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. |

Focal TouchPad
Introduction
This plugin allows updating Touchpad devices from Focal. Devices are enumerated using HID . The I²C mode is used for firmware recovery.
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:
- tw.com.focalfp
GUID Generation
These device uses the standard DeviceInstanceId values, e.g.
HIDRAW\VEN_2808&DEV_0106
Update Behavior
The device usually presents in HID mode, and the firmware is written to the device by switching to a IAP mode where the touchpad is nonfunctional. Once complete the device is reset to get out of IAP mode and to load the new firmware version.
On flash failure the device is nonfunctional, but is recoverable by writing to the i2c device. This is typically much slower than updating the device using HID and also requires a model-specific HWID quirk to match.
Vendor ID Security
The vendor ID is set from the HID vendor, for example set to HIDRAW:0x17EF
Quirk Use
This plugin uses the following plugin-specific quirks:
External Interface Access
This plugin requires ioctl access to HIDIOCSFEATURE and HIDIOCGFEATURE.
