4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync// Pointer to the DPC Protocol
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This constructor function caches the EFI_DPC_PROTOCOL pointer.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] ImageHandle The firmware allocated handle for the EFI image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] SystemTable A pointer to the EFI System Table.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The constructor always return EFI_SUCCESS.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // Locate the EFI_DPC_PROTOCOL in the handle database
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Status = gBS->LocateProtocol (&gEfiDpcProtocolGuid, NULL, (VOID **)&mDpc);
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Add a Deferred Procedure Call to the end of the DPC queue.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] DpcTpl The EFI_TPL that the DPC should be invoked.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] DpcProcedure Pointer to the DPC's function.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] DpcContext Pointer to the DPC's context. Passed to DpcProcedure
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync when DpcProcedure is invoked.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The DPC was queued.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_INVALID_PARAMETER DpcTpl is not a valid EFI_TPL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_INVALID_PARAMETER DpcProcedure is NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_OUT_OF_RESOURCES There are not enough resources available to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync add the DPC to the queue.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Dispatch the queue of DPCs. ALL DPCs that have been queued with a DpcTpl
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync value greater than or equal to the current TPL are invoked in the order that
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync they were queued. DPCs with higher DpcTpl values are invoked before DPCs with
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync lower DpcTpl values.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS One or more DPCs were invoked.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_NOT_FOUND No DPCs were invoked.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // Call the EFI_DPC_PROTOCOL to dispatch previously queued DPCs
