11 Open-Channel SSDs implement a set of extension to SSDs, that
12 exposes direct access to the underlying non-volatile memory.

31 ---help---
32 Allows an open-channel SSD to be exposed as a block device to the
33 host. The target is implemented using a linear mapping table and
34 cost-based garbage collection. It is optimized for 4K IO sizes.

36config NVM_PBLK
37 tristate "Physical Block Device Open-Channel SSD target"
38 ---help---
39 Allows an open-channel SSD to be exposed as a block device to the
40 host. The target assumes the device exposes raw flash and must be
41 explicitly managed by the host.

43 Please note the disk format is considered EXPERIMENTAL for now.
