43 bus-specific fields that cannot be generalized.
45 The most common example of this are device ID structures. A driver
46 typically defines an array of device IDs that it supports. The format
47 of these structures and the semantics for comparing device IDs are
48 completely bus-specific. Defining them as bus-specific entities would

8 The vfio-pci driver exists as a device agnostic driver using the
10 handling to provide isolated device access to userspace. While the
11 vfio-pci driver does include some device specific support, further
12 extensions for yet more advanced device specific features are not
