1520 Loongson 2F03 and later have fixed these issues and no workarounds
1521 are needed. The workarounds have no significant side effect on them
1522 but may decrease the performance of the system so this option should

1866 This is a kernel model which is known a VSMP but lately has been
1867 marketesed into SMVP.
1868 Virtual SMP uses the processor's VPEs to implement virtual
1869 processors. In currently available configuration of the 34K processor
1870 this allows for a dual processor. Both processors will share the same
1871 primary caches; each will obtain the half of the TLB for it's own
1872 exclusive use. For a layman this model can be described as similar to
1873 what Intel calls Hyperthreading.

1892 is presenting the available TC's of the core as processors to Linux.
1893 On currently available 34K processors this means a Linux system will
1894 see up to 5 processors. The implementation of the SMTC kernel differs
1895 significantly from VSMP and cannot efficiently coexist in the same
1896 kernel binary so the choice between VSMP and SMTC is a compile time
1897 decision.

2358 Find out whether you have a PCI motherboard. PCI is the name of a
2359 bus system, i.e. the way the CPU talks to the other stuff inside
2360 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2361 say Y, otherwise N.

2381 ---help---
2382 The Extended Industry Standard Architecture (EISA) bus was
2383 developed as an open alternative to the IBM MicroChannel bus.
2384
2385 The EISA bus provided some of the features of the IBM MicroChannel
2386 bus while maintaining backward compatibility with cards made for
2387 the older ISA bus. The EISA bus saw limited use between 1988 and
2388 1995 when it was made obsolete by the PCI bus.
2389
2390 Say Y here if you are building a kernel for an EISA-based machine.
2391
2392 Otherwise, say N.
