Simple Digital Power Meter(SDPM) clock monitoring.
|
||
|
|
|
||
|
|
SDPM is used to monitor the operating frequency of different clocks and based
|
||
|
|
on operating levels of different clients, the Policy Engine will recommend a
|
||
|
|
new max operating level. The SDPM driver will register with the clock
|
||
|
|
framework for rate change notification of different clocks. These clock rate
|
||
|
|
will be updated to SDPM.
