2016-07-25hw/ppc/spapr: Make sure to close the htab_fd when migration is canceledThomas Huth
When canceling a migration process, we currently do not close the HTAB migration file descriptor since htab_save_complete() is never called in that case. So we leave the migration process with a dangling htab_fd value around, and this causes any further migration attempts to fail. To fix this issue, simply make sure that the htab_fd is closed during the migration cleanup stage. And since the cleanup() function is also called when migration succeeds, we can also remove the call to close_htab_fd() from the htab_save_complete() function.

2016-07-21intel_iommu: add support for split irqchipPeter Xu
In split irqchip mode, IOAPIC is working in user space, only update kernel irq routes when entry changed. When IR is enabled, we directly update the kernel with translated messages. It works just like a kernel cache for the remapping entries. Since KVM irqfd is using kernel gsi routes to deliver interrupts, as long as we can support split irqchip, we will support irqfd as well. Also, since kernel gsi routes will cache translated interrupts, irqfd delivery will not suffer from any performance impact due to IR. And, since we supported irqfd, vhost devices will be able to work seamlessly with IR now. Logically this should contain both vhost-net and vhost-user case.

To enable interrupt remapping for intel IOMMU device, each IOAPIC device in the system reported via ACPI MADT must be explicitly enumerated under one specific remapping hardware unit. This patch adds the root-complex IOAPIC into the default DMAR device. Please refer to VT-d spec 8.3.1.1 for more information. Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

2016-07-20intel_iommu: allow queued invalidation for IRPeter Xu
Queued invalidation is required for IR. This patch add basic support for interrupt cache invalidate requests. Since we currently have no IR cache implemented yet, we can just skip all interrupt cache invalidation requests for now. Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

2016-07-20x86-iommu: introduce "intremap" propertyPeter Xu
Adding one property for intel-iommu devices to specify whether we should support interrupt remapping. By default, IR is disabled. To enable it, we should use (take Intel IOMMU as example): -device intel_iommu,intremap=on This property can be shared by Intel and future AMD IOMMUs.
