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 below features of Config-B in OvmfPkg. - Enable RTMR based measurement and measured boot - Install CC_MEASUREMENT_PROTOCOL instance in Td guest The measurement for the other components, such as kernel image, initrd, will be introduced in the following patch-sets. Patch 1: HashLibTdx provides SHA384 service and extend to RTMR registers. Patch 2: SecCryptLib is the cryptographic library instance for SEC. Patch 3 - 8: These 6 patches are related to RTMR based measurement and CC Eventlog ACPI table. Patch 9: Update IntelTdxX64.dsc/IntelTdxX64.fdf to support RTMR based measurement and measured boot. Code at: https://github.com/mxu9/edk2/tree/tdvf_wave4.v3 v3 changes: - Refine HashLibBaseCryptoRouterTdx to HashLibTdx - Add NULL version algorithms in SecCryptLib. - Add SecMeasurementLib which does the measurement in SEC phase. - Rebase EDK2 code base. (commit: 91a03f78ba) v2 changes: - Move the definition of EFI_CC_EVENT_HOB_GUID from MdePkg to SecurityPkg. - Update the definition of EFI_CC_EVENTLOG_ACPI_TABLE based on below discussion: https://edk2.groups.io/g/devel/message/87396 https://edk2.groups.io/g/devel/message/87402 - Update the code base to 94f905b3bf.
