[LLVMdev] Request for Help: Teach ARM target to auto-detect cpu / subtarget features
Hi all,
I've just filed PR12794: Add ARM cpu / subtarget features auto-detection. And I would very much appreciate the community's help to implement this.
What motivated this? Well this:

I believe one of the reason the benchmark numbers are totally bogus is that the compilation are done on ARM hosts. Given the benchmarks are

mcelog
Ok, we've got a new machine that's throwing ECC errors. I've gotten new
memory overnighted to me from the manufacturer, and replaced it, oops, not
that end of the bank, as their support told me, this end of the bank, as
the mobo manual I found online shows (Supermicro).
Still throwing errors. Ok, try to get more info.... Last week, I moved

In A UEFI World, "rm -rf /" Can Brick Your System

Yes, I kind of like "rm -rf /". If my memory doesn't fail me, long ago it
was one of the tricky questions in sysadmin exam (not that anymore if I
read what you, Michael, write further correctly...). Anyway,

There was also this article recently that pointed out that if the box boots via UEFI, you may brick the machine, depending on setup.

[RFC] Speculative Execution Side Effect Suppression for Mitigating Load Value Injection
I'm also a bit unclear on that point. I think one input here has to be:
what are some example, existing codebases we want to mitigate, and what
should the user experience be to mitigate them? I don't think we can make
good engineering tradeoffs without having concrete use cases to evaluate.
Another point: it seems some mitigation options have already been added to

odd mcelogd problem
CentOS 6.4, 2.6.32-358.11.1.el6.x86_64
(And no, I can't just upgrade - the users have to be sure that the
computational results will be correct....)
It's throwing ECC errors. Trying to start mcelogd, first it said nothing.
Restart told me "Please load edac_mce_amd module." I did a modprobe
edac_mce_amd, and lsmod tells me it's in. But now

Cannot open /dev/mcelog
Hi there,
I'am running CentOS 5.1 on a Dual AMD Opteron QuadCore System, without
major issues so far.
But if I call mcelog I'am getting the message "Cannot open /dev/mcelog"
... because it's not there.
I'am running 2.6.18-53.1.4.el5xen kernel, is this related in any form? I
found something similar for the debian universe:
