2017-07-14simpleperf: change the way running cts tests.Yabin Cui
Before this CL, CtsSimpleperfTestCases copies itself to the app's directory, then run it using run-as. With this CL, CtsSimpleperfTestCases keeps itself in /data/local/tmp, but forces stat/record cmd to run with --app option. This gives more freedom to tests: 1. They can stay in shell's context with --in-app option. 2. The stat/record cmds are started in the shell's context, so they can collect information no available in app's context (like data in /sys/kernel/debug/tracing/events). This is a preparation to add tests for recording tracepoint events. It also matches the way we want users to use simpleperf (with --app option). Bug: http://b/29520177 Test: run CtsSimpleperfTestCases. Change-Id: I1709adfb1ff7169df87560226c197e473fdf8516
2017-02-10simpleperf: build libsimpleperf_inplace_sampler library.Yabin Cui
libsimpleperf_inplace_sampler.so is a library linked with user's app. It opens a unix socket server and waits for simpleperf's profiling request. This patch doesn't contain code generating real samples, instead it uses a fake sample for testing. Add runtest for 32bit. Increase runtest duration to 2 seconds and adjust some args in runtest.conf to make test result stable. Fix one tiny error in cmd_report.cpp to report correctly in `report --sort comm,symbol`. Bug: http://b/30974760 Test: run simpleperf_unit_test. Test: run runtest.py. Change-Id: I58163fe47f62e6ba7dd684b33a2ce302feb880f5
2016-12-13simpleperf: check monitored targets regularly.Yabin Cui
When monitoring some threads/processes not forked by simpleperf, check if these threads/processes exist regularly. So we can stop profiling once all threads/processes exit. Also handle SIGHUP signal, so we can finish profiling properly when `adb shell simpleperf record xxx` is killed by Ctrl-C. Add corresponding tests. Bug: http://b/33558210 Test: run simpleperf_unit_test. Change-Id: Ieae4d00d099dc1c7a0c51b0610dff43981bb642e
2016-11-29simpleperf: fix tests for dwarf callgraph unwinding.Yabin Cui
32-bit simpleperf can't unwind a 64-bit `sleep` process in aarch64 environment. It makes following error in tests: simpleperf is built in arch arm, and can't do stack unwinding for arch arm64 So make the workload be able to start a process running callback function. By profiling that process, we can guarantee that 32-bit simpleperf is profiling a 32-bit process. Also fix a flaky test IOEventLoop.signal. Build 32-bit simpleperf_unit_test on 64-bit devices. Bug: http://b/33167911 Test: run simpleperf_unit_test. Change-Id: I82741dc5d90c73c1890f834d8e2a9188421a3828

If there is no need to record samples, u/k modifiers used in event cpu-clock and task-clock are ignored by the kernel. Bug: http://b/29574526 Change-Id: Id45568448888965a3bfa382c4420e395a741f77a Test: simpleperf_unit_test.

2016-08-05simpleperf: allow --duration option when executing child command.Yabin Cui
Previously --duration option can't be used while executing child command, mainly because we use `sleep XX` child command to implement --duration option. By using libevent, the limit doesn't exist.

2016-07-06Simpleperf: add auto generated summaries in stat command.Yabin Cui
When there are summaries monitoring one event type in user space and kernel space at the same time period, we can automatically generate a summary combining the results generated in user space and kernel space. This can help to decrease the number of needed hardware counters. Also adjust scale check when deciding whether an event is monitored all the time.

2016-06-27Simpleperf: fix flaky tests.nougat-devYabin Cui
Simpleperf stat/record command may need 1 second to set security.perf_harden property. So the monitored child threads should run longer than 1 second. Bug: 29763505 Change-Id: I9bf6dcba03f3fc5c91130f38a08ce0062e104103
2016-06-17simpleperf: support event group.Yabin Cui
Kernel supports monitoring several events as a group, so they are scheduled on and out at the same time. Add --group option to stat command and record command. Adjust the method to calculate miss rate in stat command: limit the matched events in the same group or with scale == 1.0. Bug: 29213742 Change-Id: I899aba207f1e3357307541e81f97526f5a2913c3
2016-04-01simpleperf: loosen unwinding arch check for system wide collection.Yabin Cui
When doing system wide collection, it is possible that there are 32-bit compat processes running on 64-bit devices. It is not proper to abort in this situation. So loosen the check to allow it. Also add corresponding test. Bug: 27927427 Change-Id: I5c9253eb6e474497e4f37e234e0e523e141fab20
