938 Some MIPS machines can be configured for either little or big endian
5e83d430 939 byte order. These modes require different kernels and a different
3cb2fccc 940 Linux distribution. In general there is one preferred byteorder for a
5e83d430 941 particular system but some systems are just as commonly used in the
3dde6ad8 942 one or the other endianness.

1444 Loongson 2F03 and later have fixed these issues and no workarounds
1445 are needed. The workarounds have no significant side effect on them

1773 This is a kernel model which is known a VSMP but lately has been

1775 Virtual SMP uses the processor's VPEs to implement virtual
1776 processors. In currently available configuration of the 34K processor
1777 this allows for a dual processor. Both processors will share the same
1778 primary caches; each will obtain the half of the TLB for it's own
1779 exclusive use. For a layman this model can be described as similar to
1780 what Intel calls Hyperthreading.

1800 On currently available 34K processors this means a Linux system will

2388 Select this option if you want to run o32 binaries. These are pure
2389 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2390 existing binaries are in this format.

2399 64-bit binaries using 32-bit quantities for addressing and certain
2400 data that would normally be 64-bit. They are used in special
2401 cases.
