setting reserveEntireSlot really accomplishes nothing - instead of going to the trouble of computing the value for reserveEntireSlot and then possibly setting *all* functions of the slot as in-use, we can just set the in-use bit only for the specific function being used by a device. Later we will know from the context (the PCI connect flags, and whether we are reserving a specific address or asking for "the next available") whether or not it is okay to allocate other functions on the same slot. Although it's not used yet, we allow specifying "-1" for the function number when looking for the "next available slot" - this is going to end up meaning "return the lowest available function in the slot, but since we currently only provide a function from an otherwise unused slot, "-1" ends up meaning "0".
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
