1827 This is a kernel model which is known a VSMP but lately has been
1828 marketesed into SMVP.
1829 Virtual SMP uses the processor's VPEs to implement virtual
1830 processors. In currently available configuration of the 34K processor
1831 this allows for a dual processor. Both processors will share the same
1832 primary caches; each will obtain the half of the TLB for it's own
1833 exclusive use. For a layman this model can be described as similar to
1834 what Intel calls Hyperthreading.

1853 is presenting the available TC's of the core as processors to Linux.
1854 On currently available 34K processors this means a Linux system will

1856 significantly from VSMP and cannot efficiently coexist in the same
