| VFIO virtual device |
| =================== |
| |
| Device types supported: |
| KVM_DEV_TYPE_VFIO |
| |
| Only one VFIO instance may be created per VM. The created device |
| tracks VFIO groups in use by the VM and features of those groups |
| important to the correctness and acceleration of the VM. As groups |
| are enabled and disabled for use by the VM, KVM should be updated |
| about their presence. When registered with KVM, a reference to the |
| VFIO-group is held by KVM. |
| |
| Groups: |
| KVM_DEV_VFIO_GROUP |
| |
| KVM_DEV_VFIO_GROUP attributes: |
| KVM_DEV_VFIO_GROUP_ADD: Add a VFIO group to VFIO-KVM device tracking |
| KVM_DEV_VFIO_GROUP_DEL: Remove a VFIO group from VFIO-KVM device tracking |
| |
| For each, kvm_device_attr.addr points to an int32_t file descriptor |
| for the VFIO group. |
