Basic Data Types

This section defines some data types and values that are fundamental to interrupt management.



 
typedef KernelID        InterruptSetID;

typedef long            InterruptMemberNumber;



 
enum {

kReturnToParentWhenComplete = 0x00000001,

kReturnToParentWhenNotComplete = 0x00000002

};



 
typedef struct InterruptSetMember {

    InterruptSetID                  set;

    InterruptMemberNumber           member;

} InterruptSetMember;



 
enum{

    kISTChipInterruptSource      = 0,

    kISTOutputDMAInterruptSource = 1,

    kISTInputDMAInterruptSource  = 2,

    kISTPropertyMemberCount      = 3

};



 
typedef InterruptSetMember ISTProperty[ kISTPropertyMemberCount ];



 
#define kISTPropertyName "driver-ist"



 
typedef long InterruptReturnValue;

enum

{

    kFirstMemberNumber          =   1,

    kIsrIsComplete              =   0

    kIsrIsNotComplete           = -1,

    kMemberNumberParent         = -2,

};



 
typedef Boolean InterruptSourceState;

enum

{

    kSourceWasEnabled           = true,

    kSourceWasDisabled          = false

};
