Intel CEO: Patches will come to 90% of chips in the next week
This is <i>only</i> Spectre, not Meltdown.  Meltdown requires KPTI, which depends on your OS.  For OSs that did not enjoy months of advanced disclosure (which is: any OS that isn&#x27;t Windows, MacOS or mainline Linux), that work is ongoing and will depend on the OS.  (Speaking for SmartOS&#x2F;illumos, that work is reasonably far along and making promising progress -- but we don&#x27;t yet have a functional prototype.)<p>As for Spectre, these are just the microcode updates that have the additional MSRs that allow system software to mitigate certain variants of Spectre attack against the system software itself.  They are necessary, but emphatically not sufficient -- and it would disingenuous for Intel to pretend that this in any way means that 90% of systems are protected from Meltdown and Spectre.
