The device is populated by the cpu_freq driver, which is used to control frequency scaling. Most cloud environments have shared tenancy and disable the feature to ensure one user can’t scale down the CPU for other tenants.

Is there no way to disable setting the CPU frequency?

I am not sure, but in my experience the driver is not present and not loadable.

Regardless, the max cpu frequency is not equal to tsc frequency on newer Intel CPUs, so the number is meaningless.
