| 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. |
| |
| 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) |
| 1af4:1002 |
| balloon device (legacy) |
| 1af4:1003 |
| console device (legacy) |
| 1af4:1004 |
| SCSI host bus adapter device (legacy) |
| 1af4:1005 |
| entropy generator device (legacy) |
| 1af4:1009 |
| 9p filesystem device (legacy) |
| 1af4:1012 |
| vsock device (bug compatibility) |
| |
| 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``) |
| |
| All other device IDs are reserved. |
| |
| 1b36 vendor ID |
| -------------- |
| |
| The 0000 -> 00ff device ID range is used as follows for QEMU-specific |
| PCI devices (other than virtio): |
| |
| 1b36:0001 |
| PCI-PCI bridge |
| 1b36:0002 |
| PCI serial port (16550A) adapter (:doc:`pci-serial`) |
| 1b36:0003 |
| PCI Dual-port 16550A adapter (:doc:`pci-serial`) |
| 1b36:0004 |
| PCI Quad-port 16550A adapter (:doc:`pci-serial`) |
| 1b36:0005 |
| PCI test device (:doc:`pci-testdev`) |
| 1b36:0006 |
| PCI Rocker Ethernet switch device |
| 1b36:0007 |
| PCI SD Card Host Controller Interface (SDHCI) |
| 1b36:0008 |
| PCIe host bridge |
| 1b36:0009 |
| PCI Expander Bridge (-device pxb) |
| 1b36:000a |
| PCI-PCI bridge (multiseat) |
| 1b36:000b |
| PCIe Expander Bridge (-device pxb-pcie) |
| 1b36:000d |
| PCI xhci usb host adapter |
| 1b36:000f |
| mdpy (mdev sample device), ``linux/samples/vfio-mdev/mdpy.c`` |
| 1b36:0010 |
| PCIe NVMe device (``-device nvme``) |
| 1b36:0011 |
| PCI PVPanic device (``-device pvpanic-pci``) |
| 1b36:0012 |
| PCI ACPI ERST device (``-device acpi-erst``) |
| 1b36:0013 |
| PCI UFS device (``-device ufs``) |
| |
| All these devices are documented in :doc:`index`. |
| |
| The 0100 device ID is used for the QXL video card device. |
