#define	TICK_UNLOCK(state)   LOS_SpinUnlockRestore(&g_tickSpin, (state))
#define	CYCLE_TO_NS(cycles)   ((cycles) * g_cycle2NsScale)
#define	TIMER_MAXLOAD   0xffffffff

函数
VOID	OsTickHandler (VOID)
UINT32	OsTickInit (VOID)
VOID	OsTickStart (VOID)

变量
SPIN_LOCK_S	g_tickSpin
volatile UINT64	g_tickCount [LOSCFG_KERNEL_CORE_NUM]
DOUBLE	g_cycle2NsScale

宏定义说明

CYCLE_TO_NS

#define CYCLE_TO_NS

(

cycles

)

((cycles) * g_cycle2NsScale)

TICK_LOCK

#define TICK_LOCK

(

state

)

LOS_SpinLockSave(&g_tickSpin, &(state))

TICK_UNLOCK

#define TICK_UNLOCK

(

state

)

LOS_SpinUnlockRestore(&g_tickSpin, (state))

TIMER_MAXLOAD

#define TIMER_MAXLOAD   0xffffffff

Current system timer register is 32 bit, therefore TIMER_MAXLOAD define just in order to avoid ambiguity.
