From d8575c6c0242bb1457589111e879f46348704534 Mon Sep 17 00:00:00 2001 From: Brijesh Singh <brijesh.singh@amd.com> Date: Thu, 8 Mar 2018 06:48:44 -0600 Subject: sev/i386: add command to initialize the memory encryption context When memory encryption is enabled, KVM_SEV_INIT command is used to initialize the platform. The command loads the SEV related persistent data from non-volatile storage and initializes the platform context. This command should be first issued before invoking any other guest commands provided by the SEV firmware.
