| 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. | |
