Hi,
the microcode revision guidance from Intel is revised once again [1] (1 Mar).
It looks like the following:
>Intel document only clears the 0xc2 microcode on *some* parts with CPUID 506E3 >(INTEL_FAM6_SKYLAKE_DESKTOP stepping 3). For the Skylake H/S platform it's OK >but for Skylake E3 which has the same CPUID it isn't (yet) cleared.
is no longer a problem. CPUID 506E3 with both Skylake H/S and Skylake Xeon E3 is labelled as "production" now.
Could we drop { INTEL_FAM6_SKYLAKE_DESKTOP, 0x03, 0xc2 } from spectre_bad_microcodes?
