   3config DEBUG_TLB_SANITY
   4        bool "Debug TLB sanity"
   5        depends on DEBUG_KERNEL && MMU
   6        help
   7          Enable this to turn on TLB sanity check on each entry to userspace.
   8          This check can spot missing TLB invalidation/wrong PTE permissions/
   9          premature page freeing.
  10
  11          If unsure, say N.

  13config LD_NO_RELAX
  14        bool "Disable linker relaxation"
  15        default y
  16        help
  17          Enable this function to disable link-time optimizations.
  18          The default linker behavior is to combine identical literal
  19          values to reduce code size and remove unnecessary overhead from
  20          assembler-generated 'longcall' sequences.
  21          Enabling this option improves the link time but increases the
  22          code size, and possibly execution time.

  24config S32C1I_SELFTEST
  25        bool "Perform S32C1I instruction self-test at boot"
  26        default y
  27        help
  28          Enable this option to test S32C1I instruction behavior at boot.
  29          Correct operation of this instruction requires some cooperation from hardware
  30          external to the processor (such as bus bridge, bus fabric, or memory controller).
  31          It is easy to make wrong hardware configuration, this test should catch it early.
  32
  33          Say 'N' on stable hardware.
  34
  35config PRINT_STACK_DEPTH
  36        int "Stack depth to print" if DEBUG_KERNEL
  37        default 64
  38        help
  39          This option allows you to set the stack depth that the kernel
  40          prints in stack traces.
