I dont have much time to look at your code given travel, but did you
try to use your group id instead of the controller's?
i.e:
rtnl_open_byproto(&rth, nl_mgrp(mydiscoveredacpiid), NETLINK_GENERIC)

Yes. It doesn't work if I use my group id here.
In fact, I'm using rtnl_open_byproto(&rth, 1, NETLINK_GENERIC) now.
That's why I said that this demo receives all the broadcasted genetlink
messages.

Ok, by inspection (sorry, still dont have much time) - your kernel code
is sending to group 1; i.e

genlmsg_multicast(skb, 0, 1, GFP_ATOMIC);

you need to change that to send to your assigned id, i.e:
genlmsg_multicast(skb, 0, acpi_event_genl_family.id, GFP_ATOMIC);

Oh, that's the problem.
Great, now it works happily. :).
Jamal, thanks for your help!

Best regards,
