Subject: [PATCH v13 11/12] EFI: Introduce the new AMD Memory Encryption GUID.
Date: Thu, 15 Apr 2021 15:58:42 +0000	[thread overview]
Message-ID: <ae8924d0dcac0b397295f53f7bd3ff06f6a9ff12.1618498113.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1618498113.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.
