The PMU/EDAC devices are all PCI devices do I need the 'struct pci_dev *'. I'm not aware of other ways to access these devices. Please enlighten me if I'm missing something.Me enlighten you on Cavium hardware?! You're funny. So I don't know whether the PCI hotplug code can run more than one function upon PCI ID detection. Probably Greg will say, write a multiplexer wrapper. :-)-ENOCONTEXT.... Anyway, pci questions are best asked on the linux-pci at vger list. And yes, all PCI devices end up with a 'struct pci_dev *' automatically.Simple: so they have a PCI ID of a memory contoller and want to hotplug two drivers for it. And those two drivers should remain independent from each other.
Hahahahaha, no. That's crazy, you were right in guessing what my answer was going to be :) greg k-h
