1219 Choose this option to build a kernel for release 1 or later of the
1220 MIPS64 architecture. Many modern embedded systems with a 64-bit
1221 MIPS processor are based on a MIPS64 processor. If you know the
1222 specific type of processor in your system, choose those that one
1223 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +00001224 Release 2 of the MIPS64 architecture is available since several
1225 years so chances are you even have a MIPS64 Release 2 processor
1226 in which case you should choose CPU_MIPS64_R2 instead for better
1227 performance.

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.

1816 Virtual SMP uses the processor's VPEs to implement virtual
1817 processors. In currently available configuration of the 34K processor
1818 this allows for a dual processor. Both processors will share the same
1819 primary caches; each will obtain the half of the TLB for it's own
1820 exclusive use. For a layman this model can be described as similar to
1821 what Intel calls Hyperthreading.

2342 The Extended Industry Standard Architecture (EISA) bus was
2343 developed as an open alternative to the IBM MicroChannel bus.
2344
2345 The EISA bus provided some of the features of the IBM MicroChannel
2346 bus while maintaining backward compatibility with cards made for
2347 the older ISA bus. The EISA bus saw limited use between 1988 and
2348 1995 when it was made obsolete by the PCI bus.
