It seems like I am only capable of changing the frequency of all the CPU cores at the same time.
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.
Also, it is interesting to note that when setting “userspace” to a a file path such as /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor, it also makes all cores reflect a “userspace” mode, and not just core 1 as shown in the file path. Is this normal? Is there any way to change a single core frequency?
