amdtemp does not recognize the AMD Ryzen Threadripper 3970X CPU on the TRX40 platform, and reports no temperatures for the chip. No dev.cpu.*.temperature OIDs are created after loading the module. I have tried the driver with Zen 2 patches from base r350624 (amdtemp and amdsmn) as described in bug #239607 and re-installed both drivers from that source code, then loaded the newly compiled amdsmn and amdtemp. The modules still won't provide any temperature information however. The mainboard in my case is an ASRock TRX40 Taichi.

The driver support for Zen 2 hasn't been MFCed from 13-CURRENT. This is the patch I use to add support for the Ryzen 3600X in home server to amdtemp: Index: sys/dev/amdsmn/amdsmn.c =================================================================== --- sys/dev/amdsmn/amdsmn.c (revision 356412) +++ sys/dev/amdsmn/amdsmn.c (working copy) @@ -59,6 +59,7 @@ #define PCI_DEVICE_ID_AMD_15H_M60H_ROOT 0x1576 #define PCI_DEVICE_ID_AMD_17H_ROOT 0x1450 #define PCI_DEVICE_ID_AMD_17H_M10H_ROOT 0x15d0 +#define PCI_DEVICE_ID_AMD_17H_M30H_ROOT 0x1480 struct pciid; struct amdsmn_softc { @@ -90,6 +91,12 @@ .amdsmn_addr_reg = F17H_SMN_ADDR_REG, .amdsmn_data_reg = F17H_SMN_DATA_REG, }, + { + .amdsmn_vendorid = CPU_VENDOR_AMD, + .amdsmn_deviceid = PCI_DEVICE_ID_AMD_17H_M30H_ROOT, + .amdsmn_addr_reg = F17H_SMN_ADDR_REG, + .amdsmn_data_reg = F17H_SMN_DATA_REG, + }, }; /* Index: sys/dev/amdtemp/amdtemp.c =================================================================== --- sys/dev/amdtemp/amdtemp.c (revision 356412) +++ sys/dev/amdtemp/amdtemp.c (working copy) @@ -96,6 +96,7 @@ #define DEVICEID_AMD_MISC16_M30H 0x1583 #define DEVICEID_AMD_HOSTB17H_ROOT 0x1450 #define DEVICEID_AMD_HOSTB17H_M10H_ROOT 0x15d0 +#define DEVICEID_AMD_HOSTB17H_M30H_ROOT 0x1480 static const struct amdtemp_product { uint16_t amdtemp_vendorid; @@ -118,6 +119,7 @@ { VENDORID_AMD, DEVICEID_AMD_MISC16_M30H, true }, { VENDORID_AMD, DEVICEID_AMD_HOSTB17H_ROOT, false }, { VENDORID_AMD, DEVICEID_AMD_HOSTB17H_M10H_ROOT, false }, + { VENDORID_AMD, DEVICEID_AMD_HOSTB17H_M30H_ROOT, false }, }; /*

Alright, this was a user mistake! I compiled the correctly patched source code, and installed the modules in /boot/modules/. It seems modules in /boot/kernel/ are loaded first though, and I still had the old version in there. So I loaded the old version. I corrected that and can now confirm that this works for Zen 2 Threadrippers as well, e.g.: $ sysctl dev.cpu.62.temperature dev.cpu.62.temperature: 84.6C
Is this still not merged to stable/12 and stable/11 though?
(In reply to Ed Maste from comment #7) Correct, AFAIK.
Actually, Mav MFC'd them to 12/11. Maybe just not in 12.1. *** This bug has been marked as a duplicate of bug 239607 ***
