# Open-Channel SSD NVM configuration
#
menuconfig NVM
bool "Open-Channel SSD target support"
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.
if NVM
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.
