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 NVME_MULTIPATH bool "NVMe multipath support" depends on NVME_CORE ---help--- This option enables support for multipath access to NVMe subsystems. If this option is enabled only a single /dev/nvmeXnY device will show up for each NVMe namespaces, even if it is accessible through multiple controllers. config NVME_FABRICS tristate config NVME_RDMA tristate "NVM Express over Fabrics RDMA host driver" depends on INFINIBAND && INFINIBAND_ADDR_TRANS && BLOCK 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. config NVME_FC tristate "NVM Express over Fabrics FC host driver" depends on BLOCK depends on HAS_DMA select NVME_CORE select NVME_FABRICS select SG_POOL help This provides support for the NVMe over Fabrics protocol using the FC 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.
