1394 New Loongson 3 CPU (since Loongson-3A R2, as opposed to Loongson-3A
1395 R1, Loongson-3B R1 and Loongson-3B R2) has many enhancements, such as
1396 FTLB, L1-VCache, EI/DI/Wait/Prefetch instruction, DSP/DSPv2 ASE, User
1397 Local register, Read-Inhibit/Execute-Inhibit, SFB (Store Fill Buffer),
1398 Fast TLB refill support, etc.
1399
1400 This option enable those enhancements which are not probed at run
1401 time. If you want a generic kernel to run on all Loongson 3 machines,
1402 please say 'N' here. If you want a high-performance kernel to run on
1403 new Loongson 3 machines only, please say 'Y' here.

1555 Please make sure to pick the right CPU type. Linux/MIPS is not
1556 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1557 *not* work on R4000 machines and vice versa. However, since most
1558 of the supported machines have an R4000 (or similar) CPU, R4x00
1559 might be a safe bet. If the resulting kernel does not work,

1793 benefit is to increase physical addressing equal to or greater

1795 64-bit addressing which in turn makes the PTEs 64-bit in size.

1811 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1812 require workarounds. Without workarounds the system may hang
1813 unexpectedly. For more information please refer to the gas
1814 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1815
1816 Loongson 2F03 and later have fixed these issues and no workarounds
1817 are needed. The workarounds have no significant side effect on them
1818 but may decrease the performance of the system so this option should
1819 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1820 systems.

3017 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,

3061 The Extended Industry Standard Architecture (EISA) bus was
3062 developed as an open alternative to the IBM MicroChannel bus.
3063
3064 The EISA bus provided some of the features of the IBM MicroChannel
3065 bus while maintaining backward compatibility with cards made for
3066 the older ISA bus. The EISA bus saw limited use between 1988 and
3067 1995 when it was made obsolete by the PCI bus.
3068
3069 Say Y here if you are building a kernel for an EISA-based machine.
