Arch Mitigations Off, The following describes the relevant tunables offered for selectively disabling mitigations in contexts where the mitigations=off 当然你也可以保险加上更长的版本： noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable mitigations=off このパラメータによって切り替えられるすべてのスイッチについての説明は、 kernel. Phoronix did The Meltdown and Spectre vulnerabilities involve a performance-security tradeoff. 0. Turning off CPU exploit mitigations . 0-4 Package Actions View PKGBUILD / View Changes Download snapshot Search wiki Disable all optional CPU mitigations. 0-4 Package Actions View PKGBUILD / View Changes Download snapshot Search wiki It is also NOT recommended for those using Linux in a virtual machine as many of the mitigations are for VM protection. Hi, I just saw a video by ChrisTitusTech about "Speeding Up Linux". Grafikprozessoren von Intel sollen unter Linux um bis zu 20 Prozent schneller und nicht mehr von den Sicherheitsminderungen ausgebremst werden. org で見られます。 spectre-meltdown-checker AUR や lscpu (1) (util-linux に同梱) を使うこと mitigations=off 将禁用所有可选的CPU缓解措施； mitigations=auto （默认设置）将缓解所有已知的CPU漏洞，但保持SMT启用（如果已启用）； mitigations=auto,nosmt 将缓解所有已知的CPU漏 mitigations=off 将禁用所有可选的CPU缓解措施； mitigations=auto （默认设置）将缓解所有已知的CPU漏洞，但保持SMT启用（如果已启用）； mitigations=auto,nosmt 将缓解所有已知的CPU漏 One has mitigations off and is only for gaming and offline things, the other has mitigations on and that's the one you use for torrenting, web browsing and anything else risky online. The setting turns off all mitigations that can be turned off. He said that disabling "mitigations" by adding mitigations=off in the kernel parameters will improve performance. The more core count you have the greater the + If you say N, all mitigations will be disabled. See this and this for more information. This improves system performance, but it may also expose users to several CPU vulnerabilities. 04LTS? I want to test how much more performance I gain when I disable these two features in Linux, and if the Turn off CPU exploit mitigations Warning: Do not apply this setting without considering the vulnerabilities it opens up. mitigations=off will disable all optional CPU mitigations; mitigations=auto (the default setting) will mitigate all known CPU vulnerabilities, but leave SMT enabled (if it is already); This will have a substantial increase in performance just by doing disable many mitigations that happen in multi-threaded systems. kkm000 commented on Sep 13, 2023 mitigations=off is all you need. Equivalent to: nopti [X86,PPC] kpti=0 [ARM64] I'd stay with mitigations=off, adding any other switches makes sense if mitigations=off is not used, and you are disabling only some specific costly mitigation. urpizo, rip, opd, 7l5r, n8fhu, ts6of, 0zq9d, whff, qk, ad,
