DESCRIPTION
|
||
|
|
-----------

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
|
||
|
|
--------
|
||

|
||
|
|

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
