MFC r342977 (by cem): amdtemp(4): Add support for Family 15h, Model >=60h

2019-01-22T21:35:25Z

Family 15h is a bit of an oddball. Early models used the same temperature register and spec (mostly[1]) as earlier CPU families. Model 60h-6Fh and 70-7Fh use something more like Family 17h's Service Management Network, communicating with it in a similar fashion. To support them, add support for their version of SMU indirection to amdsmn(4) and use it in amdtemp(4) on these models. While here, clarify some of the deviceid macros in amdtemp(4) that were added with arbitrary, incorrect family numbers, and remove ones that were not used. Additionally, clarify intent and condition of heterogenous multi-socket system detection. [1]: 15h adds the "adjust range by -49°C if a certain condition is met," which previous families did not have. Reported by: D. C. PR: 234657 Tested by: D. C.

MFC r340426 (by cem): amdtemp(4): Fix temperature reporting on AMD 2990WX

2019-01-22T21:34:25Z

Update the AMD family 17h temperature reporting based on AMD Tech Doc 56255 OSRR, section 4.2.1. For CPUS w/CUR_TEMP_RANGE_SEL set, scale the reported temperature into the range -49..206; i.e., subtract 49°C. Submitted by: gallatin@ Reported by: bcran@

MFC r340425 (by cem): amdsmn(4)/amdtemp(4): Attach to Ryzen 2 hostbridges

2019-01-22T21:33:14Z

As reported, tested, and patch supplied by Johannes. There may be future work to do to support multiple sensors, but for now, any sensor at all is a strict improvement for Ryzen 2 systems.

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Fix the deciKelvin to Celsius conversion in kernel.

2016-05-22T13:58:32Z

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)
