当系统进入S3状态时，如何阻止设备在SDIO中休眠？ [英] how to block the device sleep in SDIO while system going to S3 state?

问题描述

大家好，

      这个问题是否正确？我不知道，但我想要一些信息。

      当系统进入S3状态（睡眠）时，我的SDIO设备也会进入睡眠状态。但对我而言，睡眠后我的SDIO设备也必须工作（如WIFI WOWLAN）。如何阻止来自Windows的睡眠请求？。

问候，

Arun

解决方案

嗨Arun，

感谢您发布MSDN论坛。

据我所知，我们无法阻止睡觉，  你可以尝试防止睡眠被改变。 

>>"  如何阻止来自Windows的此睡眠请求？。  "

也许您可以阻止系统电源状态更改，电源管理器提供三个例程，通过这些例程，驱动程序可以阻止系统转换到工作状态：

PoSetSystemState ，
PoRegisterSystemState 和
PoUnregisterSystemState 。

如果您有任何其他内容，请随时与我们联系。

最好的问候，

哈特

Hi Arun,

Thank you for posting MSDN forum.

As far as I know we cannot block the sleep,  you can try to prevent the sleep is changed. 

>>"  How to block this sleep request from windows?.  "

Maybe you can prevent the System Power State Changes, the power manager provides three routines through which a driver can prevent system transitions out of the working state: PoSetSystemState, PoRegisterSystemState, and PoUnregisterSystemState.

If you have any something else, please feel free to contact us.

Best Regards,

Hart
