| 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. |
| |
| 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. |
