RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 Intel's Trust Domain Extensions (Intel TDX) refers to an Intel technology that extends Virtual Machines Extensions (VMX) and Multi-Key Total Memory Encryption (MKTME) with a new kind of virutal machines guest called a Trust Domain (TD). A TD is desinged to run in a CPU mode that protects the confidentiality of TD memory contents and the TD's CPU state from other software, including the hosting Virtual-Machine Monitor (VMM), unless explicitly shared by the TD itself. There are 2 configurations for TDVF to upstream. See below link for the definitions of the 2 configurations. https://edk2.groups.io/g/devel/message/76367 This patch-set is to enable the basic feature of Config-B in OvmfPkg. - Add a standalone IntelTdxX64.dsc to a TDX specific directory for a *full* feature TDVF. (Align with existing SEV) - IntelTdx.dsc includes Tdx/Legacy OVMF basic boot capability. The final binary can run on Tdx/Legacy OVMF. - PEI phase is skipped. By design in Config-B there should be more advanced features, such as: - RTMR based measurement and measure boot. - Remove unnecessary drivers to reduce attack surface, such as network stack. To make the code review more efficiency, Config-B is split into 2 waves: - Basic feature of Config-B - Advanced feature of Config-B This patch contains 2 files (IntelTdxX64.dsc/IntelTdxX64.fdf) which enable the basic feature of Config-B. In the waves of Advanced feature of Config-B, we will re-visit these 2 files. TDX_PEI_LESS_BOOT is defined in IntelTdxX64.dsc to indicate it boots up without PEI phase.
