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! -Yazen

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.

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. arch/x86/kernel/amd_nb.c | 6 ++++++ 1 file changed, 6 insertions(+)
