Right, this so far is as ad-hoc as it can be :-) One idea that is in my TODO list is to generate some XML format people say that oprofile produces and there is also some other format that a valgrind tool uses that should be supported. I also plan to have it in a spreadsheet TUI widget, allowing lots of navigation gimmicks to help in debugging, like a popup that offers the list of mmaps for the thread where the sample below the cursor happened, etc. - Arnaldo ------------------------------------------------------------------------------ _______________________________________________ perfmon2-devel mailing list perfmon2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/perfmon2-devel
