Markus Armbruster 166a1cf404 backends/dbus-vmstate: Fix short read error handling
When dbus_vmstate_post_load() fails, it complains to stderr.  Except
on short read, where it checks with g_return_val_if_fail().  This
fails silently if G_DISABLE_CHECKS is undefined (it should be), or
else pads the short read with uninitialized bytes.

Replace g_return_val_if_fail() by a proper error check.

On Fedora 33, gcc 10.2.1 notes that scsi_cdb_length(buf) can set
len==-1, which in turn overflows g_malloc():

In function ‘scsi_disk_new_request_dump’,

Silence it with a decent assertion, since we only convert a buffer to
bytes when we have a valid cdb length.

Andrew Jeffery c59f781e3b hw/misc: Model KCS devices in the Aspeed LPC controller
Keyboard-Controller-Style devices for IPMI purposes are exposed via LPC
IO cycles from the BMC to the host.

Expose support on the BMC side by implementing the usual MMIO
behaviours, and expose the ability to inspect the KCS registers in
"host" style by accessing QOM properties associated with each register.

The model caters to the IRQ style of both the AST2600 and the earlier
SoCs (AST2400 and AST2500). The AST2600 allocates an IRQ for each LPC
sub-device, while there is a single IRQ shared across all subdevices on
the AST2400 and AST2500.

Joel Stanley a4ea92013d arm/ast2600: Fix SMP booting with -kernel
The ast2600 machines do not have PSCI firmware, so this property should
have never been set. Removing this node fixes SMP booting Linux kernels
that have PSCI enabled, as Linux fails to find PSCI in the device tree
and falls back to the soc-specific method for enabling secondary CPUs.

The comment is out of date as Qemu has supported -kernel booting since
9bb6d14081 ("aspeed: Add boot stub for smp booting"), in v5.1.

Cleber Rosa 93fca0f241 Acceptance Tests: restore downloading of VM images
The "get-vm-images" target defined in tests/Makefile.include is a
prerequisite for "check-acceptance", so that those files get
downloaded before the Avocado job even starts.

It looks like on c401c058a1 a TARGETS variable was introduced with a
different content than it was previously coming from the main
Makefile.  From that point on, the "get-vm-images" succeed without
doing anything because there was no matching architecture to download.

This restores the download of images (that match targets to be built)
before the job starts, eliminating downloads and their associated
failures during the tests.

Minwoo Im f432fdfa12 hw/block/nvme: support changed namespace asynchronous event
If namespace inventory is changed due to some reasons (e.g., namespace
attachment/detachment), controller can send out event notifier to the
host to manage namespaces.

This patch sends out the AEN to the host after either attach or detach
namespaces from controllers.  To support clear of the event from the
controller, this patch also implemented Get Log Page command for Changed
Namespace List log type.  To return namespace id list through the
command, when namespace inventory is updated, id is added to the
per-controller list (changed_ns_list).

To indicate the support of this async event, this patch set
OAES(Optional Asynchronous Events Supported) in Identify Controller data
structure.

Minwoo Im 645ce1a70c hw/block/nvme: support namespace attachment command
This patch supports Namespace Attachment command for the pre-defined
nvme-ns device nodes.  Of course, attach/detach namespace should only be
supported in case 'subsys' is given.  This is because if we detach a
namespace from a controller, somebody needs to manage the detached, but
allocated namespace in the NVMe subsystem.

As command effect for the namespace attachment command is registered,
the host will be notified that namespace inventory is changed so that
host will rescan the namespace inventory after this command.  For
example, kernel driver manages this command effect via passthru IOCTL.

Minwoo Im 94d8d6d167 hw/block/nvme: support allocated namespace type
From NVMe spec 1.4b "6.1.5. NSID and Namespace Relationships" defines
valid namespace types:

	- Unallocated: Not exists in the NVMe subsystem
	- Allocated: Exists in the NVMe subsystem
	- Inactive: Not attached to the controller
	- Active: Attached to the controller

This patch added support for allocated, but not attached namespace type:

	!nvme_ns(n, nsid) && nvme_subsys_ns(n->subsys, nsid)

nvme_ns() returns attached namespace instance of the given controller
and nvme_subsys_ns() returns allocated namespace instance in the
subsystem.

Minwoo Im 037953b5b2 hw/block/nvme: support namespace detach
Given that now we have nvme-subsys device supported, we can manage
namespace allocated, but not attached: detached.  This patch introduced
a parameter for nvme-ns device named 'detached'.  This parameter
indicates whether the given namespace device is detached from
a entire NVMe subsystem('subsys' given case, shared namespace) or a
controller('bus' given case, private namespace).

- Allocated namespace

  1) Shared ns in the subsystem 'subsys0':

     -device nvme-ns,id=ns1,drive=blknvme0,nsid=1,subsys=subsys0,detached=true

  2) Private ns for the controller 'nvme0' of the subsystem 'subsys0':

     -device nvme-subsys,id=subsys0
     -device nvme,serial=foo,id=nvme0,subsys=subsys0
     -device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true

  3) (Invalid case) Controller 'nvme0' has no subsystem to manage ns:

     -device nvme,serial=foo,id=nvme0
     -device nvme-ns,id=ns1,drive=blknvme0,nsid=1,bus=nvme0,detached=true
