In most cases the functions passed to VMSTATE_VIRTIO_DEVICE
only call the virtio_load and virtio_save wrappers. Some include some
pre- and post- massaging too. The massaging is better expressed
as such in the VMStateDescription.
Let us prepare for changing the semantic of the VMSTATE_VIRTIO_DEVICE
macro so that it is more similar to the other VMSTATE_*_DEVICE macros
in a sense that it is a field definition.
The preprocessor conditionals are going to be removed as soon as
every usage is converted to the new semantic.

The virtio_scsi_bad_req() function is called when a guest sends a
request with missing or ill-sized headers. This generally happens
when the virtio_scsi_parse_req() function returns an error.
With this patch, virtio_scsi_bad_req() will mark the device as broken,
detach the request from the virtqueue and free it, instead of forcing
QEMU to exit.
In nearly all locations where virtio_scsi_bad_req() is called, the only
thing to do next is to return to the caller.
The virtio_scsi_handle_cmd_req_prepare() function is an exception though.
It is called in a loop by virtio_scsi_handle_cmd_vq() and passed requests
freshly popped from a cmd virtqueue; virtio_scsi_handle_cmd_req_prepare()
does some sanity checks on the request and returns a boolean flag to
indicate whether the request should be queued or not. In the latter case,
virtio_scsi_handle_cmd_req_prepare() has detected a non-fatal error and
sent a response back to the guest.
We have now a new condition to take into account: the device is broken
and should stop all processing.
The return value of virtio_scsi_handle_cmd_req_prepare() is hence changed
to an int. A return value of zero means that the request should be queued.
Other non-fatal error cases where the request shoudn't be queued return
a negative errno (values are vaguely inspired by the error condition, but
the only goal here is to discriminate the case we're interested in).
And finally, if virtio_scsi_bad_req() was called, -EINVAL is returned. In
this case, virtio_scsi_handle_cmd_vq() detaches and frees already queued
requests, instead of submitting them.

All these errors are caused by a buggy guest: QEMU should not exit.
With this patch, if virtio_blk_handle_request() detects a buggy request, it
marks the device as broken and returns an error to the caller so it takes
appropriate action.
In the case of virtio_blk_handle_vq(), we detach the request from the
virtqueue, free its allocated memory and stop popping new requests.
We don't need to bother about multireq since virtio_blk_handle_request()
errors out early and mrb.num_reqs == 0.
In the case of virtio_blk_dma_restart_bh(), we need to detach and free all
queued requests as well.

A broken guest may send a request without providing buffers for the reply
or for the request itself, and virtqueue_pop() will return an element with
either in_num == 0 or out_num == 0.
All 9P requests are expected to start with the following 7-byte header:
uint32_t size_le;
uint8_t id;
uint16_t tag_le;
If iov_to_buf() fails to return these 7 bytes, then something is wrong in
the guest.
In both cases, it is wrong to crash QEMU, since the root cause lies in the
guest.
This patch hence does the following:
- keep the check of in_num since pdu_complete() assumes it has enough
space to store the reply and we will send something broken to the guest
- let iov_to_buf() handle out_num == 0, since it will return 0 just like
if the guest had provided an zero-sized buffer.
- call virtio_error() to inform the guest that the device is now broken,
instead of aborting
- detach the request from the virtqueue and free it

Ports enter a "throttled" state when writing to the chardev would block.
The current output VirtQueueElement is kept around until the chardev

There are several places in the virtio-serial lifecycle where the
VirtQueueElement should be thrown away. For example, if the virtio
device is reset then virtqueue elements are no longer valid.
This patch adds the discard_throttle_data() function to unmap the
scatter-gather list and decrement vq->inuse. This ensures that the
VirtQueueElement is freed properly.

Extract a new function to do this.
Later patches add virtio_detach_element() calls to existing device so
that scatter-gather lists are unmapped and vq->inuse goes back to zero
during device reset. Currently some devices don't bother and simply
call g_free(elem) which is not a clean way to throw away a

for the "pseries" machine by default). Due to this reason, the
linux-user target already switched to POWER8 a while ago (see commit

Internally inside QEMU this is a device. It is a strange device that
provides no hardware interface but allows QEMU to monkey patch memory
specified when it is created. To be able to do this it has a reset
callback that does the memory operations.
This device allows the user to monkey patch memory. To be able to do
this it needs a backend to manage the datas, the same as other
