Jiri,
I don't see part 0/8 of this series. Did you send it to me too?
I have some comments about it. I don't see why create something from scratch when I have been developing a library (libpfm4) that takes care of that and that is already used by many tool developers. That library can be linked with perf and provide full symbolic events + all the modifiers. The library is portable and supports all existing archs. It can also be used by self-monitoring apps.
You're introducing yet another event table to maintain. And believe me this is a lot of work to maintain this.
I don't understand why not use this existing library.
