Re: [Xen-devel] Re: PCI Passthrough using GART on AMD CPUs?

Hi,

I've found an old post about GART as mini-IOMMU. Please see below.
As far as I read, the patch was not checked in because it was not
complete. If the code comes to the main tree, there is no reason
we don't support PCI hotplug for GART.

Thanks,
