2015-06-03hw/pci: introduce PCI Expander Bridge (PXB)Marcel Apfelbaum
PXB is a "light-weight" host bridge whose purpose is to enable the main host bridge to support multiple PCI root buses for pc machines. As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus is a primary bus and can be associated with a NUMA node (different from the main host bridge) allowing the guest OS to recognize the proximity of a pass-through device to other resources as RAM and CPUs. The PXB is composed from: - A primary PCI bus (can be associated with a NUMA node) Acts like a normal pci bus and from the functionality point of view is an "expansion" of the bus behind the main host bridge. - A pci-2-pci bridge behind the primary PCI bus where the actual devices will be attached. - A host-bridge PCI device Situated on the bus behind the main host bridge, allows the BIOS to configure the bus number and IO/mem resources. It does not have its own config/data register for configuration cycles, this being handled by the main host bridge. - A host-bridge sysbus to comply with QEMU current design.

2015-02-27Add specific config options for PCI-E bridgesDavid Gibson
The i82801b11, ioh3420 and xio3130 PCI Express devices are currently included in the build unconditionally. While they could theoretically appear on any target platform with PCI-E, they're pretty unlikely to appear on platforms that aren't Intel derived. Therefore, to avoid presenting unlikely-to-be-relevant devices to the user, add config options to enable these components, and enable them by default only on x86 and arm platforms. (Note that this patch does include these for aarch64, via its inclusion of arm-softmmu.mak).

Looks like dec.c is in pci-host by mistake. Moving it over to pci-bridge. Acked-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
