[PATCH v2 0/3] Viridian changes for Hyper-V as a guest

Posted by Ross Lagerwall 2 weeks, 6 days ago

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
