Richard Hughes c4b7f42e43 Only compress one version of the builtin-quirks
Saving the quirks in the GResource section worked well, but it made the build
system very complicated and also meant the .data section was duplicated in
both `fwupd` and `fwupdtool` -- negating a lot of the hard-fought savings.

Simplify this feature so that we just `cat` all the quirk files together, then
gzip them into a single file. This means that at startup fwupd only needs to
check the mtime of one file, and weirdly it's actually faster to load a smaller
compressed file from disk that it is to load multiple uncompressed files.

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.
