Hello, Pardon me for asking few basic questions, but I'm trying to understand the basics of the PCI hot-plugging: 1) From what I understand, Linux kernel does not use the PCI resource allocation done by the BIOS or the boot loader. Rather it enumerates the PCI buses and devices again and thus the PCI bus numbers and the resources that are allocated may differ from what was done by the BIOS, right? 2) Now as per my understanding when a new device is added later on [and that device may a whole new PCI tree including PCI bridges and other devices on it], there will be a need to allocate PCI bus numbers, and PCI resources to the new devices. As far as I understand, the PCI bus numbers needs to be within the range of subordinate bus numbers of the parent PCI bridges, the same is also true for PCI memory resources I think. Hence in a nutshell, there will be a need for having reserved "holes" in the PCI resource space. Is my understanding correct? 3) What approach does Linux take towards dealing with the above situation? I'd appreciate if you could please point me to appropriate links or code references...
