That's what I was trying to say. I wouldn't say zero effect - it definitely can matter. If you start out in powersave at a more efficiency biased EPP value then switching to performan= ce is going to increase power consumption and heat etc. > I wonder if amd-pstate could "simply" hide/disable (i.e. make read-only) > scaling_available_governors AND scaling_governor. Userspace can still change the cpufreq governor from performance to powersa= ve and vice versa. So it should not go away. --=20 You may reply to this email to add a comment.
