.Sh NAME
|
|
.Nm nvd
|
|
.Nd NVM Express disk driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into your kernel,
|
|
place the following lines in your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device nvme"
|
|
.Cd "device nvd"
|
|
.Ed
|
|
.Pp
|
|
Or, to load the driver as a module at boot, place the following lines in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
nvme_load="YES"
|
|
nvd_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver exposes NVM Express (NVMe) namespaces as disks to the kernel disk
|
|
storage API.
|
|
It depends on the
|
|
.Xr nvme 4
|
|
driver for notification of existing NVMe namespaces and submission of NVM
|
|
I/O commands.
|
|
.Pp
|
|
Device nodes from the
|
|
.Nm
|
|
driver will have the format /dev/nvdX and are
|
|
.Xr GEOM 4
|
|
disks which can be partitioned by
|
|
.Xr geom 8 .
|
|
Note that device nodes from the
|
|
.Xr nvme 4
|
|
driver are not
|
|
.Xr GEOM 4
|
|
disks and cannot be partitioned.
