Red Hat, Inc. donates a part of its device ID range to QEMU, to be used for
|
|
|
|
|
virtual devices. The vendor IDs are 1af4 (formerly Qumranet ID) and 1b36.
|
|
|
|
|
|
|
|
|
|
Contact Gerd Hoffmann <kraxel@redhat.com> to get a device ID assigned
|
|
|
|
|
for your devices.

|
1af4 vendor ID
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
The 1000 -> 10ff device ID range is used as follows for virtio-pci devices.
|
|
|
|
|
Note that this allocation is separate from the virtio device IDs, which are
|
|
|
|
|
maintained as part of the virtio specification.

|
1af4:1000
|
|
|
|
|
network device (legacy)
|
|
|
|
|
1af4:1001
|
|
|
|
|
block device (legacy)
|
|
|
|

|
|
1af4:1003
|
|
|
|

|
|
|
|

|
|
|

|
|
|

1af4:1009
|

|
9p filesystem device (legacy)
|
|
|
|
|
1af4:1012
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
1af4:1040 to 1af4:10ef
|
|
|
|
|
ID range for modern virtio devices. The PCI device
|
|
|
|
|
ID is calculated from the virtio device ID by adding the
|
|
|
|
|
0x1040 offset. The virtio IDs are defined in the virtio
|
|
|
|
|
specification. The Linux kernel has a header file with
|
|
|
|
|
defines for all virtio IDs (``linux/virtio_ids.h``); QEMU has a
|
|
|
|
|
copy in ``include/standard-headers/``.
|
|
|
|
|
|
|
|
|
|
1af4:10f0 to 1a4f:10ff
|
|
|
|
|
Available for experimental usage without registration. Must get
|
|
|
|
|
official ID when the code leaves the test lab (i.e. when seeking
|
|
|
|
|
upstream merge or shipping a distro/product) to avoid conflicts.
|
|
|
|
|
|
|
|
|
|
1af4:1100
|
|
|
|
|
Used as PCI Subsystem ID for existing hardware devices emulated
|
|
|
|
|
by QEMU.
|
|
|
|
|
|
|
|
|
|
1af4:1110
|

|
|
|
ivshmem device (shared memory, ``docs/specs/ivshmem-spec.txt``)
