Based on, and with help of, the great work of Graugans I was able to create a Yocto recipe that allows JavaFX to use the Vivante drivers natively, thus enhancing performance of the user interface code greatly. I'm by far not a Yocto expert, but I would still like to share my recipe. You can find it at the Bitbucket repository: https://bitbucket.org/cuhka/meta-cuhka
