2016-09-29	Simpleperf: don't expose EventSelection.	Yabin Cui
	And some tiny improvements. Bug: http://b/30974760 Test: run simpleperf_unit_test. Change-Id: Ie2d46c8ab9ee763d107527c9a54590f845569da4
2016-08-05	simpleperf: reduce Record construction overhead while recording.	Yabin Cui
	Avoid binary allocation and memory copy in ReadRecordsFromBuffer(), thus reduce Record construction overhead in EventSelectionSet::ReadMmapEventDataForFd(). Remove RecordCache used while recording. Replace it with RecordFileWriter::SortDataSection(). For unwinding while recording, use low watermark to make records almost sorted when dumped from the kernel. Bug: 30649868 Test: run simpleperf_unit_test. Change-Id: Ie5fb942046900a5960b3c990cf4177c026eaadfb
2016-06-15	simpleperf: add type modifier when reporting events.	Yabin Cui
	Before the change: $simpleperf record -e cpu-cycles:u sleep 1 $simpleperf report ... Event: cpu-cycles (type 0, config 0) ... After the change: $simpleperf report ... Event: cpu-cycles:u (type 0, config 0) ... Change-Id: I296c5476e03250e928ed0f579483d6866576d417
2016-04-05	simpleperf: support reporting more than one event type.	Yabin Cui
	When sampling kernel trace points, it is like to sample more than one even type. Like `simpleperf record -e kmem:mm_page_alloc,kmem:mm_page_free`. 1. change record command to dump event_id for all records. 2. change report command and record reader to support multiple event attrs. 3. hide record_cache inside EventSelectionSet. 4. add test to report multiple event types.

2015-05-15	Support tracepoint event types in simpleperf.	Yabin Cui
	Also support options in `simpleperf list`, add test about tracepoint event types. Bug: 19483574 Change-Id: I2d2c2f300fe5e2968696228899084410aa9f29a4
