functionIOTimeStampStartConstant

static inline void IOTimeStampStartConstant(

	uintptr_t b = 0,
	uintptr_t c = 0,
	uintptr_t d = 0

Emits a kdebug interval-start tracepoint: KERNEL_DEBUG_CONSTANT with debug code csc | DBG_FUNC_START and arguments a, b, c, d. csc is a class/subclass/code constant, typically built with the IODBG_* macros over the DBG_IOKIT class. Compiled into all kernel configurations; a no-op at run time unless kernel tracing is enabled.

functionIOTimeStampEndConstant

static inline void IOTimeStampEndConstant(
	uintptr_t csc,
	uintptr_t a = 0,
	uintptr_t b = 0,
	uintptr_t c = 0,
	uintptr_t d = 0
)

Emits a kdebug interval-end tracepoint: KERNEL_DEBUG_CONSTANT with debug code csc | DBG_FUNC_END and arguments a, b, c, d; pairs with IOTimeStampStartConstant. Compiled into all kernel configurations; a no-op unless kernel tracing is enabled.

functionIOTimeStampConstant

static inline void IOTimeStampConstant(
	uintptr_t csc,
	uintptr_t a = 0,
	uintptr_t b = 0,
	uintptr_t c = 0,

Emits a standalone kdebug tracepoint: KERNEL_DEBUG_CONSTANT with debug code csc | DBG_FUNC_NONE and arguments a, b, c, d. Compiled into all kernel configurations; a no-op unless kernel tracing is enabled.

functionIOTimeStampConstantFiltered

static inline void IOTimeStampConstantFiltered(
	uintptr_t csc,
	uintptr_t a = 0,
	uintptr_t b = 0,
	uintptr_t c = 0,
	uintptr_t d = 0
)

Emits a standalone kdebug tracepoint through KERNEL_DEBUG_CONSTANT_FILTERED, so the event is suppressed when tracing runs in filtered (reduced) mode. Debug code is csc | DBG_FUNC_NONE with arguments a, b, c, d.
