# measure.sh <label> [seconds] - (Android root shell) CPU and GPU load of the MobileGL desktop over a
|
|
# window: % of ONE core (so 800 = all 8 cores) for the whole phone, KWin (+Xwayland), plasmashell,
|
|
# Chrome (all its processes), the app's :mobilegl server and its UI process, plus the mean of the
|
|
# kgsl gpu_busy_percentage samples (1/s). The container's processes are visible from Android's
|
|
# /proc (Droidspaces only gives them their own pid namespace).

# Run: su -c "sh /data/local/tmp/anl/measure.sh visible 20" Env: PKG.
