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 (Device Specification for Inter-VM shared memory device)

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 (QEMU PCI serial devices)
1b36:0003: PCI Dual-port 16550A adapter (QEMU PCI serial devices)
1b36:0004: PCI Quad-port 16550A adapter (QEMU PCI serial devices)
1b36:0005: PCI test device (QEMU PCI test device)
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)
1b36:000c: PCIe Root Port (-device pcie-root-port)
1b36:000d: PCI xhci usb host adapter
1b36:000e: PCIe-to-PCI bridge (-device pcie-pci-bridge)
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)
1b36:0014: PCI RISC-V IOMMU device

All these devices are documented in System Emulation Guest Hardware Specifications.

The 0100 device ID is used for the QXL video card device.
