how so? The libpfm4 event names are more or less the same as that from the manuals with the exception that . is replaced with : in some cases. > I'm probably biased, but it's usually best to use the format the CPU > vendor releases the original event tables in.

Unless you mean the tables that come with Vtune... are those licensed in a way that is useful? libpfm4 also provides at least minimal event descriptions along with each event, will the kernel/perf provide those too?
