37 | Adds a record into a specified Framework boot script table.\r | |
38 | \r | |
39 | This function is used to store a boot script record into a given boot\r | |
40 | script table. If the table specified by TableName is nonexistent in the\r | |
41 | system, a new table will automatically be created and then the script record\r | |
42 | will be added into the new table. A boot script table can add new script records\r | |
43 | until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only\r | |
44 | meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is\r | |
45 | responsible for allocating necessary memory for the script.\r | |
46 | \r | |
47 | This function has a variable parameter list. The exact parameter list depends on\r | |
48 | the OpCode that is passed into the function. If an unsupported OpCode or illegal\r | |
49 | parameter list is passed in, this function returns EFI_INVALID_PARAMETER.\r | |
50 | If there are not enough resources available for storing more scripts, this function returns\r | |
51 | EFI_OUT_OF_RESOURCES.\r | |
52 | \r | |
53 | @param[in] This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.\r | |
54 | @param[in] TableName Name of the script table. Currently, the only meaningful value is\r | |
55 | EFI_ACPI_S3_RESUME_SCRIPT_TABLE.\r | |
56 | @param[in] OpCode The operation code (opcode) number.\r | |
57 | @param[in] ... Argument list that is specific to each opcode.\r | |
58 | \r | |
59 | @retval EFI_SUCCESS The operation succeeded. A record was added into the\r | |
60 | specified script table.\r | |
61 | @retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported.\r | |
62 | If the opcode is unknow or not supported because of the PCD\r | |
63 | Feature Flags.\r | |
64 | @retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script.\r | |

77 | Closes the specified script table.\r | |
78 | \r | |
79 | This function closes the specified boot script table and returns the base address\r | |
80 | of the table. It allocates a new pool to duplicate all the boot scripts in the specified\r | |
81 | table. Once this function is called, the specified table will be destroyed after it is\r | |
82 | copied into the allocated pool. As a result, any attempts to add a script record into a\r | |
83 | closed table will cause a new table to be created. The base address of the allocated pool\r | |
84 | will be returned in Address. After using the boot script table, the caller is responsible\r | |
85 | for freeing the pool that is allocated by this function. If the boot script table,\r | |
86 | such as EFI_ACPI_S3_RESUME_SCRIPT_TABLE, is required to be stored in a nonperturbed\r | |
87 | memory region, the caller should copy the table into the nonperturbed memory region by itself.\r | |

92 | @param[in] Address A pointer to the physical address where the table begins.\r | |
93 | \r | |
94 | @retval EFI_SUCCESS The table was successfully returned.\r | |
95 | @retval EFI_NOT_FOUND The specified table was not created previously.\r | |
96 | @retval EFI_OUT_OF_RESOURCE Memory is insufficient to hold the reorganized boot script table.\r | |
