Brett Creeley bb500dbe2a vfio/pds: Add VFIO live migration support ... Add live migration support via the VFIO subsystem. The migration implementation aligns with the definition from uapi/vfio.h and uses the pds_core PF's adminq for device configuration. The ability to suspend, resume, and transfer VF device state data is included along with the required admin queue command structures and implementations. PDS_LM_CMD_SUSPEND and PDS_LM_CMD_SUSPEND_STATUS are added to support the VF device suspend operation. PDS_LM_CMD_RESUME is added to support the VF device resume operation. PDS_LM_CMD_STATE_SIZE is added to determine the exact size of the VF device state data. PDS_LM_CMD_SAVE is added to get the VF device state data. PDS_LM_CMD_RESTORE is added to restore the VF device with the previously saved data from PDS_LM_CMD_SAVE. PDS_LM_CMD_HOST_VF_STATUS is added to notify the DSC/firmware when a migration is in/not-in progress from the host's perspective. The DSC/firmware can use this to clear/setup any necessary state related to a migration.
