1config BLK_DEV_NVME 2 tristate "NVM Express block device" 3 depends on PCI && BLOCK 4 ---help--- 5 The NVM Express driver is for solid state drives directly 6 connected to the PCI or PCI Express bus. If you know you 7 don't have one of these, it is safe to answer N. 8 9 To compile this driver as a module, choose M here: the 10 module will be called nvme. 11 12config BLK_DEV_NVME_SCSI 13 bool "SCSI emulation for NVMe device nodes" 14 depends on BLK_DEV_NVME 15 ---help--- 16 This adds support for the SG_IO ioctl on the NVMe character 17 and block devices nodes, as well a a translation for a small 18 number of selected SCSI commands to NVMe commands to the NVMe 19 driver. If you don't know what this means you probably want 20 to say N here, unless you run a distro that abuses the SCSI 21 emulation to provide stable device names for mount by id, like 22 some OpenSuSE and SLES versions. 23
