Family vs Asset Model

[brandonkimbk]

While trying to figure out how to expose CPU ID Family, Model, Stepping and Microcode information in bmcweb: https://gerrit.openbmc-project.xyz/c/openbmc/bmcweb/+/46884

I saw that smbios-mdr was exposing information such as Quad-Core Intel Xeon processor 3200 Series as "Family" under the xyz.openbmc_project.Inventory.Item.Cpu interface.

smbios-mdr/include/cpu.hpp

Lines 48 to 79 in e7cf319

	static const std::map<uint8_t, const char*> familyTable = {
	{0x1, "Other"},
	{0x2, "Unknown"},
	{0x10, "Pentium II Xeon processor"},
	{0xa1, "Quad-Core Intel Xeon processor 3200 Series"},
	{0xa2, "Dual-Core Intel Xeon processor 3000 Series"},
	{0xa3, "Quad-Core Intel Xeon processor 5300 Series"},
	{0xa4, "Dual-Core Intel Xeon processor 5100 Series"},
	{0xa5, "Dual-Core Intel Xeon processor 5000 Series"},
	{0xa6, "Dual-Core Intel Xeon processor LV"},
	{0xa7, "Dual-Core Intel Xeon processor ULV"},
	{0xa8, "Dual-Core Intel Xeon processor 7100 Series"},
	{0xa9, "Quad-Core Intel Xeon processor 5400 Series"},
	{0xaa, "Quad-Core Intel Xeon processor"},
	{0xab, "Dual-Core Intel Xeon processor 5200 Series"},
	{0xac, "Dual-Core Intel Xeon processor 7200 Series"},
	{0xad, "Quad-Core Intel Xeon processor 7300 Series"},
	{0xae, "Quad-Core Intel Xeon processor 7400 Series"},
	{0xaf, "Multi-Core Intel Xeon processor 7400 Series"},
	{0xb0, "Pentium III Xeon processor"},
	{0xb3, "Intel Xeon processor"},
	{0xb5, "Intel Xeon processor MP"},
	{0xd6, "Multi-Core Intel Xeon processor"},
	{0xd7, "Dual-Core Intel Xeon processor 3xxx Series"},
	{0xd8, "Quad-Core Intel Xeon processor 3xxx Series"},
	{0xd9, "VIA Nano Processor Family"},
	{0xda, "Dual-Core Intel Xeon processor 5xxx Series"},
	{0xdb, "Quad-Core Intel Xeon processor 5xxx Series"},
	{0xdd, "Dual-Core Intel Xeon processor 7xxx Series"},
	{0xde, "Quad-Core Intel Xeon processor 7xxx Series"},

Looking at the Redfish Resource and Schema guide at https://www.dmtf.org/sites/default/files/standards/documents/DSP2046_2021.2.pdf

Section 6.86.6 at page 668, we see:

"Manufacturer": "Intel(R) Corporation",
"Model": "Multi-Core Intel(R) Xeon(R) processor 7xxx Series",
"ProcessorId": {
    "VendorId": "GenuineIntel",
    "IdentificationRegisters": "0x34AC34DC8901274A",
    "EffectiveFamily": "0x42",
    "EffectiveModel": "0x61",
    "Step": "0x1",
    "MicrocodeInfo": "0x429943"
},

According to this, it looks like instead of "Family" (which gets parsed as EffectiveFamily in bmcweb), we should really be adding this "Family" information to xyz.openbmc_project.Inventory.Decorator.Asset interface's .Model inventory, which is already mapped correctly in bmcweb https://github.com/openbmc/bmcweb/blob/master/redfish-core/lib/processor.hpp#L294-L302
