- menu "Kernel hacking"
- source "lib/Kconfig.debug"
- 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.
