It is not possible to set the compat property to an unknown value with
powerpc_set_compat(). Something must have gone terribly wrong in QEMU,
if we detect an "Internal error" in powerpc_get_compat(). Let's abort then.
This patch also drops the "max_compat ? *max_compat : -1" construct. It is
useless since max_compat is dereferenced a few lines above.

If CPU core addition or removal is allowed in random order leading to
holes in the core id range (and hence in the cpu_index range), migration
can fail as migration with holes in cpu_index range isn't yet handled
correctly.
Prevent this situation by enforcing the addition in contiguous order
and removal in LIFO order so that we never end up with holes in
cpu_index range.

This ioctl() call to VFIO_IOMMU_SPAPR_TCE_REMOVE was left over from an
earlier version of the code and has since been folded into
vfio_spapr_remove_window().
It wasn't caught because although the argument structure has been removed,
the libc function remove() means this didn't trigger a compile failure.
The ioctl() was also almost certain to fail silently and harmlessly with
the bogus argument, so this wasn't caught in testing.

MacOS uses an architecturally illegal MSR combination that
seems nonetheless supported by 32-bit processors, which is
to have MSR[PR]=1 and one or more of MSR[DR/IR/EE]=0.
This adds support for it. To work properly we need to also
properly include support for PR=1,{I,D}R=0 to the MMU index
used by the qemu TLB.

If the host has 8 threads/core and the guest is started with:
-smp cores=1,threads=4,maxcpus=12
It is possible to crash QEMU by doing:
(qemu) device_add host-spapr-cpu-core,core-id=16,id=foo
(qemu) device_del foo
Segmentation fault
This happens because spapr_core_unplug() assumes cpu_dt_id == core_id.
As long as cpu_dt_id is derived from the non-table cpu_index, this is
only true when you plug cores with contiguous ids.
It is safer to be consistent: the DR connector was created with an
index that is immediately written to cc->core_id, and spapr_core_plug()
also relies on cc->core_id.
Let's use it also in spapr_core_unplug().

this is the first step in reducing the brk heap fragmentation
created by the map->nodes memory allocation. Since the introduction
of RCU the freeing of the PhysPageMaps is delayed so that sometimes

Even worse the memory for map->nodes is allocated and shortly
afterwards reallocated. Since the number of nodes it grows
to in the end is the same for all PhysPageMaps remember this value
and at least avoid the reallocation.
The large number of simultaneous allocations (about 450 x 70kB in

GIC the guest is using. To be consistent and improve SGI efficiency
we make the same adjustments for TCG as 64-bit KVM hosts. We neglect
to add consistency with 32-bit KVM hosts, as that would reduce SGI

As MPIDR is a system register, and thus guest visible, we only make

qemu-system-aarch64: migration/savevm.c:615:
vmstate_register_with_alias_id:
Assertion `!se->compat || se->instance_id == 0' failed.
The reason is that the vmstate sections for the two scsi-hd devices are
not uniquely identifiable by name.
The direct parent buses of the scsi-hd devices -- scsi0.0 and scsi1.0 --
support the BusClass.get_dev_path member function. scsibus_get_dev_path()
formats a device path prefix with the help of its topologically parent
bus, and then appends the chan🆔lun triplet to it. For both scsi-hd
devices, this triplet is 0:0:0.
(Here we use "device path" in the QEMU migration sense, for vmstate
section identification, not in the OFW or UEFI device path senses.)
The virtio-scsi HBA is plugged into the virtio-mmio bus (implemented by
the internal VirtIOMMIOProxy device). This bus class
(TYPE_VIRTIO_MMIO_BUS) inherits, as its get_dev_path() member function,
the virtio_bus_get_dev_path() method from its parent class
(TYPE_VIRTIO_BUS).
virtio_bus_get_dev_path() does not format any kind of device address on
its own; "virtio addresses" are transport-specific. Therefore
virtio_bus_get_dev_path() asks the topologically parent bus of the proxy
object (implementing the specific virtio transport) to format the address
of the proxy object.
(For virtio-pci devices (where the proxy is an instance of VirtIOPCIProxy,
plugged into a PCI bus), this ends up in pcibus_get_dev_path().)
However, VirtIOMMIOProxy is usually (in practice: always) plugged into
"main-system-bus", the singleton TYPE_SYSTEM_BUS object. This BusClass
does not support formatting QEMU vmstate device paths at all (as
SysBusDevice objects can have zero or more IO ports and zero or more MMIO
regions). Hence the formatting request delegated from
virtio_bus_get_dev_path() gets answered with NULL.
The end result is that the two scsi-hd devices end up with the same device
path "0:0:0", which triggers the assert.
We can solve this by recognizing that virtio-mmio transports are
distinguished from each other by their base addresses in MMIO address
space. Implement virtio_mmio_bus_get_dev_path() as follows:
(1) The virtio device whose devpath is to be formatted resides on a
virtio-mmio bus that is implemented by a VirtIOMMIOProxy object. Ask
the parent bus of VirtIOMMIOProxy to format the device path of
VirtIOMMIOProxy, as a path prefix. (This is identical to what
virtio_bus_get_dev_path() does.)
(2) Append the base address of VirtIOMMIOProxy to the device path, such
as:
- virtio-mmio@000000000a003e00,
- virtio-mmio@000000000a003c00.
Given that these device paths are placed in the migration stream, step (2)
above, if done unconditionally, would break migration. So make that step
conditional on a new VirtIOMMIOProxy property, which is enabled for 2.7
machine types and later.

FLASH chip on XTFPGA boards is connected with 16-bit-wide interface.
Latest U-Boot can see the difference and does not work correctly with
32-bit-wide interface.

iotest 157 pretends not to care about the image format used, but in fact
it does due to the format name not being filtered in its output. This
patch adds filtering and changes the reference output accordingly.

First, bdrv_open_child() expects all options for the child to be
prefixed by the child's name (and a separating dot). Second,
bdrv_open_child() does not take ownership of the QDict passed to it but
only extracts all options for the child, so if a QDict is created for
the sole purpose of passing it to bdrv_open_child(), it needs to be
freed afterwards.
This patch makes vvfat adhere to both of these rules.

Currently, the output of 'info snapshots' shows fully available snapshots.
It's opaque, hides some snapshot information to users. It's not convenient
if users want to know more about all of snapshot information on every block
device via monitor.
Follow Kevin's and Max's proposals, The patch makes the output more detailed:
(qemu) info snapshots
List of snapshots present on all disks:
ID TAG VM SIZE DATE VM CLOCK
-- checkpoint-1 165M 2016-05-22 16:58:07 00:02:06.813
List of partial (non-loadable) snapshots on 'drive_image1':

Currently qemu uses snapshot id to determine whether a snapshot is fully
available, It causes incorrect output in some scenario.
For instance:
(qemu) info block
drive_image1 (#block113): /opt/vms/SLES12-SP1-JeOS-x86_64-GM/disk0.qcow2
(qcow2)
Cache mode: writeback
drive_image2 (#block349): /opt/vms/SLES12-SP1-JeOS-x86_64-GM/disk1.qcow2
(qcow2)
Cache mode: writeback
(qemu)
(qemu) info snapshots
There is no snapshot available.
(qemu)
(qemu) snapshot_blkdev_internal drive_image1 snap1
(qemu)
(qemu) info snapshots
There is no suitable snapshot available
(qemu)
(qemu) savevm checkpoint-1
(qemu)
(qemu) info snapshots
ID TAG VM SIZE DATE VM CLOCK
1 snap1 0 2016-05-22 16:57:31 00:01:30.567
(qemu)
$ qemu-img snapshot -l disk0.qcow2
Snapshot list:
ID TAG VM SIZE DATE VM CLOCK
1 snap1 0 2016-05-22 16:57:31 00:01:30.567
2 checkpoint-1 165M 2016-05-22 16:58:07 00:02:06.813
$ qemu-img snapshot -l disk1.qcow2
Snapshot list:
ID TAG VM SIZE DATE VM CLOCK
1 checkpoint-1 0 2016-05-22 16:58:07 00:02:06.813
The patch uses snapshot name instead of snapshot id to determine whether a
snapshot is fully available and uses '--' instead of snapshot id in output
because the snapshot id is not guaranteed to be the same on all images.
For instance:
(qemu) info snapshots
List of snapshots present on all disks:
ID TAG VM SIZE DATE VM CLOCK

Throttling groups are named using the 'group' parameter of the
block_set_io_throttle command and the throttling.group command-line
option. If that parameter is unspecified the groups get the name of
the block device.
This patch adds a new test to check the naming of throttling groups.
