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.
