* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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
* Fix the deciKelvin to Celsius conversion in kernel.Luiz Otavio O Souza2016-05-221-1/+1
| | | | | | | | | | | | | | 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) Notes: svn path=/head/; revision=300421

and newer CPUs (including Core 2 and Core / Core 2 based Xeons). The driver attaches to each cpu device and creates a sysctl node in that device's sysctl context (dev.cpu.N.temperature). When invoked, the handler binds to the appropriate CPU to ensure a correct reading.
