This patch enables dirty log tracking whenever it's needed and disables it
when it is not.
We unconditionally enable dirty log tracking on reset, restart dirty log
tracking when PCI IO regions are remapped, and disable/enable it based on
commands from the guest.

VMware VGA requires that the depth presented to the guest is the same as the
DisplaySurface that it renders to. This is because it performs a very simple
memcpy() to blit from one surface to another.
We currently hardcode a 24-bit depth. The surface allocator for SDL may, and
usually will, allocate a surface with a different depth causing screen
corruption.
This changes the code to allocate the DisplaySurface before initializing the
device which allows the depth of the DisplaySurface to be used instead of
hardcoding something.

Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them. Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.
This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.
Cirrus does not enable VBE so it would not be a problem when using Cirrus.

Device names with whitespace require quoting in the shell and in the

more convenient alias, some don't.
The place for verbose device names is DeviceInfo member desc. The

Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device init
callbacks can't signal failure because the init() callback has no
return value. This patch fixes it.
We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault. This patch fixes it.
With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

Hello,
for what I can tell, there is no way for vmware_vga to work correctly
right now. It assumes that the framebuffer bits-per-pixel and the one
from the DisplaySurface are identical (it uses directly the VRAM from
vga.c), but it always assumes 3 bytes per pixel, which is never possible
with the current version of DisplaySurface.
Attached patch fixes that by using ds_get_bits_per_pixel.
use NULL instead of 0 for pci_register_device() argument
for consistency. Any other caller uses NULL.

All VGA devices share a common field subset; currently they do so by
a macro which defines the common fields inline their state structures,
relying on the the common state being placed at offset 0 in the structure.
This makes refactoring the code difficult and requires a lot of error prone
casts.
Replace the macro by a new VGACommonState structure, and the casts by
regular field access and container_of() for upcasts.

Patch 5/7
This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.
This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.
This patch does *not* include any required changes to any device, these
changes come with the following patches.
Patch 6/7
This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;
In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.
Patch 7/7
This patch updates the graphic device code to use the new
graphical_console_init function.
As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.
