[PATCH 1/2] x86/amd_nb: Add support for Raven Ridge CPUs

[PATCH 1/2] x86/amd_nb: Add support for Raven Ridge CPUs

[Guenter Roeck]

Add Raven Ridge root bridge and data fabric PCI IDs.
This is required for amd_pci_dev_to_node_id() and amd_smn_read().

Signed-off-by: Guenter Roeck <linux@roeck-us.net>

This patch is a prerequisite for the second patch in the series.
I'll be happy to apply both patches through hwmon if that is acceptable
(and Cc: stable for 4.16+). If not, I'll be happy to wait for this patch
to be available upstream.

Since that there is no public documentation available for Raven Ridge,
PCI IDs are derived from output of lspci.

[PATCH 2/2] hwmon: (k10temp) Use API function to access System Management Network

[Guenter Roeck]

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, 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.

This should have been 0x15eb. I'll resend after a week or so, waiting for more feedback.

Yes, that only matters for Raven Ridge CPUs (eg 2200G, 2400G).

I think the nomenclature we decided upon at the time was

...AMD_<family>H_M<model>H...

PCI_DEVICE_ID_AMD_15H_M10H_F3, for example.

And in this case, it should be

PCI_DEVICE_ID_AMD_17H_M<which model is RV>H_F<PCI function number>

Yazen, which is the first model of Raven Ridge?

Thx.

2400G is model 17 (0x11). I was unable to find information if there are
other chips/models using the same set of PCI IDs.

I'll wait for additional feedback before resending.

There are other models using the same set of IDs, but the first is 10h.

Also, the F3 IDs for Fam17h and Fam17hMod10h are used in both amd_nb.c
and k10temp.c. Can you please delete the F3 IDs from these files and add
them to "include/linux/pci_ids.h"?

Thanks!

Ok, I'll make it PCI_DEVICE_ID_AMD_17H_M10H_ROOT and
PCI_DEVICE_ID_AMD_17H_M10H_DF_F{3,4}.

I'll be happy to do that. However, my preference would be to do that
in a separate patch. I would like to see this patch and patch 2/2
applied to 4.16+ since together they fix a potential race condition
as well as temperature reporting problems with multi-die Zen chips
(Threadripper and EPYC). The pci_id.h changes are not bug fixes
and would be more appropriate for v4.18.
