RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 TdxDxe driver is dispatched early in DXE, due to being list in APRIORI. This module is responsible for below features: - Sets max logical cpus based on TDINFO - Sets PCI PCDs based on resource hobs - Set shared bit in MMIO region - Relocate Td mailbox and set its address in MADT table. 1. Set shared bit in MMIO region Qemu allows a ROM device to set to ROMD mode (default) or MMIO mode. When it is in ROMD mode, the device is mapped to guest memory and satisfies read access directly. In EDK2 Option ROM is treated as MMIO region. So Tdx guest access Option ROM via TDVMCALL(MMIO). But as explained above, since Qemu set the Option ROM to ROMD mode, the call of TDVMCALL(MMIO) always return INVALID_OPERAND. Tdvf then falls back to direct access. This requires to set the shared bit to corresponding PageTable entry. Otherwise it triggers GP fault. TdxDxe's entry point is the right place to set the shared bit in MMIO region because Option ROM has not been discoverd yet. 2. Relocate Td mailbox and set the new address in MADT Mutiprocessor Wakeup Table. 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]. TdxDxe registers for protocol notification (gQemuAcpiTableNotifyProtocolGuid) to call the AlterAcpiTable(), in which MADT table is altered by the above Mailbox address. The protocol will be installed in AcpiPlatformDxe when the MADT table provided by Qemu is ready. This is to maintain the simplicity of the AcpiPlatformDxe. AlterAcpiTable is the registered function which traverses the ACPI table list to find the original MADT from Qemu. After the new MADT is configured and installed, the original one will be uninstalled.

Create a change description in the format specified below to use in the source control commit log. #. Your commit message must include your ``Signed-off-by`` signature #. Submit your code to the TianoCore project using the process that the project documents on its web page. If the process is not documented, then submit the code on development email list for the project. #. It is preferred that contributions are submitted using the same copyright license as the base project. When that is not possible, then contributions using the following licenses can be accepted: - BSD (2-clause): http://opensource.org/licenses/BSD-2-Clause - BSD (3-clause): http://opensource.org/licenses/BSD-3-Clause - MIT: http://opensource.org/licenses/MIT - Python-2.0: http://opensource.org/licenses/Python-2.0 - Zlib: http://opensource.org/licenses/Zlib For documentation: - FreeBSD Documentation License https://www.freebsd.org/copyright/freebsd-doc-license.html Contributions of code put into the public domain can also be accepted. Contributions using other licenses might be accepted, but further review will be required. Developer Certificate of Origin ------------------------------- Your change description should use the standard format for a commit message, and must include your ``Signed-off-by`` signature. In order to keep track of who did what, all patches contributed must include a statement that to the best of the contributor's knowledge they have the right to contribute it under the specified license. The test for this is as specified in the `Developer's Certificate of Origin (DCO) 1.1 <https://developercertificate.org/>`__. The contributor certifies compliance by adding a line saying Signed-off-by: Developer Name developer@example.org where ``Developer Name`` is the contributor's real name, and the email address is one the developer is reachable through at the time of contributing. :: Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. Sample Change Description / Commit Message ------------------------------------------ :: From: Contributor Name <contributor@example.com> Subject: [Repository/Branch PATCH] Pkg-Module: Brief-single-line-summary Full-commit-message Signed-off-by: Contributor Name <contributor@example.com> Notes for sample patch email ```````````````````````````` - The first line of commit message is taken from the email's subject line following ``[Repository/Branch PATCH]``. The remaining portion of the commit message is the email's content. - ``git format-patch`` is one way to create this format Definitions for sample patch email `````````````````````````````````` - ``Repository`` is the identifier of the repository the patch applies. This identifier should only be provided for repositories other than ``edk2``. For example ``edk2-BuildSpecification`` or ``staging``. - ``Branch`` is the identifier of the branch the patch applies. This identifier should only be provided for branches other than ``edk2/master``. For example ``edk2/UDK2015``, ``edk2-BuildSpecification/release/1.27``, or ``staging/edk2-test``. - ``Module`` is a short identifier for the affected code or documentation. For example ``MdePkg``, ``MdeModulePkg/UsbBusDxe``, ``Introduction``, or ``EDK II INF File Format``. - ``Brief-single-line-summary`` is a short summary of the change. - The entire first line should be less than ~70 characters. - ``Full-commit-message`` a verbose multiple line comment describing the change. Each line should be less than ~70 characters. - ``Signed-off-by`` is the contributor's signature identifying them by their real/legal name and their email address. Submodules ---------- Submodule in EDK II is allowed but submodule chain should be avoided as possible as we can. Currently EDK II contains the following submodules - CryptoPkg/Library/OpensslLib/openssl - ArmPkg/Library/ArmSoftFloatLib/berkeley-softfloat-3 - MdeModulePkg/Universal/RegularExpressionDxe/oniguruma - MdeModulePkg/Library/BrotliCustomDecompressLib/brotli - BaseTools/Source/C/BrotliCompress/brotli ArmSoftFloatLib is actually required by OpensslLib. It's inevitable in openssl-1.1.1 (since stable201905) for floating point parameter conversion, but should be dropped once there's no such need in future release of openssl. To get a full, buildable EDK II repository, use following steps of git command .. code-block:: bash git clone https://github.com/tianocore/edk2.git cd edk2 git submodule update --init cd .. If there's update for submodules, use following git commands to get the latest submodules code. .. code-block:: bash cd edk2 git pull git submodule update Note: When cloning submodule repos, '--recursive' option is not recommended. EDK II itself will not use any code/feature from submodules in above submodules. So using '--recursive' adds a dependency on being able to reach servers we do not actually want any code from, as well as needlessly downloading code we will not use. .. =================================================================== ..
