[edk2-devel] [PATCH ovmf v4 0/5] Enable AMD SEV-ES DebugVirtualization

["Alexey Kardashevskiy via groups.io" <aik=amd.com@groups.io>]

This is to prevent #DB interception on SEV-ES VM with
enabled DebugVirtualization feature.

The previous conversation is here:
https://edk2.groups.io/g/devel/topic/patch_ovmf_v3_0_5_enable/105863808

This is based on sha1

Please comment. Thanks.
