nvme-get-property(1)
====================

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
+

/sys/kernel/debug/tracing/trace
