Hello,

I cannot load the wireguard module.

Loading the module provides no diagnostic other than 'No such device'.

Please provide maningful diagnostics for loading software-only driver,
clearly there is no particular device needed.

Can you tell us more ? Were you able to load it before ?
Can you provide your .config ?

I just gave it a try on my powerpc 8xx (ppc32) as built-in (I don't use 
modules) and it seems to probe properly:

[    7.547390] wireguard: allowedips self-tests: pass
[    7.607224] wireguard: nonce counter self-tests: pass
[    7.776594] wireguard: ratelimiter self-tests: pass
[    7.781723] wireguard: WireGuard 1.0.0 loaded. See www.wireguard.com 
for info
rmation.
[    7.789570] wireguard: Copyright (C) 2015-2019 Jason A. Donenfeld

Reportedly it worked on 6.5.9 kernel but with a 6.4 distribution kernel
I have available it does not work either.

Attaching the config.
