| 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. |
