2 # Open-Channel SSD NVM configuration
6 bool "Open-Channel SSD target support"
7 depends on BLOCK && HAS_DMA && PCI
10 Say Y here to get to enable Open-channel SSDs.
12 Open-Channel SSDs implement a set of extension to SSDs, that
13 exposes direct access to the underlying non-volatile memory.
15 If you say N, all options in this submenu will be skipped and disabled
16 only do this if you know what you are doing.
21 bool "Open-Channel SSD debugging support"
24 Exposes a debug management interface to create/remove targets at:
26 /sys/module/lnvm/parameters/configure_debug
28 It is required to create/remove targets without IOCTLs.
31 tristate "Round-robin Hybrid Open-Channel SSD target"
33 Allows an open-channel SSD to be exposed as a block device to the
34 host. The target is implemented using a linear mapping table and
35 cost-based garbage collection. It is optimized for 4K IO sizes.
38 tristate "Physical Block Device Open-Channel SSD target"
40 Allows an open-channel SSD to be exposed as a block device to the
41 host. The target assumes the device exposes raw flash and must be
42 explicitly managed by the host.
44 Please note the disk format is considered EXPERIMENTAL for now.
