1294 Please make sure to pick the right CPU type. Linux/MIPS is not
1295 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1296 *not* work on R4000 machines and vice versa. However, since most
1297 of the supported machines have an R4000 (or similar) CPU, R4x00
1298 might be a safe bet. If the resulting kernel does not work,
1299 try to recompile with R3000.

1867 This is a kernel model which is known a VSMP but lately has been

1869 Virtual SMP uses the processor's VPEs to implement virtual
1870 processors. In currently available configuration of the 34K processor
1871 this allows for a dual processor. Both processors will share the same
1872 primary caches; each will obtain the half of the TLB for it's own
1873 exclusive use. For a layman this model can be described as similar to
1874 what Intel calls Hyperthreading.
