What happened to the question whether to use PURR values for also measuring cycles spent executing the hcall as opposed to cycles that passed before the hcall returns. Did that turn out not giving extra information after all or was there a different reason to drop that idea?
You have to be careful with PURR since it may be context switched between partitions. Anton
