5 Red Hat, Inc. donates a part of its device ID range to qemu, to be used for
6 virtual devices. The vendor IDs are 1af4 (formerly Qumranet ID) and 1b36.
8 Contact Gerd Hoffmann <kraxel@redhat.com> to get a device ID assigned
14 The 1000 -> 10ff device ID range is used as follows for virtio-pci devices.
15 Note that this allocation separate from the virtio device IDs, which are
16 maintained as part of the virtio specification.
18 1af4:1000 network device (legacy)
19 1af4:1001 block device (legacy)
20 1af4:1002 balloon device (legacy)
21 1af4:1003 console device (legacy)
22 1af4:1004 SCSI host bus adapter device (legacy)
23 1af4:1005 entropy generator device (legacy)
24 1af4:1009 9p filesystem device (legacy)
25 1af4:1012 vsock device (bug compatibility)
27 1af4:1040 Start of ID range for modern virtio devices. The PCI device
28 to ID is calculated from the virtio device ID by adding the
29 1af4:10ef 0x1040 offset. The virtio IDs are defined in the virtio
30 specification. The Linux kernel has a header file with
31 defines for all virtio IDs (linux/virtio_ids.h), qemu has a
32 copy in include/standard-headers/.
34 1af4:10f0 Available for experimental usage without registration. Must get
35 to official ID when the code leaves the test lab (i.e. when seeking
36 1af4:10ff upstream merge or shipping a distro/product) to avoid conflicts.
38 1af4:1100 Used as PCI Subsystem ID for existing hardware devices emulated
41 1af4:1110 ivshmem device (shared memory, docs/specs/ivshmem-spec.txt)
43 All other device IDs are reserved.
48 The 0000 -> 00ff device ID range is used as follows for QEMU-specific
49 PCI devices (other than virtio):
51 1b36:0001 PCI-PCI bridge
52 1b36:0002 PCI serial port (16550A) adapter (docs/specs/pci-serial.txt)
53 1b36:0003 PCI Dual-port 16550A adapter (docs/specs/pci-serial.txt)
54 1b36:0004 PCI Quad-port 16550A adapter (docs/specs/pci-serial.txt)
55 1b36:0005 PCI test device (docs/specs/pci-testdev.txt)
56 1b36:0006 PCI Rocker Ethernet switch device
57 1b36:0007 PCI SD Card Host Controller Interface (SDHCI)
58 1b36:0008 PCIe host bridge
59 1b36:0009 PCI Expander Bridge (-device pxb)
60 1b36:000a PCI-PCI bridge (multiseat)
61 1b36:000b PCIe Expander Bridge (-device pxb-pcie)
62 1b36:000d PCI xhci usb host adapter
63 1b36:000f mdpy (mdev sample device), linux/samples/vfio-mdev/mdpy.c
64 1b36:0010 PCIe NVMe device (-device nvme)
65 1b36:0011 PCI PVPanic device (-device pvpanic-pci)
66 1b36:0012 PCI ACPI ERST device (-device acpi-erst)
68 All these devices are documented in docs/specs.
70 The 0100 device ID is used for the QXL video card device.
