2018-03-07simpleperf: Fix cached map in OfflineUnwinder.Yabin Cui
In system wide profiling, sometimes a sample record goes before all mmap records of a process. Then thread.maps->version = 0 and cached_map.map isn't created. This is caught by simpleperf_unit_test. Bug: none Test: run simpleperf_unit_test. Change-Id: I99254396d0fb22531f735ff3193b8d3b1f9641dd

When calculating cpu frequency and other frequencies, use time running on cpu instead of total passed time. This is to be consistent with linux-tools-perf.

2018-02-05simpleperf: add debug-unwind cmd.Yabin Cui
Currently, we use --log debug option in record cmd to debug offline unwinding. However, it has below disadvantages: 1. It adds extra complexity in record cmd. 2. It doesn't keep reg/stack data of samples. 3. It isn't convenient to reproduce samples in problem. Because each time recording gets different samples. 4. It isn't very suitable for performance test of unwinding, for the same reason as item 3. So instead, this CL adds debug-unwind cmd focusing on debugging and testing offline unwinding. It solves problems mentioned above. Also change unwinding_result_reporter.py to make it work with perf.data generated by debug-unwind cmd. Bug: http://b/72556486 Test: run simpleperf_unit_test. Test: run unwinding_result_reporter.py manually. Change-Id: I11cdf1eba993f48d61ef9891ad1be54d29679fdb

2018-01-31simpleperf: Switch to use post-unwind by default in record cmd.Yabin Cui
When recording google.sample.tunnel app for 30s: It took 3s to unwind samples and write unwound samples to file. It took 0.3s to write samples containing stack/reg data to file. The result shows recording with post unwinding consumes much less time than unwinding samples immediately. This means we can record with higher freq and get smaller lose rate when using post unwinding. So make below changes: 1. Make post unwinding by default. 2. Replace --post-unwind with --no-post-unwind option. 3. Make --trace-offcpu and callchain joiner work with post unwinding. 4. Remove special operations in --log debug mode. Those will be supported in a new command. Bug: http://b/72556486 Test: run simpleperf_unit_test. Test: run python test.py. Change-Id: I9a5a5defda9d040985e674c43db19ee68e7aa305
