It's actually quite hard to build a front-end for fwupd at the moment as you're never sure when the progress bar is going to zip back to 0% and start all over again. Some plugins go 0..100% for write, others go 0..100% for erase, then again for write, then *again* for verify. By creating a helper object we can easily split up the progress of the specific task, e.g. write_firmware(). We can encode at the plugin level "the erase takes 50% of the time, the write takes 40% and the read takes 10%". This means we can have a progressbar which goes up just once at a consistent speed. |

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:
AtaTransferBlocks
Blocks to transfer, or 0xffff for max
Since: 1.2.4
AtaTransferMode
The transfer mode, 0x3, 0x7 or 0xe
Since: 1.2.4
External Interface Access
This plugin requires the SG_IO ioctl interface.
