Messages in this thread Patch in this message | | | From | Eric Auger <> | Subject | [RFC v6 06/16] VFIO: Introduce vfio_device_external_ops | Date | Mon, 13 Apr 2015 14:29:21 +0200 |
| |
New bus callbacks are introduced. They correspond to external functions. To avoid messing up the main vfio_device_ops struct, a new vfio_device_external_ops struct is introduced.
