1448 Please make sure to pick the right CPU type. Linux/MIPS is not
1449 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1450 *not* work on R4000 machines and vice versa. However, since most
1451 of the supported machines have an R4000 (or similar) CPU, R4x00
1452 might be a safe bet. If the resulting kernel does not work,
1453 try to recompile with R3000.

1682 benefit is to increase physical addressing equal to or greater

1684 64-bit addressing which in turn makes the PTEs 64-bit in size.

1700 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1701 require workarounds. Without workarounds the system may hang
1702 unexpectedly. For more information please refer to the gas
1703 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1704
1705 Loongson 2F03 and later have fixed these issues and no workarounds
1706 are needed. The workarounds have no significant side effect on them
1707 but may decrease the performance of the system so this option should
1708 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1709 systems.

2297 SmartMIPS is a extension of the MIPS32 architecture aimed at
2298 increased security at both hardware and software level for
2299 smartcards. Enabling this option will allow proper use of the
2300 SmartMIPS instructions by Linux applications. However a kernel with
2301 this option will not work on a MIPS core without SmartMIPS core. If

2617 Generate crash dump after being started by kexec.
2618 This should be normally only set in special crash dump kernels
2619 which are loaded in the main kernel with kexec-tools into
2620 a specially reserved region and then later executed after
2621 a crash by kdump/kexec. The crash dump kernel must be compiled
2622 to a memory address not used by the main kernel or firmware using
2623 PHYSICAL_START.

2642 This kernel feature is useful for number crunching applications
2643 that may need to compute untrusted bytecode during their
2644 execution. By using pipes or other transports made available to
2645 the process as file descriptors supporting the read/write
2646 syscalls, it's possible to isolate those applications in
2647 their own address space using seccomp. Once seccomp is
2648 enabled via /proc/<pid>/seccomp, it cannot be disabled
2649 and the task is only allowed to execute a few safe syscalls
2650 defined by each seccomp mode.

2658 When this is enabled, the kernel will support use of 64-bit floating
2659 point registers with binaries using the O32 ABI along with the
2660 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2661 32-bit MIPS systems this support is at the cost of increasing the
2662 size and complexity of the compiled FPU emulator. Thus if you are
2663 running a MIPS32 system and know that none of your userland binaries
2664 will require 64-bit floating point, you may wish to reduce the size
2665 of your kernel & potentially improve FP emulation performance by
2666 saying N here.
2667
Paul Burton06e2e882014-02-14 17:55:18 +00002668 Although binutils currently supports use of this flag the details
2669 concerning its effect upon the O32 ABI in userland are still being
2670 worked on. In order to avoid userland becoming dependant upon current
2671 behaviour before the details have been finalised, this option should
2672 be considered experimental and only enabled by those working upon
2673 said details.
