NVD(4)							   BSD Kernel Interfaces Manual 						    NVD(4)

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 kernel disk storage API. It depends on the nvme(4) driver for notifica- tion 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 partitioned. 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 <>, with contributions from Joe Golio at EMC. This man page was written by Jim Harris <>. BSD

geom_uzip -- GEOM based compressed disk images SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: options GEOM_UZIP Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): geom_uzip_load="YES" DESCRIPTION
The geom_uzip framework provides support for compressed read only disk images. This allows significant storage savings at the expense of a little CPU time on each read. Data written in the GEOM label area allows geom_uzip to detect compressed images which have been created with mkuzip(8) and presented to the kernel as a logical disk device via md(4). geom_uzip creates a unique md#.uzip device for each image. The geom_uzip device is subsequently used by the FreeBSD kernel to access the disk images. The geom_uzip driver does not allow write opera- tions to the underlying disk image. To check which md(4) devices match a given geom_uzip device: # geom uzip list Geom name: md1.uzip Providers: 1. Name: md1.uzip Mediasize: 22003712 (21M) Sectorsize: 512 Mode: r1w0e1 Consumers: 1. Name: md1 Mediasize: 9563648 (9.1M) Sectorsize: 512 Mode: r1w0e1 SEE ALSO
