This review evaluates the official Unisoc drivers (Linux Kernel 4.14), the Mali GPU driver, ISP (camera) drivers, modem (baseband) RIL, and the state of mainline/Linux community support.
Before we discuss drivers, let’s set the baseline. The UMS9117 is a 28nm quad-core ARM Cortex-A7 processor clocked at 1.3GHz, paired with a Mali-T820 MP1 GPU. It supports up to 3GB of LPDDR3 RAM and runs on 32-bit ARMv7 architecture. While not a powerhouse, its efficiency and low cost have made it a staple. unisoc ums9117 driver better
The Mali GPU driver is a prime candidate for improvement. You can manually inject newer .so (shared object) files: This review evaluates the official Unisoc drivers (Linux
