## Window manager performance tests
|
|
|
|
### Precondition
|
|
To reduce the variance of the test, if `perf-setup.sh` (platform_testing/scripts/perf-setup)
|
|
is available, it is better to use the following instructions to lock CPU and GPU frequencies.
|
|
```
|
|
m perf-setup
|
|
PERF_SETUP_PATH=/data/local/tmp/perf-setup.sh
|
|
adb push $OUT/$PERF_SETUP_PATH $PERF_SETUP_PATH
|
|
adb shell chmod +x $PERF_SETUP_PATH
|
|
adb shell $PERF_SETUP_PATH
|
|
```
|
|
|
|
### Example to run
|
|
Use `atest`
|
|
```
|
|
atest WmPerfTests:RelayoutPerfTest -- \
|
|
--module-arg WmPerfTests:instrumentation-arg:kill-bg:=true
|
|
```
|
|
Use `am instrument`
|
|
```
|
|
adb shell am instrument -w -r -e class android.wm.RelayoutPerfTest \
|
|
-e listener android.wm.WmPerfRunListener \
|
|
-e kill-bg true \
|
|
com.android.perftests.wm/androidx.test.runner.AndroidJUnitRunner
|
|
```
|
|
* `kill-bg` is optional.
|
|
|
|
Test arguments
|
|
- kill-bg
|
|
* boolean: Kill background process before running test.
|
|
- profiling-iterations
|
|
* int: Run the extra iterations with enabling method profiling.
|
|
- profiling-sampling
|
|
* int: The interval (0=trace each method, default is 10) of sample profiling in microseconds.
