And use it instead of reaching out to the machine. This allows to get rid
of a call to qdev_get_machine() and to reduce the scope of another one so
that it is only used within the argument list of error_append_hint(). This
is an acceptable tradeoff compared to all it would require to know about
the maximum number of CPUs here without calling qdev_get_machine().

Now that the spapr and pnv machines do set the "xive-fabric" link, the
use of the XIVE fabric pointer becomes mandatory. This is checked with
an assert() in a new realize hook. Since the XIVE router is realized at
machine init for the all the machine's life time, no risk to abort an
already running guest (ie. not a hotplug path).
This gets rid of a qdev_get_machine() call.

In order to get rid of qdev_get_machine(), first add a pointer to the
XIVE fabric under the XIVE router and make it configurable through a
QOM link property.
Configure it in the spapr and pnv machine. In the case of pnv, the XIVE
routers are under the chip, so this is done with a QOM alias property of
the POWER9 pnv chip.

spapr_match_nvt() is a XIVE operation and is used by the machine to
look for a matching target when an event notification is being
delivered. An assert checks that spapr_match_nvt() is called only when
the machine has selected the XIVE interrupt mode but it is redundant
with the XIVE_PRESENTER() dynamic cast.
Apply the cast to spapr->active_intc and remove the assert.

The number of CPU chips of the powernv machine is configurable through a
"num-chips" property. This doesn't fit well with the CPU topology, eg.
some configurations can come up with more CPUs than the maximum of CPUs
set in the toplogy. This causes assertion to be hit with mttcg:
-machine powernv,num-chips=2 -smp cores=2 -accel tcg,thread=multi
ERROR:
tcg/tcg.c:789:tcg_register_thread: assertion failed: (n < ms->smp.max_cpus)
Aborted (core dumped)
Mttcg mandates the CPU topology to be dimensioned to the actual number
of CPUs, depending on the number of chips the user asked for. That is,
'-machine num-chips=N' should always have a '-smp' companion with a
topology that meats the resulting number of CPUs, typically
'-smp sockets=N'.
It thus seems that "num-chips" doesn't bring anything but forcing the user
to specify the requested number of chips on the command line twice. Simplify
the command line by computing the number of chips based on the CPU topology
exclusively. The powernv machine isn't a production thing ; it is mostly
used by developpers to prepare the bringup of real HW. Because of this and
for simplicity, this deliberately ignores the official deprecation process
and dumps "num-chips" right away : '-smp sockets=N' is now the only way to
control the number of CPU chips.
This is done at machine init because smp_parse() is called after instance
init.

A pseries guest can be run as a secure guest on Ultravisor-enabled
POWER platforms. When such a secure guest is reset, we need to
release/reset a few resources both on ultravisor and hypervisor side.
This is achieved by invoking this new ioctl KVM_PPC_SVM_OFF from the
machine reset path.
As part of this ioctl, the secure guest is essentially transitioned
back to normal mode so that it can reboot like a regular guest and
become secure again.
This ioctl has no effect when invoked for a normal guest. If this ioctl
fails for a secure guest, the guest is terminated.

Hi,
QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.
There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.
The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.

Hi,
With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
vhost-user devices can be handled today, they are expected to
restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer
1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.
2) needs ad-hoc code for each helper, but is simple and working
3) is complicated for management layer, QEMU has the migration timing
The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.
Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)
D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages. (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)
dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

Merge remote-tracking branch 'remotes/elmarco/tags/dbus-vmstate7-pull-request' into staging
Add dbus-vmstate
Hi,
With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
vhost-user devices can be handled today, they are expected to
restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer
1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.
2) needs ad-hoc code for each helper, but is simple and working
3) is complicated for management layer, QEMU has the migration timing
The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.
Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)
D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages. (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)
dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

Before the patch, seg_max parameter was immutable and hardcoded
to 126 (128 - 2) without respect to queue size. This has two negative effects:
1. when queue size is < 128, we have Virtio 1.1 specfication violation:
(2.6.5.3.1 Driver Requirements) seq_max must be <= queue_size.
This violation affects the old Linux guests (ver < 4.14). These guests
crash on these queue_size setups.
2. when queue_size > 128, as was pointed out by Denis Lunev <den@virtuozzo.com>,
seg_max restrics guest's block request length which affects guests'
performance making them issues more block request than needed.
https://lists.gnu.org/archive/html/qemu-devel/2017-12/msg03721.html
To mitigate this two effects, the patch adds the property adjusting seg_max
to queue size automaticaly. Since seg_max is a guest visible parameter,
the property is machine type managable and allows to choose between
old (seg_max = 126 always) and new (seg_max = queue_size - 2) behaviors.
Not to change the behavior of the older VMs, prevent setting the default
seg_max_adjust value for older machine types.

At the moment when the guest writes a status of 0, we only reset the
virtio core state but not the virtio-mmio state. The virtio-mmio
specification says (v1.1 cs01, 4.2.2.1 Device Requirements:
MMIO Device Register Layout):
Upon reset, the device MUST clear all bits in InterruptStatus and
ready bits in the QueueReady register for all queues in the device.
The core already takes care of InterruptStatus by clearing isr, but we
still need to clear QueueReady.
It would be tempting to clean all registers, but since the specification
doesn't say anything more, guests could rely on the registers keeping
their state across reset. Linux for example, relies on this for
GuestPageSize in the legacy MMIO tranport.

Virtqueue notifications are not necessary during polling, so we disable
them. This allows the guest driver to avoid MMIO vmexits.
Unfortunately the virtio-blk and virtio-scsi handler functions re-enable
notifications, defeating this optimization.
Fix virtio-blk and virtio-scsi emulation so they leave notifications
disabled. The key thing to remember for correctness is that polling
always checks one last time after ending its loop, therefore it's safe
to lose the race when re-enabling notifications at the end of polling.
There is a measurable performance improvement of 5-10% with the null-co
block driver. Real-life storage configurations will see a smaller
improvement because the MMIO vmexit overhead contributes less to
latency.

Currently the SLOF firmware for pseries guests will disable/re-enable
a PCI device multiple times via IO/MEM/MASTER bits of PCI_COMMAND
register after the initial probe/feature negotiation, as it tends to
work with a single device at a time at various stages like probing
and running block/network bootloaders without doing a full reset
in-between.
In QEMU, when PCI_COMMAND_MASTER is disabled we disable the
corresponding IOMMU memory region, so DMA accesses (including to vring
fields like idx/flags) will no longer undergo the necessary
translation. Normally we wouldn't expect this to happen since it would
be misbehavior on the driver side to continue driving DMA requests.
However, in the case of pseries, with iommu_platform=on, we trigger the
following sequence when tearing down the virtio-blk dataplane ioeventfd

I.e. the calling code is only scheduling a one-shot BH for
virtio_blk_data_plane_stop_bh, but somehow we end up trying to process
an additional virtqueue entry before we get there. This is likely due
to the following check in virtio_queue_host_notifier_aio_poll:
static bool virtio_queue_host_notifier_aio_poll(void *opaque)
{
EventNotifier *n = opaque;
VirtQueue *vq = container_of(n, VirtQueue, host_notifier);
bool progress;
if (!vq->vring.desc || virtio_queue_empty(vq)) {
return false;
}
progress = virtio_queue_notify_aio_vq(vq);
namely the call to virtio_queue_empty(). In this case, since no new
requests have actually been issued, shadow_avail_idx == last_avail_idx,
so we actually try to access the vring via vring_avail_idx() to get
the latest non-shadowed idx:
int virtio_queue_empty(VirtQueue *vq)
{
bool empty;
...
if (vq->shadow_avail_idx != vq->last_avail_idx) {
return 0;
}
rcu_read_lock();
empty = vring_avail_idx(vq) == vq->last_avail_idx;
rcu_read_unlock();
return empty;
but since the IOMMU region has been disabled we get a bogus value (0
usually), which causes virtio_queue_empty() to falsely report that
there are entries to be processed, which causes errors such as:
"virtio: zero sized buffers are not allowed"
or
"virtio-blk missing headers"
and puts the device in an error state.
This patch works around the issue by introducing virtio_set_disabled(),
which sets a 'disabled' flag to bypass checks like virtio_queue_empty()
when bus-mastering is disabled. Since we'd check this flag at all the
same sites as vdev->broken, we replace those checks with an inline
function which checks for either vdev->broken or vdev->disabled.
The 'disabled' flag is only migrated when set, which should be fairly
rare, but to maintain migration compatibility we disable it's use for
older machine types. Users requiring the use of the flag in conjunction
with older machine types can set it explicitly as a virtio-device
option.
NOTES:
- This leaves some other oddities in play, like the fact that
DRIVER_OK also gets unset in response to bus-mastering being
disabled, but not restored (however the device seems to continue
working)
- Similarly, we disable the host notifier via
virtio_bus_stop_ioeventfd(), which seems to move the handling out
of virtio-blk dataplane and back into the main IO thread, and it
ends up staying there till a reset (but otherwise continues working
normally)

occupies the 32-bit words 6 and 7 in the event record contiguously, with
the upper and lower unused bits clear due to alignment or maximum

When checking whether a stream ID is in range of the stream table, we
have so far been only checking it against our implementation limit
(SMMU_IDR1_SIDSIZE). However, the guest can program the
STRTAB_BASE_CFG.LOG2SIZE field to a size that is smaller than this
limit.
Check the stream ID against this limit as well to match the hardware
behavior of raising C_BAD_STREAMID events in case the limit is exceeded.
Also, ensure that we do not go one entry beyond the end of the table by
checking that its index is strictly smaller than the table size.

In the SMMU_STRTAB_BASE register, the stream table base address only
occupies bits [51:6]. Other bits, such as RA (bit [62]), must be masked
out to obtain the base address.
The branch for 2-level stream tables correctly applies this mask by way
of SMMU_BASE_ADDR_MASK, but the one for linear stream tables does not.
Apply the missing mask in that case as well so that the correct stream
base address is used by guests which configure a linear stream table.
Linux guests are unaffected by this change because they choose a 2-level
stream table layout for the QEMU SMMUv3, based on the size of its stream
ID space.

Commit aa57020774, by mistake used MachineClass::numa_mem_supported

Luckily change didn't break machines that support NUMA, as the field
is set to true for them.
But the field is not intended for checking if NUMA is supported and
will be flipped to false within this release for new machine types.
Fix it:
- by using previously used condition
!mc->cpu_index_to_instance_props || !mc->get_default_cpu_node_id
the first time and then use MachineState::numa_state down the road
to check if NUMA is supported

Rename Error ** parameter in check_only_migratable to common errp.
In device_set_realized:
- Move "if (local_err != NULL)" closer to error setters.
- Drop 'Error **local_errp': it doesn't save any LoCs, but it's very
unusual.

Mostly, Error ** is for returning error from the function, so the
callee sets it. However error_append_security_model_hint and
error_append_socket_sockfd_hint get already filled errp
parameter. They don't change the pointer itself, only change the
internal state of referenced Error object. So we can make it Error
*const * errp, to stress the behavior. It will also help coccinelle
script (in future) to distinguish such cases from common errp usage.

This reverts commit cdcca22aab.
Commit cdcca22aab is a superseded version of the next commit that
crept in by accident. Revert it, so the final version applies.

We don't need Error **, as all callers pass local Error object, which
isn't used after the call. Use Error * instead.

Local Error * variables are conventionally named @err or @local_err,
and Error ** parameters @errp. Naming local variables like parameters
is confusing. Clean that up.
Naming parameters like local variables is also confusing. Left for
another day.

memory_device_get_free_addr() dereferences @errp when
memory_device_check_addable() fails. That's wrong; see the big
comment in error.h. Introduced in commit 1b6d6af21b "pc-dimm: factor
out capacity and slot checks into MemoryDevice".
No caller actually passes null.
Fix anyway: splice in a local Error *err, and error_propagate().
