Requesting cpuid function ID 0x80000006 on a Ryzen 7 3700X returns 0x01009140.
So the value for the L3 cache associativity (bits 12-15) is 0x9
According to the spec(PDF page 75) this value is reserved.
Any idea were the issue lies here?
Is the spec wrong or the CPU bugged?
Edit: We now have a Ryzen 5 3600 which shows also returns 0x9 bits 12-15.
No, that L2/L3 cache associativity value (0x9) means "Please look at CPUID.8000_001D"
