vfio: Add vfio_file_is_group()

2022-10-07T14:10:52Z

This replaces uses of vfio_file_iommu_group() which were only detecting if the file is a VFIO file with no interest in the actual group. The only remaning user of vfio_file_iommu_group() is in KVM for the SPAPR stuff. It passes the iommu_group into the arch code through kvm for some reason.

hisi_acc_vfio_pci: Fix device data address combination problem

2022-09-27T15:30:31Z

The queue address of the accelerator device should be combined into a dma address in a way of combining the low and high bits. The previous combination is wrong and needs to be modified.

hisi_acc_vfio_pci: Fixes error return code issue

2022-09-27T15:30:31Z

During the process of compatibility and matching of live migration device information, if the isolation status of the two devices is inconsistent, the live migration needs to be exited. The current driver does not return the error code correctly and needs to be fixed.
