Subject: [PATCH v10 13/16] EFI: Introduce the new AMD Memory Encryption GUID.
Date: Thu, 4 Feb 2021 00:40:01 +0000 [thread overview]
Message-ID: <301a3078f4604e23d8c2c5a2e1d4804a3b15dffa.1612398155.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1612398155.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.
