 | config CROSSCOMPILE | 
 | 	bool "Are you using a crosscompiler" | 
 | 	help | 
 | 	  Say Y here if you are compiling the kernel on a different | 
 | 	  architecture than the one it is intended to run on.  This is just a | 
 | 	  convenience option which will select the appropriate value for | 
 | 	  the CROSS_COMPILE make variable which otherwise has to be passed on | 
 | 	  the command line from mips-linux-, mipsel-linux-, mips64-linux- and | 
 | 	  mips64el-linux- as appropriate for a particular kernel configuration. | 
 | 	  You will have to pass the value for CROSS_COMPILE manually if the | 
 | 	  name prefix for your tools is different. | 
 |  | 
 | config CMDLINE | 
 | 	string "Default kernel command string" | 
 | 	default "" | 
 | 	help | 
 |           On some platforms, there is currently no way for the boot loader to | 
 |           pass arguments to the kernel. For these platforms, you can supply | 
 |           some command-line options at build time by entering them here.  In | 
 |           other cases you can specify kernel args so that you don't have | 
 | 	  to set them up in board prom initialization routines. | 
 |  | 
 | config DEBUG_STACK_USAGE | 
 | 	bool "Enable stack utilization instrumentation" | 
 | 	depends on DEBUG_KERNEL | 
 | 	help | 
 | 	  Enables the display of the minimum amount of free stack which each | 
 | 	  task has ever had available in the sysrq-T and sysrq-P debug output. | 
 |  | 
 | 	  This option will slow down process creation somewhat. | 
 |  | 
 | config KGDB | 
 | 	bool "Remote GDB kernel debugging" | 
 | 	depends on DEBUG_KERNEL | 
 | 	select DEBUG_INFO | 
 | 	help | 
 | 	  If you say Y here, it will be possible to remotely debug the MIPS | 
 | 	  kernel using gdb. This enlarges your kernel image disk size by | 
 | 	  several megabytes and requires a machine with more than 16 MB, | 
 | 	  better 32 MB RAM to avoid excessive linking time. This is only | 
 | 	  useful for kernel hackers. If unsure, say N. | 
 |  | 
 | config GDB_CONSOLE | 
 | 	bool "Console output to GDB" | 
 | 	depends on KGDB | 
 | 	help | 
 | 	  If you are using GDB for remote debugging over a serial port and | 
 | 	  would like kernel messages to be formatted into GDB $O packets so | 
 | 	  that GDB prints them as program output, say 'Y'. | 
 |  | 
 | config SB1XXX_CORELIS | 
 | 	bool "Corelis Debugger" | 
 | 	depends on SIBYTE_SB1xxx_SOC | 
 | 	select DEBUG_INFO | 
 | 	help | 
 | 	  Select compile flags that produce code that can be processed by the | 
 | 	  Corelis mksym utility and UDB Emulator. | 
 |  | 
 | config RUNTIME_DEBUG | 
 | 	bool "Enable run-time debugging" | 
 | 	depends on DEBUG_KERNEL | 
 | 	help | 
 | 	  If you say Y here, some debugging macros will do run-time checking. | 
 | 	  If you say N here, those macros will mostly turn to no-ops.  See | 
 | 	  include/asm-mips/debug.h for debuging macros. | 
 | 	  If unsure, say N. | 
 |  | 
 | config MIPS_UNCACHED | 
 | 	bool "Run uncached" | 
 | 	depends on DEBUG_KERNEL && !SMP && !SGI_IP27 | 
 | 	help | 
 | 	  If you say Y here there kernel will disable all CPU caches.  This will | 
 | 	  reduce the system's performance dramatically but can help finding | 
 | 	  otherwise hard to track bugs.  It can also useful if you're doing | 
 | 	  hardware debugging with a logic analyzer and need to see all traffic | 
 | 	  on the bus. |
