The function that auto-assigns PCI addresses was written with the hardcoded assumptions that any PCI bus would have slots available starting at 1 and ending at 31. This isn't true for many types of controllers (some have a single slot/port at 0, some have slots/ports from 0 to 31). This patch updates that function to remove the hardcoded assumptions. It will properly find/assign addresses for devices that can only connect to pcie-(root|downstream)-port (which have minSlot/maxSlot of 0/0) or a pcie-switch-upstream-port (0/31). It still will not auto-create a new bus of the proper kind for these connections when one doesn't exist, that task is for another day.
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.
