menuconfig NVM
bool "Open-Channel SSD target support (DEPRECATED)"
depends on BLOCK
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.
This code is deprecated and will be removed in Linux 5.15.
if NVM
config NVM_PBLK
tristate "Physical Block Device Open-Channel SSD target"
select CRC32
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.
if NVM_PBLK
config NVM_PBLK_DEBUG
bool "PBlk Debug Support"
default n
help
Enables debug support for pblk. This includes extra checks, more
vocal error messages, and extra tracking fields in the pblk sysfs
entries.
