- use custom interation counter since simpleperf is run over entire test - move all setup to @Before so its not recorded by simpleperf - make test activity fullscreen to remove buffer updates from statusbar Bug: 230039226 Test: atest SurfaceFlingerPerfTest Change-Id: Id8c03b4dd32c012f091ab602fff780308420742f
SurfaceFlinger 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 SurfaceFlingerPerfTests:SurfaceFlingerPerfTest -- \
--module-arg SurfaceFlingerPerfTests:instrumentation-arg:kill-bg:=true
Use am instrument
adb shell am instrument -w -r -e class android.surfaceflinger.SurfaceFlingerPerfTest \
-e kill-bg true \
com.android.perftests.surfaceflinger/androidx.test.runner.AndroidJUnitRunner
kill-bgis 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.
