Ok, my driver is for a specific cPCI biard which we have developed here. I want the Linux Kernel to tell me when this board is inserted and/or removed. I am running on a 700Mhz PIII with a 2.4.18-3 Kernel (Red Hat 7.3) My driver is written with a call to pci_module_init in the init routine wherein I specify a probe and remove routine. According to Linux Device Drivers 2nd edition (pages 489 - 493), As long as the HW supports hot swap, I should get called automatically whenevr one of the devices (vendor ID device ID) which I specified in my table gets inserted or ejected. Am I totaly wrong about this? I am not trying to write a driver for a hotplug controller but for a device.
Thanks in advance.

Cced back to lkml as I hate taking things off-line unless it's necessary, archives are your friend.

No, that's enough to register your driver as a PCI driver. I'm guessing your pci hotplug controller looks like a PCI device?

See drivers/hotplug/pci_hotplug.h for the interface that a pci hotplug controller driver needs to interface with (specifcly the pci_hp_register() and pci_hp_unregister() functions are what you need).

I'm confused, are you talking about a normal PCI card driver, or a PCI Hotplug controller driver? What exactly does your driver do? Does it talk to a specific PCI card, or does it control power to PCI slots?
