[DisableWatchDog and debug=0x100] Clarifications and differences

[dreamwhite]

Hi there,
I was reading OpenCore Configuration.pdf about config.plist/Misc/Debug/DisableWatchDog.
According to it:

In section 12.5 Tips and Tricks it's suggested to the end user, in order to debug boot failure, to enable DisableWatchDog feature to prevent automatic reboot.

At this point I'm asking my self: what's the purpose of debug=0x100 boot-arg which prevents automatic reboot (the most reliable source is dortania's guide), when DisableWatchDog (at least according to Configuration.pdf) does the same job? Am I missing something?
Thank you so much for the clarifications

There are many watchdogs. This one is for UEFI, debug=0x100 is for SMC/XNU.

Alright, so how can I choose whether should I use or not config.plist/Misc/Debug/DisableWatchDog? Is there a list of particular firmwares that may require this option to be enabled?

Watchdog interface is standardised by the UEFI spec. Most firmwares have a value configured between 3 and 10 minutes. I would say it is safe to disable watchdog unless you really need it for whatever reasons.
