The InstallAcpiTable() function allows a caller to install an ACPI table. When successful, the table will be linked by the RSDT/XSDT. AcpiTableBuffer specifies the table to be installed. InstallAcpiTable() will make a copy of the table and insert the copy into the RSDT/XSDT. InstallAcpiTable() must insert the new table at the end of the RSDT/XSDT. To prevent namespace collision, ACPI tables may be created using UEFI ACPI table format. If this protocol is used to install a table with a signature already present in the system, the new table will not replace the existing table. It is a platform implementation decision to add a new table with a signature matching an existing table or disallow duplicate table signatures and return EFI_ACCESS_DENIED. On successful output, TableKey is initialized with a unique key. Its value may be used in a subsequent call to UninstallAcpiTable to remove an ACPI table. If an EFI application is running at the time of this call, the relevant EFI_CONFIGURATION_TABLE pointer to the RSDT is no longer considered valid.
This | A pointer to a EFI_ACPI_TABLE_PROTOCOL. | |
AcpiTableBuffer | A pointer to a buffer containing the ACPI table to be installed. | |
AcpiTableBufferSize | Specifies the size, in bytes, of the AcpiTableBuffer buffer. | |
TableKey | Returns a key to refer to the ACPI table. |
EFI_SUCCESS | The table was successfully inserted | |
EFI_INVALID_PARAMETER | Either AcpiTableBuffer is NULL, TableKey is NULL, or AcpiTableBufferSize and the size field embedded in the ACPI table pointed to by AcpiTableBuffer are not in sync. | |
EFI_OUT_OF_RESOURCES | Insufficient resources exist to complete the request. | |
EFI_ACCESS_DENIED | The table signature matches a table already present in the system and platform policy does not allow duplicate tables of this type. |

The UninstallAcpiTable() function allows a caller to remove an ACPI table. The routine will remove its reference from the RSDT/XSDT. A table is referenced by the TableKey parameter returned from a prior call to InstallAcpiTable(). If an EFI application is running at the time of this call, the relevant EFI_CONFIGURATION_TABLE pointer to the RSDT is no longer considered valid.
This | A pointer to a EFI_ACPI_TABLE_PROTOCOL. | |
TableKey | Specifies the table to uninstall. The key was returned from InstallAcpiTable(). |
EFI_SUCCESS | The table was successfully inserted | |
EFI_NOT_FOUND | TableKey does not refer to a valid key for a table entry. | |
EFI_OUT_OF_RESOURCES | Insufficient resources exist to complete the request. |
