Hi,
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.
Ignore qdev_init_chardev() ...
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.
Use a chardev property (look at serial.c, "isa-serial" device). Then you'll configure it on the qemu command line like this: -chardev $backend,id=some-name-here,more-chardev-parameters -device virtio-rng,chardev=some-name-here HTH, Gerd
