1196 Please make sure to pick the right CPU type. Linux/MIPS is not
1197 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1198 *not* work on R4000 machines and vice versa. However, since most
1199 of the supported machines have an R4000 (or similar) CPU, R4x00
1200 might be a safe bet. If the resulting kernel does not work,

1414 require workarounds. Without workarounds the system may hang
1415 unexpectedly. For more information please refer to the gas
1416 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1418 Loongson 2F03 and later have fixed these issues and no workarounds
1419 are needed. The workarounds have no significant side effect on them
1420 but may decrease the performance of the system so this option should
1421 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1725 This is a kernel model which is known a VSMP but lately has been

1727 Virtual SMP uses the processor's VPEs to implement virtual
1728 processors. In currently available configuration of the 34K processor
1729 this allows for a dual processor. Both processors will share the same
1730 primary caches; each will obtain the half of the TLB for it's own
1731 exclusive use. For a layman this model can be described as similar to
1732 what Intel calls Hyperthreading.

1751 is presenting the available TC's of the core as processors to Linux.
1752 On currently available 34K processors this means a Linux system will
1753 see up to 5 processors. The implementation of the SMTC kernel differs
1754 significantly from VSMP and cannot efficiently coexist in the same
1755 kernel binary so the choice between VSMP and SMTC is a compile time

1882 SmartMIPS is a extension of the MIPS32 architecture aimed at
1883 increased security at both hardware and software level for
1884 smartcards. Enabling this option will allow proper use of the
1885 SmartMIPS instructions by Linux applications. However a kernel with
1886 this option will not work on a MIPS core without SmartMIPS core. If
1887 you don't know you probably don't have SmartMIPS and should say N
1888 here.
