I was going through the following function __cpuinit detect_extended_topology where there is a talk about detecting the cpu topology.
I have read documentation intel IA32 sys programming guide about CPUID instruction. But i am having some doubts regarding what exactly is a "enumeration leaf".Does leaf mean a supported function for CPUID or is it something else. I am not able to correctly understand why we use a "leaf" terminology.
This maybe a trivial question but my google searches have done me no good.
thanks,
Punit.
