NVMe

Introduction

This plugin adds support for NVMe storage hardware. Devices are enumerated from the Identify Controller data structure and can be updated with appropriate firmware file. Firmware is sent in 4kB chunks and activated on next reboot.

The device GUID is read from the vendor specific area and if not found then generated from the trimmed model string.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

GUID Generation

These device use the NVMe DeviceInstanceId values, e.g.

NVME\VEN_1179&DEV_010F&REV_01
NVME\VEN_1179&DEV_010F
NVME\VEN_1179

Additionally, for NVMe drives with Dell vendor firmware two extra GUIDs are added:

STORAGE-DELL-${component-id}

and any optional GUID saved in the vendor extension block.

Quirk use

This plugin uses the following plugin-specific quirks:

Quirk	Description	Minimum fwupd version
`NvmeBlockSize`	The block size used for NVMe writes	1.1.3
