The new PAPR 2.12 defines a watchdog facility managed via the new H_WATCHDOG hypercall. This adds H_WATCHDOG support which a proposed driver for pseries uses: https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=303120 This was tested by running QEMU with a debug kernel and command line: -append \ "pseries-wdt.timeout=60 pseries-wdt.nowayout=1 pseries-wdt.action=2" and running "echo V > /dev/watchdog0" inside the VM.
