You can read a little bit more about active mode at https://www.kernel.org/doc/html/latest/admin-guide/pm/amd-pstate.html What you should be doing isn't trying to set specific frequency targets, but rather you should change the values of 'energy_performance_preference' to m= eet the needs for your workload. --=20 You may reply to this email to add a comment.
