This service must interact with 613 the Security Architectural Protocol to authenticate DXE drivers before they are executed. 614 This process is continued until no more DXE drivers can be executed. 615 616 @retval EFI_SUCCESS One or more DXE driver were dispatched. 617 @retval EFI_NOT_FOUND No DXE drivers were dispatched. 618 @retval EFI_ALREADY_STARTED An attempt is being made to start the DXE Dispatcher recursively. 619 Thus, no action was taken. 620 621**/ 622typedef 623EFI_STATUS 624(EFIAPI *EFI_DISPATCH)( 625 VOID 626 ); 627 628/** 629 Clears the Schedule on Request (SOR) flag for a component that is stored in a firmware volume. 630 631 @param FirmwareVolumeHandle The handle of the firmware volume that contains the file specified by FileName. 632 @param FileName A pointer to the name of the file in a firmware volume. 633 634 @retval EFI_SUCCESS The DXE driver was found and its SOR bit was cleared. 635 @retval EFI_NOT_FOUND The DXE driver does not exist, or the DXE driver exists and its SOR 636 bit is not set. 637 638**/ 639typedef 640EFI_STATUS 641(EFIAPI *EFI_SCHEDULE)( 642 IN EFI_HANDLE FirmwareVolumeHandle, 643 IN CONST EFI_GUID *FileName 644 ); 645 646/** 647 Promotes a file stored in a firmware volume from the untrusted to the trusted state. 648 649 @param FirmwareVolumeHandle The handle of the firmware volume that contains the file specified by FileName. 650 @param DriverName A pointer to the name of the file in a firmware volume. 651 652 @return Status of promoting FFS from untrusted to trusted 653 state. 654 @retval EFI_NOT_FOUND The file was not found in the untrusted state. 655 656**/ 657typedef 658EFI_STATUS 659(EFIAPI *EFI_TRUST)( 660 IN EFI_HANDLE FirmwareVolumeHandle, 661 IN CONST EFI_GUID *FileName 662 ); 663 664/** 665 Creates a firmware volume handle for a firmware volume that is present in system memory. 666 667 @param FirmwareVolumeHeader A pointer to the header of the firmware volume. 668 @param Size The size, in bytes, of the firmware volume. 669 @param FirmwareVolumeHandle On output, a pointer to the created handle. 670 671 @retval EFI_SUCCESS The EFI_FIRMWARE_VOLUME_PROTOCOL and 672 EFI_DEVICE_PATH_PROTOCOL were installed onto 673 FirmwareVolumeHandle for the firmware volume described 674 by FirmwareVolumeHeader and Size. 675 @retval EFI_VOLUME_CORRUPTED The firmware volume described by FirmwareVolumeHeader 676 and Size is corrupted. 677 @retval EFI_OUT_OF_RESOURCES There are not enough system resources available to produce the 678 EFI_FIRMWARE_VOLUME_PROTOCOL and EFI_DEVICE_PATH_PROTOCOL 679 for the firmware volume described by FirmwareVolumeHeader and Size. 680 681**/ 682typedef 683EFI_STATUS 684(EFIAPI *EFI_PROCESS_FIRMWARE_VOLUME)( 685 IN CONST VOID *FirmwareVolumeHeader, 686 IN UINTN Size, 687 OUT EFI_HANDLE *FirmwareVolumeHandle 688 ); 689 690// 691// DXE Services Table 692// 693#define DXE_SERVICES_SIGNATURE 0x565245535f455844ULL 694#define DXE_SPECIFICATION_MAJOR_REVISION 1 695#define DXE_SPECIFICATION_MINOR_REVISION 40 696#define DXE_SERVICES_REVISION ((DXE_SPECIFICATION_MAJOR_REVISION<<16) | (DXE_SPECIFICATION_MINOR_REVISION)) 697 698typedef struct { 699 /// 700 /// The table header for the DXE Services Table. 701 /// This header contains the DXE_SERVICES_SIGNATURE and DXE_SERVICES_REVISION values. 702 /// 703 EFI_TABLE_HEADER Hdr; 704 705 // 706 // Global Coherency Domain Services 707 // 708 EFI_ADD_MEMORY_SPACE AddMemorySpace; 709 EFI_ALLOCATE_MEMORY_SPACE AllocateMemorySpace; 710 EFI_FREE_MEMORY_SPACE FreeMemorySpace; 711 EFI_REMOVE_MEMORY_SPACE RemoveMemorySpace; 712 EFI_GET_MEMORY_SPACE_DESCRIPTOR GetMemorySpaceDescriptor; 713 EFI_SET_MEMORY_SPACE_ATTRIBUTES SetMemorySpaceAttributes; 714 EFI_GET_MEMORY_SPACE_MAP GetMemorySpaceMap; 715 EFI_ADD_IO_SPACE AddIoSpace; 716 EFI_ALLOCATE_IO_SPACE AllocateIoSpace; 717 EFI_FREE_IO_SPACE FreeIoSpace; 718 EFI_REMOVE_IO_SPACE RemoveIoSpace; 719 EFI_GET_IO_SPACE_DESCRIPTOR GetIoSpaceDescriptor; 720 EFI_GET_IO_SPACE_MAP GetIoSpaceMap; 721 722 // 723 // Dispatcher Services 724 // 725 EFI_DISPATCH Dispatch; 726 EFI_SCHEDULE Schedule; 727 EFI_TRUST Trust; 728 // 729 // Service to process a single firmware volume found in a capsule 730 // 731 EFI_PROCESS_FIRMWARE_VOLUME ProcessFirmwareVolume; 732 // 733 // Extensions to Global Coherency Domain Services 734 // 735 EFI_SET_MEMORY_SPACE_CAPABILITIES SetMemorySpaceCapabilities; 736} DXE_SERVICES; 737 738typedef DXE_SERVICES EFI_DXE_SERVICES; 739 740#endif 741
