With open source GPU drivers coming to ARM in the last few years, we have mesa and therefore desktop OpenGL available on some ARM based platforms: https://nullr0ute.com/2017/09/the-state-of-open-source-accelerated-graphics-on-arm-devices/ Only PowerVR and Mali are still stuck with proprietary drivers at this point, sadly they are a large part of the market. > So I guess anything that uses GL stuff outside the ES API won't > actually work on 32-bits arm anyway so there is not much point > building it there. > > But my understanding of the graphics stack is weak so I could well be > out-of-date or otherwise confused. -- bye, pabs https://wiki.debian.org/PaulWise
