NVME-GET-PROPERTY(1)		   NVMe Manual		    NVME-GET-PROPERTY(1)

NAME
     nvme-get-property	-  Reads  and shows the defined NVMe controller property
     for NVMe over Fabric

SYNOPSIS
     nvme get-property <device> [--offset=<offset> | -O <offset>]
			     [--human-readable | -H]
			     [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
			     [--timeout=<timeout> | -t <timeout>]

DESCRIPTION
     Reads and shows the defined NVMe controller property for NVMe over Fabric.

OPTIONS
     -O <offset>, --offset=<offset>
	 The offset of the property. One of CAP=0x0, VS=0x8, CC=0x14, CSTS=0x1c,
	 NSSR=0x20

     -H
	 --human-readable: Show the fields packed in the property

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

     -v, --verbose
	 Increase the information detail in the output.

     -t <timeout>, --timeout=<timeout>
	 Override default timeout value. In milliseconds.

EXAMPLES
     *	 The following will run the get-property command with offset 0

	     # nvme get-property /dev/nvme0 --offset=0x0 --human-readable

BUGS
     Currently	the CAP value is truncated to 32 bits due to a limitation in the
     ioctl interface.

     In a recent enough kernel, the 64 bit value is shown in kernel traces.

     *	 First enable traces by this command

	     # echo 1 > /sys/kernel/debug/tracing/events/nvme/enable

     *	 Then look for NVMe Fabrics command (0x7f) at trace

	     /sys/kernel/debug/tracing/trace

NVME
     Part of the nvme-user suite
