--- Comment #9 from commit-h...@freebsd.org --- A commit references this bug: Author: kib Date: Wed Sep 25 13:36:56 UTC 2019 New revision: 352684 URL: https://svnweb.freebsd.org/changeset/base/352684 Log: x86: Fall back to leaf 0x16 if TSC frequency is obtained by CPUID and leaf 0x15 is not functional. This should improve automatic TSC frequency determination on Skylake/Kabylake/... families, where 0x15 exists but does not provide all necessary information. SDM contains relatively strong wording against such uses of 0x16, but Intel does not give us any other way to obtain the frequency. Linux did the same in the commit 604dc9170f2435d27da5039a3efd757dceadc684.
