> Add vfio_pci_dma_buf_find_pfn(), which a VMA fault handler can use to > find a PFN. > > This supports multi-range DMABUFs, which typically would be used to > represent scattered spans but might even represent overlapping or > aliasing spans of PFNs. > > Because this is intended to be used in vfio_pci_core.c, we also need > to expose the struct vfio_pci_dma_buf in the vfio_pci_priv.h header. > > This move also adds a new member, vma_pgoff_adjust; this is consumed > by vfio_pci_dma_buf_find_pfn(), but will be set in a future commit. > Add it now to reduce the number of functions touched by later commits. > > Signed-off-by: Matt Evans <[email protected]>
