Adds, updates, or removes a configuration table entry from the System Management System Table.

|
The SmmInstallConfigurationTable() function is used to maintain the list
|
|
of configuration tables that are stored in the System Management System
|
|
Table. The list is stored as an array of (GUID, Pointer) pairs. The list
|
|
must be allocated from pool memory with PoolType set to EfiRuntimeServicesData.
|
|
|
|
@param[in] SystemTable A pointer to the SMM System Table (SMST).
|
|
@param[in] Guid A pointer to the GUID for the entry to add, update, or remove.
|
|
@param[in] Table A pointer to the buffer of the table to add.
|
|
@param[in] TableSize The size of the table to install.
|
|
|
|
@retval EFI_SUCCESS The (Guid, Table) pair was added, updated, or removed.
|
|
@retval EFI_INVALID_PARAMETER Guid is not valid.
|
|
@retval EFI_NOT_FOUND An attempt was made to delete a non-existent entry.
|
|
@retval EFI_OUT_OF_RESOURCES There is not enough memory available to complete the operation.
