Sorry, I don't have a handy pointer. You can search for either pv dma changes (paravirtualizing the guest's request for dma addrs so that it gets host physical addr to program card for dma) or reserved-ram for pci-passthrough (1:1 mapping of guest to host physical memory). I don't recall a recent attempt to bring them forward, so expect anything you find to be quite stale. thanks, -chris
