I certainly plan to investigate adding pid filtering to the PMU. It is supposed to be possible but I haven't tried it yet. Also not sure if it will be exactly suitable for a top like tool. Will see if I manage to have it working. But what do you say about the simple per-context API (patch 13)? Do you find using ctx get param for this acceptable or you can think of a different way?
