930 Some MIPS machines can be configured for either little or big endian
5e83d430 931 byte order. These modes require different kernels and a different
3cb2fccc 932 Linux distribution. In general there is one preferred byteorder for a
5e83d430 933 particular system but some systems are just as commonly used in the
3dde6ad8 934 one or the other endianness.

1765 This is a kernel model which is known a VSMP but lately has been

1767 Virtual SMP uses the processor's VPEs to implement virtual
1768 processors. In currently available configuration of the 34K processor
1769 this allows for a dual processor. Both processors will share the same
1770 primary caches; each will obtain the half of the TLB for it's own
1771 exclusive use. For a layman this model can be described as similar to
1772 what Intel calls Hyperthreading.

1792 On currently available 34K processors this means a Linux system will
