1185 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1355 Loongson 2F03 and later have fixed these issues and no workarounds
1356 are needed. The workarounds have no significant side effect on them
1357 but may decrease the performance of the system so this option should

1651 marketesed into SMVP.
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.

1679 significantly from VSMP and cannot efficiently coexist in the same
