Following this wiki (https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842232/Zynq+UltraScale+MPSoC+Power+Management+-+Linux+Kernel#ZynqUltraScale%EF%BC%8BMPSoCPowerManagement-LinuxKernel-WakeonLAN) I've enabled the PM in petalinux 2019.2, I can suspend correctly the system but then I can't wake it up from the 10G/25G ethernet subsystem.
In the wiki they use these commands to suspend and select the wakeup source:
$ echo enabled > /sys/devices/platform/amba/ff0e0000.ethernet/net/eth0/power/wakeup / Suspend $ echo mem > /sys/power/state
In my case I tried with /sys/devices/platform/amba_pl@0/a0042000.ethernet/net/eth0/power/ but I can't find the wakeup file.
I have only these files:
How can I "wake on lan" from the 10G/25G subsystem?

As can be seen from the AXI ethernet driver wiki, we don't have wake on LAN support
We have this support however in PS GEM driver:
