Hello I'm trying to find out if the power consumption relating to the intel_powerclamp driver ("Package Level C-state Idle Injection for Intel CPUs") was ever fixed. I'm current running 5.7 stable and I find my cpu is still consuming 6W of power in any state. It was mentioned in the emails from last year that a Linux driver fixed this issue. Any updates on this issue would be great. I have attached my dmesg for review.
