個人的には、CPUの x16を x8/x8にばらせる構成にして、Gen4 x16(x16 or x8)/Gen3 x1/Gen4 x16(x0 or x8)/Gen4 x4なM-ATXマザーがあると一番おもしろそうなのですがねぇ(x8/x8にばらした所に25G NIC + 12G/24G SAS HBAを差し込むのが面白そう)

_ [FreeBSD][Ryzen]amdtemp on Ryzen 9 9950X

備忘録としてまとめておく

既に動くRyzen 9 7950Xとの比較
- amdsmn driverがprobeする hostb0@pci0:0:0:0のPCI device IDは同一 (device=0x14d8)
- amdsmn/amdtemp driver共に FamilyID checkで拒絶される
FamilyID/ModelIDまとめ

Processor	FamilyID	ModelID	Stepping
Ryzen 9 9950X	1Ah	44h	0
Ryzen 9 7950X	19h	61h	2

最低限必要な修正
- 1Ah Family support
- 1Ah Family向けのamdtemp_probe_ccd__sensors19h相当関数
