Intel released an update to the Meltdown and Spectre mitigation guide, revealing that it stopped working on mitigations for some processor series. Intel says processors with a “Stopped”” status will not receive microcode updates. The reasons vary from “”redesigning the CPU micro-architecture is impossible or not worth the effort”” to “”it’s an old CPU”” and “”customers said they don’t need it”” Most of these processors are old CPU models
