Currently the final instance_size of VFIO_PCI_BASE is sizeof(PCIDevice).
It should be sizeof(VFIOPCIDevice), VFIO_PCI uses same structure as
base class VFIO_PCI_BASE, so no need to set its instance_size explicitly.
This isn't catastrophic only because VFIO_PCI_BASE is an abstract class.

A log_mask!() macro is provided which expects similar arguments as the

To maximize code reuse the macro is just a thin wrapper around

Adding -pie to LDFLAGS caused s390-ccw.img to become dynamically linked.
By using -static-pie it will be linked statically like other bios.

Add the helper function cpr_get_fd_param, to use when preserving
a file descriptor that is opened externally and passed to QEMU.
cpr_get_fd_param returns a descriptor number either from a QEMU
command-line parameter, from a getfd command, or from CPR state.
When a descriptor is passed to new QEMU

Save the iommu and vfio device fd in CPR state when it is created.
After CPR, the fd number is found in CPR state and reused.

Save the MSI message area as part of vfio-pci vmstate, and preserve the
interrupt and notifier eventfd's. migrate_incoming loads the MSI data,
then the vfio-pci post_load handler finds the eventfds in CPR state,
rebuilds vector data structures, and attaches the interrupts to the new
KVM instance.

cpr-transfer will use the device name as a key to find the value
of the device descriptor in new QEMU. However, if the descriptor
number is specified by a command-line fd parameter, then
vfio_device_get_name creates a name that includes the fd number.
This causes a chicken-and-egg problem: new QEM
Use IOMMU_IOAS_MAP_FILE when the mapped region is backed by a file.
Such a mapping can be preserved without modification during CPR,
because it depends on the file's address space, which does not change,
rather than on the process's address space, which does change.

Register a vfio iommufd container and device for CPR, replacing the generic
CPR register call with a more specific iommufd register call. Add a
blocker if the kernel does not support IOMMU_IOAS_CHANGE_PROCESS.
This is mostly boiler plate. The fields to to saved and restored are added

Move event_notifier_init calls to a helper vfio_notifier_init.
This version is trivial, but it will be expanded to support CPR
in subsequent patches. No functional change.

Hi Arpit,
Sorry for slow response. I got behind on reviews in general and missed
t
During cpr-transfer load in new QEMU, the vfio_memory_listener causes
spurious calls to map and unmap DMA regions, as devices are created and
the address space is built. This memory was already already mapped by the
device in old QEMU, so suppress the map and unmap callbacks during incoming
CPR.
