| 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 | |
| 4ea9296c | 6 | virtual devices. The vendor IDs are 1af4 (formerly Qumranet ID) and 1b36. |

8 | Contact Gerd Hoffmann <kraxel@redhat.com> to get a device ID assigned |
| 9 | for your devices. | |

14 | The 1000 -> 10ff device ID range is used as follows for virtio-pci devices. |
| 15 | Note that this allocation separate from the virtio device IDs, which are | |
| 16 | maintained as part of the virtio specification. | |

| 27 | 1af4:1040 Start of ID range for modern virtio devices. The PCI device | |
| 28 | to ID is calculated from the virtio device ID by adding the | |
| 29 | 1af4:10ef 0x1040 offset. The virtio IDs are defined in the virtio | |
| 30 | specification. The Linux kernel has a header file with | |
| 31 | defines for all virtio IDs (linux/virtio_ids.h), qemu has a | |
| 32 | copy in include/standard-headers/. | |

| 34 | 1af4:10f0 Available for experimental usage without registration. Must get | |
| 35 | to official ID when the code leaves the test lab (i.e. when seeking | |
| 36 | 1af4:10ff upstream merge or shipping a distro/product) to avoid conflicts. | |
