Vendor driver should decide whether to partition data section and how to
partition the data section. Vendor driver should return data_offset
accordingly.
For user application, data is opaque. User should write data in the same

- Moved PCI device functions to pci file.
- Added iteration to get dirty page bitmap until bitmap for all requested pages
are copied.
Thanks,

Kirti Wankhede (13):
vfio: KABI for migration interface
vfio: Add function to unmap VFIO region
vfio: Add vfio_get_obje
vice data and dirty pages bitmap.
Vendor driver should decide whether to partition data section and how to
partition the data section. Vendor driver should return data_offset
accordingly.
For user application, data is opaque. User should write data in the same
order as received.
