[edk2-devel] [PATCH 0/7] Add VirtMmCommunication driver, enable for OVMF and ArmVirt.

["Gerd Hoffmann" <kraxel@redhat.com>]

This is the edk2 side of the qemu patch series posted last week to
qemu-devel:
  https://lists.gnu.org/archive/html/qemu-devel/2023-11/msg03714.html

The driver forwards MM calls to the virtualization host instead of the
MM code running in SMM (x64) or el3 (arm) mode.  The functionality
traditionally implemented by the SMM code is provided by qemu instead.

This allows to provide persistent variable support without an
(virtual) flash device and it also allows to support secure
boot without depending on SMM or el3 emulation support in the
hypervisor.

take care,
  Gerd
