...for us, at least in the short term. It would take the same effort to define a powerpc-specific hypercall to accomplish the same thing (easier, in fact since we wouldn't have to implement the rest of virtio-iommu). In fact, there already is such hypercall, but it is only defined for VIO devices (RTAS_IBM_SET_TCE_BYPASS in QEMU). We would have to make it work on virtio devices as well. -- Thiago Jung Bauermann IBM Linux Technology Center
