Hello!
I wanted to write a device driver as kernelmodule, using newbus.
Since there is almost no documentation, I've read some source.
It seems, that I have to do something like:
static device_method_t zivads_methods[] = {
/* interface */
DEVMETHOD(device_identify, zivads_identify),
DEVMETHOD(device_probe, zivads_probe),
DEVMETHOD(device_attach, zivads_attach),
{ 0, 0 }
};
and to use zivads_* functions then.
But this fails because I don't know the right include files - DEVMETHOD
is expanded to unknown funtions
What I'm searching for is some info on how to do this.
Can anyone point me to a SIMPLE device driver module, that does this?
Or any documentation?
Or summarize how exactly stuff is done, e.g. which include files are
needed for the above?
It's very hard to find this things out when starting from scratch :)
When I will have got this working, I would even write a small
manual/introduction, that can be used as an example/manual for other
people, e.g. third party vendors, that want to write drivers for
newbus.
TIA
Alex
