Use this option to have the compiler generate 50 function calls with 32-bit range. This will make the kernel both 51 larger and slower. 52 53 If unsure, say N. 54 55source "init/Kconfig" 56 57# Use the generic interrupt handling code in kernel/irq/ 58 59source "kernel/Kconfig.freezer" 60 61config CMDLINE_BOOL 62 bool "Default bootloader kernel arguments" 63 64config CMDLINE 65 string "Kernel command line" 66 depends on CMDLINE_BOOL 67 default "console=ttyS0,57600" 68 help 69 On some architectures there is currently no way for the boot loader 70 to pass arguments to the kernel.

This option selects the largest power of two that the kernel 98 keeps in the memory allocator. If you need to allocate very large 99 blocks of physically contiguous memory, then you may need to 100 increase this value. 101 102 This config option is actually maximum order plus one. For example, 103 a value of 11 means that the largest free memory block is 2^10 pages. 104 105menu "Processor type and features" 106 107source "arch/c6x/platforms/Kconfig" 108 109config TMS320C6X_CACHES_ON 110 bool "L2 cache support" 111 default y 112 113config KERNEL_RAM_BASE_ADDRESS 114 hex "Virtual address of memory base" 115 default 0xe0000000 if SOC_TMS320C6455 116 default 0xe0000000 if SOC_TMS320C6457 117 default 0xe0000000 if SOC_TMS320C6472 118 default 0x80000000 119 120source "mm/Kconfig" 121 122source "kernel/Kconfig.preempt" 123 124source "kernel/Kconfig.hz" 125 126endmenu 127 128menu "Executable file formats" 129 130source "fs/Kconfig.binfmt" 131 132endmenu 133 134source "net/Kconfig" 135 136source "drivers/Kconfig" 137 138source "fs/Kconfig" 139 140source "security/Kconfig" 141 142source "crypto/Kconfig" 143 144source "lib/Kconfig" 145 146menu "Kernel hacking" 147 148source "lib/Kconfig.debug" 149 150config ACCESS_CHECK 151 bool "Check the user pointer address" 152 default y 153 help 154 Usually the pointer transfer from user space is checked to see if its 155 address is in the kernel space. 156 157 Say N here to disable that check to improve the performance. 158 159endmenu 160
