   1 config BLK_DEV_NVME

   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.

   9           To compile this driver as a module, choose M here: the
  10           module will be called nvme.

  12 config 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.
