Is there any information about how to use the QPUs, and how can I be of help? I own two raspberry pis, one of them is idle at the moment. I'm developing a vc4 backend for GCC at https://github.com/felipealmeida/gcc-vc4 which already generates vc4 assembly for a few insns (and crashes the compiler for other more complex code right now). It must be compiled with GNU as from the binutils vc4 port. Regards, -- Felipe Magno de Almeida
