Help¶

Select this option to enable hardware-based platform features to catch stack overflows when the system is running in privileged mode. If CONFIG_USERSPACE is not enabled, the system is always running in privileged mode.

Note that this does not necessarily prevent corruption and assertions about the overall system state when a fault is triggered cannot be made.

Direct dependencies¶
