1359 The Loongson 2F processor implements the MIPS III instruction set
1360 with many extensions.
1361
1362 Loongson2F have built-in DDR2 and PCIX controller. The PCIX controller
1363 have a similar programming interface with FPGA northbridge used in
1364 Loongson2E.

1481 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1483 of the supported machines have an R4000 (or similar) CPU, R4x00
1484 might be a safe bet. If the resulting kernel does not work,

1713 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1714 benefit is to increase physical addressing equal to or greater

1716 64-bit addressing which in turn makes the PTEs 64-bit in size.

1732 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1733 require workarounds. Without workarounds the system may hang
1734 unexpectedly. For more information please refer to the gas
1735 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1736
1737 Loongson 2F03 and later have fixed these issues and no workarounds
1738 are needed. The workarounds have no significant side effect on them
1739 but may decrease the performance of the system so this option should
1740 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1741 systems.

2702 When this is enabled, the kernel will support use of 64-bit floating
2703 point registers with binaries using the O32 ABI along with the
2704 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2705 32-bit MIPS systems this support is at the cost of increasing the
2706 size and complexity of the compiled FPU emulator. Thus if you are
2707 running a MIPS32 system and know that none of your userland binaries
2708 will require 64-bit floating point, you may wish to reduce the size
2709 of your kernel & potentially improve FP emulation performance by
2710 saying N here.

2714 worked on. In order to avoid userland becoming dependant upon current
2715 behaviour before the details have been finalised, this option should
2716 be considered experimental and only enabled by those working upon
2717 said details.
