NAME
nda — NVMe Direct Access device driver
SYNOPSIS
device nvme
device scbus
DESCRIPTION
The nda driver provides support for direct access devices, implementing
the NVMe command protocol, that are attached to the system through a host
adapter supported by the CAM subsystem.
SYSCTL VARIABLES
The following variables are available as both sysctl(8) variables and
loader(8) tunables:
kern.cam.nda.sort_io_queue
This variable determines whether the software queued entries are
sorted in LBA order or not. Sorting is almost always a waste of
time. The default is to not sort.
The following report per-device settings, and are read-only unless other‐
wise indicated. Replace N with the device unit number.
kern.cam.nda.N.rotating
This variable reports whether the storage volume is spinning or
flash. It's value is hard coded to 0 indicating flash.
kern.cam.nda.N.unmapped_io
This variable reports whether the nda driver accepts unmapped I/O for
this unit.
