This patchset exploits the VFIO ZPCI CLP region, which provides hardware information about passed-through s390 PCI devices that can be shared with the guest. The retrieval of this information is done once per function (and for a subset of data, once per function group) and is performed at time of device plug. Some elements provided in the CLP region must still be forced to default values for now to reflect what QEMU actually provides support for. The original work for this feature was done by Pierre Morel. Note: This patchset will overlap with "s390x/pci: Accomodate vfio DMA limiting" because they both add hw/s390x/s390-pci-vfio.* - This is intentional as both patchsets add functionality that belongs in these new files. Once one set is taken, I'll rebase the other on top of it.
