## Add WoL Support
!!! note
Starting Armbian version **5.77** the Wake-on-LAN support has been added by default. So you might want to upgrade your system via APT to skip this section.

## Kernel Patch
### Kernel
Current gpio-mvebu driver does not implement [irq_set_wake()](https://www.kernel.org/doc/html/v4.14/core-api/genericirq.html?highlight=irq_set_wake#c.irq_chip)
to support GPIO as wakeup source and properly route it to upper interrupt controller (Arm GIC).

## Enabling WOL
!!! note
Latest Armbian images, starting version **5.77**, already have the WoL enabled by default for eth0. So you may skip this step.
Enable the PHY to raise an interrupt when magic packet received :
```
sudo ethtool -s eth0 wol g
```
To make it permanent, create the following file */etc/systemd/system/wol@.service* and copy the following:
