| 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 SMTC_IDLE_HOOK_DEBUG | |
| bool "Enable additional debug checks before going into CPU idle loop" | |
| depends on DEBUG_KERNEL && MIPS_MT_SMTC | |
| help | |
| This option enables Enable additional debug checks before going into | |
| CPU idle loop. For details on these checks, see | |
| arch/mips/kernel/smtc.c. This debugging option result in significant | |
| overhead so should be disabled in production kernels. | |
| config KGDB | |

| depends on DEBUG_KERNEL && SYS_SUPPORTS_KGDB | |
| 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. | |

| 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'. | |

| 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. | |
