Description:
|
|
|
|
|
The /sys/class/devfreq/.../polling_interval shows and sets
|
|
|
|
|
the requested polling interval of the corresponding devfreq
|
|
|
|
|
object. The values are represented in ms. If the value is
|
|
|
|
|
less than 1 jiffy, it is considered to be 0, which means
|
|
|
|
|
no polling. This value is meaningless if the governor is
|
|
|
|
|
not polling; thus. If the governor is not using
|
|
|
|
|
devfreq-provided central polling
|
|
|
|
|
(/sys/class/devfreq/.../central_polling is 0), this value
|
|
|
|
|
may be useless.
