| 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 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 Start of ID range for modern virtio devices. The PCI device |
| to ID is calculated from the virtio device ID by adding the |
| 1af4:10ef 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 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. |
| |
| 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 (docs/specs/pci-serial.txt) |
| 1b36:0003 PCI Dual-port 16550A adapter (docs/specs/pci-serial.txt) |
| 1b36:0004 PCI Quad-port 16550A adapter (docs/specs/pci-serial.txt) |
| 1b36:0005 PCI test device (docs/specs/pci-testdev.txt) |
| 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) |
| |
| All these devices are documented in docs/specs. |
| |
| The 0100 device ID is used for the QXL video card device. |
