2016-06-27cadence_gem: Avoid infinite loops with a misconfigured bufferAlistair Francis
A guest can write zero to the DMACFG resulting in an infinite loop when it reaches the while(bytes_to_copy) loop. To avoid this issue enforce a minimum size for the RX buffer. Hardware does not have this enforcement and relies on the guest to set a non-zero value.

2016-06-24virtio-bus: common ioeventfd infrastructureCornelia Huck
Introduce a set of ioeventfd callbacks on the virtio-bus level that can be implemented by the individual transports. At the virtio-bus level, do common handling for host notifiers (which is actually most of it). Two things of note: - When setting the host notifier, we only switch from/to the generic ioeventfd handler. This fixes a latent bug where we had no ioeventfd assigned for a certain window. - We always iterate over all possible virtio queues, even though ccw (currently) has a lower limit. It does not really matter here.

2016-06-24pc: acpi: drop intermediate PCMachineState.node_cpuIgor Mammedov
PCMachineState.node_cpu was used for mapping APIC ID to numa node id as CPU entries in SRAT used to be built on sparse APIC ID bitmap (up to apic_id_limit). However since commit 5803fce pc: acpi: SRAT: create only valid processor lapic entries CPU entries in SRAT aren't build using apic bitmap but using 0..maxcpus index instead which is also used for creating numa_info[x].node_cpu map. So instead of doing useless intermediate conversion from 1. node by cpu index -> node by apic id i.e. numa_info[x].node_cpu -> PCMachineState.node_cpu 2. apic id -> srat entry PMX PCMachineState.node_cpu[apic id] -> PMX value use numa_info[x].node_cpu map directly like ARM does and do 1. numa_info[x].node_cpu -> PMX value using index in range 0..maxcpus and drop not necessary PCMachineState.node_cpu and related code. That also removes the last (not counting legacy hotplug) dependency of ACPI code on apic_id_limit and need to allocate huge sparse PCMachineState.node_cpu array in case of 32-bit APIC IDs.

2016-06-24pc: use new CPU hotplug interface since 2.7 machine typeIgor Mammedov
For compatibility reasons PC/Q35 will start with legacy CPU hotplug interface by default but with new CPU hotplug AML code since 2.7 machine type. That way legacy firmware that doesn't use QEMU generated ACPI tables will be able to continue using legacy CPU hotplug interface. While new machine type, with firmware supporting QEMU provided ACPI tables, will generate new CPU hotplug AML, which will switch to new CPU hotplug interface when guest OS executes its _INI method on ACPI tables loading.

2016-06-22memory: Add reporting of supported page sizesAlexey Kardashevskiy
Every IOMMU has some granularity which MemoryRegionIOMMUOps::translate uses when translating, however this information is not available outside the translate context for various checks. This adds a get_min_page_size callback to MemoryRegionIOMMUOps and a wrapper for it so IOMMU users (such as VFIO) can know the minimum actual page size supported by an IOMMU. As IOMMU MR represents a guest IOMMU, this uses TARGET_PAGE_SIZE as fallback. This removes vfio_container_granularity() and uses new helper in memory_region_iommu_replay() when replaying IOMMU mappings on added IOMMU memory region.
