RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 In TDX the guest firmware is designed to publish a multiprocessor-wakeup structure to let the guest-bootstrap processor wake up guest-application processors with a mailbox. The mailbox is memory that the guest firmware can reserve so each guest virtual processor can have the guest OS send a message to them. The address of the mailbox is recorded in the MADT table. See [ACPI]. To maintain the simplicity of the AcpiPlatformDxe, the MADT ACPI table will be altered in another driver (TdxDxe) by installing a protocol to notify that the ACPI table provided by Qemu is ready. Then in TdxDxe a notification functioin will be called to alter the MADT table to recorded the mailbox address. The protocol is gQemuAcpiTableNotifyProtocolGuid.
