That would be very useful indeed.. I think we talked about this before. Also
wasn't there some vendor support for this idea as well?

I think we want a format that is relatively simple to parse and human readable
(which excludes XML on both counts ;-).

The main objection of using libpfm4 has always been that its primarily
something else.  It also does the event listing thing, but that's only a small
part of it.

But if we can split out that part and use it in both projects that would be
best I think.
