NVD(4) FreeBSD Kernel Interfaces Manual NVD(4) NAME nvd -- NVM Express disk driver SYNOPSIS To compile this driver into your kernel, place the following lines in your kernel configuration file: device nvme device nvd Or, to load the driver as a module at boot, place the following lines in loader.conf(5): nvme_load="YES" nvd_load="YES" DESCRIPTION The nvd driver exposes NVM Express (NVMe) namespaces as disks to the ker- nel disk storage API. It depends on the nvme(4) driver for notification of existing NVMe namespaces and submission of NVM I/O commands. Device nodes from the nvd driver will have the format /dev/nvdX and are GEOM(4) disks which can be partitioned by geom(8). Note that device nodes from the nvme(4) driver are not GEOM(4) disks and cannot be parti- tioned. CONFIGURATION The nvd driver defines a system-wide maximum delete size for NVMe devices. The default is 1GB. To select a different value, set the fol- lowing tunable in loader.conf(5): hw.nvd.delete_max=<delete size in bytes> SEE ALSO GEOM(4), nvme(4), geom(8), nvmecontrol(8), disk(9) HISTORY The nvd driver first appeared in FreeBSD 9.2. AUTHORS The nvd driver was developed by Intel and originally written by Jim Harris <jimharris@FreeBSD.org>, with contributions from Joe Golio at EMC. This man page was written by Jim Harris <jimharris@FreeBSD.org>. FreeBSD 11.1 January 28, 2016 FreeBSD 11.1
