I've registered it using the code below. The registration executes during QEMU launch, the the initialization doesn't. Please where should I add it?
static void ers_io_register_devices(void) { isa_qdev_register(&ers_io_info); ers_io_debug("\n"); } device_init(ers_io_register_devices); Thank you, best regards, Tomas On 22.2.2011 9:48, Markus Armbruster wrote:

This client would simulate the physical environment that the application running inside QEMU should control. To achieve this, I would like to introduce use general IO ports (in a similar way they are used e.g. on ARMs). Please is there a simple way to emulate the general IO ports on pc386? If not, what would be the simplest way to create (i.e. develop) a new device for QEMU? Is there any intro or some simple device, which could be taken as a stub?If you crusty old ISA is okay for you, the ib700 watchdog device (hw/wdt_ib700.c) is really simple. For PCI, maybe try the i6300esb watchdog (hw/wdt_i6300esb.c).
