config C6X_BIG_KERNEL |
|
bool "Build a big kernel" |
|
help |
|
The C6X function call instruction has a limited range of +/- 2MiB. |
|
This is sufficient for most kernels, but some kernel configurations |
|
with lots of compiled-in functionality may require a larger range |
|
for function calls. Use this option to have the compiler generate |
|
function calls with 32-bit range. This will make the kernel both |
|
larger and slower. |
|
|
|
If unsure, say N. |

help |
|
On some architectures there is currently no way for the boot loader |
|
to pass arguments to the kernel. For these architectures, you should |
|
supply some command-line options at build time by entering them |
|
here. |

Set this to have arguments from the default kernel command string |
|
override those passed by the boot loader. |

config CPU_BIG_ENDIAN |
|
bool "Build big-endian kernel" |
|
default n |
|
help |
|
Say Y if you plan on running a kernel in big-endian mode. |
|
Note that your board must be properly built and your board |
|
port must properly enable any big-endian related features |
|
of your chipset/board/processor. |

config FORCE_MAX_ZONEORDER |
|
int "Maximum zone order" |
|
default "13" |
|
help |
|
The kernel memory allocator divides physically contiguous memory |
|
blocks into "zones", where each zone is a power of two number of |
|
pages. This option selects the largest power of two that the kernel |
|
keeps in the memory allocator. If you need to allocate very large |
|
blocks of physically contiguous memory, then you may need to |
|
increase this value. |
|
|
|
This config option is actually maximum order plus one. For example, |
|
a value of 11 means that the largest free memory block is 2^10 pages. |
