Iglesias" Enable PCI on the ARM PVH machine. First we add a way to control the use of buffered IOREQ's since those are not supported on Xen/ARM. Finally we enable the PCI support. I've published some instructions on how to try this including the work in progress Xen side of the PVH PCI support: https://github.com/edgarigl/docs/blob/master/xen/pvh/virtio-pci-dom0less.md Cheers, Edgar ChangeLog: v1 -> v2: * Change handle_ioreq from int to uint8_t. * Fallback to legacy API if buffered ioreqs are enabled and also if the new API is not supported. Clarify with comments. Edgar E.
