Abstract:
Definition in file Dpc.c.
| EFI_STATUS EFIAPI DpcDispatchDpc | ( | IN EFI_DPC_PROTOCOL * | This | ) |
Dispatch the queue of DPCs. ALL DPCs that have been queued with a DpcTpl value greater than or equal to the current TPL are invoked in the order that they were queued. DPCs with higher DpcTpl values are invoked before DPCs with lower DpcTpl values.
| This | Protocol instance pointer. |
| EFI_SUCCESS | One or more DPCs were invoked. |
| EFI_NOT_FOUND | No DPCs were invoked. |
| EFI_STATUS EFIAPI DpcDriverEntryPoint | ( | IN EFI_HANDLE | ImageHandle, |
| IN EFI_SYSTEM_TABLE * | SystemTable | ||
| ) |
The entry point for DPC driver which installs the EFI_DPC_PROTOCOL onto a new handle.
| ImageHandle | The image handle of the driver. |
| SystemTable | The system table. |
| EFI_SUCCESS | The DPC queues were initialized and the EFI_DPC_PROTOCOL was installed onto a new handle. |
| Others | Failed to install EFI_DPC_PROTOCOL. |
| EFI_STATUS EFIAPI DpcQueueDpc | ( | IN EFI_DPC_PROTOCOL * | This, |
| IN EFI_TPL | DpcTpl, | ||
| IN EFI_DPC_PROCEDURE | DpcProcedure, | ||
| IN VOID *DpcContext | OPTIONAL | ||
| ) |
Add a Deferred Procedure Call to the end of the DPC queue.
| This | Protocol instance pointer. |
| DpcTpl | The EFI_TPL that the DPC should be invoked. |
| DpcProcedure | Pointer to the DPC's function. |
| DpcContext | 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. |
