SYS_PORT_TRACING_FUNC

#define SYS_PORT_TRACING_FUNC	(		type,
			func,
			...
	)		_SYS_PORT_TRACE_IF_NOT_DISABLED(type, _SYS_PORT_TRACING_FUNC(type, func), __VA_ARGS__)

#include <include/zephyr/tracing/tracing_macros.h>

Tracing macro for function calls which are not directly associated with a specific type of object.

Parameters

type	Type of tracing event or object type
func	Name of the function responsible for the call. This does not need to exactly match the name of the function but should rather match what the user called in case of system calls etc. That is, we can often omit the z_vrfy/z_impl part of the name.
...	Additional parameters relevant to the tracing call

SYS_PORT_TRACING_FUNC_BLOCKING

#define SYS_PORT_TRACING_FUNC_BLOCKING	(		type,
			func,

Tracing macro for when a function blocks during its execution.

Parameters

type	Type of tracing event or object type
func	Name of the function responsible for the call. This does not need to exactly match the name of the function but should rather match what the user called in case of system calls etc. That is, we can often omit the z_vrfy/z_impl part of the name.
