1905 This is a kernel model which is known a VSMP but lately has been
1906 marketesed into SMVP.
1907 Virtual SMP uses the processor's VPEs to implement virtual
1908 processors. In currently available configuration of the 34K processor
1909 this allows for a dual processor. Both processors will share the same
1910 primary caches; each will obtain the half of the TLB for it's own
1911 exclusive use. For a layman this model can be described as similar to
1912 what Intel calls Hyperthreading.

1931 is presenting the available TC's of the core as processors to Linux.
1932 On currently available 34K processors this means a Linux system will
1933 see up to 5 processors. The implementation of the SMTC kernel differs
1934 significantly from VSMP and cannot efficiently coexist in the same
1935 kernel binary so the choice between VSMP and SMTC is a compile time
1936 decision.

2340 initially work for you. It may help to enable device hotplugging
2341 support. As of this writing the exact hardware interface is
2342 strongly in flux, so no good recommendation can be made.

2349 This kernel feature is useful for number crunching applications
2350 that may need to compute untrusted bytecode during their
2351 execution. By using pipes or other transports made available to
2352 the process as file descriptors supporting the read/write
2353 syscalls, it's possible to isolate those applications in
2354 their own address space using seccomp. Once seccomp is
2355 enabled via /proc/<pid>/seccomp, it cannot be disabled
2356 and the task is only allowed to execute a few safe syscalls
2357 defined by each seccomp mode.
2358
2359 If unsure, say Y. Only embedded should say N here.

2423 The Extended Industry Standard Architecture (EISA) bus was
2424 developed as an open alternative to the IBM MicroChannel bus.
2425
2426 The EISA bus provided some of the features of the IBM MicroChannel
2427 bus while maintaining backward compatibility with cards made for
2428 the older ISA bus. The EISA bus saw limited use between 1988 and
2429 1995 when it was made obsolete by the PCI bus.
