1236 Choose this option to build a kernel for release 1 or later of the
1237 MIPS64 architecture. Many modern embedded systems with a 64-bit

Ralf Baechle1e5f1ca2005-07-12 14:51:22 +00001241 Release 2 of the MIPS64 architecture is available since several

1268 Please make sure to pick the right CPU type. Linux/MIPS is not
1269 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1270 *not* work on R4000 machines and vice versa. However, since most
1271 of the supported machines have an R4000 (or similar) CPU, R4x00
1272 might be a safe bet. If the resulting kernel does not work,
1273 try to recompile with R3000.

1833 Virtual SMP uses the processor's VPEs to implement virtual
1834 processors. In currently available configuration of the 34K processor
1835 this allows for a dual processor. Both processors will share the same
1836 primary caches; each will obtain the half of the TLB for it's own
1837 exclusive use. For a layman this model can be described as similar to
1838 what Intel calls Hyperthreading.

2290 This kernel feature is useful for number crunching applications
2291 that may need to compute untrusted bytecode during their
2292 execution. By using pipes or other transports made available to
2293 the process as file descriptors supporting the read/write
2294 syscalls, it's possible to isolate those applications in
2295 their own address space using seccomp. Once seccomp is
2296 enabled via /proc/<pid>/seccomp, it cannot be disabled
2297 and the task is only allowed to execute a few safe syscalls
2298 defined by each seccomp mode.

2359 The Extended Industry Standard Architecture (EISA) bus was
2360 developed as an open alternative to the IBM MicroChannel bus.

2362 The EISA bus provided some of the features of the IBM MicroChannel
2363 bus while maintaining backward compatibility with cards made for
2364 the older ISA bus. The EISA bus saw limited use between 1988 and
2365 1995 when it was made obsolete by the PCI bus.
