1332 Please make sure to pick the right CPU type. Linux/MIPS is not
1333 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1334 *not* work on R4000 machines and vice versa. However, since most
1335 of the supported machines have an R4000 (or similar) CPU, R4x00
1336 might be a safe bet. If the resulting kernel does not work,
1337 try to recompile with R3000.

1568 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1569 require workarounds. Without workarounds the system may hang
1570 unexpectedly. For more information please refer to the gas
1571 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1572
1573 Loongson 2F03 and later have fixed these issues and no workarounds
1574 are needed. The workarounds have no significant side effect on them
1575 but may decrease the performance of the system so this option should
1576 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1577 systems.

1861 The kernel memory allocator divides physically contiguous memory
1862 blocks into "zones", where each zone is a power of two number of
1863 pages. This option selects the largest power of two that the kernel
1864 keeps in the memory allocator. If you need to allocate very large
1865 blocks of physically contiguous memory, then you may need to
1866 increase this value.
1867
1868 This config option is actually maximum order plus one. For example,
1869 a value of 11 means that the largest free memory block is 2^10 pages.
1870
1871 The page size is not necessarily 4KB. Keep this in mind
1872 when choosing a value for this option.

Ralf Baechle25f12b32010-09-16 11:40:41 +01001943 This is a kernel model which is known a VSMP but lately has been
1944 marketesed into SMVP.
1945 Virtual SMP uses the processor's VPEs to implement virtual
1946 processors. In currently available configuration of the 34K processor
1947 this allows for a dual processor. Both processors will share the same
1948 primary caches; each will obtain the half of the TLB for it's own
1949 exclusive use. For a layman this model can be described as similar to
1950 what Intel calls Hyperthreading.

1972 significantly from VSMP and cannot efficiently coexist in the same
