I am not sure what that means. If it's wanting to get a trace of all
kernel instructions, then it may be useful to look at the IBM itrace
system. Considering the huge performance penalty that per-instruction
tracing is bound to cause, it may be worthwhile to run your whole
kernel under a simulator, and instrument that rather than the kernel
running underneath.
