Wake up Time from S3

[ktc]

I don't have access to a board yet but I am very curious about one aspect of the platform. 

I have an application that require low power and I need to put Pine64 into sleep most of the time. (S3). Once in a while, it needs to wake up and do some math calculations and go back to sleep. 

What type of S3 to active timing I should expect? I can optimize the Kernel such that it only has what I need. (No Display, Camera etc.)

Thx

S3 sleep state it is only intel chips.

A64 Soc, haven't got S3 sleep mode.

the Pmic can put the Soc in sleep mode, and wakeup mode.

I see. I studied the AXP803 datasheet and I see that it is possible to trigger a sleep/wake up functionality. I have a few questions:

- Is the A64 driver for this already available?  (i.e. using Sleep/Wake up functionality of AXP803)
- Does the A64 doing STR (Save to Ram) in Sleep Mode?
- What type of Wake up time I should expect? 
- What type of Sleep time I should expect?

The A64 can enter in deep-sleep mode.
