|
|
|
||
|
|
This function is used to store a boot script record into a given boot
|
||
|
|
script table. If the table specified by TableName is nonexistent in the
|
||
|
|
system, a new table will automatically be created and then the script record
|
||
|
|
will be added into the new table. A boot script table can add new script records
|
||
|
|
until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only
|
||
|
|
meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is
|
||
|
|
responsible for allocating necessary memory for the script.
|
||
|
|
|
||
|
|
This function has a variable parameter list. The exact parameter list depends on
|
||
|
|
the OpCode that is passed into the function. If an unsupported OpCode or illegal
|
||
|
|
parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
|
||
|
|
If there are not enough resources available for storing more scripts, this function returns
|
||
|
|
EFI_OUT_OF_RESOURCES.
|
||
|
|
|
||
|
|
@param This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.
|
||
|
|
@param TableName Name of the script table. Currently, the only meaningful value is
|
||
|
|
EFI_ACPI_S3_RESUME_SCRIPT_TABLE.
|
||
|
|
@param OpCode The operation code (opcode) number.
|
||
|
|
@param ... Argument list that is specific to each opcode.
|
||
|
|
|
||
|
|
@retval EFI_SUCCESS The operation succeeded. A record was added into the
|
||
|
|
specified script table.
|
||
|
|
@retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported.
|
||
|
|
If the opcode is unknow or not supported because of the PCD
|
||
|
|
Feature Flags.
|
||
|
|
@retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script.

Closes the specified script table.

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