First, we have HostPCIDevice that help to access one PCI device of the host. Then, there are several additions in the QEMU code. One is qemu_run_one_timer to run a specific timer. It is used by PCI passthrough to run a timer about power management. Another is pci_check_bar_overlap. There are also several change in pci_ids and pci_regs. Last part, but not least, the PCI passthrough device himself. Cut in 3 parts (or file), there is one to take care of the initialisation of a passthrough device. The second one handle everything about the config address space, there are specifics functions for every config register. The third one is to handle MSI. I'm still working on setting a PCI passthrough device through QMP from libxl (xen tool stack). It is just a call to device_add, with the driver parametter hostaddr="0000:00:1b.0". There is some minor things missing: - copyright header - PCI IO space multiplexer Regards, Anthony PERARD (11): Introduce HostPCIDevice to access a pci device on the host. qemu-timer: Introduce qemu_run_one_timer pci_ids: Add INTEL_82599_VF id. pci_regs: Fix value of PCI_EXP_TYPE_RC_EC. pci_regs: Add PCI_EXP_TYPE_PCIE_BRIDGE pci.c: Add pci_check_bar_overlap host-pci-device: Add host_pci_find_ext_cap_offset Introduce Xen PCI Passthrough, qdevice (1/3) Introduce Xen PCI Passthrough, PCI config space helpers (2/3) Introduce Xen PCI Passthrough, MSI (3/3) config/make: Introduce --enable-xen-pci-passthrough, built it.
