config NVME_CORE tristate config BLK_DEV_NVME 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. config NVME_FABRICS tristate config NVME_RDMA 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.
