	Architecture-specific function to walk the stack.

Detailed Description

Architecture-specific Stack Walk APIs.

To add API support to an architecture, arch_stack_walk() should be implemented and a non-user configurable Kconfig ARCH_HAS_STACKWALK that is default to y should be created in the architecture's top level Kconfig, with all the relevant dependencies.

stack_trace_callback_fn - Callback for arch_stack_walk

Parameters

cookie	Caller supplied pointer handed back by arch_stack_walk
addr	The stack entry address to consume

Returns

True, if the entry was consumed or skipped. False, if there is no space left to store

Function Documentation
