![]() In many plugins we've wanted to use ->prepare_firmware() to parse the firmware ahead of ->detach() and ->write_firmware() but this has the limitation that it can only return a single blob of data. For many devices, multiple binary blobs are required from one parsed image, for instance providing signatures, config and data blobs that have to be pushed to the device in different way. This also means we parse the firmware *before* we ask the user to detach. Break the internal FuDevice API to support these firmware types as they become more popular. This also allows us to move the Intel HEX and SREC parsing out of the dfu plugin as they are used by a few plugins now, and resolving symbols between plugins isn't exactly awesome. |

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.
This plugin supports the following protocol ID:
- org.nvmexpress
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
The FRU globally unique identifier (FGUID) is also added from the CNS if set. Please refer to this document for more details on how to add support for FGUID: https://nvmexpress.org/wp-content/uploads/NVM_Express_Revision_1.3.pdf
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 |

The block size used for NVMe writes | 1.1.3 |
Flags |
force-align if image should be padded |
