Select the Default SATA Link Power Management (LPM) policy to use
for chipsets / "South Bridges" supporting low-power modes. Such
chipsets are ubiquitous across laptops, desktops and servers.
-
- The value set has the following meanings:
+ 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).
+
+ The possible values for the default SATA link power management
+ policies are:
0 => Keep firmware settings
- 1 => Maximum performance
- 2 => Medium power
- 3 => Medium power with Device Initiated PM enabled
- 4 => Minimum power
-
- Note "Minimum power" is known to cause issues, including disk
- corruption, with some disks and should not be used.
+ 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.

- * Limiting Performance Impact
- * ---------------------------
- * C states, especially those with large exit latencies, can have a real
- * noticeable impact on workloads, which is not acceptable for most sysadmins,
- * and in addition, less performance has a power price of its own.
- *
- * As a general rule of thumb, menu assumes that the following heuristic
- * holds:
- * The busier the system, the less impact of C states is acceptable
- *
- * This rule-of-thumb is implemented using a performance-multiplier:
- * If the exit latency times the performance multiplier is longer than
- * the predicted duration, the C state is not considered a candidate
- * for selection due to a too high performance impact. So the higher
- * this multiplier is, the longer we need to be idle to pick a deep C
- * state, and thus the less likely a busy CPU will hit such a deep
- * C state.
- *
- * Currently there is only one value determining the factor:
- * 10 points are added for each process that is waiting for IO on this CPU.
- * (This value was experimentally determined.)
- * Utilization is no longer a factor as it was shown that it never contributed
- * significantly to the performance multiplier in the first place.

- * 2. Disables interrupts for the duration of the coverage collection section.

- * For example, usb_giveback_urb_bh() runs in the BH workqueue with
