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]

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.

EXAMPLES

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

               # nvme show-regs /dev/nvme0

       •   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
