Author: emaste Date: Wed May 16 01:55:52 2018 New Revision: 333661 URL: https://svnweb.freebsd.org/changeset/base/333661 Log: intel-ucode-split: list platform ids based on processor_flags The Intel CPU "Platform Id" is a 3-bit integer reported by a given MSR. Intel microcode updates have an 8-bit field to indicate Platform Id compatibility - one bit in the mask for each of the possible Platform Id values. To simplify interpretation, report the Platform Id mask also as a list.
