Peter Xu 3ab72385b2 qapi: Drop qapi_event_send_FOO()'s Error ** argument
The generated qapi_event_send_FOO() take an Error ** argument.  They
can't actually fail, because all they do with the argument is passing it
to functions that can't fail: the QObject output visitor, and the
@qmp_emit callback, which is either monitor_qapi_event_queue() or
event_test_emit().

Drop the argument, and pass &error_abort to the QObject output visitor
and @qmp_emit instead.

Thomas Huth 2d6ff33a03 hw/s390x/virtio-ccw: Consolidate calls to virtio_ccw_unrealize()
Currently, every virtio-ccw device explicitely sets its unrealize
function to virtio_ccw_unrealize() in its class_init function.
We can simplify this by using a common unrealize function, just like
it is already done for the realize functions.

Fix MPS2 SCC config register values for the mps2-an511

Peter Maydell f8add62c0c hw/display/bcm2835_fb: Validate config settings
Validate the config settings that the guest tries to set.

The wiki page documentation is not really accurate here:
generally rather than failing requests to set bad parameters,
the hardware will just clip them to something sensible.

Validate the most important parameters: sizes and
the viewport offsets. This prevents the framebuffer
code from trying to read out-of-range memory.

In the property handling code, we validate the new parameters every
time we encounter a tag that sets them. This means we validate the
config multiple times if the request includes multiple config-setting
tags, but the code would require significant restructuring to do a
validation only once but still return the clipped settings for
get-parameter tags and the buffer allocation tag.

Validation of settings made via the older bcm2835_fb_mbox_push()
function will be done in the next commit.

Peter Maydell 01f18af98b hw/display/bcm2835_fb: Fix handling of virtual framebuffer
The raspi framebuffir in bcm2835_fb supports the definition
of a virtual "viewport", which is smaller than the full
physical framebuffer size and at an adjustable offset within
it. Only the viewport area is sent to the screen. This allows
the guest to do things like double buffering, or scrolling
by adjusting the viewport origin. Currently QEMU doesn't
implement this at all.

Add support for this feature:
 * the property mailbox code needs to distinguish the
   virtual width/height from the physical width/height
 * the framebuffer code needs to do something with the
   virtual width/height/origin information

Note that the wiki documentation on the semantics of the
virtual and physical height and width has it the wrong way
around -- the virtual size is the size of the allocated
buffer, and the physical size is the size of the display,
so the virtual size is always the same as or larger than
the physical.

If the viewport size is set smaller than the physical
screen size, we ignore the viewport settings completely
and just display the physical screen area.

Peter Maydell a02755ece0 hw/misc/bcm2835_fb: Move config fields to their own struct
The handling of framebuffer properties in the bcm2835_property code
is a bit clumsy, because for each of the many fb related properties
we try to track the value we're about to set and whether we're going
to be setting a value, and then we hand all the new values off
to the framebuffer via a function which takes them all as separate
arguments. It would be simpler if the property code could easily
copy all the framebuffer's current settings, update them with
the new specified values and then ask the framebuffer to switch
to the new set.

As the first part of this refactoring, pull all the fb config
settings fields in BCM2835FBState out into their own struct.
