Use this option to have the compiler generate 65 function calls with 32-bit range. This will make the kernel both 66 larger and slower. 67 68 If unsure, say N. 69 70source "init/Kconfig" 71 72# Use the generic interrupt handling code in kernel/irq/ 73 74source "kernel/Kconfig.freezer" 75 76config CMDLINE_BOOL 77 bool "Default bootloader kernel arguments" 78 79config CMDLINE 80 string "Kernel command line" 81 depends on CMDLINE_BOOL 82 default "console=ttyS0,57600" 83 help 84 On some architectures there is currently no way for the boot loader 85 to pass arguments to the kernel.

This option selects the largest power of two that the kernel 113 keeps in the memory allocator. If you need to allocate very large 114 blocks of physically contiguous memory, then you may need to 115 increase this value. 116 117 This config option is actually maximum order plus one. For example, 118 a value of 11 means that the largest free memory block is 2^10 pages. 119 120menu "Processor type and features" 121 122source "arch/c6x/platforms/Kconfig" 123 124config TMS320C6X_CACHES_ON 125 bool "L2 cache support" 126 default y 127 128config KERNEL_RAM_BASE_ADDRESS 129 hex "Virtual address of memory base" 130 default 0xe0000000 if SOC_TMS320C6455 131 default 0xe0000000 if SOC_TMS320C6457 132 default 0xe0000000 if SOC_TMS320C6472 133 default 0x80000000 134 135source "mm/Kconfig" 136 137source "kernel/Kconfig.preempt" 138 139source "kernel/Kconfig.hz" 140source "kernel/time/Kconfig" 141 142endmenu 143 144menu "Executable file formats" 145 146source "fs/Kconfig.binfmt" 147 148endmenu 149 150source "net/Kconfig" 151 152source "drivers/Kconfig" 153 154source "fs/Kconfig" 155 156source "security/Kconfig" 157 158source "crypto/Kconfig" 159 160source "lib/Kconfig" 161 162menu "Kernel hacking" 163 164source "lib/Kconfig.debug" 165 166config ACCESS_CHECK 167 bool "Check the user pointer address" 168 default y 169 help 170 Usually the pointer transfer from user space is checked to see if its 171 address is in the kernel space. 172 173 Say N here to disable that check to improve the performance. 174 175endmenu 176
