2015-10-19hw/pci: Introduce pci_requester_id()Pavel Fedin
For GICv3 ITS implementation we are going to use requester IDs in KVM IRQ routing code. This patch introduces reusable convenient way to obtain this ID from the device pointer. The new function is now used in some places, where the same calculation was used. MemTxAttrs.stream_id also renamed to requester_id in order to better reflect semantics of the field.

2015-07-06vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devicesGabriel Laupre
Fix pba_offset initialization value for Chelsio T5 Virtual Function device. The T5 hardware has a bug in it where it reports a Pending Interrupt Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead of the 0x1000 that the hardware actually uses internally. As the hardware doesn't return the correct pba_offset value, add a quirk to instead return a hardcoded value of 0x1000 when a Chelsio T5 VF device is detected. This bug has been fixed in the Chelsio's next chip series T6 but there are no plans to respin the T5 ASIC for this bug. It is just documented in the T5 Errata and left it at that.

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.

2014-02-10pci/pcie: convert PCIE hotplug to use hotplug-handler APIIgor Mammedov
Split pcie_cap_slot_hotplug() into hotplug/unplug callbacks and register them as "hotplug-handler" interface implementation of PCIE_SLOT device. Replace pci_bus_hotplug() wiring with setting link on PCI BUS "hotplug-handler" property to PCI_BRIDGE_DEV device. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

qbus_reset_all can be used instead. There is no semantic change because pcibus_reset returns 1 and takes care of the device tree traversal. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-12-01xen-pvdevice: make device-id property compulsoryPaul Durrant
The intention of the Xen PV device is that it is used as a parent device for PV drivers in Xen HVM guests and the set of PV drivers that bind to the device is determined by its device ID (and possibly vendor ID and revision). As such, the device should not have a default device ID, it should always be supplied by the Xen toolstack.
