Virtualization - Mar 2011 - Developing custom PCI devices in qemu

Hi All

I am interested in developing a custom PCI device for qemu.
For learning purpose, It could be just a very basic device e.g. a device
which just loopbacks the contents from device memory to some system buffer.

Please guide me how such a device can be developed in qemu.
Do qemu have some device model or device framework for developing custom
virtual devices?

Any documentation and samples will be very helpful.



Thanks & Regards

One of the simpler PCI devices in the tree is the i6300esb watchdog, in
hw/wdt_i6300esb.c.

I'm afraid you need to figure it out from code.
