unction 8000_0005h — L1 Cache Information
Input:
EAX = 8000_0005h
Output:
EAX = Reserved
EBX = TLB Information
ECX = L1 Data Cache Information
EDX = L1 Instruction Cache Information
Function 8000_0005h returns information about the processor’s on-chip L1 caches and
associated TLBs. Tables 33, 34, and 35 provide the format for the information returned
by the 8000_0005h function.
