函数说明

OsGetHwiForm()

STATIC INLINE HwiHandleInfo * OsGetHwiForm

(

UINT32

STATIC INLINE VOID OsHwiControllerReg

(

const HwiControllerOps *

When interrupting the controller driver initialization, controller-related operations need to be implemented and registered;Because the function pointer is not judged in the abstraction layer, all function members defined in HwiControllerOps need to be registered. If this function is not supported, you can call the LOS_Panic interface in the implementation of the stub function to report an error in time.

OsHwiInit()

UINT32 OsHwiInit ( VOID  )

extern

OsIntEntry()

VOID OsIntEntry ( VOID  )

extern

OS Interrupt entry, called by assembly code in dispatch.S. The unified entrance of external interrupt is taken over by the kernel. The handleIrq hook function MUST be registered in the interrupt controller driver layer, otherwise it will not respond. eg: Used for arm(cortex-a/r)/arm64.

OsIntGetPara()

STATIC INLINE HWI_ARG_T OsIntGetPara

(

UINT32

num

)

OsIntHandle()

VOID OsIntHandle ( UINT32  hwiNum, HwiHandleInfo *  handleForm  )

extern

If the interrupt is in the scenario where the kernel does not take over, the interrupt controller driver layer realizes the general entry ISR and passes the hwiNum and handleForm to this interface. eg: Used for arm(cortex-m),xtensa,riscv.

OsIntIsRegisted()

STATIC INLINE BOOL OsIntIsRegisted

(

UINT32

num

)

OsIntNumGet()

STATIC INLINE UINT32 OsIntNumGet

(

VOID

)

OsIntVersionGet()

STATIC INLINE CHAR * OsIntVersionGet

(

VOID

)

OsIrqNestingCntGet()

size_t OsIrqNestingCntGet ( VOID  )

extern

OsIrqNestingCntSet()

VOID OsIrqNestingCntSet ( size_t  val )
