A Graphics Device Driver Implementation Compliant with OpenGL SC 2.0.1 Standard Specification

Various 3D graphics outputs are increasingly required in the field of safety-critical applications including military, avionics, aerospace, and medical applications. In this paper, we present a graphics device driver implementation of OpenGL SC (Open Graphics Library – Safety Critical) 2.0.1, a 3D graphics standard specification that reflects the needs of the safety-critical field. OpenGL SC 2.0.1 was newly announced in 2019, and only a few limited number of implementation cases have been reported so far. In this paper, to increase its own portability, we designed to only use some functions of DRM (direct rendering manager) in a general Linux environment, while various test results were confirmed targeting specific GPUs, in our case, Intel HD630 GPU. The implementation results can be used to implement 3D graphics terminals in the military and aviation fields.
