2017-01-24PCI/migration merge vmstate_pci_device and vmstate_pcie_deviceDr. David Alan Gilbert
The vmstate_pci_device and vmstate_pcie_devices differ just in the size of one buffer; combine the two using a _TEST macro. I think this is safe as long as everywhere which currently uses either of these two uses the right type. One thing that concerns me is that some places use pci_device_load/save which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE macro - how are they getting the same irq mangling? This passes a smoke test migrate of: ./x86_64-softmmu/qemu-system-x86_64 -M pc,accel=kvm -m 1024 ./littlefed20.img -device e1000e -device virtio-net -device e1000 -device virtio-rng -device megasas -device megasas-gen2 -device ioh3420 -device nec-usb-xhci to an unmodified qemu.

2017-01-10virtio-pci: address space translation service (ATS) supportJason Wang
This patches enable the Address Translation Service support for virtio pci devices. This is needed for a guest visible Device IOTLB implementation and will be required by vhost device IOTLB API implementation for intel IOMMU. Cc: Michael S.

2014-10-15qdev: HotplugHandler: Rename unplug callback to unplug_requestIgor Mammedov
'HotplugHandler.unplug' callback is currently used as async call to issue unplug request for device that implements it. Renaming 'unplug' callback to 'unplug_request' should help to avoid confusion about what callback does and would allow to introduce 'unplug' callback that would perform actual device removal when guest is ready for it.

2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
