hwmon: (k10temp) Use API function to access System Management Network

2018-05-22T16:56:21+00:00

commit 3b031622f598481970400519bd5abc2a16708282 upstream. 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.

hwmon: (k10temp) Add support for AMD Ryzen w/ Vega graphics

2018-04-29T09:35:51+00:00

commit 877d8948d0aa402fbbede138fc73432bb335b65f upstream. Enable k10temp for AMD Ryzen APUs w/ Vega Mobile Gfx. Based on patch from René Rebe . Dropped temperature offsets since those are not supposed to apply for the affected CPUs.

hwmon: (k10temp) Add temperature offset for Ryzen 2700X

2018-04-29T09:35:51+00:00

commit 1b59788979acd230b9627276c76f6e6ba2c4709c upstream. Ryzen 2700X has a temperature offset of 10 degrees C. If bit 19 of the Temperature Control register is set, there is an additional offset of 49 degrees C. Take this into account as well.

x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

2018-02-15T00:15:52+00:00

x86_mask is a confusing name which is hard to associate with the processor's stepping. Additionally, correct an indent issue in lib/cpu.c.

hwmon: (k10temp) Only apply temperature offset if result is positive

2018-02-12T22:23:29+00:00

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.
