Detailed Description

Internal kernel APIs implemented at the architecture layer.

Not all architecture-specific defines are here, APIs that are used by public functions and macros are defined in include/zephyr/arch/arch_interface.h.

For all inline functions prototyped here, the implementation is expected to be provided by arch/ARCH/include/kernel_arch_func.h
