CONFIG_MPU_STACK_GUARD
¶
Thread Stack Guards
Thread Stack Guards
Type: bool
Help¶
Enable thread stack guards via MPU. ARC supports built-in stack protection.
If your core supports that, it is preferred over MPU stack guard.
For ARC_MPU_VER == 2, it requires 2048 extra bytes and a strong start address
alignment, this will bring big waste of memory, so no support for it.

Direct dependencies¶
(ARC_CORE_MPU
&& ARC_MPU_VER
!= 2 && CPU_HAS_MPU
&& ARC
) || (ARM_MPU
&& CPU_HAS_MPU
&& ARM
)
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n
