- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
Hello,
Just two patches remaining, and the last one is already Acked.
First patch deals with moving the switching of SSBD from guest
vm{entry,exit} to vCPU context switch, and lets Xen run with the guest
SSBD selection under some circumstances by default.
Andrew has expressed reservations to me privately with patch 2/2, but
I'm still sending it so that comments can be made publicly (or the patch
applied).
Thanks, Roger.

amd/virt_ssbd: set SSBD at vCPU context switch
amd: remove VIRT_SC_MSR_HVM synthetic feature
