1267 Please make sure to pick the right CPU type. Linux/MIPS is not
1268 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1269 *not* work on R4000 machines and vice versa. However, since most
1270 of the supported machines have an R4000 (or similar) CPU, R4x00
1271 might be a safe bet. If the resulting kernel does not work,
1272 try to recompile with R3000.

1831 marketesed into SMVP.
1832 Virtual SMP uses the processor's VPEs to implement virtual
1833 processors. In currently available configuration of the 34K processor
1834 this allows for a dual processor. Both processors will share the same
1835 primary caches; each will obtain the half of the TLB for it's own
1836 exclusive use. For a layman this model can be described as similar to
1837 what Intel calls Hyperthreading.

1906 To support multiple TC microthreads acting as "CPUs" within
1907 a VPE, VPE-wide interrupt mask bits must be specially manipulated
1908 during interrupt handling. To support legacy drivers and interrupt
1909 controller management code, SMTC has a "backstop" to track and
1910 if necessary restore the interrupt mask. This has some performance

2279 This kernel feature is useful for number crunching applications
2280 that may need to compute untrusted bytecode during their
2281 execution. By using pipes or other transports made available to
2282 the process as file descriptors supporting the read/write
2283 syscalls, it's possible to isolate those applications in
2284 their own address space using seccomp. Once seccomp is
2285 enabled via /proc/<pid>/seccomp, it cannot be disabled
2286 and the task is only allowed to execute a few safe syscalls
2287 defined by each seccomp mode.
2288
2289 If unsure, say Y. Only embedded should say N here.

2348 The Extended Industry Standard Architecture (EISA) bus was
2349 developed as an open alternative to the IBM MicroChannel bus.
2350
2351 The EISA bus provided some of the features of the IBM MicroChannel
2352 bus while maintaining backward compatibility with cards made for
2353 the older ISA bus. The EISA bus saw limited use between 1988 and
2354 1995 when it was made obsolete by the PCI bus.
