   2 PCI IDs for QEMU
   3 ================

   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.

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

  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):
  62
