942 Some MIPS machines can be configured for either little or big endian
5e83d430 943 byte order. These modes require different kernels and a different
3cb2fccc 944 Linux distribution. In general there is one preferred byteorder for a
5e83d430 945 particular system but some systems are just as commonly used in the
3dde6ad8 946 one or the other endianness.

1441 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1443 Loongson 2F03 and later have fixed these issues and no workarounds
1444 are needed. The workarounds have no significant side effect on them
1445 but may decrease the performance of the system so this option should
1446 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1772 This is a kernel model which is known a VSMP but lately has been

1774 Virtual SMP uses the processor's VPEs to implement virtual
1775 processors. In currently available configuration of the 34K processor
1776 this allows for a dual processor. Both processors will share the same
1777 primary caches; each will obtain the half of the TLB for it's own
1778 exclusive use. For a layman this model can be described as similar to
1779 what Intel calls Hyperthreading.

2387 Select this option if you want to run o32 binaries. These are pure
2388 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2389 existing binaries are in this format.

2398 64-bit binaries using 32-bit quantities for addressing and certain
