In what order are the CPUs discovered?

Hi

Where can I find out, the order in which the CPUs are discovered?

When having:
  - Multiple sockets.
  - Multiple cores.
  - Hyper-threading (HTT).

E.g. a single Socket with two cores and HTT enabled on both cores.
This would be 4 CPUs.
Would cpu0 and cpu1 be the first core, and cpu2 and 3 the second core?

What happens if HTT is disabled on core0 and enabled on core1?
 Would I see cpu0, cpu2,cpu3?
  or would it be cpu0, cpu1, cpu2 ?

Any suggestions on where I could find information on this would be appreciated.

  Thanks

     Henry
