Passthrough support ?
...ough associated event
channel domU makes
"synchronous" use of this device.
===
Queries:
1. What i am really not so sure about is ... passthrough case
Will there be requirement to map the address space of this PCI
device in domU ? Will the page which was being shared so-far
{xen_pci_sharedinfo}
for emulation , be "flipped" ( transferred ) into domU ? 2. Well ,
Having read the code for linux (dom0,domU) I see that there are split
device drivers for PCI. (pci front and PCIback). Which are normally
communicating over xenbus. which looks almost like other split
drive...
