1829 This is a kernel model which is known a VSMP but lately has been
1830 marketesed into SMVP.
1831 Virtual SMP uses the processor's VPEs to implement virtual
1832 processors. In currently available configuration of the 34K processor
1833 this allows for a dual processor. Both processors will share the same
1834 primary caches; each will obtain the half of the TLB for it's own
1835 exclusive use. For a layman this model can be described as similar to
1836 what Intel calls Hyperthreading.

1855 is presenting the available TC's of the core as processors to Linux.
1856 On currently available 34K processors this means a Linux system will

1858 significantly from VSMP and cannot efficiently coexist in the same
1859 kernel binary so the choice between VSMP and SMTC is a compile time
