1config NVME_CORE 2 tristate 3 4config BLK_DEV_NVME 5 tristate "NVM Express block device" 6 depends on PCI && BLOCK 7 select NVME_CORE 8 ---help--- 9 The NVM Express driver is for solid state drives directly 10 connected to the PCI or PCI Express bus. If you know you 11 don't have one of these, it is safe to answer N. 12 13 To compile this driver as a module, choose M here: the 14 module will be called nvme. 15 16config BLK_DEV_NVME_SCSI 17 bool "SCSI emulation for NVMe device nodes" 18 depends on NVME_CORE 19 ---help--- 20 This adds support for the SG_IO ioctl on the NVMe character 21 and block devices nodes, as well as a translation for a small 22 number of selected SCSI commands to NVMe commands to the NVMe 23 driver. If you don't know what this means you probably want 24 to say N here, unless you run a distro that abuses the SCSI 25 emulation to provide stable device names for mount by id, like 26 some OpenSuSE and SLES versions. 27 28config NVME_FABRICS 29 tristate 30 31config NVME_RDMA 32 tristate "NVM Express over Fabrics RDMA host driver" 33 depends on INFINIBAND 34 depends on BLK_DEV_NVME 35 select NVME_FABRICS 36 select SG_POOL 37 help 38 This provides support for the NVMe over Fabrics protocol using 39 the RDMA (Infiniband, RoCE, iWarp) transport. This allows you 40 to use remote block devices exported using the NVMe protocol set. 41 42 To configure a NVMe over Fabrics controller use the nvme-cli tool 43 from https://github.com/linux-nvme/nvme-cli. 44 45 If unsure, say N. 46
