From 8c524bedb4328e0545dfe3c651615286c2b5b411 Mon Sep 17 00:00:00 2001 From: Xin Jiang Date: Thu, 17 Aug 2023 09:28:10 +0800 Subject: [PATCH] OvmfPkg/UefiCpuPkg: Support Hygon CSV3 feature CSV3 feature integrates secure processor, memory encryption and memory isolation to provide the ability to protect guest's private data. The CSV guest's context like CPU registers, control block and nested page table is accessed only by the guest itself and the secure processor. Neither other guests nor the host can tamper with the guest's context.
