[Qemu-devel] Is there a way for passing parameter directly to a module

Hi,

Is there a way for passing a parameter directly to a module (i.e. device driver within QEMU), for example file path (when I am working at Full system emulation)?
My goal is to have a device emulation which will be able to read a configuration file that its name is provided in runtime.

Thanks,
Lior Nahmanson

Hi Lior,
Thanks for posting to qemu-devel.  You also posted on my blog.  I saw
and answered there first.  In the future, please post general technical
questions on qemu-devel and not my blog - that way others can help too.

For the record, my answer was that qdev properties (or QOM properties)
are the standard way of passing parameters: -device foo,myarg=1.  There
are many examples, such as in hw/net/e1000.c.

Stefan
