113 config OPENRISC_NO_SPR_SR_DSX
114 bool "use SPR_SR_DSX software emulation" if OR1K_1200
117 SPR_SR_DSX bit is status register bit indicating whether
118 the last exception has happened in delay slot.
120 OpenRISC architecture makes it optional to have it implemented
121 in hardware and the OR1200 does not have it.
123 Say N here if you know that your OpenRISC processor has
124 SPR_SR_DSX bit implemented. Say Y if you are unsure.
127 string "Default kernel command string"
130 On some architectures there is currently no way for the boot loader
131 to pass arguments to the kernel. For these architectures, you should
132 supply some command-line options at build time by entering them

137 config DEBUG_STACKOVERFLOW
138 bool "Check for kernel stack overflow"
141 Make extra checks for space available on stack in some
142 critical functions. This will cause kernel to run a bit slower,
143 but will catch most of kernel stack overruns and exit gracefully.
145 Say Y if you are unsure.
147 config JUMP_UPON_UNHANDLED_EXCEPTION
148 bool "Try to die gracefully"
151 Now this puts kernel into infinite loop after first oops. Till
152 your kernel crashes this doesn't have any influence.
154 Say Y if you are unsure.
156 config OPENRISC_ESR_EXCEPTION_BUG_CHECK
157 bool "Check for possible ESR exception bug"
160 This option enables some checks that might expose some problems
