====================

NAME

----

nvme-get-property - Reads and shows the defined NVMe controller property

for NVMe over Fabric

SYNOPSIS

--------

[verse]

'nvme get-property' <device> [--offset=<offset> | -o <offset>]

				[--human-readable | -H ]

DESCRIPTION

-----------

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

OPTIONS

-------

-o::

--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

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

+
