Subject: [PATCH v8 14/18] EFI: Introduce the new AMD Memory Encryption GUID.
Date: Tue, 5 May 2020 21:20:10 +0000 [thread overview]
Message-ID: <abeea5c7dc54cf86e74bc9d658cef9b25a8fac6e.1588711355.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1588711355.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 enviroment 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.
