Do we have some sane way to have user-pluggable sysbus devices on arm? I've played around with that a bit, with the uefi variable service I'm working on. Specifically I'd prefer to *not* have a patch wiring things up in machine type code like this ... https://lore.kernel.org/qemu-devel/20250107153353.1144978-20-kra...@redhat.com/ ... and just use 'qemu -device uefi-vars-sysbus' instead. Something like AcpiDevAmlIfClass but for device tree seems to not exist though. Also apparently AcpiDevAmlIfClass is not used. take care, Gerd
