    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.

    Which vendors provide "original tables"? None as far as I know, you are
    stuck digging through PDFs.

    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?
