1199 Please make sure to pick the right CPU type. Linux/MIPS is not
1200 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1201 *not* work on R4000 machines and vice versa. However, since most
1202 of the supported machines have an R4000 (or similar) CPU, R4x00
1203 might be a safe bet. If the resulting kernel does not work,

1420
1421 Loongson 2F03 and later have fixed these issues and no workarounds
1422 are needed. The workarounds have no significant side effect on them
1423 but may decrease the performance of the system so this option should
1424 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1425 systems.

1752 Virtual SMP uses the processor's VPEs to implement virtual
1753 processors. In currently available configuration of the 34K processor
1754 this allows for a dual processor. Both processors will share the same
1755 primary caches; each will obtain the half of the TLB for it's own
1756 exclusive use. For a layman this model can be described as similar to
1757 what Intel calls Hyperthreading.
