comment "NVIDIA DEVFREQ Governors"
config DEVFREQ_GOV_POD_SCALING
tristate "Power On Demand Scaling"
help
Sets the frequency based on two properties:
(1) The governor receives activity throughput hints that
indicate whether scaling up or down is required
(2) the load of the devices is estimated using busy times
from device profile to determine if the frequency should
be altered.
config DEVFREQ_GOV_WMARK_SIMPLE
tristate "Simple Watermark"
help
Sets the frequency based on monitor watermark events.
This governor returns the next frequency from frequency table
based on type watermark event.
config DEVFREQ_GOV_WMARK_ACTIVE
tristate "Active Watermark"
help
Sets the frequency based on monitor watermark events.
This governor calculates relation between current load and
target load. The next frequency is calculated by multiplying
this relation with the current frequency.
The watermark values are updated so that the watermarks are
triggered when the above algorithm would change the frequency.
