This parameter allows the user to set the link (interface) power management.
|
||
|
|
There are 3 possible options:
|
||
|
|
|
||
|
|
Value Effect
|
||
|
|
----------------------------------------------------------------------------
|
||
|
|
min_power Tell the controller to try to make the link use the
|
||
|
|
least possible power when possible. This may
|
||
|
|
sacrifice some performance due to increased latency
|
||
|
|
when coming out of lower power states.
|
||
|
|
|
||
|
|
max_performance Generally, this means no power management. Tell
|
||
|
|
the controller to have performance be a priority
|
||
|
|
over power management.
|
||
|
|
|
||
|
|
medium_power Tell the controller to enter a lower power state
|
||
|
|
when possible, but do not enter the lowest power
|
||
|
|
state, thus improving latency over min_power setting.
