My patchset does not cover the general PEBS case (not LL). However, I think we can leverage the machine state captured by PEBS by adding a simple patch on top of Jiri's sample regs patchset. I have experimented with that last week. One interesting measurement you can make on SNB once you have that is : value profiling. That means sampling the values of function arguments. I think we can fit this into perf report.
My problem with the script approach is that you may end up re-inventing a lot of the infrastructure already in perf in terms of histograming and sorting. I think scripts are good for dumping the raw data or very simply analysis. Now I recognize that they are handy to implement mahcine specific decoding of the samples.
