2018-05-13hwmon: (k10temp) Use API function to access System Management NetworkGuenter Roeck1-5/+6
The SMN (System Management Network) on Family 17h AMD CPUs is also accessed from other drivers, specifically EDAC. Accessing it directly is racy. On top of that, accessing the SMN through root bridge 00:00 is wrong on multi-die CPUs and may result in reading the temperature from the wrong die. Use available API functions to fix the problem. For this to work, add dependency on AMD_NB. Also change the Raven Ridge PCI device ID to point to Data Fabric Function 3, since this ID is used by the API functions to find the CPU node.

2018-02-12hwmon: (k10temp) Only apply temperature offset if result is positiveGuenter Roeck1-1/+4
A user reports a really bad temperature on Ryzen 1950X. k10temp-pci-00cb Adapter: PCI adapter temp1: +4294948.3°C (high = +70.0°C) This will happen if the temperature reported by the chip is lower than the offset temperature. This has been seen in the field if "Sense MI Skew" and/or "Sense MI Offset" BIOS parameters were set to unexpected values. Let's report a temperature of 0 degrees C in that case.
