Hi everyone!
Could someone please point out some links to a good documentation and/or tutorial on how to write hardware devices for qemu?

I have been reading through the parallel & ne2k code and - although it is not that hard - just do not get all the information necessary it seems.

are there some places, where functions like
- qemu_chr_ioctl
- cpu_register_io_memory
- pci_register_io_memory
- pci_register_device
- etc.

are described shortly (or even in more detail ;-)  )?

My current problem is the following: While loading a module in the client-os it get the error

"cannot reserve PCI memory region"

(from the dadwifi (yes - not madwifi) ath_pci module).

What do i have to do in order to get this right?

cheers!
