tristate "NVM Express block device"
depends on PCI && BLOCK
select NVME_CORE
---help---
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.
config BLK_DEV_NVME_SCSI
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.

tristate "NVM Express over Fabrics RDMA host driver"
depends on INFINIBAND
select NVME_CORE
select NVME_FABRICS
select SG_POOL
help
This provides support for the NVMe over Fabrics protocol using
the RDMA (Infiniband, RoCE, iWarp) transport. This allows you
to use remote block devices exported using the NVMe protocol set.
To configure a NVMe over Fabrics controller use the nvme-cli tool
from https://github.com/linux-nvme/nvme-cli.
If unsure, say N.
