Date: Thu, 24 Mar 2022 12:20:21 -0700 From: Michael Kelley <mikelley@...rosoft.com> To: Jason@...c4.com, tytso@....edu, ardb@...nel.org, andy.shevchenko@...il.com, hdegoede@...hat.com, graf@...zon.com, rafael@...nel.org, linux-kernel@...r.kernel.org Cc: mikelley@...rosoft.com Subject: [PATCH 1/1] 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.
