Subject: [PATCH V7 30/37] OvmfPkg: Update AcpiPlatformDxe to alter MADT table
Date: Mon, 28 Feb 2022 15:21:02 +0800 [thread overview]
Message-ID: <45000693508b7ec0c0a8f0261ce47e51bf022763.1646031165.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1646031164.git.min.m.xu@intel.com>
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.
