1826 This is a kernel model which is known a VSMP but lately has been
1827 marketesed into SMVP.
1828 Virtual SMP uses the processor's VPEs to implement virtual
1829 processors. In currently available configuration of the 34K processor
1830 this allows for a dual processor. Both processors will share the same
1831 primary caches; each will obtain the half of the TLB for it's own
1832 exclusive use. For a layman this model can be described as similar to
1833 what Intel calls Hyperthreading.

1853 On currently available 34K processors this means a Linux system will
