docs/specs/pci-ids: Convert from txt to rST
Convert the pci-ids document from plain text to reStructuredText. I opted to use definition-lists here because rST tables are super-clunky, and actually formatting these as tables didn't seem necessary.

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.
|
||||
|
||||

|
||||
network 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``)

1b36 vendor ID
|
||||
--------------
|

The 0000 -> 00ff device ID range is used as follows for QEMU-specific
