Sony Fingerprint HAL (TZ based)

Sony Fingerprint HAL

This is an open android HAL to enable the use for the fingerprint authentication sensor on the sony platforms. It makes use of the TrustZone (TZ) fingerprint application via the QSEECOM API (documented here https://android.googlesource.com/platform/hardware/qcom/keymaster/+/android-6.0.1_r26/QSEEComAPI.h)

Overview

• This was based around the OnePlus Two TrustZone fingerprint HAL (found here https://github.com/CyanogenMod/android_device_oneplus_oneplus2/blob/cm-13.0/fingerprint)
• Extra information was obtained from the Nexus 6P (angler kernel driver) (found here https://android.googlesource.com/kernel/msm/+/3d0a564505ab8452e7e6f52b972db386cc2f5f69)
• Protocol information was verified as it passed through the QSEECOM API to linux kernel

Rebuild and run quickly

$ m android.hardware.biometrics.fingerprint@2.1-service.sony && adb sync && adb shell setprop ctl.restart fps_hal

On devices where adb sync tries to sync too much, in turn running out of inodes, push the binary directly. For PDX213 for example:

$ m android.hardware.biometrics.fingerprint@2.1-service.sony && adb push out/target/product/pdx213/vendor/bin/hw/android.hardware.biometrics.fingerprint@2.1-service.sony vendor/bin/hw && adb shell setprop ctl.restart fps_hal
