Technically feasible. But then we would have to parse each of the

You could do it at 'perf list' time or even build time and cache it. And add lazy discovery to 'perf record' and friends.

Instead searching all the known files or building a cache, how about just having an option like: perf list <DSO>. perf-record could still do the probe magic behind the scenes.
