3604 CPUID V2 Extended Topology Enumeration Leaf\r
3605\r
3606 @note\r
3607 CPUID leaf 1FH is a preferred superset to leaf 0BH. Intel recommends first checking\r
3608 for the existence of Leaf 1FH and using this if available.\r
3609 Most of Leaf 1FH output depends on the initial value in ECX. The EDX output of leaf\r
3610 1FH is always valid and does not vary with input value in ECX. Output value in ECX[7:0]\r
3611 always equals input value in ECX[7:0]. Sub-leaf index 0 enumerates SMT level. Each\r
3612 subsequent higher sub-leaf index enumerates a higher-level topological entity in\r
3613 hierarchical order. For sub-leaves that return an invalid level-type of 0 in ECX[15:8];\r
3614 EAX and EBX will return 0. If an input value n in ECX returns the invalid level-type of\r
3615 0 in ECX[15:8], other input values with ECX > n also return 0 in ECX[15:8].\r
3616\r
3617 Software should use this field (EAX[4:0]) to enumerate processor topology of the system.\r
3618 Software must not use EBX[15:0] to enumerate processor topology of the system. This value\r
3619 in this field (EBX[15:0]) is only intended for display/diagnostic purposes. The actual\r
3620 number of logical processors available to BIOS/OS/Applications may be different from the\r
3621 value of EBX[15:0], depending on software and platform hardware configurations.\r
