coretemp(4): Switch to smp_rendezvous_cpus().

2021-08-13T01:55:55Z

Use of smp_rendezvous_cpus() instead of sched_bind() allows to not block indefinitely if target CPU is running some thread with higher priority, while all we need is single rdmsr/wrmsr instruction call. I guess it should also be much cheaper than full thread migration. MFC after: 2 weeks Sponsored by: iXsystems, Inc. (cherry picked from commit 74f80bc1af2ffd56ec290f610c80e46f768731a0)

hwpmc: Always set pmc_cpuid to something pmc_cpuid was uninitialized for most AMD processor families. We can still populate this string for unimplemented families. Also added a CPUID_TO_STEPPING macro and converted existing code to use it. Reviewed by: mav Sponsored by: iXsystems, Inc. Differential Revision: https://reviews.freebsd.org/D25673

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C reference and as result, the temperature read in sysctl(8) now exibits a +0.1C difference. This commit fix the kernel references to match the reference value used in sysctl(8) after r285994. Sponsored by: Rubicon Communications (Netgate)
