932 Some MIPS machines can be configured for either little or big endian
5e83d430 933 byte order. These modes require different kernels and a different
3cb2fccc 934 Linux distribution. In general there is one preferred byteorder for a
5e83d430 935 particular system but some systems are just as commonly used in the
3dde6ad8 936 one or the other endianness.

1767 This is a kernel model which is known a VSMP but lately has been

1769 Virtual SMP uses the processor's VPEs to implement virtual
1770 processors. In currently available configuration of the 34K processor
1771 this allows for a dual processor. Both processors will share the same
1772 primary caches; each will obtain the half of the TLB for it's own
1773 exclusive use. For a layman this model can be described as similar to
1774 what Intel calls Hyperthreading.

1794 On currently available 34K processors this means a Linux system will
