config OPENRISC_NO_SPR_SR_DSX

	bool "use SPR_SR_DSX software emulation" if OR1K_1200

	default y

	help

	  SPR_SR_DSX bit is status register bit indicating whether

	  the last exception has happened in delay slot.

	  OpenRISC architecture makes it optional to have it implemented

	  in hardware and the OR1200 does not have it.

	  Say N here if you know that your OpenRISC processor has

	  SPR_SR_DSX bit implemented. Say Y if you are unsure.

config CMDLINE

        string "Default kernel command string"

        default ""

        help

          On some architectures there is currently no way for the boot loader

          to pass arguments to the kernel. For these architectures, you should

          supply some command-line options at build time by entering them

          here.

menu "Debugging options"

config DEBUG_STACKOVERFLOW

	bool "Check for kernel stack overflow"

	default y

	help

	  Make extra checks for space avaliable on stack in some

          critical functions. This will cause kernel to run a bit slower,

	  but will catch most of kernel stack overruns and exit gracefuly.

	  Say Y if you are unsure.

config JUMP_UPON_UNHANDLED_EXCEPTION

	bool "Try to die gracefully"

	default y

	help

	  Now this puts kernel into infinite loop after first oops. Till

	  your kernel crashes this doesn't have any influence.

	  Say Y if you are unsure.

config OPENRISC_EXCEPTION_DEBUG

	bool "Print processor state at each exception"

	default n

	help

	  This option will make your kernel unusable for all but kernel

	  debugging.

	  Say N if you are unsure.

config OPENRISC_ESR_EXCEPTION_BUG_CHECK

	bool "Check for possible ESR exception bug"

	default n

	help

	  This option enables some checks that might expose some problems

          in kernel.

	  Say N if you are unsure.
