27 | The InstallAcpiTable() function allows a caller to install an \r | |
28 | ACPI table. When successful, the table will be linked by the \r | |
29 | RSDT/XSDT. AcpiTableBuffer specifies the table to be installed. \r | |
30 | InstallAcpiTable() will make a copy of the table and insert the \r | |
31 | copy into the RSDT/XSDT. InstallAcpiTable() must insert the new \r | |
32 | table at the end of the RSDT/XSDT. To prevent namespace \r | |
33 | collision, ACPI tables may be created using UEFI ACPI table \r | |
34 | format. See Appendix O. On successful output, TableKey is \r | |
35 | initialized with a unique key. Its value may be used in a \r | |
36 | subsequent call to UninstallAcpiTable to remove an ACPI table. \r | |
37 | If an EFI application is running at the time of this call, the \r | |
38 | relevant EFI_CONFIGURATION_TABLE pointer to the RSDT is no \r | |
39 | longer considered valid. \r | |
