2016-09-27cpus: pass CPUState to run_on_cpu helpersAlex Bennée
CPUState is a fairly common pointer to pass to these helpers. This means if you need other arguments for the async_run_on_cpu case you end up having to do a g_malloc to stuff additional data into the routine. For the current users this isn't a massive deal but for MTTCG this gets cumbersome when the only other parameter is often an address. This adds the typedef run_on_cpu_func for helper functions which has an explicit CPUState * passed as the first parameter. All the users of run_on_cpu and async_run_on_cpu have had their helpers updated to use CPUState where available.

Migrating a VM during reboot sometimes results in differences between the source and destination in the SMRAM area. This is because migration_bitmap_sync() only fetches from KVM the dirty log of address_space_memory. SMRAM memory slots are ignored and the modifications to SMRAM are not sent to the destination.

2016-09-27memory: introduce IOMMUNotifier and its capsPeter Xu
IOMMU Notifier list is used for notifying IO address mapping changes. Currently VFIO is the only user. However it is possible that future consumer like vhost would like to only listen to part of its notifications (e.g., cache invalidations). This patch introduced IOMMUNotifier and IOMMUNotfierFlag bits for a finer grained control of it. IOMMUNotifier contains a bitfield for the notify consumer describing what kind of notification it is interested in. Currently two kinds of notifications are defined: - IOMMU_NOTIFIER_MAP: for newly mapped entries (additions) - IOMMU_NOTIFIER_UNMAP: for entries to be removed (cache invalidates) When registering the IOMMU notifier, we need to specify one or multiple types of messages to listen to. When notifications are triggered, its type will be checked against the notifier's type bits, and only notifiers with registered bits will be notified. (For any IOMMU implementation, an in-place mapping change should be notified with an UNMAP followed by a MAP.)

2016-09-23virtio: use unsigned int for virtqueue_get_avail_bytes() indexStefan Hajnoczi
The virtio code uses int, unsigned int, and uint16_t for virtqueue indices. The uint16_t is used for the low-level descriptor layout in virtio_ring.h while code that isn't concerned with descriptor layout can use unsigned int. Use of int is problematic because it can result in signed/unsigned comparison and incompatible int*/unsigned int* pointer types. Make the virtqueue_get_avail_bytes() 'i' variable unsigned int. This eliminates the need to introduce casts and modify code further in the patches that follow.

2016-09-23virtio: stop virtqueue processing if device is brokenStefan Hajnoczi
QEMU prints an error message and exits when the device enters an invalid state. Terminating the process is heavy-handed. The guest may still be able to function even if there is a bug in a virtio guest driver. Moreover, exiting is a bug in nested virtualization where a nested guest could DoS other nested guests by killing a pass-through virtio device. I don't think this configuration is possible today but it is likely in the future. If the broken flag is set, do not process virtqueues or write back used descriptors. The broken flag can be cleared again by resetting the device. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Cornelia Huck <cornelia.huck@de.ibm.com> Reviewed-by: Michael S.

2016-09-23block: Remove BB interface from blockdev-add/delKevin Wolf
With this patch, blockdev-add always works on a node level, i.e. it creates a BDS, but no BB. Consequently, x-blockdev-del doesn't need the 'device' option any more, but 'node-name' becomes mandatory. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2016-09-23qemu-iotests/141: Avoid blockdev-add with idKevin Wolf
We want to remove the 'id' option for blockdev-add. This removes one user of the option and makes it use only node names. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2016-09-23block: Avoid printing NULL string in error messagesKevin Wolf
Even for nodes that have a BlockBackend attached, bdrv_get_parent_name() can return NULL if the BB is anonymous (e.g. it belongs to a block job or a device that was created with a drive=<node-name> option). Remove the information from the error message. The user probably knows already why the node is still in use. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2016-09-23qemu-iotests/139: Avoid blockdev-add with idKevin Wolf
We want to remove the 'id' option for blockdev-add. This removes one user of the option and makes it use only node names. Some test cases that used to work with an unattached BlockBackend are removed, either because they don't make sense with an attached device or because the equivalent test case with an attached device already exists.

We want to remove the 'id' option for blockdev-add. This removes one user of the option and makes it use only node names. The test cases that test conflicts between the 'id' option to blockdev-add and existing block devices or the 'node-name' of the same command can be removed because it won't be possible to specify this at the end of the series.

We want to remove the 'id' option for blockdev-add. This removes one user of the option and makes it use only node names. In order to keep the test meaningful, some instances of query-block that want to check whether the node still exists and would now turn up empty must be converted to query-named-block-nodes (which also return the protocol level node, but that shouldn't hurt).
