    So a "F1 to continue" on every boot, yeah that will really fly.

      By the way did Linus say that people who care about security disable Hyperthreading anyway? Where are all the trolls who called us idiots when we said that HT is overrated and not a big deal to disable? Where are all the morons who namecalled us and cried that they would lose 50% of performance? They don't seem to comment anymore...

        It doesn't have to be every boot... asking once ought to be sufficient.

        I'd say those trolls were just a vocal minority and were more butthurt over the fact their non-SMT CPU didn't have more performance for the same core count.

          It's kinda sad that when I'm saying something here people disregard me, but if it's Linus then, "Oh, God, he's so right".
          Yeah there's too many retarded fanboys on this forum who are allergic to facts.

            It's not about hate. What I truly despise (and maybe birdie as well) is people spreading nonsense (to put it nicely) and refusing to accept facts, and there's no shortage of them on this forum.

              Amen. Took the words right out of my mouth (well I'd be slightly less vulgar tho, yeah even me, lol).

              #1 most annoying fucking resistance someone who GENUINELY wants to improve Linux receives... is from the Linux fanboys/zealots who think their OS is pure perfection, ironically enough. Windows or other OS fanboys offer zero resistance here, so they're completely insignificant to me.

                So where did Linus say SMT/HT is insignificant? Or putting words in people's mouth is your hobby?

                For all you know, his "people who care about security" is actually the politically correct term for "paranoid retards". Makes you think.

                  When performance goes down by 50% on some loads, people need to start asking themselves whether it was worth it.
                  You say, that you can balance out performance against security?
                  You say that a noticeable performance decrease that still leaves much more power than is lost is worth leaving a well known security hole in the operating system almost the whole earth is powered by?
                  When "some people" ask themselves something, then let these people decide themselves whether they like to deactivate security in their operating system.

                  It's apparently better to just disable SMT entirely, which is what security-conscious people do anyway.
                  Yes it obviously is!
                  Oh yeah, sure. Those companies that are running their phone system in the cloud simply walk in the building of their service providers and switch HT off!
                  People using military devices or running nuclear power plants are of course specialists who will switch HT off!
                  You know, even my dog would be able to switch HT off, that easy it is. Cause everyone is born as an IT professional
                  The view you share is just a disrespectful view on people who can't be aware of these issues!

                  I think we should use the same logic as for L1TF: we default to something that doesn't kill performance.
                  Oh, shall we? Why don't we just disable memory protection at all? Wouldn't it give us the performance boost we need? I mean, who cares about security would surely switch it on! HA HA HA!

                  This is not funny!
                  You pass the buck on Linux distributors and cloud providers who can be blamed for not opting in security.
                  You pass the buck on providers of security sensitive environments for not opting in security.
                  You pass the buck on private users for not opting in security.

                  You destroy trust in the Linux kernel with this attitude!

                  There is nothing to complain about having an opt out for security in order to get more performance. Even a professional cloud supplier may take the risk on his own and opt out.
                  But in my honest opinion there is no excuse for putting performance before security. This does not satisfy the expectations for making responsible decisions meeting the requirements of this position.

                    It is still fucking retarded. What Linus meant. Let me translate to non-moderated Linus: "The idiots will cripple themselves anyway, so we don't have to do it for them."

                      Why don't you just underclock your CPU to 1 Mhz, and remove all out-of-order execution, that will easily give you a massive security boost. I mean, who cares about performance would surely clock it back on! HA HA HA!




                      Performance > Security. Within limits obviously. Nobody fucking buys a new CPU for security and I sure don't want opinionated people like yourself to ruin the performance I PAID FOR.
