amdtemp(4): Remove dead code that snuck in with r357190

2021-03-04T15:09:18Z

I intended to remove this before committing, but neglected to. (cherry picked from commit cc3b01385bfd7e7f67866c4ac0a1b43370d7e6b7)

amdtemp(4): Add support for Family 17h CCD sensors

2021-03-04T15:05:09Z

Probe Family 17h CPUs for up to 4 (Zen, Zen+) or 8 (Zen2) CCD temperature sensors. These were discovered by Ondrej Čerman (https://github.com/ocerman) and collaborators experimentally, and are not currently documented in any datasheet I have access to.

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

2019-01-22T21:04:03Z

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.

amdtemp(4): Fix temperature reporting on AMD 2990WX 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.

amdsmn(4)/amdtemp(4): Attach to Ryzen 2 hostbridges 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.
