    Phoronix: Zhaoxin 7-Series x86 CPUs Mitigated For Spectre V2 + SWAPGS

    When it comes to the Zhaoxin x86-compatible processors coming out of VIA's joint venture in Shanghai, their forthcoming 7-series (KX-7000) has hardware mitigations in place for some CPU vulnerabilities...

    Any benchmarks?

    It might also be an interesting alternative to IntelAMD duopoly...

      In reference to this quote from Michael's article:

      Intel recently reworked the KVM code within x86/cpu to allow those CPUs to make use of the Intel KVM driver code for virtualization.
      That support can be found in this commit:

      https://git.kernel.org/pub/scm/linux...fa3c71cdf8c44a

      And this comment was added to the commit:

      Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to any CPU that supports the IA32_FEAT_CTL MSR and thus VMX functionality. This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.

        You'd trust Chinese-designed CPU?

          I trust nobody.

          All CPU makers are shady corporations with shady reputation, no exceptions.

          I treat all hardware as if done by the worst evil in existence. You may call that evil as China, USA, North Korea, Canada, Japan, European Union, Congo, Russia, Malaysia, Uzbekistan, Sudan, United Arab Emirates, United Nations, United Kingdom, etc.

          After all, most electronics are manufactured in China.

          There's no trust, only a fake sense of it.

            A lot is, but not most.

            Taiwan, Malaysia, Indonesia, Japan, Germany, USA all also manufacture chips.

              Each withtheir own shady interests, with their governments having their own agenda. There's no hope, after all.

              Not everything is manufactured in China, but most is assembled in China.

                Most relevant question would be, which potential spying party could be damaging to you personally. The rest you can just ignore. For example, you work for government or have to routinely handle some sort of sensitive data (business secrets). You don't want Chinese cloning your widgets/business and become a competition or whatever you do for government leak out.. so forget using their hardware and software. Just random examples.

                If all you do is watch porn and share cat pics, Chinese hardware-software are fine.

                  Why China is the only evil government?

                  Every spying party is evil, no exceptions.

                  Computers are used for everything. Even a grandma if it's a real computer user.
