1 This parameter allows the user to set the link (interface) power management. 2 There are 3 possible options: 3 4 Value Effect 5 ---------------------------------------------------------------------------- 6 min_power Tell the controller to try to make the link use the 7 least possible power when possible. This may 8 sacrifice some performance due to increased latency 9 when coming out of lower power states. 10 11 max_performance Generally, this means no power management. Tell 12 the controller to have performance be a priority 13 over power management. 14 15 medium_power Tell the controller to enter a lower power state 16 when possible, but do not enter the lowest power 17 state, thus improving latency over min_power setting. 18
