Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/hw/watchdog?h=spice_video_codecs 2022-09-29T09:40:28+00:00 2022-09-29T09:40:28+00:00 Paolo Bonzini 2022-09-10T11:44:47+00:00 urn:sha1:5433af7697ba97531d97e16e721cfe8a90722198 This was deprecated in 6.2 and is ready to go. It removes quite a bit of code that handled the registration of watchdog models.

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.

Introduce ast1030 object class and increse the number of regs(offset) of ast1030 model.

This makes -watchdog-action explicitly a shortcut for "-action watchdog", so that "-watchdog-action" and "-action watchdog" override each other based on the position on the command line; previously, "-action watchdog" always won.

Reserved regions are adjusted, while in other cases the mutability or behaviour of fields change. Introduce a callback to sanitize the value on writes to ensure model behaviour reflects the hardware.
