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

1447 Loongson 2F03 and later have fixed these issues and no workarounds

1776 This is a kernel model which is known a VSMP but lately has been

1778 Virtual SMP uses the processor's VPEs to implement virtual
1779 processors. In currently available configuration of the 34K processor
1780 this allows for a dual processor. Both processors will share the same
1781 primary caches; each will obtain the half of the TLB for it's own
1782 exclusive use. For a layman this model can be described as similar to
1783 what Intel calls Hyperthreading.

1803 On currently available 34K processors this means a Linux system will

2391 Select this option if you want to run o32 binaries. These are pure
2392 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2393 existing binaries are in this format.

2401 Select this option if you want to run n32 binaries. These are
2402 64-bit binaries using 32-bit quantities for addressing and certain
