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.

1777 This is a kernel model which is known a VSMP but lately has been

1779 Virtual SMP uses the processor's VPEs to implement virtual
1780 processors. In currently available configuration of the 34K processor
1781 this allows for a dual processor. Both processors will share the same
1782 primary caches; each will obtain the half of the TLB for it's own
1783 exclusive use. For a layman this model can be described as similar to
1784 what Intel calls Hyperthreading.

1804 On currently available 34K processors this means a Linux system will
