1233 Please make sure to pick the right CPU type. Linux/MIPS is not
1234 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1235 *not* work on R4000 machines and vice versa. However, since most
1236 of the supported machines have an R4000 (or similar) CPU, R4x00
1237 might be a safe bet. If the resulting kernel does not work,
1238 try to recompile with R3000.

1458 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1459 require workarounds. Without workarounds the system may hang
1460 unexpectedly. For more information please refer to the gas
1461 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1462
1463 Loongson 2F03 and later have fixed these issues and no workarounds
1464 are needed. The workarounds have no significant side effect on them
1465 but may decrease the performance of the system so this option should
1466 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1467 systems.

1855 marketesed into SMVP.
1856 Virtual SMP uses the processor's VPEs to implement virtual
1857 processors. In currently available configuration of the 34K processor
1858 this allows for a dual processor. Both processors will share the same
1859 primary caches; each will obtain the half of the TLB for it's own
1860 exclusive use. For a layman this model can be described as similar to
1861 what Intel calls Hyperthreading.

Linus Torvalds1da177e2005-04-16 15:20:36 -07002131 This enables support for systems with more than one CPU. If you have
2132 a system with only one CPU, like most personal computers, say N. If
2133 you have a system with more than one CPU, say Y.
2134
2135 If you say N here, the kernel will run on single and multiprocessor
2136 machines, but will use only one CPU of a multiprocessor machine. If
2137 you say Y here, the kernel will run on many, but not all,
2138 singleprocessor machines. On a singleprocessor machine, the kernel
2139 will run faster if you say N here.
2140
2141 People using multiprocessor machines who say Y here should also say
2142 Y to "Enhanced Real Time Clock Support", below.
