Universal Flash Storage (UFS) is a high-performance mass storage device with a serial interface. It is primarily used as a high-performance data storage device for embedded applications. This commit contains code for UFS device to be recognized as a UFS PCI device. Patches to handle UFS logical unit and Transfer Request will follow.

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
|
|

|
|
