Hello,

I already posted this message some month ago, but I never got an answer.
Either I am at the wrong
mailing-list, or the message did not arrive properly.
But anyway, here's my question:

I want to create a driver for a custom-made PCI-device. This device has
always been
put directly into the kernel (NetBSD 1.5.1 back then), and it worked
properly.
Now, our software-supplier upgraded to NetBSD 1.6.1 and the driver has to be
rewritten.
Since 1.6.1 has kernel module support, it is unlogical to hack the driver
into the kernel again.

Here's the problem:

In the kernel-version of the software, 3 device-nodes where created:
1 for the PCI communication (/dev/pciDevice0)  and 2 modem interfaces
(/dev/modem0 and /dev/modem1), 
present on the PCI device.
If I create a kernel-module, only the 1st device-node (/dev/pciDevice0) will
be created :

-------------- SAMPLE CODE -------------------

MOD_DEV("pciDevice", LM_DT_CHAR, -1, &pciDevice_cdevsw);

int device_pci_lkmmatch(struct pci_attach_args *pa)
{
  if (device_pci_match(NULL, NULL, pa))
  {
    struct device *sc = (struct device *) device_lkmalloc();
    if (sc != NULL)
    {
      printf("%s at pci%u", sc->dv_xname, pa->pa_bus);
      pciprint(pa, NULL);
      device_pci_attach(NULL, sc, pa);
    }
  }

  return 0;
}


static int device_lkmload(struct lkm_table *lkmt, int cmd)
{
  int error;
  struct pci_attach_args paa;
  
  if (lkmexists(lkmt))
  {
    return (EEXIST);
  }

  (void)pci_find_device(&paa, device_pci_lkmmatch);
  
  if (device_counter == 0)
  {
    return(ENXIO);
  }

  if ((error = modemIfattach ()))
  {
    return error;
  }
  return 0;
}

-------------- END SAMPLE CODE -------------------

Can anyone tell me how I can create the 2 modem-interfaces, accessed through
the function "modemIfattach ()" ?
The 'modload' function returns the major device-number for my PCI-device,
but NOT for my
2 modem-interfaces.

Thanks,

Sander.
