Wake on lan support

Unread postby mad_ady » Fri Jun 01, 2018 1:46 pm

Here's an interesting idea. Since the ethernet port is connected directly to the soc, and not going through usb, it might be easier to support wake on lan. From what I've searched, rk3399 does not officially support it, but maybe it can be done in a similar manner to how "wake on ir" was done on the c2 (e.g put the soc in the lowest power mode with only uboot running and have it wake the system up on a correct signal/packet).
Any ideas about fesability/lack of fesabilith for this?

I don't think you can shutdown the SATA, without being able to do so there would be no real power savings.

The SATA is PCIe based and should support standard PCIe power management. Any attached devices should also support SATA power management commands. So, both the interface and devices should achieve low power operation.

I tried to shut the power down through sysfs but haven't been able to.
