Introduction

This plugin allows updating Touchpad devices from Goodix. Devices are enumerated using HID and raw I²C nodes. The I²C mode is used for ABS devices and firmware recovery of HID devices.

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:

• com.goodix.goodixtp

GUID Generation

These device uses the standard DeviceInstanceId values, e.g.

• HIDRAW\VEN_27C6&DEV_1234

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

Vendor ID Security

The vendor ID is set from the HID vendor, for example set to HIDRAW:0x01E0

External Interface Access

This plugin requires ioctl access to HIDIOCSFEATURE and HIDIOCGFEATURE.

Version Considerations

This plugin has been available since fwupd version 1.9.2.
