Power management (PM) driver interfaces. These interfaces are used
|
|
to manage power usage of a platform by monitoring driver activity
|
|
and by placing drivers into reduce power usage modes when the
|
|
drivers are not active.

int "PM time slice (msec)"

|
|
---help---
|
|
The power management module collects activity counts in time slices.
|
|
At the end of the time slice, the count accumulated during that
|
|
interval is applied to an averaging algorithm to determine the
|
|
activity level.
|
|
|
|
CONFIG_PM_SLICEMS provides the duration of that time slice in
|
|
milliseconds. Default: 100 Milliseconds

The averaging algorithm is simply: Y = (An*X + SUM(Ai*Yi))/SUM(Aj),
|
|
where i = 1..n-1 and j= 1..n, n is the length of the "memory",
|
|
Ai is the weight applied to each value, and X is the current
|
|
activity. These weights may be negative and a limited to the
|
|
range of int16_t.
|
|
|
|
CONFIG_PM_MEMORY provides the memory for the algorithm. Default: 2
|
|
CONFIG_PM_COEFn provides weight for each sample. Default: 1

Setting CONFIG_PM_MEMORY=1 disables all smoothing.
