help
Select the Default SATA Link Power Management (LPM) policy to use
for mobile / laptop variants of chipsets / "South Bridges".
The value set has the following meanings:
0 => Keep firmware settings
1 => Maximum performance
2 => Medium power
3 => Medium power with Device Initiated PM enabled
4 => Minimum power
Each policy combines power saving states and features:
- Partial: The Phy logic is powered but is in a reduced power
state. The exit latency from this state is no longer than
10us).
- Slumber: The Phy logic is powered but is in an even lower power
state. The exit latency from this state is potentially
longer, but no longer than 10ms.
- DevSleep: The Phy logic may be powered down. The exit latency from
this state is no longer than 20 ms, unless otherwise
specified by DETO in the device Identify Device Data log.
- HIPM: Host Initiated Power Management (host automatically
transitions to partial and slumber).
- DIPM: Device Initiated Power Management (device automatically
transitions to partial and slumber).
Note "Minimum power" is known to cause issues, including disk
corruption, with some disks and should not be used.
The possible values for the default SATA link power management
policies are:
0 => Keep firmware settings
1 => No power savings (maximum performance)
2 => HIPM (Partial)
3 => HIPM (Partial) and DIPM (Partial and Slumber)
4 => HIPM (Partial and DevSleep) and DIPM (Partial and Slumber)
5 => HIPM (Slumber and DevSleep) and DIPM (Partial and Slumber)
Excluding the value 0, higher values represent policies with higher
power savings.
