The NVMe over Fabrics library provides an interface for both transports and the nvme core to handle fabrics specific commands and attributes independent of the underlying transport. In addition, the fabrics library adds a misc device interface that allow actually creating a fabrics controller, as we can't just autodiscover it like in the PCI case. The nvme-cli utility has been enhanced to use this interface to support fabric connect and discovery.

The NVM Express driver is for solid state drives directly
|
|
connected to the PCI or PCI Express bus. If you know you
|
|
don't have one of these, it is safe to answer N.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called nvme.

bool "SCSI emulation for NVMe device nodes"
|

depends on NVME_CORE
|
|
---help---
|
|
This adds support for the SG_IO ioctl on the NVMe character
|
|
and block devices nodes, as well as a translation for a small
|
|
number of selected SCSI commands to NVMe commands to the NVMe
|
|
driver. If you don't know what this means you probably want
|
|
to say N here, unless you run a distro that abuses the SCSI
|
|
emulation to provide stable device names for mount by id, like
|
|
some OpenSuSE and SLES versions.
