Subject: [PATCH 3/4] EFI: Introduce the new AMD Memory Encryption GUID.
Date: Thu, 22 Apr 2021 20:56:39 +0000 [thread overview]
Message-ID: <eadc5fbf90e02fa4955f66f0d62661ed781c3dbd.1619124613.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1619124613.git.ashish.kalra@amd.com>
From: Ashish Kalra <ashish.kalra@amd.com>
Introduce a new AMD Memory Encryption GUID which is currently
used for defining a new UEFI environment variable which indicates
UEFI/OVMF support for the SEV live migration feature. This variable
is setup when UEFI/OVMF detects host/hypervisor support for SEV
live migration and later this variable is read by the kernel using
EFI runtime services to verify if OVMF supports the live migration
feature.
