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. source "init/Kconfig" # Use the generic interrupt handling code in kernel/irq/ source "kernel/Kconfig.freezer" config CMDLINE_BOOL bool "Default bootloader kernel arguments" config CMDLINE string "Kernel command line" depends on CMDLINE_BOOL default "console=ttyS0,57600" 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. config CMDLINE_FORCE bool "Force default kernel command string" depends on CMDLINE_BOOL default n help 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. menu "Processor type and features" source "arch/c6x/platforms/Kconfig" config KERNEL_RAM_BASE_ADDRESS hex "Virtual address of memory base" default 0xe0000000 if SOC_TMS320C6455 default 0xe0000000 if SOC_TMS320C6457 default 0xe0000000 if SOC_TMS320C6472 default 0x80000000 source "mm/Kconfig" source "kernel/Kconfig.preempt" source "kernel/Kconfig.hz" endmenu menu "Executable file formats" source "fs/Kconfig.binfmt" endmenu source "net/Kconfig" source "drivers/Kconfig" source "fs/Kconfig" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig" menu "Kernel hacking" source "lib/Kconfig.debug" config ACCESS_CHECK bool "Check the user pointer address" default y help Usually the pointer transfer from user space is checked to see if its address is in the kernel space.
