I'm not sure what qualifies as > interesting, but here's its description: Nvm, I thought you might have zen2 for some reason. I have the same device with zen1 X390 and it seems to work fine here: intsmb0 pnpinfo vendor=0x1022 device=0x790b subvendor=0x1849 subdevice=0xffff class=0x0c0500 at slot=20 function=0 dbsf=pci0:0:20:0 handle=\_SB_.PCI0.D07C ACPI I/O ports: 0xb00-0xb0f smbus0 jedec_dimm0 at addr=0xa2 jedec_dimm1 at addr=0xa6 jedec_dimm2 at addr=0xaa jedec_dimm3 at addr=0xae (Different subvendor/subdevice? Not sure that matters.) Same I/O port range. My SPD addresses are at different locations, but that is expected. > intsmb0 pnpinfo vendor=0x1022 device=0x790b subvendor=0x1462 > subdevice=0x7a33 class=0x0c0500 at slot=20 function=0 dbsf=pci0:0:20:0 > handle=\_SB_.PCI0.D028 > ACPI I/O ports: > 0xb00-0xb0f > smbus0 > jedec_dimm0 at addr=0xa4 > jedec_dimm1 at addr=0xa6 > FreeBSD source calls 790b 'AMDCZ'. Yeah, it is an old piece of IP, introduced in family 15h model ~70h ("Carrizo" APU, I guess). They reuse it in Zen. -- You are receiving this mail because: You are the assignee for the bug.help
