  8. Say Y here to get to enable Open-channel SSDs.
  9. Open-Channel SSDs implement a set of extension to SSDs, that
  10. exposes direct access to the underlying non-volatile memory.
  11. If you say N, all options in this submenu will be skipped and disabled

  24. Non-volatile memory media manager for Open-Channel SSDs that implements
  25. physical media metadata management and block provisioning API.
  26. This is the standard media manager for using Open-Channel SSDs, and
  27. required for targets to be instantiated.

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