| config DEBUG_TLB_SANITY | |
| bool "Debug TLB sanity" | |
| depends on DEBUG_KERNEL | |
| 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 n | |
| 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. | |
