FPU and MAU are treated differently, FPUs are not 'owned' by threads or LDOMs the FPU is simply passed instructions from either of the two execution cores that are seeing FP instructions, but MAU's are tied to threads and therefore tied to LDOMs, only the LDOMS that own the threads via which their exclusive access to the MAU is provided can put work packets onto the MAU.
