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.

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.

---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.
