Suspend to RAm query

Hi All,

I have a very basic query w.r.t the place to handle the standby/suspend process for the devices in the system.

Should it be done at the driver level or in the machine/platform specific code ?

There are instances where I need some specific functionality in the standby mode, or some extra functionality
in the suspend mode at the device level. Is that the reason for differentiating between the suspend and standby at
the platform code level, because in platform code we get different states signifying a suspend or a standby ?

Thanks
Deepak

Hi,

Yes, it is.

The platform suspend callbacks in strcut platform_suspend_ops (as defined in include/linux/suspend.h) take a suspend_state_t argument indicating what state is being requested. You can get the information from there, if I understood your problem description correctly.

Thanks,
Rafael
