1251 Please make sure to pick the right CPU type. Linux/MIPS is not
1252 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1253 *not* work on R4000 machines and vice versa. However, since most
1254 of the supported machines have an R4000 (or similar) CPU, R4x00
1255 might be a safe bet. If the resulting kernel does not work,
1256 try to recompile with R3000.

1476 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1477 require workarounds. Without workarounds the system may hang
1478 unexpectedly. For more information please refer to the gas
1479 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1480
1481 Loongson 2F03 and later have fixed these issues and no workarounds
1482 are needed. The workarounds have no significant side effect on them
1483 but may decrease the performance of the system so this option should
1484 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1485 systems.

1872 marketesed into SMVP.
1873 Virtual SMP uses the processor's VPEs to implement virtual
1874 processors. In currently available configuration of the 34K processor
1875 this allows for a dual processor. Both processors will share the same
1876 primary caches; each will obtain the half of the TLB for it's own
1877 exclusive use. For a layman this model can be described as similar to
1878 what Intel calls Hyperthreading.

2149 a system with only one CPU, like most personal computers, say N. If
2150 you have a system with more than one CPU, say Y.

2152 If you say N here, the kernel will run on single and multiprocessor
2153 machines, but will use only one CPU of a multiprocessor machine. If
2154 you say Y here, the kernel will run on many, but not all,
