I have been thinking of the ARMv7 / SMP infrastructure. http://www.tinguelys.info/mark/freebsd/v7Roadmap.txt Disclaimer: recently, I am less sure that all ARMv6 cores can do TEX remap. 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.
