Add the SMBIOS Table generator code to the DynamicTablesPkg. This change includes adding new logic to the DynamicTableManager to process and add SMBIOS tables and augmenting the existing SMBIOS Factory generator to include installing multiple SMBIOS tables.

/** Entrypoint of Dynamic Table Manager Dxe.
|
|
|
|
The Dynamic Table Manager uses the Configuration Manager Protocol
|
|
to get the list of ACPI and SMBIOS tables to install. For each table
|
|
in the list it requests the corresponding ACPI/SMBIOS table factory for
|
|
a generator capable of building the ACPI/SMBIOS table.
|
|
If a suitable table generator is found, it invokes the generator interface
|
|
to build the table. The Dynamic Table Manager then installs the
|
|
table and invokes another generator interface to free any resources
|
|
allocated for building the table.
|
|
|
|
Since platforms may support generation of either ACPI or SMBIOS or both
|
|
tables, register for notification of the corresponding protocols being
|
|
ready and dispatch their table builds accordingly.
|
|
|
|
@param ImageHandle Handle to the image.
|
|
@param SystemTable Pointer to the system table.
|
|
|
|
@retval EFI_SUCCESS Success.
|
|
@retval EFI_OUT_OF_RESOURCES Memory allocation failed.
