Do not mix GPU (3d acceleration/OpenGLES with ARM proprietary and closed sourced "mali450mp2" HW) and VPU (video decoding/encoding acceleration that is Rockchip proprietary but open sourced in user space (MPP) and kernel space "rkdec"/"rkvdec"/"rkvenc"/"vpu"/"vpu-service"/"avsd"/"vepu"/"h265e" HW) !
Opensource GPU drivers are developed under name Lima.
Check wiki rk3328, wiki MPP, wiki.

I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" 
. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
