@rrwinterton can you post some reference to the doc that says this number corresponds to Willow Cove? |

note 8c = 140 is the one that sde -tgl exposes but https://en.wikichip.org/wiki/intel/cpuid confirms 141

move up 2 lines because willow cove is the successor to sunny cove (icelake)

Confirmed Tigerlake does not detect currently: Was With your change sde -tgl works: sde -tgl -- ./cpu-info | head If you have a real Tigerlake available, could you verify a package name? SDE seems to fill them in wrong Testing icelake, the predecessor of tigerlake, shows Sunny Cove. sde -icl -- ./cpu-info | head |
removed incomplete modification in naming
moved willow_cove up two lines to be next to sunny_cove
made the enum consistent with uarch naming following sunny_cove

Willow Cove is that micro architecture of Tiger Lake CPU's from Intel. Willow Cove architecture has an Intel Family 6, Model 0x8C or 0x8D. |
Added comments below and did fix of incomplete file per frank's comments. Intel Willow Cover is part of the Tiger Lake CPU family microarchitecture. Intel Family 6, Model 0x8C or 0x8D |
