1================ 2PCI IDs for QEMU 3================ 4 5Red Hat, Inc. donates a part of its device ID range to QEMU, to be used for 6virtual devices. The vendor IDs are 1af4 (formerly Qumranet ID) and 1b36. 7 8Contact Gerd Hoffmann <kraxel@redhat.com> to get a device ID assigned 9for your devices. 10 111af4 vendor ID 12-------------- 13 14The 1000 -> 10ff device ID range is used as follows for virtio-pci devices. 15Note that this allocation is separate from the virtio device IDs, which are 16maintained as part of the virtio specification. 17 181af4:1000 19 network device (legacy) 201af4:1001 21 block device (legacy) 221af4:1002 23 balloon device (legacy) 241af4:1003 25 console device (legacy) 261af4:1004 27 SCSI host bus adapter device (legacy) 281af4:1005 29 entropy generator device (legacy) 301af4:1009 31 9p filesystem device (legacy) 321af4:1012 33 vsock device (bug compatibility) 34 351af4:1040 to 1af4:10ef 36 ID range for modern virtio devices. The PCI device 37 ID is calculated from the virtio device ID by adding the 38 0x1040 offset. The virtio IDs are defined in the virtio 39 specification. The Linux kernel has a header file with 40 defines for all virtio IDs (``linux/virtio_ids.h``); QEMU has a 41 copy in ``include/standard-headers/``. 42 431af4:10f0 to 1a4f:10ff 44 Available for experimental usage without registration. Must get 45 official ID when the code leaves the test lab (i.e. when seeking 46 upstream merge or shipping a distro/product) to avoid conflicts. 47 481af4:1100 49 Used as PCI Subsystem ID for existing hardware devices emulated 50 by QEMU. 51 521af4:1110 53 ivshmem device (:doc:`ivshmem-spec`) 54 55All other device IDs are reserved. 56 571b36 vendor ID 58-------------- 59 60The 0000 -> 00ff device ID range is used as follows for QEMU-specific 61PCI devices (other than virtio): 62 631b36:0001 64 PCI-PCI bridge 651b36:0002 66 PCI serial port (16550A) adapter (:doc:`pci-serial`) 671b36:0003 68 PCI Dual-port 16550A adapter (:doc:`pci-serial`) 691b36:0004 70 PCI Quad-port 16550A adapter (:doc:`pci-serial`) 711b36:0005 72 PCI test device (:doc:`pci-testdev`) 731b36:0006 74 PCI Rocker Ethernet switch device 751b36:0007 76 PCI SD Card Host Controller Interface (SDHCI) 771b36:0008 78 PCIe host bridge 791b36:0009 80 PCI Expander Bridge (``-device pxb``) 811b36:000a 82 PCI-PCI bridge (multiseat) 831b36:000b 84 PCIe Expander Bridge (``-device pxb-pcie``) 851b36:000c 86 PCIe Root Port (``-device pcie-root-port``) 871b36:000d 88 PCI xhci usb host adapter 891b36:000e 90 PCIe-to-PCI bridge (``-device pcie-pci-bridge``) 911b36:000f 92 mdpy (mdev sample device), ``linux/samples/vfio-mdev/mdpy.c`` 931b36:0010 94 PCIe NVMe device (``-device nvme``) 951b36:0011 96 PCI PVPanic device (``-device pvpanic-pci``) 971b36:0012 98 PCI ACPI ERST device (``-device acpi-erst``) 991b36:0013 100 PCI UFS device (``-device ufs``) 101 102All these devices are documented in :doc:`index`. 103 104The 0100 device ID is used for the QXL video card device. 105
