Make sure to add the kernel
NVM Express block device (BLK_DEV_NVME) CONFIG_BLK_DEV_NVME: 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. Symbol: BLK_DEV_NVME [=m] Type : tristate Prompt: NVM Express block device Location: -> Device Drivers Defined at drivers/nvme/host/Kconfig:1 Depends on: PCI [=y] && BLOCK [=y]
