>Watchdogs exist on MCUs but also on some "proper" computers
All modern computers have watchdog. You can check your logs
`journalctl -b | grep watchdog`

So these days you can find a variation on the TCO timer watchdog in most PCs, even if the exact implementation varies so we now have a bunch of drivers for the different variants.
In both cases they do have software watchdogs (NMI based) which relies on a hardware timer triggering an NMI in the kernel. But that relies on the NMI handler still working, which is not as good as a real HW watchdog.
For whatever reason, it's enabled on my laptop despite it obviously not having IPMI support :)
