This is a kernel model which is also known a VSMP or lately

This is a kernel model which is known a VSMP but lately has been
marketesed into SMVP.
Virtual SMP uses the processor's VPEs to implement virtual
processors. In currently available configuration of the 34K processor
this allows for a dual processor. Both processors will share the same
primary caches; each will obtain the half of the TLB for it's own
exclusive use. For a layman this model can be described as similar to
what Intel calls Hyperthreading.

This is a kernel model which is known a SMTC or lately has been

is presenting the available TC's of the core as processors to Linux.
On currently available 34K processors this means a Linux system will
see up to 5 processors. The implementation of the SMTC kernel differs
significantly from VSMP and cannot efficiently coexist in the same
kernel binary so the choice between VSMP and SMTC is a compile time
decision.
