Created attachment 254112 [details] Patch for amdsmn.c and amdtemp.c to support AMD Ryzen 7 "Rembrandt" The attached patch adds support for AMD Ryzen 7 "Rembrandt" processors (family 0x19, model 0x40-0x4f) to the amdsmn(4) and amdtemp(4) drivers, enabling temperature readings of these CPUs via sysctl. The sensors work the same as for the "Raphael" processors (model 0x60-0x6f), only the PCI device ID differs. The patch applies cleanly to (15-) current, 14-stable, including 14.1-RELEASE. It should also work with 13, as only the PCI device ID is changed. Tested with Ryzen 7 PRO 6850U (family 0x19, model 0x44, https://bsd-hardware.info/?probe=0a2c02f944).
