508e038a5d dtc: Revert unintentional submodule downgrade from commit 077dd74239
Commit 077dd74239 inadvertently downgraded the 'dtc' submodule,
undoing the increment added in commit 6e85fce022. Revert this,
returning the submodule state to where we should be.

ab711e216b ppc patch queue for 2017-03-01
I was hoping to get this pull request squeezed in before the soft
 freeze, but I ran into some difficulties during testing.  Everything
 here was at least posted before the soft freeze, so I'm hoping we can
 still merge it for 2.9.
 
 The biggest things here are:
     * Cleanups to handling of hashed page tables, that will make
       adding support for the POWER9 MMU easier
     * Cleanups to the XICS interrupt controller that will make
       implementing the powernv machine easier
     * TCG implementation of extended overflow and carry handling for
       POWER9
 
 It also includes:
     * Increasing the CPU limit for pseries to 1024 vCPUs
     * Generating proper OF node names in qemu (making hotplug and
       coldplug logic closer together)

96a8821d21 virtio: unbreak virtio-pci with IOMMU after caching ring translations
Commit c611c76417 ("virtio: add MemoryListener to cache ring
translations") registers a memory listener to dma_as. This may not
work when IOMMU is enabled: dma_as(bus_master_as) were initialized in
pcibus_machine_done() after virtio_realize(). This will cause a
segfault. Fixing this by using pci_device_iommu_address_space()
instead to make sure address space were initialized at this time.

With this fix, IOMMU device were required to be initialized before any
virtio-pci devices.

874adf45db virtio: add missing region cache init in virtio_load()
Commit 97cd965c07 ("virtio: use
VRingMemoryRegionCaches for avail and used rings") switched to a memory
region cache to avoid repeated map/unmap operations.

The virtio_load() process is a little tricky because vring addresses are
serialized in two separate places.  VIRTIO 1.0 devices serialize desc
and then a subsection with used and avail.  Legacy devices only
serialize desc.

Live migration of VIRTIO 1.0 devices fails on the destination host with:

  VQ 0 size 0x80 < last_avail_idx 0x12f8 - used_idx 0x0
  Failed to load virtio-blk:virtio
  error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk'

This happens because the memory region cache is only initialized after
desc is loaded and not after the used and avail subsection is loaded.
If the guest chose memory addresses that don't match the legacy ring
layout then the wrong guest memory location is accessed.

Wait until all ring addresses are known before trying to initialize the
region cache.  Also clarify the incomplete comment about VIRTIO-1 ring
address subsection.

34c6bf22a8 virtio: guard vring access when setting notification
Switching to vring caches exposed an existing bug in
virtio_queue_set_notification(): We can't access vring structures
if they have not been set up yet. This may happen, for example,
for virtio-blk devices with multiple queues: The code will try to
switch notifiers for every queue, but the guest may have only set up
a subset of them.

Fix this by guarding access to the vring memory by checking for
vring.desc. The first aio poll will iron out any remaining
inconsistencies for later-configured queues (buggy legacy drivers).

bcf19777df audio/sdlaudio: Allow audio playback with SDL2
When compiling with SDL2, the semaphore trick used in sdlaudio.c
does not work - QEMU locks up completely in this case. To avoid
the hang and get at least some audio playback up and running (it's
a little bit crackling, but better than nothing), we can use the
SDL locking functions SDL_LockAudio() and SDL_UnlockAudio() to sync
with the sound playback thread instead.

1ffc266539 audio: make audio poll timer deterministic
This patch changes resetting strategy of the audio polling timer.
It does not change expiration time if the timer is already set.
This patch is needed to make this timer deterministic and to use execution
record/replay for audio devices.

audio_reset_timer is used in the function audio_vm_change_state_handler.
Therefore every time VM is stopped or restarted the timer will be reset
to new timeout. Virtual clock does not proceed while VM is stopped.
Therefore there is no need in resetting the timeout when VM restarts.

a starting point for creating your own guest.

Two sample configuration files are provided:

  * mach-virt-graphical.cfg can be used to start a
    fully-featured (USB, graphical console, etc.)
    guest that uses VirtIO devices;

  * mach-virt-serial.cfg is similar but has a minimal
    set of devices and uses the serial console.

All configuration files are fully commented and neatly

Instead of having a single sample configuration file,
we now have several:

  * q35-emulated.cfg documents the default devices QEMU
    adds to a q35 guest and the additional devices that
    are pretty much guaranteed to be present in a
    physical q35-based machine;

  * q35-virtio-graphical.cfg can be used to start a
    fully-featured (USB, graphical console, audio, etc.)
    guest that uses VirtIO instead of emulated devices;

  * q35-virtio-serial.cfg is similar but has a minimal
    set of devices and uses the serial console.

All configuration files are fully commented and neatly

675f22c6d3 bus: do not unref hotplug handler
Apparently, none of the bus owner give a reference to the hotplug
handler property, do not unref it on bus release.

Furthermore, a bus is allowed to be its own hotplug handler, which can
be seen in qbus_set_bus_hotplug_handler() function. However, in this
case, the reference can't be given to the property, or this will create
a cyclic dependency and the bus will never be free.

Each bus owner should manage the lifecycle of the hotplug handler.
