Thanks, Sean!
Please do make an official stable tag that I can use for coordinating
the initial TDX Connect enabling series. While there is no strict
dependency I do not want it to be the case that a bisect of TDX Connect
bounces between a world where you need to load kvm_intel before the PCI
layer can do link encryption operations and keep it loaded etc.
My proposal, unless you or Dave holler, is to take the first round of
TDX Connect enabling through the tsm.git tree with acks. This round does
not have kvm entanglements, i.e. IOMMU coordination and device
assignment come later. It also does not have much in the way of core x86
entanglements beyond new seamcall exports.
