The VBD and VNIF frontend driver can then be used in=20 unmodified kernel as a module to get better performance than device = model. The backend driver needs no change and can work together with = xeno-linux. The event channel mechanism works as a pci device in guest linux, so a event channel device driver will as basic module in guest kernel. What's the patch done is: 1.copy_to/from_guest support, which is used to copy context from/to=20 guest space to hypervisor space. 2.copy_to/from_user will call copy_to/from_guest for a vmx domain. 3.A separate hypercall table for paravirutulization driver which mask some unused entries. 4.add hypercalls for address translation.and share page mapping(event=20 channel and grant table) 5.clean some hypercalls path for vmx domain. ------_=_NextPart_001_01C55CF1.0162A417 Content-Type: text/x-patch; name="paravirtulization-driver-hypervisor.patch" Content-Transfer-Encoding: base64
