Messages in this thread Patch in this message |  | | From | Guenter Roeck <> | Subject | [PATCH 1/2] x86/amd_nb: Add support for Raven Ridge CPUs | Date | Sat, 28 Apr 2018 18:54:38 -0700 |
| |
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.
