Ralf Baechle1e5f1ca2005-07-12 14:51:22 +00001242 Release 2 of the MIPS64 architecture is available since several

1269 Please make sure to pick the right CPU type. Linux/MIPS is not
1270 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1271 *not* work on R4000 machines and vice versa. However, since most
1272 of the supported machines have an R4000 (or similar) CPU, R4x00
1273 might be a safe bet. If the resulting kernel does not work,
1274 try to recompile with R3000.

1834 Virtual SMP uses the processor's VPEs to implement virtual
1835 processors. In currently available configuration of the 34K processor
1836 this allows for a dual processor. Both processors will share the same
1837 primary caches; each will obtain the half of the TLB for it's own
1838 exclusive use. For a layman this model can be described as similar to
1839 what Intel calls Hyperthreading.

2291 This kernel feature is useful for number crunching applications
2292 that may need to compute untrusted bytecode during their
2293 execution. By using pipes or other transports made available to
2294 the process as file descriptors supporting the read/write
2295 syscalls, it's possible to isolate those applications in
2296 their own address space using seccomp. Once seccomp is
2297 enabled via /proc/<pid>/seccomp, it cannot be disabled
2298 and the task is only allowed to execute a few safe syscalls
2299 defined by each seccomp mode.

2360 The Extended Industry Standard Architecture (EISA) bus was

2363 The EISA bus provided some of the features of the IBM MicroChannel
2364 bus while maintaining backward compatibility with cards made for
