+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
+1af4:1001  block device
+1af4:1002  balloon device
+1af4:1003  console device
+1af4:1004  SCSI host bus adapter device
+1af4:1005  entropy generator device
+1af4:1009  9p filesystem device
+
+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_device_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)
+
+All these devices are documented in docs/specs.
+
+The 0100 device ID is used for the QXL video card device.

-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 ID is 1af4 (formerly Qumranet ID).
-
-The 1000 -> 10ff device ID range is used for VirtIO devices.
-
-The 1100 device ID is used as PCI Subsystem ID for existing hardware
-devices emulated by qemu.
-
-All other device IDs are reserved.
-
-
-VirtIO Device IDs
------------------
-
-1af4:1000  network device
-1af4:1001  block device
-1af4:1002  balloon device
-1af4:1003  console device
-
-1af4:1004  Reserved.
-   to      Contact Gerd Hoffmann <kraxel@redhat.com> to get a
-1af4:10ef  device ID assigned for your new virtio device.
-
-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.
