2015-01-12kvm: extend kvm_irqchip_add_msi_route to work on s390Frank Blaschka
on s390 MSI-X irqs are presented as thin or adapter interrupts for this we have to reorganize the routing entry to contain valid information for the adapter interrupt code on s390. To minimize impact on existing code we introduce an architecture function to fixup the routing entry.

2015-01-12s390: implement pci instructionsFrank Blaschka
This patch implements the s390 pci instructions in qemu. It allows to access and drive pci devices attached to the s390 pci bus. Because of platform constrains devices using IO BARs are not supported. Also a device has to support MSI/MSI-X to run on s390.

2015-01-12s390: Add PCI bus supportFrank Blaschka
This patch implements a pci bus for s390x together with infrastructure to generate and handle hotplug events, to configure/unconfigure via sclp instruction, to do iommu translations and provide s390 support for MSI/MSI-X notification processing.

2015-01-09vfio-pci: Fix interrupt disablingAlex Williamson
When disabling MSI/X interrupts the disable functions will leave the device in INTx mode (when available). This matches how hardware operates, INTx is enabled unless MSI/X is enabled (DisINTx is handled separately). Therefore when we really want to disable all interrupts, such as when removing the device, and we start with the device in MSI/X mode, we need to pass through INTx on our way to being completely quiesced. In well behaved situations, the guest driver will have shutdown the device and it will start vfio_exitfn() in INTx mode, producing the desired result. If hot-unplug causes the guest to crash, we may get the device in MSI/X state, which will leave QEMU with a bogus handler installed. Fix this by re-ordering our disable routine so that it should always finish in VFIO_INT_NONE state, which is what all callers expect. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2015-01-09vfio-pci: Fix BAR size overflowAlex Williamson
We use an unsigned int when working with the PCI BAR size, which can obviously overflow if the BAR is 4GB or larger. This needs to change to a fixed length uint64_t. A similar issue is possible, though even more unlikely, when mapping the region above an MSI-X table. The start of the MSI-X vector table must be below 4GB, but the end, and therefore the start of the next mapping region, could still land at 4GB.

This used_length size can change across reboots. Follow up patches will change used_length for such blocks at migration, making it easier to extend devices using such RAM (notably ACPI, but in the future thinkably other ROMs) without breaking migration compatibility or wasting ROM (guest) memory. Device is notified on resize, so it can adjust if necessary. Note: nothing prevents making all RAM resizeable in this way.

2015-01-07PPC: Fix crash on spapr_tce_table_finalize()David Gibson
spapr_tce_table_finalize() can SEGV if the object was not previously realized. In particular this can be triggered by running qemu-system-ppc -device spapr-tce-table,? The basic problem is that we have mismatched initialization versus finalization: spapr_tce_table_finalize() is attempting to undo things that are done in spapr_tce_table_realize(), not an instance_init function. Therefore, replace spapr_tce_table_finalize() with spapr_tce_table_unrealize().
