hw/arm/exynos4210: Zero memory allocated for Exynos4210State
In exynos4210_init() we allocate memory for an Exynos4210State
struct. Generally devices can assume that the memory allocated
for their state struct is zero-initialized; we broke that
assumption here by using g_new(). Use g_new0() instead.
(In particular, some code assumes that the various irq arrays
in the Exynos4210Irq sub-struct are zero-initialized.)
In the longer term, this code should be QOMified, and then
the struct memory will be allocated elsewhere and by functions
which always zero-initalize it; but for 3.1 this is a
simple fix.

In handle_vec_simd_shli() we have a check:

So the clz32() return must be in {28,29,30,31} and the resulting

This unnecessary code confuses Coverity's analysis:

include: Add a comment to explain the origin of sizes' lookup table
The lookup table for power-of-two sizes was added in commit 540b8492618eb
for the purpose of having convenient shortcuts for these sizes in cases
when the literal number has to be present at compile time, and
expressions as '(1 * KiB)' can not be used. One such case is the
stringification of sizes. Beyond that, it is convenient to use these
shortcuts for all power-of-two sizes, even if they don't have to be
literal numbers.
Despite its convenience, this table introduced 55 lines of "dumb" code,
the purpose and origin of which are obscure without reading the message
of the commit which introduced it. This patch fixes that by adding a
comment to the code itself with a brief explanation for the reasoning
behind this table. This comment includes the short AWK script that
generated the table, so that anyone who's interested could make sure
that the values in it are correct (otherwise these values look as if
they were typed manually).

option: Make option help nicer to read
This adds some whitespace into the option help (including indentation)
and puts angle brackets around the type names. Furthermore, the list
name is no longer printed as part of every line, but only once in
advance, and only if the caller did not print a caption already.
This patch also restores the description alignment we had before commit 9cbef9d68ee1d8d0, just at 24 instead of 16 characters like we used to.
This increase is because now we have the type and two spaces of
indentation before the description, and with a usual type name length of
three chracters, this sums up to eight additional characters -- which
means that we now need 24 characters to get the same amount of padding
for most options. Also, 24 is a third of 80, which makes it kind of a
round number in terminal terms.
Finally, this patch amends the reference output of iotest 082 to match
the changes (and thus makes it pass again).

block: Add auto-read-only option
If a management application builds the block graph node by node, the
protocol layer doesn't inherit its read-only option from the format
layer any more, so it must be set explicitly.
Backing files should work on read-only storage, but at the same time, a
block job like commit should be able to reopen them read-write if they
are on read-write storage. However, without option inheritance, reopen
only changes the read-only option for the root node (typically the
format layer), but not the protocol layer, so reopening fails (the
format layer wants to get write permissions, but the protocol layer is
still read-only).
A simple workaround for the problem in the management tool would be to
open the protocol layer always read-write and to make only the format
layer read-only for backing files. However, sometimes the file is
actually stored on read-only storage and we don't know whether the image
can be opened read-write (for example, for NBD it depends on the server
we're trying to connect to). This adds an option that makes QEMU try to
open the image read-write, but allows it to degrade to a read-only mode
without returning an error.
The documentation for this option is consciously phrased in a way that
allows QEMU to switch to a better model eventually: Instead of trying
when the image is first opened, making the read-only flag dynamic and
changing it automatically whenever the first BLK_PERM_WRITE user is
attached or the last one is detached would be much more useful
behaviour.
Unfortunately, this more useful behaviour is also a lot harder to
implement, and libvirt needs a solution now before it can switch to
-blockdev, so let's start with this easier approach for now.
Instead of adding a new auto-read-only option, turning the existing
read-only into an enum (with a bool alternate for compatibility) was
considered, but it complicated the implementation to the point that it
didn't seem to be worth it.

This board is based on the Xilinx Versal SoC. The exact
details of what peripherals are attached to this board
will remain in control of QEMU. QEMU will generate an
FDT on the fly for Linux and other software to auto-discover
peripherals.

Coldfire defines an "Unsupported instruction" exception if execution

We use it with instructions that are in fact undefined or illegal,

Currently whenever the qemu-ga's service doesn't find the virtio-serial
the run_agent() loops in a QGA_RETRY_INTERVAL (default 5 seconds)
intervals and try to restart the qemu-ga which causes a synchronous loop.
Changed to wait and listen for the serial events by registering for
notifications a proper serial event handler that deals with events:
DBT_DEVICEARRIVAL indicates that the device has been inserted and
is available
DBT_DEVICEREMOVECOMPLETE indicates that the devive has been removed
Which allow us to determine when the channel path is available for the
qemu-ga to restart.

qga-win: install service with --retry-path set by default
It's nicer from a management perspective that the agent can survive
hotplug/unplug of the channel device, or be started prior to the
installation of the channel device's driver without and still be able
to resume normal function afterward. On linux there are alternatives
like systemd to support this, but on w32 --retry-path is the only
option so it makes sense to set it by default when installed as a
w32 service.

qga: add --retry-path option for re-initializing channel on failure
This adds an option to instruct the agent to periodically attempt
re-opening the communication channel after a channel error has
occurred. The main use-case for this is providing an OS-independent
way of allowing the agent to survive situations like hotplug/unplug of
the communication channel, or initial guest set up where the agent may
be installed/started prior to the installation of the channel device's
driver.
There are nicer ways of implementing this functionality via things
like systemd services, but this option is useful for platforms like
*BSD/w32.
Currently a channel error will result in the GSource for that channel
being removed from the GMainLoop, but the main loop continuing to run.
That behavior results in a dead loop when --retry-path isn't set, and
prevents us from knowing when to attempt re-opening the channel when
it is set, so we also force the loop to exit as part of this patch.

qga: hang GAConfig/socket_activation off of GAState global
For w32 services we rely on the global GAState to access resources
associated with the agent within service_main(). Currently this is
sufficient for starting the agent since we open the channel once prior
to calling service_main(), and simply start the GMainLoop to start the
agent from within service_main().
Eventually we want to be able to also [re-]open the communication
channel from within service_main(), which requires access to
config/socket_activation variables, so we hang them off GAState in
preparation for that.

qga: group agent init/cleanup init separate routines
This patch better separates the init/cleanup routines out into
separate functions to make the start-up procedure a bit easier to
follow. This will be useful when we eventually break out the actual
start/stop of the agent's main loop into separates routines that
can be called multiple times after the init phase.

Probe the volume for disk extents and return list of all disks.
Originally only first disk of composite volume was returned.
Note that the patch changes get_pci_info() from one state of brokenness
into a different state of brokenness. In other words it still does not do
what it's supposed to do (see comment in code). If anyone knows how to
fix it, please step in.

build: rename CONFIG_QGA_NTDDDISK to CONFIG_QGA_NTDDSCSI
There was inconsistency between commits:
50cbebb9a3 configure: add configure check for ntdddisk.h a3ef3b2272 qga: added bus type and disk location path
The first commit added #define CONFIG_QGA_NTDDDISK but the second commit
expected the name to be CONFIG_QGA_NTDDSCSI. As a result the code in
second patch was never used.
Renaming the option to CONFIG_QGA_NTDDSCSI to match the name of header
file that is being checked for.
