i'm trying to analyze netfiltering and routing workload inside the kernel for PowerPC(a typical kernel 'application', and I can not figure out how to do the workload analysis in use space for them), is there a way to trace all the instruction flow(e.g. a packet coming-in--> going-out) so I can use the result to further analyze things like cache hit/miss, latency,drop rate,etc? I'd like to collect the raw instruction flow in simulation state(non realtime). LTT(Linux Trace Toolkit) is a good tool, but I want more detailing tracing info. I tried UML, it doesn't work well on PowerPC so far. Is it possible at all? Thanks __________________________________________________ Do You Yahoo!? Yahoo!
