2182 the price of higher memory consumption. This option is available
2183 only on cnMIPS cores. Note that you will need a suitable Linux

2208 The kernel memory allocator divides physically contiguous memory
2209 blocks into "zones", where each zone is a power of two number of
2210 pages. This option selects the largest power of two that the kernel
2211 keeps in the memory allocator. If you need to allocate very large
2212 blocks of physically contiguous memory, then you may need to
2213 increase this value.
2214
2215 This config option is actually maximum order plus one. For example,
2216 a value of 11 means that the largest free memory block is 2^10 pages.
2217
2218 The page size is not necessarily 4KB. Keep this in mind
2219 when choosing a value for this option.

2853 kexec is a system call that implements the ability to shutdown your
2854 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002855 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002856 you can start any kernel with it, not just Linux.
2857
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002858 The name comes from the similarity to the exec system call.

2861 is properly shutdown, so do not be surprised if this code does not

2909 When this is enabled, the kernel will support use of 64-bit floating
2910 point registers with binaries using the O32 ABI along with the
2911 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2912 32-bit MIPS systems this support is at the cost of increasing the
2913 size and complexity of the compiled FPU emulator. Thus if you are
2914 running a MIPS32 system and know that none of your userland binaries
2915 will require 64-bit floating point, you may wish to reduce the size
2916 of your kernel & potentially improve FP emulation performance by
2917 saying N here.
