NAME

       nvme-show-regs - Reads and shows the defined NVMe controller registers for NVMe over PCIe
       or the controller properties for NVMe over Fabrics.

SYNOPSIS

       nvme show-regs <device>       [--human-readable | -H]
                                       [--output-format=<FMT> | -o <FMT>]

DESCRIPTION

       For the NVMe over PCIe device given, sends an identify namespace command and provides the
       result and returned structure. For the NVMe over Fabrics device given, sends a fabric
       command and provides the result and returned structure.

       The <device> parameter is mandatory and must be the nvme admin character device (ex:
       /dev/nvme0). For NVMe over PCIe, the program uses knowledge of the sysfs layout to map the
       device to the pci resource stored there and mmaps the memory to get access to the
       registers. For NVMe over Fabrics, the programs sends a fabric command to get the
       properties of the target NVMe controller. Only the supported properties are displayed.

OPTIONS

       -H, --human-readable
           Display registers or supported properties in human readable format.

       -o <format>, --output-format=<format>
           Set the reporting format to normal, json, or binary. Only one output format can be
           used at a time.

EXAMPLES

       •   Show the NVMe over PCIe controller registers or the NVMe over Fabric controller
           properties in a binary format:

               # nvme show-regs /dev/nvme0 -o binary

       •   Show the NVMe over PCIe controller registers or the NVMe over Fabric controller
           properties in a human readable format:

               # nvme show-regs /dev/nvme0 -H

       •   Show the NVMe over PCIe controller registers or NVMe-oF controller properties in a
           json format:

               # nvme show-regs /dev/nvme0 -o json
