Fwd: VT-d2 support inside Linux kernel

Hi,

I think since this work is marked WIP in Linux kernel on current KVM
TODO list. This might be a better list to ask questions.

So, in current top of tree, I am seeing some ats support for
intel-iommu. Does that mean the ATS part is already finished?
Basically, I would like to know the current status of VT-d2 support,
anything left?

Thanks,
CJ

Hi,

Is there any information I can find about VT-d2 support inside Linux
kernel? It was marked as WIP on KVM todo list. In current top of tree,
I am seeing some ats support for intel-iommu. Does that mean the ATS
part is already finished?
