Number of cpu cores change in my systrace output

Question

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 ?

Answer

you can check how many cpu<?> 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
