1227 Choose this option to build a kernel for release 1 or later of the
1228 MIPS64 architecture. Many modern embedded systems with a 64-bit
1229 MIPS processor are based on a MIPS64 processor. If you know the
1230 specific type of processor in your system, choose those that one
1231 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +00001232 Release 2 of the MIPS64 architecture is available since several
1233 years so chances are you even have a MIPS64 Release 2 processor
1234 in which case you should choose CPU_MIPS64_R2 instead for better
1235 performance.

1259 Please make sure to pick the right CPU type. Linux/MIPS is not
1260 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1261 *not* work on R4000 machines and vice versa. However, since most
1262 of the supported machines have an R4000 (or similar) CPU, R4x00
1263 might be a safe bet. If the resulting kernel does not work,
1264 try to recompile with R3000.

1824 Virtual SMP uses the processor's VPEs to implement virtual
1825 processors. In currently available configuration of the 34K processor
1826 this allows for a dual processor. Both processors will share the same
1827 primary caches; each will obtain the half of the TLB for it's own
1828 exclusive use. For a layman this model can be described as similar to
1829 what Intel calls Hyperthreading.

2281 This kernel feature is useful for number crunching applications
2282 that may need to compute untrusted bytecode during their
2283 execution. By using pipes or other transports made available to
2284 the process as file descriptors supporting the read/write
2285 syscalls, it's possible to isolate those applications in
2286 their own address space using seccomp. Once seccomp is
2287 enabled via /proc/<pid>/seccomp, it cannot be disabled
2288 and the task is only allowed to execute a few safe syscalls
2289 defined by each seccomp mode.

2350 The Extended Industry Standard Architecture (EISA) bus was
2351 developed as an open alternative to the IBM MicroChannel bus.
2352
2353 The EISA bus provided some of the features of the IBM MicroChannel
2354 bus while maintaining backward compatibility with cards made for
2355 the older ISA bus. The EISA bus saw limited use between 1988 and
2356 1995 when it was made obsolete by the PCI bus.
