2024-12-17profcollect: Do not collect profiles when the battery is low Yi Kong
Collecting profiles can be a battery intensive task. Do not collect profiles when the battery is low. Test: presubmit Change-Id: I80fd370bc46b9dd3b9d20b3cdb81c8ab974f34a0
2024-12-09profcollect: Move periodic trace worker to the system server Yi Kong
We used to have the periodic background trace worker in the native side, and relied on Doze mode to pause the collection when the device is inactive. This is not very accurate. Instead, we move the worker to the system server where we know exactly if the device is interactive, and we can make sure we only trace when the device is executing workload useful for profiling. Test: manual Bug: 381005420 Change-Id: I3c063cb63cb8d54e3e175eeee3118d60ee79714c

Test: manual Bug: 370229109 Change-Id: Ib89dd05669225642b8a877828a85d5aae7e92791
2024-10-25profcollect: Disable tracing while ADB is connected Yi Kong
It is more likely that the device is being used for development work rather than day-to-day usage while ADB is connected. Stop tracing to remove bias introduced from development workload. Test: manual Bug: 370229109 Change-Id: Ie059e0adaa8ad25d0c342befe7d0e3c37cda8078
2024-10-02profcollect: introduce a cool down window between trace events Yi Kong

2024-07-24profcollect: Guard binder calls with null checks Yi Kong
In case of profcollectd dies, mIProfcollect will become null. Guard all calls to mIProfcollect with null checks to prevent NPE. Change-Id: I0908bd2413f77a44a00e2692bb027ba580ecbec6 Test: presubmit Bug: 354339294
2024-07-23profcollect: fix camera event delay logic Yi Kong
Follow up to https://r.android.com/3186246, we should *not* delay trace capture, instead of always adding the delay. Change-Id: I93d917963a1c73e4a28e945488b9b5cb1b16925b Test: presubmit Bug: 319394981
2024-07-22profcollect: Collect camera traces for a longer duration Yi Kong
Increase the duration so that we can get a more complete and accurate trace. Also since we trace for longer, we can always trace initialization behavior. Test: manual Bug: 319394981 Change-Id: Id6bc62d44da418c5e21bc7876971a4b64f59c25d
2024-07-08profcollect: Switch to process level tracing for camera open events Yi Kong
Process level tracing has a lower overhead and can produce more accurate profiles. Test: manual Bug: 319394981 Change-Id: Id27a3ec427af453b353a840f695bc20922734cc2
2024-07-07profcollect: Rename trace_once to trace_system Yi Kong

2024-07-04profcollect: collect intilization code behavior for camera open events Yi Kong
First several frames may have a different code behavior for camera code. Allocate a small percentage of traces to capture those behavior. Test: presubmit Change-Id: Icf343b23ee51dfb83798ecc4be9a3fb5a219412b

2024-06-06profcollect: Trace on camera open events Yi Kong
This allows us to collect traces for camera related libraries, like libg3a. For the initial experiment, we collect the traces one second after the camera opens. We can fine tune this or switch to other triggers once we have the benchmark numbers. Test: manual Bug: 319394981 Change-Id: Ia65694602af1054dd261f4e72c1c3f82056eb1e3

2022-04-25Reduce overhead of activity launch observer Riddle Hsu
The cost of writing ActivityRecordProto is heavy. Especially it executes in window manager's lock. Since the usage of proto was removed. The callback interface is simplified to only send id and name. Though currently there is no use case, it is more accurate to associate different launch sequence because the assumption "only one start at a time" is not true anymore since multi-window/area/display support.
