Hey,
Intel has mentioned that they are working on a new microcode which can
be used to detect L1TF conditions.
Anyone is working on it? I was thinking to start crafting patches
based on the description of the MSR and post them here for review.
But if someone is already busy with that I would rather review them :-)

There are no details currently available. Intel are planning to get us
production signed alpha builds of microcode as soon as they've worked
out why the latest build isn't working.

Sure. But the PDF is there. Or are you saying it is pointless as they may
change the PDF again?

1) Which PDF?
2) Is this secrit sauce or can we just discuss that on LKML?
Thanks,

It's been shared with some partners (but really doesn't say much yet, just
that the MSR has a couple of counts that help to detect L1TF attacks).

Yes secrit sauce. No discussion on public lists yet.

Is there any reason why this PDF can't be distributed on that very list
where all people subscribed are briefed, rubberstamped and fumigated?
