down, read counters from event files on that cpu, then close those events files. 2. When a cpu is up, open event files on that cpu. 3. Remove check of time_running != 0 in cmd_stat.cpp, because 1) We no longer need the check as we no longer open event file for each cpu for non system wide profiling. 2) The kernel has a bug that can make time_running == 0 if a cpu is down while profiling. But the counter value is still valid, and shouldn't be ignored. Bug: http://b/29245608 Test: run simpleperf and make cpu offline and online. Change-Id: I3e7bec139c5f50bea1311c95bb154a5b290a72ea
