2020-01-14simpleperf: prepare for selinux change.Yabin Cui
To work with controlling perf_events via selinux: 1. Check security.perf_harden property at the entry of simpleperf. 2. Record tracepoint raw data only when running as root. Bug: 139860059 Test: run simpleperf_unit_test. Change-Id: I40082de0010949e54fb707f385220157a71f266b
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
2017-05-03simpleperf: add META_INFO feature section in perf.data.Yabin Cui
META_INFO section can be used to pass some small information in perf.data. Add simpleperf_version in META_INFO section for debugging. Bug: http://b/37960318 Test: run simpleperf_unit_test. Change-Id: If17a147bbc77b5af063fbf77e02ca81430afb8a5
2017-02-15simpleperf: build cts test running in app context.Yabin Cui
When built for cts test, the test binary uses run-as to move itself to the data directory of debuggable app 'com.android.simpleperf', and run the tests in app context using run-as. Bug: http://b/18790309 Test: run cts-tradefed, 'run everything -m CtsSimpleperfTestCase'. Change-Id: I523470bb8062cb944b44dc6f264a8b1c14221b62

2015-06-04Simpleperf: refactor command system.Yabin Cui
