CONFIG_MPU_STACK_GUARD¶

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.
