1652 Virtual SMP uses the processor's VPEs to implement virtual
1653 processors. In currently available configuration of the 34K processor
1654 this allows for a dual processor. Both processors will share the same
1655 primary caches; each will obtain the half of the TLB for it's own
1656 exclusive use. For a layman this model can be described as similar to
1657 what Intel calls Hyperthreading.

1676 is presenting the available TC's of the core as processors to Linux.
1677 On currently available 34K processors this means a Linux system will
1678 see up to 5 processors. The implementation of the SMTC kernel differs
1679 significantly from VSMP and cannot efficiently coexist in the same
1680 kernel binary so the choice between VSMP and SMTC is a compile time
1681 decision.
