NAME

6       nvme-show-regs - Reads and shows the defined NVMe controller registers
7       for NVMe over PCIe or the controller properties for NVMe over Fabrics.
8

SYNOPSIS

10       nvme show-regs <device> [--human-readable | -H]
11

DESCRIPTION

13       For the NVMe over PCIe device given, sends an identify namespace
14       command and provides the result and returned structure. For the NVMe
15       over Fabrics device given, sends a fabric command and provides the
16       result and returned structure.
17
18       The <device> parameter is mandatory and must be the nvme admin
19       character device (ex: /dev/nvme0). For NVMe over PCIe, the program uses
20       knowledge of the sysfs layout to map the device to the pci resource
21       stored there and mmaps the memory to get access to the registers. For
22       NVMe over Fabrics, the programs sends a fabric command to get the
23       properties of the target NVMe controller. Only the supported properties
24       are displayed.
25

OPTIONS

27       -H, --human-readable
28           Display registers or supported properties in human readable format.
29

EXAMPLES

31       ·   Show the NVMe over PCIe controller registers or the NVMe over
32           Fabric controller properties in a binary format:
33
34               # nvme show-regs /dev/nvme0
35
36       ·   Show the NVMe over PCIe controller registers or the NVMe over
37           Fabric controller properties in a human readable format:
38
39               # nvme show-regs /dev/nvme0 -H
