Subject: [PATCH v2 0/3] Viridian changes for Hyper-V as a guest
Date: Fri,  4 Sep 2026 15:15:13 +0100	[thread overview]
Message-ID: <20260904141516.367862-1-ross.lagerwall@citrix.com> (raw)

Hi,

Here are some changes to get the existing Virdian enlightenments working
when running a Windows 11 guest with Hyper-V enabled

Hyper-V also depends on some unimplemented MSRs to boot, but that will
be addressed in a separate series.

Thanks,
Ross
