While developing my DPTF implementation for Linux I caused the outer skin of my test laptop to reach a temperature that would have caused burns to my legs if I had left it sitting on them for more than a couple of minutes. Now, I have working thermoreception, so I'd probably have noticed this and put it somewhere that wasn't my legs before that happened, but there are various scenarios in which people don't and manufacturers of objects that are intended to be put in your lap are kind of reluctant to design them in such a way that they could cause injury, which is why the manufacturer policies ensure that doesn't happen. If you're fully aware of the possible consequences of ignoring those policies then go wild. I think it's the wrong choice for most people, and as I said I think it's irresponsible to suggest people change the thermal policy in that way without ensuring they're aware of the possible consequences. If saying "You should only do this if you're ok with your laptop potentially becoming hot enough to burn human skin" is authoritarian then I guess I'm authoritarian?

Your work on reverse engineering DPTF seems abandoned. Is it that everything was upstreamed? Because there's still a performance gap between Windows and Linux. Also, why is Intel so reluctant on fixing this themselves? It looks so simple to me too fix this by releasing the docs and fixing thermald, and still, here we are having to use throttled for those wanting a little bit more punch. And finally, how is it that nobody it's creating a custom, patched thermald that takes all this into account? Is it that the process for reverse engineering is too complicated and that we don't have the full picture yet? It shouldn't be too difficult to read the values Windows takes and reverse engineer it, although it may be tougher than it seems at first.

  I worked on it to the extent that it worked for my use case, given it was a spare time project. It's all been merged upstream, and Intel (to their credit) are maintaining it now even though still refusing to document it.
