![]() This allows us to 'nest' firmware formats, and removes a ton of duplication. The aim here is to deprecate FuFirmwareImage -- it's almost always acting as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow custom types. If I'm struggling to work out what should be a FuFirmware and what should be a FuFirmwareImage then a plugin author has no hope. For simple payloads we were adding bytes into an image and then the image into a firmware. This gets really messy when most plugins are treating the FuFirmware *as* the binary firmware file. The GBytes saved in the FuFirmware would be considered the payload with the aim of not using FuFirmwareImage in the single-image case. |

ATA
Introduction
This plugin allows updating ATA/ATAPI storage hardware. Devices are enumerated from the block devices and if ID_ATA_DOWNLOAD_MICROCODE is supported they can be updated with appropriate firmware file.
Updating ATA devices is more dangerous than other hardware such as DFU or NVMe and should be tested carefully with the help of the drive vendor.
The device GUID is read 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.t13.ata
GUID Generation
These device use the Microsoft DeviceInstanceId values, e.g.
IDE\VENDOR[40]REVISION[8]
IDE\0VENDOR[40]
See https://docs.microsoft.com/en-us/windows-hardware/drivers/install/identifiers-for-ide-devices for more details.
Update Behavior
The firmware is deployed when the device is in normal runtime mode, but it is only activated when the system is in the final shutdown stages. This is done to minimize the chance of data loss if the switch to the new firmware is not done correctly.
Vendor ID Security
No vendor ID is set as there is no vendor field in the IDENTIFY response.
Quirk use
This plugin uses the following plugin-specific quirks:
Quirk | Description | Minimum fwupd version |
---|---|---|
AtaTransferBlocks |
Blocks to transfer, or 0xffff for max |
1.2.4 |
AtaTransferMode |
The transfer mode, 0x3 , 0x7 or 0xe |
1.2.4 |
External interface access
This plugin requires the SG_IO
ioctl interface.
