From: Sebastien Boeuf <sebastien.bo...@intel.com> The IntelTdxX64 OVMF target wasn't working with Cloud Hypervisor on TDX platform. 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.
