This was due to the way the OVMF code expects Cloud Hypervisor > to rely on PVH to retrieve information like memory below 4GiB as well as > the ACPI tables. > > This is why this series takes care of identifying when running on TDX in > order to handle things differently. For the memory below 4GiB, it falls > back onto the CMOS to retrieve the correct information, and for the ACPI > tables, it relies on the HOB to obtain every table individually before > to expose them to the guest OS. > > With these two use cases properly handled by this series, it is now > possible to use the IntelTdxX64 target to build an OVMF binary that > works both for QEMU and Cloud Hypervisor on a TDX platform. > > Sebastien Boeuf (3): > OvmfPkg/PlatformInitLib: Differentiate TDX case for Cloud Hypervisor > OvmfPkg/PlatformInitLib: Transfer GUID Extension HOB > OvmfPkg/AcpiPlatformDxe: Differentiate TDX case for Cloud Hypervisor > > ArmVirtPkg/ArmVirtQemu.dsc | 1 + > OvmfPkg/AcpiPlatformDxe/AcpiPlatform.c | 8 +- > OvmfPkg/AcpiPlatformDxe/AcpiPlatform.h | 6 ++ > OvmfPkg/AcpiPlatformDxe/AcpiPlatformDxe.inf | 3 + > OvmfPkg/AcpiPlatformDxe/CloudHvAcpi.c | 87 +++++++++++++++++++++ > OvmfPkg/Library/PlatformInitLib/IntelTdx.c | 5 ++ > OvmfPkg/Library/PlatformInitLib/MemDetect.c | 5 +- > OvmfPkg/OvmfPkg.dec | 1 + > 8 files changed, 114 insertions(+), 2 deletions(-) > > -- > 2.34.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
