+config DEBUG_TLB_SANITY
+ bool "Debug TLB sanity"
+ depends on DEBUG_KERNEL && MMU
+ help
+ Enable this to turn on TLB sanity check on each entry to userspace.
+ This check can spot missing TLB invalidation/wrong PTE permissions/
+ premature page freeing.
+
+ If unsure, say N.
+
+config LD_NO_RELAX
+ bool "Disable linker relaxation"
+ default y
+ help
+ Enable this function to disable link-time optimizations.
+ The default linker behavior is to combine identical literal
+ values to reduce code size and remove unnecessary overhead from
+ assembler-generated 'longcall' sequences.
+ Enabling this option improves the link time but increases the
+ code size, and possibly execution time.
+
+config S32C1I_SELFTEST
+ bool "Perform S32C1I instruction self-test at boot"
+ default y
+ help
+ Enable this option to test S32C1I instruction behavior at boot.
+ Correct operation of this instruction requires some cooperation from hardware
+ external to the processor (such as bus bridge, bus fabric, or memory controller).
+ It is easy to make wrong hardware configuration, this test should catch it early.
+
+ Say 'N' on stable hardware.
+
+config PRINT_STACK_DEPTH
+ int "Stack depth to print" if DEBUG_KERNEL
+ default 64
+ help
+ This option allows you to set the stack depth that the kernel
+ prints in stack traces.
+
+config PRINT_USER_CODE_ON_UNHANDLED_EXCEPTION
+ bool "Dump user code around unhandled exception address"
+ help
+ Enable this option to display user code around PC of the unhandled
+ exception (starting at address aligned on 16 byte boundary).
+ This may simplify finding faulting code in the absence of other
+ debug facilities.
