2023-02-04coretemp: Only log critical temperature eventssadaszewski
According to the Intel manual https://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-vol-3b-part-2-manual.pdf the Thermal Status (0) and Thermal Status Log (1) bits report only a high temperature on the CPU, not a critical temperature as suggested in the coretemp driver. Check the Critical Temperature Log (5) instead. The critical temperature waives guarantees of correct function, therefore the CPU could have for example written some wrong values into memory at that point and the OS should be stopped ASAP as the state is no longer reliable.

2021-09-24Make CPU children explicitly share parent unit numbers.Alexander Motin
Before this device unit number match was coincidental and broke if I disabled some CPU device(s). Aside of cosmetics, for some drivers (may be considered broken) it caused talking to wrong CPUs.

2021-07-29coretemp(4): Switch to smp_rendezvous_cpus().Alexander Motin
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.

2020-02-26Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki
r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
2019-05-20Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer
This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
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. Notes: svn path=/head/; revision=326255

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.
