Hi Ted. I would have loved to have fixed it myself, or had one of the other oprofile contributors do so. Unfortunately I have no control over what the distributions do. For example: https://bugzilla.redhat.com/show_bug.cgi?id=139767 > There are plenty of things that can be done, including using search > paths to try to find vmlinuz; or maybe even proposing a new standard > such as say for example /lib/modules/`uname -r`/vmlinux being a At the time when I was trying to fix this, I wasn't aware of any way to propose a new standard and get distributions to follow it - is there some way now? Informally I discussed this problem several times with many people without any resolution. As regards searching informal paths, this is extremely risky - get the wrong vmlinux and we end up with inaccurate results, which is worse than no results. > The abdication of responsibility and the lack of trying to solve the > usability issues is one of the things that really worries me about > *all* of Linux's RAS tools.

Yes, it's a I'm not abdicating responsibility: I no longer maintain oprofile, haven't for a long time, and the other contributors don't have any real time to spend on it either. I'm well aware there are improvements to be made: when I (and others) had time, this stuff was improving massively with each release. When Soren et al had a need for a simple tool + GUI, they should have helped out with this: it's simply good engineering to not duplicate efforts. I didn't even get a /single/ email. regards, john -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
