Number of cpu cores change in my systrace output I have 4 cores cpu on my device,
but each time I use this command line to genetrate a systrace file :
python C:/Users/BJI/AppData/Local/Android/Sdk/platform-tools/systrace/systrace.py freq idle -o C:/Users/BJI/Desktop/systrace

I get a different number of cores (2 or sometimes 1 core cpu),
is it only the number of active cores ?
you can check how many cpu&lt;?&gt; under  /sys/devices/system/cpu/
for example, If CPU has two cores, there should be
/sys/devices/system/cpu/cpu0

/sys/devices/system/cpu/cpu1
