This patch set is based on Universal Payload on
https://universalpayload.github.io/documentation/payload-interfaces/index.html
This patch set introduce one general header, three different hob types
and how Universal Payload consume these hobs.
Zhiguang Liu (9):
MdePkg: Add Universal Payload general defination header file
MdePkg: Add new structure for the PCI Root Bridge Info Hob
UefiPayloadPkg: UefiPayload retrieve PCI root bridge from Guid Hob
MdePkg: Add new structure for the Universal Payload SMBios Table Info
Hob
MdeModulePkg/Universal/SmbiosDxe: Scan for existing tables
UefiPayloadPkg: Creat gPldSmbiosTableGuid Hob
MdePkg: Add new structure for the Universal Payload ACPI Table Info
Hob
MdeModulePkg/ACPI: Install ACPI table from HOB.
UefiPayloadPkg: Creat gPldAcpiTableGuid Hob

V1:
The default EfiSmbiosProtocol operates on an empty SMBIOS table.
The SMBIOS tables are provided by the bootloader on UefiPayloadPkg.
Scan for existing tables in SmbiosDxe and load them if they seem valid.
This fixes the settings menu not showing any hardware information, instead
only "0 MB RAM" was displayed.
Tests showed that the OS can still see the SMBIOS tables.
V2:
SmbiosDxe will get the SMBIOS from a guid Hob.
Aslo will keep the SmbiosHandle if it is available.

If HOB contains APCI table information, entry point of AcpiTableDxe.inf
should parse the APCI table from HOB, and install these tables.
We assume the whole ACPI table (starting with EFI_ACPI_2_0_ROOT_SYSTEM_DESCRIPTION_POINTER)
is contained by a single gEfiAcpiTableGuid HOB.

Adding Ray.
Hello Ray, I saw most of your comments in previous patch:
"[PATCH - resend] MdeModulePkg/Universal/SmbiosDxe: Scan for existing tables"
have been addressed in this patch series.
Could you help to check if there are additional comments for this patch? Thanks.

Should a check for the 'IntermediateAnchorString' be added here as well?

I might be wrong on this.
My take with the SMBIOS spec is that a 2.0 table is allowed to has this field greater than 2.
As long as a specific version of the SMBIOS spec still support this format (which is still true for version 3.0).
So I think I check like:
if (EntryPointStructure->MajorVersion < 2) {...}
should be used here.

I think RetrieveSmbiosFromHob() is an internal function.
Please help to remove the 'EFIAPI' keyword here.

Is it possible to abstract the codes that:
a) Search & parse of gPldSmbios3TableGuid
b) Search & parse of gPldSmbiosTableGuid
into a function?
I found that most of the logic is identical.

Sorry for missing one comment.
I think we can add below information for GUID information in SmbiosDxe.inf:
gPldSmbios3TableGuid ## CONSUMES ## HOB
gPldSmbiosTableGuid ## SOMETIMES_CONSUMES ## HOB

!= sizeof (SMBIOS_TABLE_ENTRY_POINT)) {

Note that AcpiTableDxe.inf is currently not part of the FV on
UefipayloadPkg, so there won't be any tables installed after all.

Is there any special consideration for removing the above check when the table is not from HOB?
Also, will the tables from HOB violate the rule mentioned in the below comment?
// Allocate memory for the FACS. This structure must be aligned

Do we need a check on the validity of 'Rsdt->Length'?
If 'Dsdt->Length - sizeof (EFI_ACPI_DESCRIPTION_HEADER)' underflows,
I think it is possible to consume invalid content.

Sorry for a question, is the condition in the above ASSERT a case that will never happen or
the above ASSERT is used for table content check?
If it is a check, please help to add error handling logic.

For a single ChildTable, if the installation fails here, is it still needed to install the FACS and DSDT within the ChildTable?

If there are errors occurred during the parse of the tables, do we still need to publish them anyway?

Zhiguang:
MdePkg definitions are from Industry Standards.
Universalpayload definitions are from its documentation 0.75 version. I don't think it belongs to the formal industry standards. Can you provide more information to show Universalpayload is the public industry standard?

In this patch, it removed gBS->InstallConfigurationTable(), it should also add AcpiTableDxe.inf to avoid regression.
Thanks,
