config TRACE_IRQFLAGS_SUPPORT

        bool

        default y

source "lib/Kconfig.debug"

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 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

        bool "Remote GDB kernel debugging"

        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.

config SYS_SUPPORTS_KGDB

        bool

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.
