If the table specified by TableName is nonexistent in the 50 system, a new table will automatically be created and then the script record 51 will be added into the new table. A boot script table can add new script records 52 until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only 53 meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is 54 responsible for allocating necessary memory for the script. 55 56 This function has a variable parameter list. The exact parameter list depends on 57 the OpCode that is passed into the function. If an unsupported OpCode or illegal 58 parameter list is passed in, this function returns EFI_INVALID_PARAMETER. 59 If there are not enough resources available for storing more scripts, this function returns 60 EFI_OUT_OF_RESOURCES. 61 62 @param[in] This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance. 63 @param[in] TableName Name of the script table. Currently, the only meaningful value is 64 EFI_ACPI_S3_RESUME_SCRIPT_TABLE. 65 @param[in] OpCode The operation code (opcode) number. 66 @param[in] ... Argument list that is specific to each opcode. 67 68 @retval EFI_SUCCESS The operation succeeded. A record was added into the 69 specified script table. 70 @retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported. 71 If the opcode is unknow or not supported because of the PCD 72 Feature Flags. 73 @retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script. 74 75 **/ 76 EFI_STATUS 77 EFIAPI 78 BootScriptWrite ( 79 IN EFI_BOOT_SCRIPT_SAVE_PROTOCOL *This, 80 IN UINT16 TableName, 81 IN UINT16 OpCode, 82 ... 83 ); 84 85 /** 86 Closes the specified script table. 87 88 This function closes the specified boot script table and returns the base address 89 of the table. It allocates a new pool to duplicate all the boot scripts in the specified 90 table. Once this function is called, the specified table will be destroyed after it is 91 copied into the allocated pool. As a result, any attempts to add a script record into a 92 closed table will cause a new table to be created. The base address of the allocated pool 93 will be returned in Address. After using the boot script table, the caller is responsible 94 for freeing the pool that is allocated by this function. If the boot script table, 95 such as EFI_ACPI_S3_RESUME_SCRIPT_TABLE, is required to be stored in a nonperturbed 96 memory region, the caller should copy the table into the nonperturbed memory region by itself. 97 98 @param[in] This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance. 99 @param[in] TableName Name of the script table. Currently, the only meaningful value is 100 EFI_ACPI_S3_RESUME_SCRIPT_TABLE. 101 @param[in] Address A pointer to the physical address where the table begins. 102 103 @retval EFI_SUCCESS The table was successfully returned. 104 @retval EFI_NOT_FOUND The specified table was not created previously. 105 @retval EFI_OUT_OF_RESOURCE Memory is insufficient to hold the reorganized boot script table. 106 @retval EFI_UNSUPPORTED The table type is not EFI_ACPI_S3_RESUME_SCRIPT_TABLE. 107 108 **/ 109 EFI_STATUS 110 EFIAPI 111 BootScriptCloseTable ( 112 IN EFI_BOOT_SCRIPT_SAVE_PROTOCOL *This, 113 IN UINT16 TableName, 114 OUT EFI_PHYSICAL_ADDRESS *Address 115 ); 116 #endif //_INTERNAL_BOOT_SCRIPT_SAVE_H_ 117
