1656 Virtual SMP uses the processor's VPEs to implement virtual
1657 processors. In currently available configuration of the 34K processor
1658 this allows for a dual processor. Both processors will share the same
1659 primary caches; each will obtain the half of the TLB for it's own
1660 exclusive use. For a layman this model can be described as similar to
1661 what Intel calls Hyperthreading.

1680 is presenting the available TC's of the core as processors to Linux.
1681 On currently available 34K processors this means a Linux system will
1682 see up to 5 processors. The implementation of the SMTC kernel differs
1683 significantly from VSMP and cannot efficiently coexist in the same
1684 kernel binary so the choice between VSMP and SMTC is a compile time
1685 decision.
