Value:
{ \ 0x480f8ae9, 0xc46, 0x4aa9, { 0xbc, 0x89, 0xdb, 0x9f, 0xba, 0x61, 0x98, 0x6 } \ }
typedef EFI_STATUS(EFIAPI * EFI_DPC_DISPATCH_DPC)(IN EFI_DPC_PROTOCOL *This) |
Dispatch the queue of DPCs.
DPCs with DpcTpl value greater than the current TPL value are queued, and then DPCs with DpcTpl value lower than the current TPL value are queued. All DPCs in the first group (higher DpcTpl values) are invoked before DPCs in the second group (lower DpcTpl values).
This | Protocol instance pointer. |
EFI_SUCCESS | One or more DPCs were invoked. | |
EFI_NOT_FOUND | No DPCs were invoked. |
typedef VOID(EFIAPI * EFI_DPC_PROCEDURE)(IN VOID *DpcContext) |
Invoke a Deferred Procedure Call.
DpcContext | The pointer to the Deferred Procedure Call's context, which is implementation dependent. |
typedef struct _EFI_DPC_PROTOCOL EFI_DPC_PROTOCOL |
typedef EFI_STATUS(EFIAPI * EFI_DPC_QUEUE_DPC)(IN EFI_DPC_PROTOCOL *This, IN EFI_TPL DpcTpl, IN EFI_DPC_PROCEDURE DpcProcedure, IN VOID *DpcContext) |
Add a Deferred Procedure Call to the end of the DPC queue.
This | The protocol instance pointer. | |
DpcTpl | The EFI_TPL that the DPC should invoke. | |
DpcProcedure | The pointer to the DPC's function. | |
DpcContext | The pointer to the DPC's context. Passed to DpcProcedure when DpcProcedure is invoked. |
EFI_SUCCESS | The DPC was queued. | |
EFI_INVALID_PARAMETER | DpcTpl is not a valid EFI_TPL. | |
EFI_INVALID_PARAMETER | DpcProcedure is NULL. | |
EFI_OUT_OF_RESOURCES | There are not enough resources available to add the DPC to the queue. |
EFI_GUID gEfiDpcProtocolGuid |
DPC Protocol GUID variable.
