OvmfPkg: Create initial version of PlatformInitLib BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863 There are 3 variants of PlatformPei in OvmfPkg: - OvmfPkg/PlatformPei - OvmfPkg/XenPlatformPei - OvmfPkg/Bhyve/PlatformPei/PlatformPei.inf These PlatformPeis can share many common codes, such as Cmos / Hob / Memory / Platform related functions. This commit (and its following several patches) are to create a PlatformInitLib which wraps the common code called in above PlatformPeis. In this initial version of PlatformInitLib, below Cmos related functions are introduced: - PlatformCmosRead8 - PlatformCmosWrite8 - PlatformDebugDumpCmos They correspond to the functions in OvmfPkg/PlatformPei: - CmosRead8 - CmosWrite8 - DebugDumpCmos Considering this PlatformInitLib will be used in SEC phase, global variables and dynamic PCDs are avoided. We use PlatformInfoHob to exchange information between functions. EFI_HOB_PLATFORM_INFO is the data struct which contains the platform information, such as HostBridgeDevId, BootMode, S3Supported, SmmSmramRequire, etc. After PlatformInitLib is created, OvmfPkg/PlatformPei is refactored with this library.

OvmfPkg: Update PlatformInitLib to process Tdx hoblist RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 When host VMM create the Td guest, the system memory informations are stored in TdHob, which is a memory region described in Tdx metadata. The system memory region in TdHob should be accepted before it can be accessed. So the newly added function (ProcessTdxHobList) is to process the TdHobList to accept the memory. Because TdHobList is provided by host VMM which is not trusted, so its content should be checked before it is consumed by TDVF. Because ProcessTdxHobList is to be called in SEC phase, so PlatformInitLib.inf is updated to support SEC. Note: In this patch it is BSP which accepts the pages. So there maybe boot performance issue. There are some mitigations to this issue, such as lazy accept, 2M accept page size, etc. We will re-visit here in the future. EFI_RESOURCE_MEMORY_UNACCEPTED is a new ResourceType in EFI_HOB_RESOURCE_DESCRIPTOR. It is defined for the unaccepted memory passed from Host VMM. This is proposed in microsoft/mu_basecore#66 files#diff-b20a11152d1ce9249c691be5690b4baf52069efadf2e2546cdd2eb663d80c9 e4R237 according to UEFI-Code-First. The proposal was approved in 2021 in UEFI Mantis, and will be added to the new PI.next specification. Per the MdePkg reviewer's comments, before this new ResourceType is added in the PI spec, it should not be in MdePkg. So it is now defined as an internal implementation and will be moved to MdePkg/Include/Pi/PiHob.h after it is added in PI spec. See https://edk2.groups.io/g/devel/message/87641 PcdTdxAcceptPageSize is added for page accepting. Currently TDX supports 4K and 2M accept page size. The default value is 2M. Tdx guest is only supported in X64. So for IA32 ProcessTdxHobList just returns EFI_UNSUPPORTED.

Ovmf/PlatformPei: Use host-provided GPA end if available Read the "hardware-info" item from fw-cfg to extract specifications of PCI host bridges and analyze the 64-bit apertures of them to find out the highest 64-bit MMIO address required which determines the address space required by the guest, and, consequently, the FirstNonAddress used to calculate size of physical addresses. Using the static PeiHardwareInfoLib, read the fw-cfg file of hardware information to extract, one by one, all the host bridges. Find the last 64-bit MMIO address of each host bridge, using the HardwareInfoPciHostBridgeLib API, and compare it to an accumulate value to discover the highest address used, which corresponds to the highest value that must be included in the guest's physical address space. Given that platforms with multiple host bridges may provide the PCI apertures' addresses, the memory detection logic must take into account that, if the host provided the MMIO windows that can and must be used, the guest needs to take those values. Therefore, if the MMIO windows are found in the host-provided fw-cfg file, skip all the logic calculating the physical address size and just use the value provided. Since each PCI host bridge corresponds to an element in the information provided by the host, each of these must be analyzed looking for the highest address used.
