Android : bus frequency feature

eishishibusawa — Mon, 06 Mar 2017 08:25:39 GMT

Dear Sir

I want to ask you about the bus frequency feature of Android.

I refer to the AFAQ Rev kk4.4.2_1.0.0-ga, 07/2014.

Q1.

Can I understand that it enters in low bus frequency when the screen is off?

Q2.

What condition does it enter in low bus frequency if it is enabled?

Q3.

Can I select the condition to enter in low bus frequency?

(How can I set the condition?)

Best Regards,

Eishi SHIBUSAWA

Hi Eishi

1. right, as kk4.4.2_1.0.0 is based on L3.0.35 kernel one can refer to

below part of attached L3.0.35 Linux Manual

2. when system is idle, please refer to Chapter 16,18,19 Linux Manul

3. please refer to examples in sect.18.1.1 Software Operation

Best regards
igor
