It seems like I am only capable of changing the frequency of all the CPU cores at the same time,on AGX xavier.
For example:
echo “userspace” > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo > /sys/devices/system/cpu/cpu1/cpufreq/scaling_setspeed
will make all CPU cores that are currently on go to that frequency, not just CPU core 1.
I have been using this wiki for reference:
Please refer to NVIDIA Jetson Linux Developer Guide : Clock Frequency and Power Management | NVIDIA Docs
Didn’t help much and didn’t see any solution to this problem.
If can’t find it from that section, then means it’s not supportred.
I was worried because I didn’t find it, not because it wasn’t supported
why it doesn’t support individual cpu frequency adjustment
Why it’s required? Any use case?

You could try to use NVIDIA Nsight Systems | NVIDIA Developer to analyze and optimize software performance.
