Convert pci-serial.txt to reStructuredText. This includes
some wordsmithing, and the correction of the docs to note
that the Windows inf file includes 2x and 4x support
(as it has done since commit dc9528fdf9 in 2014).

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 is 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 to 1af4:10ef
|
|
ID range for modern virtio devices. The PCI device
|
|
ID is calculated from the virtio device ID by adding the
|
|
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 to 1a4f:10ff
|
|
Available for experimental usage without registration. Must get
|
|
official ID when the code leaves the test lab (i.e. when seeking
|
|
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 (:doc:`pci-serial`)
|
|
1b36:0003
|
|
PCI Dual-port 16550A adapter (:doc:`pci-serial`)
|
|
1b36:0004
|
|
PCI Quad-port 16550A adapter (:doc:`pci-serial`)
|
|
1b36:0005
|
|
PCI test device (``docs/specs/pci-testdev.txt``)
|
|
1b36:0006
|
|
PCI Rocker Ethernet switch device
|
|
1b36:0007
|
|

|
|
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 :doc:`index`.
|
|
|
|
The 0100 device ID is used for the QXL video card device.
