1230 Choose this option to build a kernel for release 1 or later of the
1231 MIPS64 architecture. Many modern embedded systems with a 64-bit
1232 MIPS processor are based on a MIPS64 processor. If you know the
1233 specific type of processor in your system, choose those that one
1234 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.
Ralf Baechle1e5f1ca2005-07-12 14:51:22 +00001235 Release 2 of the MIPS64 architecture is available since several
1236 years so chances are you even have a MIPS64 Release 2 processor
1237 in which case you should choose CPU_MIPS64_R2 instead for better
1238 performance.

1262 Please make sure to pick the right CPU type. Linux/MIPS is not
1263 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1264 *not* work on R4000 machines and vice versa. However, since most
1265 of the supported machines have an R4000 (or similar) CPU, R4x00
1266 might be a safe bet. If the resulting kernel does not work,
1267 try to recompile with R3000.

1827 Virtual SMP uses the processor's VPEs to implement virtual
1828 processors. In currently available configuration of the 34K processor
1829 this allows for a dual processor. Both processors will share the same
1830 primary caches; each will obtain the half of the TLB for it's own
1831 exclusive use. For a layman this model can be described as similar to
1832 what Intel calls Hyperthreading.

2284 This kernel feature is useful for number crunching applications
2285 that may need to compute untrusted bytecode during their
2286 execution. By using pipes or other transports made available to
2287 the process as file descriptors supporting the read/write
2288 syscalls, it's possible to isolate those applications in
2289 their own address space using seccomp. Once seccomp is
2290 enabled via /proc/<pid>/seccomp, it cannot be disabled
2291 and the task is only allowed to execute a few safe syscalls
2292 defined by each seccomp mode.
2293

2353 The Extended Industry Standard Architecture (EISA) bus was

2356 The EISA bus provided some of the features of the IBM MicroChannel
2357 bus while maintaining backward compatibility with cards made for
