[Qemu-devel] virtio-rng

Hi folks,

I'm writing a virtio-rng host-side driver for qemu-kvm, and I've got
something up and running that works, and will pass data gathered from a
char device on the host through to the virtio-rng driver on a guest copy
of linux.

Ultimately it'll get its entropy from egd as well, but for now I'd like
to solve the issue in hw/qdev.c.

in qdev_init_chardev() the return value is picked based upon the name of
the device. For now, I've added a third 'if clause' to match for my
driver and pass through the CharDriverState * fron vl.c for my rng
driver, however I'd like to solve this properly.

I think a simple name->pointer type matching system would work fine,
however I'd like to know if anyone else has sorted this yet, or if I
should be doing things differently altogether.

also, what does '_hds' stand for? eg. 'virtcon_hds'[]

Thanks,

- -Ian
