| 2 | PCI IDs for QEMU | |
| 3 | ================ | |
| 4 | ||
| 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. | |
| 7 | ||
| 8 | Contact Gerd Hoffmann <kraxel@redhat.com> to get a device ID assigned | |
| 9 | for your devices. | |
| 10 | ||
| 11 | 1af4 vendor ID | |
| 12 | -------------- | |
| 13 | ||
| 14 | The 1000 -> 10ff device ID range is used as follows for virtio-pci devices. | |
| 15 | Note that this allocation is separate from the virtio device IDs, which are | |
| 16 | maintained as part of the virtio specification. | |
| 17 | ||
| 18 | 1af4:1000 | |
| 19 | network device (legacy) | |
| 20 | 1af4:1001 | |
| 21 | block device (legacy) | |
| 22 | 1af4:1002 | |
| 23 | balloon device (legacy) | |
| 24 | 1af4:1003 | |
| 25 | console device (legacy) | |
| 26 | 1af4:1004 | |
| 27 | SCSI host bus adapter device (legacy) | |
| 28 | 1af4:1005 | |
| 29 | entropy generator device (legacy) | |
| 30 | 1af4:1009 | |
| 31 | 9p filesystem device (legacy) | |
| 32 | 1af4:1012 | |
| 33 | vsock device (bug compatibility) | |
| 34 | ||
| 35 | 1af4:1040 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 | ||
| 43 | 1af4:10f0 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 | ||
| 48 | 1af4:1100 | |
| 49 | Used as PCI Subsystem ID for existing hardware devices emulated | |
| 50 | by QEMU. | |
| 51 | ||
| 52 | 1af4:1110 | |
| 53 | ivshmem device (shared memory, ``docs/specs/ivshmem-spec.txt``) | |
| 54 | ||
| 55 | All other device IDs are reserved. | |
| 56 | ||
| 57 | 1b36 vendor ID | |
| 58 | -------------- | |
| 59 | ||
| 60 | The 0000 -> 00ff device ID range is used as follows for QEMU-specific | |
| 61 | PCI devices (other than virtio): | |
