| Say Y here to get to enable Open-channel SSDs. |
| |
| Open-Channel SSDs implement a set of extension to SSDs, that |
| exposes direct access to the underlying non-volatile memory. |

| If you say N, all options in this submenu will be skipped and disabled |
| only do this if you know what you are doing. |

| bool "Open-Channel SSD debugging support" |

| ---help--- |
| Exposes a debug management interface to create/remove targets at: |
| |
| /sys/module/lnvm/parameters/configure_debug |
| |
| It is required to create/remove targets without IOCTLs. |

| config NVM_RRPC |
| tristate "Round-robin Hybrid Open-Channel SSD target" |
| ---help--- |
| Allows an open-channel SSD to be exposed as a block device to the |
| host. The target is implemented using a linear mapping table and |
| cost-based garbage collection. It is optimized for 4K IO sizes. |
| |
| config NVM_PBLK |
| tristate "Physical Block Device Open-Channel SSD target" |
| ---help--- |
| Allows an open-channel SSD to be exposed as a block device to the |
| host. The target assumes the device exposes raw flash and must be |
| explicitly managed by the host. |
| |
| Please note the disk format is considered EXPERIMENTAL for now. |
