| 45 | bool "Build a big kernel" |
| 46 | help |
| 47 | The C6X function call instruction has a limited range of +/- 2MiB. |
| 48 | This is sufficient for most kernels, but some kernel configurations |
| 49 | with lots of compiled-in functionality may require a larger range |
| 50 | for function calls. Use this option to have the compiler generate |
| 51 | function calls with 32-bit range. This will make the kernel both |
| 52 | larger and slower. |
| 53 | |
| 54 | If unsure, say N. |

| 66 | On some architectures there is currently no way for the boot loader |
| 67 | to pass arguments to the kernel. For these architectures, you should |
| 68 | supply some command-line options at build time by entering them |

| 82 | help |
| 83 | Say Y if you plan on running a kernel in big-endian mode. |
| 84 | Note that your board must be properly built and your board |
| 85 | port must properly enable any big-endian related features |
| 86 | of your chipset/board/processor. |

| 88 | config FORCE_MAX_ZONEORDER |
| 89 | int "Maximum zone order" |
| 90 | default "13" |
| 91 | help |
| 92 | The kernel memory allocator divides physically contiguous memory |
| 93 | blocks into "zones", where each zone is a power of two number of |
| 94 | pages. This option selects the largest power of two that the kernel |
| 95 | keeps in the memory allocator. If you need to allocate very large |
| 96 | blocks of physically contiguous memory, then you may need to |
| 97 | increase this value. |
| 98 | |
| 99 | This config option is actually maximum order plus one. For example, |
| 100 | a value of 11 means that the largest free memory block is 2^10 pages. |
