# # 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_GENNVM tristate "General Non-Volatile Memory Manager for Open-Channel SSDs" ---help--- Non-volatile memory media manager for Open-Channel SSDs that implements physical media metadata management and block provisioning API. This is the standard media manager for using Open-Channel SSDs, and required for targets to be instantiated. 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. endif # NVM
