# libfprint Goodix SPI Driver: reconstructing GDIX51C0 support

> libfprint Goodix SPI Driver reconstructs support for the Goodix GDIX51C0 fingerprint sensor on Linux. It combines SPI transport, session and capture handling with a native ChicagoHS host-side biometric matcher, integrated through libfprint and fprintd patches. The source includes protocol research, algorithm comparison tools and deterministic tests.

## Requirements & limits

- **Prerequisites:** Requires a GDIX51C0 sensor exposed through Linux spidev; the documented defaults were hardware-tested on a Huawei MateBook 16s.
- **Prerequisites:** Integration targets libfprint v1.94.10 and fprintd v1.94.5, with the listed build dependencies.
- **Limits:** This is a pre-release; other laptops may need GPIO overrides.
- **License:** Original project source is LGPL-2.1-or-later; adapted files and patches retain their stated upstream licenses.
