11  * enum virtio_pcidev_ops - virtual PCI device operations
14  *	the @data field should be filled in by the device (in little endian).
15  * @VIRTIO_PCIDEV_OP_CFG_WRITE: write config space, size is 1, 2, 4 or 8;
16  *	the @data field contains the data to write (in little endian).

19  * @VIRTIO_PCIDEV_OP_MMIO_WRITE: write BAR mem/pio, size can be variable;
20  *	the @data field contains the data to write (in little endian).
22  *	the @data field only has one byte (unlike @VIRTIO_PCIDEV_OP_MMIO_WRITE)
23  * @VIRTIO_PCIDEV_OP_INT: legacy INTx# pin interrupt, the addr field is 1-4 for
25  * @VIRTIO_PCIDEV_OP_MSI: MSI(-X) interrupt, this message basically transports
26  *	the 16- or 32-bit write that would otherwise be done into memory,
27  *	analogous to the write messages (@VIRTIO_PCIDEV_OP_MMIO_WRITE) above
44  * struct virtio_pcidev_msg - virtio PCI device operation
46  * @bar: the bar (only with BAR read/write messages)
48  * @size: the size of the read/write (in bytes)
49  * @addr: the address to read/write
50  * @data: the data, normally @size long, but just one byte for
54  * @data values will often be in little endian (see the ops above.)
