Add support for the VIRTIO_F_IN_ORDER feature across a variety of vhost
devices.
The inclusion of VIRTIO_F_IN_ORDER in the feature bits arrays for these
devices ensures that the backend is capable of offering and providing
support for this feature, and that it can be disabled if the backend
does not support it.

Add VIRTIO_F_IN_ORDER feature support for the virtqueue_flush operation.
The goal of the virtqueue_ordered_flush operation when the
VIRTIO_F_IN_ORDER feature has been negotiated is to write elements to
the used/descriptor ring in-order and then update used_idx.
The function iterates through the VirtQueueElement used_elems array
in-order starting at vq->used_idx. If the element is valid (filled), the
element is written to the used/descriptor ring. This process continues
until we find an invalid (not filled) element.
For packed VQs, the first entry (at vq->used_idx) is written to the
descriptor ring last so the guest doesn't see any invalid descriptors.
If any elements were written, the used_idx is updated.

Add VIRTIO_F_IN_ORDER feature support for the virtqueue_fill operation.
The goal of the virtqueue_ordered_fill operation when the
VIRTIO_F_IN_ORDER feature has been negotiated is to search for this
now-used element, set its length, and mark the element as filled in
the VirtQueue's used_elems array.
By marking the element as filled, it will indicate that this element has
been processed and is ready to be flushed, so long as the element is
in-order.

Add VIRTIO_F_IN_ORDER feature support in virtqueue_split_pop and
virtqueue_packed_pop.
VirtQueueElements popped from the available/descritpor ring are added to
the VirtQueue's used_elems array in-order and in the same fashion as
they would be added the used and descriptor rings, respectively.
This will allow us to keep track of the current order, what elements
have been written, as well as an element's essential data after being
processed.

Add the boolean 'in_order_filled' member to the VirtQueueElement structure.
The use of this boolean will signify whether the element has been processed
and is ready to be flushed (so long as the element is in-order). This
boolean is used to support the VIRTIO_F_IN_ORDER feature.

When setting the parameters of a PCM stream, we compute the bit flag
with the format and rate values as shift operand to check if they are
set in supported_formats and supported_rates.
If the guest provides a format/rate value which when shifting 1 results
in a value bigger than the number of bits in
supported_formats/supported_rates, we must report an error.
Previously, this ended up triggering the not reached assertions later
when converting to internal QEMU values.

When reading input audio in the virtio-snd input callback,
virtio_snd_pcm_in_cb(), we do not check whether the iov can actually fit
the data buffer. This is because we use the buffer->size field as a
total-so-far accumulator instead of byte-size-left like in TX buffers.
This triggers an out of bounds write if the size of the virtio queue
element is equal to virtio_snd_pcm_status, which makes the available
space for audio data zero. This commit adds a check for reaching the
maximum buffer size before attempting any writes.

CXL spec 3.1 section 8.2.9.9.11.2 describes the DDR5 Error Check Scrub (ECS)
control feature.
The Error Check Scrub (ECS) is a feature defined in JEDEC DDR5 SDRAM
Specification (JESD79-5) and allows the DRAM to internally read, correct
single-bit errors, and write back corrected data bits to the DRAM array
while providing transparency to error counts. The ECS control feature
allows the request to configure ECS input configurations during system
boot or at run-time.
The ECS control allows the requester to change the log entry type, the ECS
threshold count provided that the request is within the definition
specified in DDR5 mode registers, change mode between codeword mode and
row count mode, and reset the ECS counter.

feature. The device patrol scrub proactively locates and makes corrections
to errors in regular cycle. The patrol scrub control allows the request to

The patrol scrub control allows the requester to specify the number of
hours for which the patrol scrub cycles must be completed, provided that
the requested number is not less than the minimum number of hours for the
patrol scrub cycle that the device is capable of. In addition, the patrol
scrub controls allow the host to disable and enable the feature in case
disabling of the feature is needed for other purposes such as
performance-aware operations which require the background operations to be
turned off.

by adding an assert to __toggle_media(). Now, enabling when already

According to the datasheet of ASPEED SOCs,

Only AST2400 utilized a pool buffer share to all I2C bus.
And firmware required to set the offset of pool buffer
by writing "Function Control Register(I2CD 00)"
To make this model more readable, will change to introduce
a new bus pool buffer attribute in AspeedI2Cbus.
So, it does not need to calculate the pool buffer offset
for different I2C bus.
This patch rename the I2C class pool attribute to share_pool.

Coverity reports a possible integer overflow because routine
aspeeed_smc_hclk_divisor() has a codepath returning 0, which could
lead to an integer overflow when computing variable 'hclk_shift' in
the caller aspeed_smc_dma_calibration().
The value passed to aspeed_smc_hclk_divisor() is always between 0 and
15 and, in this case, there is always a matching hclk divisor. Remove
the return 0 and use g_assert_not_reached() instead.

While the `allow-rpcs` option is documented in the CLI options
section, it was missing in the section about the configuration file
syntax.
And while it's mentioned that "the list of keys follows the command line
options", having `block-rpcs` there but not `allow-rpcs` seems like
being a potential source of confusion; and as it's cheap to add let's
just do so.

It is confusing having many different pieces of code enabling and
disabling commands, and it is not clear that they all have the same
semantics, especially wrt prioritization of the block/allow lists.
The code attempted to prevent the user from setting both the block
and allow lists concurrently, however, the logic was flawed as it
checked settings in the configuration file separately from the
command line arguments. Thus it was possible to set a block list
in the config file and an allow list via a command line argument.
The --dump-conf option also creates a configuration file with both
keys present, even if unset, which means it is creating a config
that cannot actually be loaded again.
Centralizing the code in a single method "ga_apply_command_filters"
will provide a strong guarantee of consistency and clarify the
intended behaviour. With this there is no compelling technical
reason to prevent concurrent setting of both the allow and block
lists, so this flawed restriction is removed.

Allowing the user to set the QGA_CONF environment variable to change
the default configuration file path is very unusual practice, made
more obscure since this ability is not documented.
This introduces the more normal '-c PATH' / '--config=PATH' command
line argument approach. This requires that we parse the comamnd line
twice, since we want the command line arguments to take priority over
the configuration file settings in general.

The fsfreeze commands are already written to report an error if
vss_init() fails. Reporting a more specific error message is more
helpful than a generic "command is disabled" message, which cannot
between an admin config decision and lack of platform support.

Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on other UNIX.
The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from
{"class": "CommandNotFound", "desc": "Command FOO has been disabled"}
to
{"class": "CommandNotFound", "desc": "The command FOO has not been found"}
This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.
