* pci: Replace pci_find_domain() with more general pci_root_bus_path()David Gibson2013-07-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pci_find_domain() is used in a number of places where we want an id for a whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is that many platforms may support multiple independent host bridges with no hardware supplied notion of domain number. This patch, therefore, replaces calls to pci_find_domain() with calls to a new pci_root_bus_path() returning a string. The new call is implemented in terms of a new callback in the host bridge class, so it can be defined in some way that's well defined for the platform. When no callback is available we fall back on the qbus name. Most current uses of pci_find_domain() are for error or informational messages, so the change in identifiers should be harmless. The exception is pci_get_dev_path(), whose results form part of migration streams. To maintain compatibility with old migration streams, the PIIX PCI host is altered to always supply "0000" for this path, which matches the old domain number (since the code didn't actually support domains other than 0). For the pseries (spapr) PCI bridge we use a different platform-unique identifier (pseries machines can routinely have dozens of PCI host bridges). Theoretically that breaks migration streams, but given that we don't yet have migration support for pseries, it doesn't matter. Any other machines that have working migration support including PCI devices will need to be updated to maintain migration stream compatibility.

* pci: fix path for local includesMichael S. Tsirkin2012-12-171-2/+2
| | | | | | | | | Include dependencies from pci core using the correct path. This is required now that it's in the separate directory. Need to check whether they can be minimized, for now, keep the code as is. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
