“All CPUs” would probably be 99.9999% accurate. It’s just one of those fundamental functions you want in a processor. Whether it’s exposed in the OS is a different matter.

AMD doesn't have it. I just confirmed by grepping through dmesg and journalctl -b, the only time it appears is due to UPS driver notifications (unrelated).

Cortex-A includes a watchdog so yeah.
