- depends on BLOCK && HAS_DMA
- help
- 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.

- config NVM_DEBUG
- bool "Open-Channel SSD debugging support"
- default n
- ---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.
