  • This is a patch from the hardware vendor so I am assuming that the ask is not that the hardware vendor take responsibility but that they not release buggy hardware. That is what I mean about the validation issue.

    The attack vector is shared in the patch so it isn’t entirely a theory.

    There is a comment from Linus about how this patch is only needed for some hardware and doesn’t apply to others but I don’t get his relevance there as different hardware validates against different use cases and their source logic might be entirely disparate.

    So my validation talk is simply saying that bugs happen. My concern here is what more should a hardware vendor do beyond submitting a kernel patch? You can’t just not have the bug, and if you recall the part someone else will just keep theirs in the field and take all the market share and roll the dice that their bugs don’t get exploited.


  • Is this really the hardware vendor’s problem though? It’s the consumers problem.

    I bring up full validation because the concern here is putting in a speculative fix. If the ask is, why was the hardware like that in the first place the answer is because it can’t be fully validated. If the ask is why should a speculative fix go into the Kernel it is because the consumers are not on top of tree and if a fix has a chance of never being exploited it needs to be pulled in years ahead so it goes into an LTR that customers migrate to BEFORE the issue comes up.


  • Fully validating hardware is an insane task that hasn’t been really done in years. It would mean 5 years between chip releases and a 2-5X in cost to produce, and people wouldn’t follow the validated configs anyways. If we followed the validated hardware spec we would have 50 min boot times and not go past a 3.5Ghz clock.

    People have the choice today on if they want to run on validated hardware. You can opt in to get a 2.8Ghz part that supports 2666MT/s that is mostly tested and validated, or you can get a 5Ghz part that supports 6000MT/s that is only partially validated. They cost the same price. What do folks think people pick?



  • The intent is to make the distributed version more true to the real original. None of us got to see the original. The original is a bunch of data on various machines. What we saw was a low quality save file of the original, cut down and watered down to the specs of 4:3 CRT televisions and broadcast hardware of the time. That version develops artefacts not intended when distributed on modern media.

    Now this probably isn’t using original source files but it is possible. Remaster as a term also is used when they take the final master copy and rerun it through more modern technologies to get a cleaner output which is what I expect happened here.





  • For the US the pretty well known policy bangers are The New Deal and The Interstate Highway System both which are not just socialism but Federal level socialism.

    All state run armed forces are by definition socialist in nature. Mercenary armed forces have been used many times to great effect but the backbone of most armed conflicts are the most socialist structure you could create.

    Every large modern religion (abrahamic, hindu, buddhist) is socialist in nature and got to the level they are now due to socialist policy.
