1822 This is a kernel model which is known a VSMP but lately has been
1823 marketesed into SMVP.
1824 Virtual SMP uses the processor's VPEs to implement virtual
1825 processors. In currently available configuration of the 34K processor
1826 this allows for a dual processor. Both processors will share the same
1827 primary caches; each will obtain the half of the TLB for it's own
1828 exclusive use. For a layman this model can be described as similar to
1829 what Intel calls Hyperthreading.

1849 On currently available 34K processors this means a Linux system will
