  Yes. Spectre2 can be and is being patched with a microcode update that partially disables branch prediction.

    What about meltdown?
    • anifal 9y ago
      Meltdown is mitigated by kernel page table isolation. See patch notes/ the attack paper

        That says nothing about the need to fully replace defective hardware to avoid the hardware problem.

          That says nothing about the possibility to patch the missing page table isolation with a microcode update. They have enough spare registers for a seperate C3, they could workaround the TLB flush. Since the fdiv bug HW problems are not HW problems anymore.
