From 0396e46dc46523cba8401a0df84f67cc0b6067ab Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Thu, 24 Mar 2022 12:20:21 -0700 Subject: virt: vmgenid: recognize new CID added by Hyper-V In the Windows spec for VM Generation ID, the originally specified CID is longer than allowed by the ACPI spec. Hyper-V has added "VMGENCTR" as a second valid CID that is conformant, while retaining the original CID for compatibility with Windows guests. Add this new CID to the list recognized by the driver.
