PCI IDs for qemu
|
|
================
|
|
|
|
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.
|

|
|
|
|
The 1000 -> 10ff device ID range is used as follows for virtio-pci devices.

Note that this allocation separate from the virtio device IDs, which are
|
|
maintained as part of the virtio specification.

|
1af4:1002 balloon device
|
|
1af4:1003 console device
|
|
1af4:1004 SCSI host bus adapter device
|
|
1af4:1005 entropy generator device
|
|
1af4:1009 9p filesystem device
|
|
|
|
1af4:10f0 Available for experimental usage without registration. Must get
|
|
to official ID when the code leaves the test lab (i.e. when seeking
|
|
1af4:10ff upstream merge or shipping a distro/product) to avoid conflicts.
|
|
|
|
1af4:1100 Used as PCI Subsystem ID for existing hardware devices emulated
|
|
by qemu.
|
|
|
|

|
|
|
|
1b36:0001 PCI-PCI bridge
|
