hw/isa/piix4: Migrate Reset Control Register
When adding the Reset register in commit
5790b757cfb we
forgot to migrate it.
While it is possible a VM using the PIIX4 is migrated just
after requesting a system shutdown, it is very unlikely.
However when restoring a migrated VM, we might have the
RCR bit #4 set on the stack and when the VM resume it
directly shutdowns.
Add a post_load() migration handler and set the default
RCR value to 0 for earlier versions, assuming the VM was
not going to shutdown before migration.

hw/arm/smmuv3: Emulate CFGI_STE_RANGE for an aligned range of StreamIDs
In emulation of the CFGI_STE_RANGE command, we now take StreamID as the

whilst the spec clearly states that
- "Invalidation is performed for an *aligned* range of 2^(Range+1)
StreamIDs."
- "The bottom Range+1 bits of the StreamID parameter are IGNORED,
aligning the range to its size."
Take CFGI_ALL (where Range == 31) as an example, if there are some random
bits in the StreamID field, we'll fail to perform the full invalidation but
get a strange range (e.g., SMMUSIDRange={.start=1, .end=0}) instead. Rework
the emulation a bit to get rid of the discrepancy with the spec.

hw/block/nvme: drain namespaces on sq deletion
For most commands, when issuing an AIO, the BlockAIOCB is stored in the
NvmeRequest aiocb pointer when the AIO is issued. The main use of this
is cancelling AIOs when deleting submission queues (it is currently not
used for Abort).
However, some commands like Dataset Management Zone Management Send
(zone reset) may involve more than one AIO and here the AIOs are issued
without saving a reference to the BlockAIOCB. This is a problem since
nvme_del_sq() will attempt to cancel outstanding AIOs, potentially with
an invalid BlockAIOCB since the aiocb pointer is not NULL'ed when the
request structure is recycled.
Fix this by
1. making sure the aiocb pointer is NULL'ed when requests are recycled
2. only attempt to cancel the AIO if the aiocb is non-NULL
3. if any AIOs could not be cancelled, drain all aio as a last resort.

cpu/core: Fix "help" of CPU core device types
Calling qdev_get_machine() from a QOM instance_init function is
fragile because we can't be sure the machine object actually
exists. And this happens to break when passing ",help" on the
command line to get the list of properties for a CPU core
device types :
$ ./qemu-system-ppc64 -device power8_v2.0-spapr-cpu-core,help
qemu-system-ppc64: ../../hw/core/machine.c:1290:
qdev_get_machine: Assertion `machine != NULL' failed.
Aborted (core dumped)
This used to work before QEMU 5.0, but commit
3df261b6676b
unwillingly introduced a subtle regression : the above command
line needs to create an instance but the instance_init function
of the base class calls qdev_get_machine() before
qemu_create_machine() has been called, which is a programming bug.
Use current_machine instead. It is okay to skip the setting of
nr_thread in this case since only its type is displayed.

hw/block/nvme: fix handling of private namespaces
Prior to this patch, if a private nvme-ns device (that is, a namespace
that is not linked to a subsystem) is wired up to an nvme-subsys linked
nvme controller device, the device fails to verify that the namespace id
is unique within the subsystem. NVM Express v1.4b, Section 6.1.6 ("NSID
and Namespace Usage") states that because the device supports Namespace
Management, "NSIDs *shall* be unique within the NVM subsystem".
Additionally, prior to this patch, private namespaces are not known to
the subsystem and the namespace is considered exclusive to the
controller with which it is initially wired up to. However, this is not
the definition of a private namespace; per Section 1.6.33 ("private
namespace"), a private namespace is just a namespace that does not
support multipath I/O or namespace sharing, which means "that it is only
able to be attached to one controller at a time".
Fix this by always allocating namespaces in the subsystem (if one is
linked to the controller), regardless of the shared/private status of
the namespace. Whether or not the namespace is shareable is controlled
by a new `shared` nvme-ns parameter.
Finally, this fix allows the nvme-ns `subsys` parameter to be removed,
since the `shared` parameter now serves the purpose of attaching the
namespace to all controllers in the subsystem upon device realization.
It is invalid to have an nvme-ns namespace device with a linked
subsystem without the parent nvme controller device also being linked to
one and since the nvme-ns devices will unconditionally be "attached" (in
QEMU terms that is) to an nvme controller device through an NvmeBus, the
nvme-ns namespace device can always get a reference to the subsystem of
the controller it is explicitly (using 'bus=' parameter) or implicitly
attaching to.

The e500plat machine device plug callback currently calls
platform_bus_link_device() for any sysbus device. This is overly
broad, because platform_bus_link_device() will unconditionally grab
the IRQs and MMIOs of the device it is passed, whether it was
intended for the platform bus or not. Restrict hotpluggability of
sysbus devices to only those devices on the dynamic sysbus allowlist.
We were mostly getting away with this because the board creates the
platform bus as the last device it creates, and so the hotplug
callback did not do anything for all the sysbus devices created by
the board itself. However if the user plugged in a device which
itself uses a sysbus device internally we would have mishandled this
and probably asserted. An example of this is:
qemu-system-ppc64 -M ppce500 -device macio-oldworld
This isn't a sensible command because the macio-oldworld device
is really specific to the 'g3beige' machine, but we now fail

After introducing non-scalar machine properties, it would be preferrable

Do not saddle ourselves with legacy oem-id and oem-table-id

acpi/piix4: reinitialize acpi PM device on reset
Commit
6be8cf56bc8b made sure that SCI is enabled in PM1.CNT
on reset in acpi_only mode by modifying acpi_pm1_cnt_reset() and
that worked for q35 as expected.
The function was introduced by commit
eaba51c573a (acpi, acpi_piix, vt82c686: factor out PM1_CNT logic)
that forgot to actually call it at piix4 reset time and as result
SCI_EN wasn't set as was expected by
6be8cf56bc8b in acpi_only mode.
So Windows crashes when it notices that SCI_EN is not set and FADT is
not providing information about how to enable it anymore.
Reproducer:
qemu-system-x86_64 -enable-kvm -M pc-i440fx-6.0,smm=off -cdrom any_windows_10x64.iso
Fix it by calling acpi_pm1_cnt_reset() at piix4 reset time.
Occasionally this patch adds reset acpi PM related registers on
piix4 reset time and de-assert sci.
piix4_pm_realize() initializes acpi pm tmr, evt, cnt and gpe.
Reset them on device reset. pm_reset() in ich9.c correctly calls
corresponding reset functions.

vhost-user-blk: add immediate cleanup on shutdown
Qemu crashes on shutdown if the chardev used by vhost-user-blk has been
finalized before the vhost-user-blk.
This happens with char-socket chardev operating in the listening mode (server).
The char-socket chardev emits "close" event at the end of finalizing when
its internal data is destroyed. This calls vhost-user-blk event handler
which in turn tries to manipulate with destroyed chardev by setting an empty
event handler for vhost-user-blk cleanup postponing.
This patch separates the shutdown case from the cleanup postponing removing
the need to set an event handler.

vhost-user-blk: perform immediate cleanup if disconnect on initialization
Commit
4bcad76f4c39 ("vhost-user-blk: delay vhost_user_blk_disconnect")
introduced postponing vhost_dev cleanup aiming to eliminate qemu aborts
because of connection problems with vhost-blk daemon.
However, it introdues a new problem. Now, any communication errors
during execution of vhost_dev_init() called by vhost_user_blk_device_realize()
lead to qemu abort on assert in vhost_dev_get_config().
This happens because vhost_user_blk_disconnect() is postponed but
it should have dropped s->connected flag by the time
vhost_user_blk_device_realize() performs a new connection opening.
On the connection opening, vhost_dev initialization in
vhost_user_blk_connect() relies on s->connection flag and
if it's not dropped, it skips vhost_dev initialization and returns
with success. Then, vhost_user_blk_device_realize()'s execution flow
goes to vhost_dev_get_config() where it's aborted on the assert.
To fix the problem this patch adds immediate cleanup on device
initialization(in vhost_user_blk_device_realize()) using different
event handlers for initialization and operation introduced in the
previous patch.
On initialization (in vhost_user_blk_device_realize()) we fully
control the initialization process. At that point, nobody can use the
device since it isn't initialized and we don't need to postpone any
cleanups, so we can do cleaup right away when there is a communication
problem with the vhost-blk daemon.
On operation we leave it as is, since the disconnect may happen when
the device is in use, so the device users may want to use vhost_dev's data
to do rollback before vhost_dev is re-initialized (e.g. in vhost_dev_set_log()).

It is useful to use different connect/disconnect event handlers

commit fixing a bug on device initialization.
This patch refactors the code to make use of them: we don't rely any
more on the VM state for choosing how to cleanup the device, instead
we explicitly use the proper event handler depending on whether
the device has been initialized.
