Subject: [PATCH v1 0/2] Viridian changes for Hyper-V as a guest
Date: Fri, 28 Aug 2026 14:11:40 +0100	[thread overview]
Message-ID: <20260828131142.3986110-1-ross.lagerwall@citrix.com> (raw)

Hi,

Here are two 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
