1285 Please make sure to pick the right CPU type. Linux/MIPS is not
1286 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1287 *not* work on R4000 machines and vice versa. However, since most
1288 of the supported machines have an R4000 (or similar) CPU, R4x00
1289 might be a safe bet. If the resulting kernel does not work,
1290 try to recompile with R3000.

1510 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which

1512 unexpectedly. For more information please refer to the gas
1513 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1514
1515 Loongson 2F03 and later have fixed these issues and no workarounds
1516 are needed. The workarounds have no significant side effect on them
1517 but may decrease the performance of the system so this option should
1518 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1519 systems.

1813 The kernel memory allocator divides physically contiguous memory
1814 blocks into "zones", where each zone is a power of two number of
1815 pages. This option selects the largest power of two that the kernel
1816 keeps in the memory allocator. If you need to allocate very large
1817 blocks of physically contiguous memory, then you may need to
1818 increase this value.
1819
1820 This config option is actually maximum order plus one. For example,
1821 a value of 11 means that the largest free memory block is 2^10 pages.
1822
1823 The page size is not necessarily 4KB. Keep this in mind
1824 when choosing a value for this option.

1905 marketesed into SMVP.
1906 Virtual SMP uses the processor's VPEs to implement virtual
1907 processors. In currently available configuration of the 34K processor
1908 this allows for a dual processor. Both processors will share the same
1909 primary caches; each will obtain the half of the TLB for it's own
1910 exclusive use. For a layman this model can be described as similar to
1911 what Intel calls Hyperthreading.

1933 significantly from VSMP and cannot efficiently coexist in the same
