To really take advantage of the new ARM features, we need a newer compiler. I have an old hacked up early gcc 4.5 snapshot, but it does not compile itself. clang does not cross compile and I have not tried to compile it under ARM. Does the OMAP4 implement the MP extensions? They would simply the SMP coherency/TLB operations by not having to perform an IPI. --Mark.
