1865 This is a kernel model which is known a VSMP but lately has been
1866 marketesed into SMVP.
1867 Virtual SMP uses the processor's VPEs to implement virtual
1868 processors. In currently available configuration of the 34K processor
1869 this allows for a dual processor. Both processors will share the same
1870 primary caches; each will obtain the half of the TLB for it's own
1871 exclusive use. For a layman this model can be described as similar to
1872 what Intel calls Hyperthreading.

RB
1891 is presenting the available TC's of the core as processors to Linux.
1892 On currently available 34K processors this means a Linux system will
1893 see up to 5 processors. The implementation of the SMTC kernel differs
1894 significantly from VSMP and cannot efficiently coexist in the same
1895 kernel binary so the choice between VSMP and SMTC is a compile time
1896 decision.

2362 Find out whether you have a PCI motherboard. PCI is the name of a
2363 bus system, i.e. the way the CPU talks to the other stuff inside
2364 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2365 say Y, otherwise N.

2385 ---help---
2386 The Extended Industry Standard Architecture (EISA) bus was
2387 developed as an open alternative to the IBM MicroChannel bus.
2388
2389 The EISA bus provided some of the features of the IBM MicroChannel
2390 bus while maintaining backward compatibility with cards made for
2391 the older ISA bus. The EISA bus saw limited use between 1988 and
2392 1995 when it was made obsolete by the PCI bus.
2393
2394 Say Y here if you are building a kernel for an EISA-based machine.
2395
2396 Otherwise, say N.
