Use this option to have the compiler generate 49 function calls with 32-bit range. This will make the kernel both 50 larger and slower. 51 52 If unsure, say N. 53 54source "init/Kconfig" 55 56# Use the generic interrupt handling code in kernel/irq/ 57 58source "kernel/Kconfig.freezer" 59 60config CMDLINE_BOOL 61 bool "Default bootloader kernel arguments" 62 63config CMDLINE 64 string "Kernel command line" 65 depends on CMDLINE_BOOL 66 default "console=ttyS0,57600" 67 help 68 On some architectures there is currently no way for the boot loader 69 to pass arguments to the kernel.

This option selects the largest power of two that the kernel 97 keeps in the memory allocator. If you need to allocate very large 98 blocks of physically contiguous memory, then you may need to 99 increase this value. 100 101 This config option is actually maximum order plus one. For example, 102 a value of 11 means that the largest free memory block is 2^10 pages. 103 104menu "Processor type and features" 105 106source "arch/c6x/platforms/Kconfig" 107 108config KERNEL_RAM_BASE_ADDRESS 109 hex "Virtual address of memory base" 110 default 0xe0000000 if SOC_TMS320C6455 111 default 0xe0000000 if SOC_TMS320C6457 112 default 0xe0000000 if SOC_TMS320C6472 113 default 0x80000000 114 115source "mm/Kconfig" 116 117source "kernel/Kconfig.preempt" 118 119source "kernel/Kconfig.hz" 120 121endmenu 122 123menu "Executable file formats" 124 125source "fs/Kconfig.binfmt" 126 127endmenu 128 129source "net/Kconfig" 130 131source "drivers/Kconfig" 132 133source "fs/Kconfig" 134 135source "security/Kconfig" 136 137source "crypto/Kconfig" 138 139source "lib/Kconfig" 140 141menu "Kernel hacking" 142 143source "lib/Kconfig.debug" 144 145config ACCESS_CHECK 146 bool "Check the user pointer address" 147 default y 148 help 149 Usually the pointer transfer from user space is checked to see if its 150 address is in the kernel space. 151 152 Say N here to disable that check to improve the performance. 153 154endmenu 155
