41 .Nd NVM Express disk driver
43 To compile this driver into your kernel,
44 place the following lines in your kernel configuration file:
45 .Bd -ragged -offset indent
50 Or, to load the driver as a module at boot, place the following lines in
52 .Bd -literal -offset indent
59 driver exposes NVM Express (NVMe) namespaces as disks to the kernel disk
63 driver for notification of existing NVMe namespaces and submission of NVM
68 driver will have the format /dev/nvdX and are
70 disks which can be partitioned by
72 Note that device nodes from the
76 disks and cannot be partitioned.
80 driver defines a system-wide maximum delete size for NVMe devices. The
81 default is 1GB. To select a different value, set the following tunable in
83 .Bd -literal -offset indent
84 hw.nvd.delete_max=<delete size in bytes>
