We have a lurking bug where Fragment Shader Helper Invocations can't load from memory. But this is actually required in OpenGL and is causing random hangs or failures in random shaders. It is unknown how widespread this issue is, but shaders hitting this can end up with infinite loops. We enable those only on all Kepler and newer GPUs where we use our own Firmware. Nvidia's firmware provides a way to set a kernelspace controlled list of mmio registers in the gr space from push buffers via MME macros. v2: drop code for gm200 and newer.
