I have written a simulated driver for a PCI board and am looking for a clean way to use the driver. Currently, I am setting the PCI ids to PCI_ANY_ID and only allowing a single probe call to go through using a global variable (concurrency issues but I don't care for the simulation).
static int n
...
static int fake_board_probe(struct pci_dev *pdev, const struct pci_device_id *ent)
{
if (n == 1)
return -1;
n = 1;
...
}
static int fake_board_init(void)
{
n = 0;
....
}
I want to do a cleaner job of this and wanted to write a PCI bridge driver that actually registers the devices with the correct IDs that I need. This also gives me the advantage of being able to register multiple devices which is a useful for the simulation I am working on.
Can anyone point me in the right direction for this? Most of the code (eg. struct pci_controller) seem to be architecture specific.
The code is available for anyone interested at:

Thanks and best regards.
