nvme-get-property(1)

SYNOPSIS

nvme get-property <device> [--offset=<offset> | -o <offset>]
                                [--human-readable | -H ]

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

-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

The following will run the get-property command with offset 0
```
# nvme get-property /dev/nvme0 --offset=0x0 --human-readable
```

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
```
