Currently qemu_mallocz calls malloc and handling of zero by malloc is
implementation defined behaviour:
http://www.opengroup.org/onlinepubs/7990989775/xsh/malloc.html
malloc(0) on AIX returns NULL[1] and qcow2 images without snapshots
are thus unusable

This patch improves G364 video card emulation (used in MIPS Magnum machine):
- Use memory dirty tracking to not refresh whole screen each time
- Use macros for debugging messages
- Add support for hardware cursor
- Handle Y-panning
- Raise irq at each screen redraw
- Support retrieving of some registers
- Add load/save support
The emulation has been tested in Linux 2.1 and Windows NT 3.5, in
640x480, 800x600, 1024x768 and 1280x1024 resolutions.

The DisplayState refactoring changed the machine init function to create a
DisplayState for each VGA device instead of being passed an existing
DisplayState. This change is critical to enable multiple graphics device
support.
Unfortunately, the serial/parallel/console code is structured today to run
before machine init to fill out the CharDriverState table which the machine
init function uses to determine whether to create the required devices.
Since a 'vc' is a type of CharDriverState, the CharDriverState code requires
that a DisplayState exist before it runs creating a circular dependency.
To fix this, this splits the creation of the initial CharDriverState from
the initialization of the text console. We can then in a second step associate
a DisplayState with all TextConsoles. This allows us to create the
CharDriverState's first, machine init, then associate the TextConsoles with
a DisplayState.
This code screams for more cleanup.

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.

This patch changes the DisplayState interface adding support for
multiple frontends at the same time (sdl and vnc) and implements most
of the benefit of the shared_buf patch without the added complexity.
Currently DisplayState is managed by sdl (or vnc) and sdl (or vnc) is
also responsible for allocating the data and setting the depth.
Vga.c (or another backend) will do any necessary conversion.
The idea is to change it so that is vga.c (or another backend) together
with console.c that fully manage the DisplayState interface allocating
data and setting the depth (either 16 or 32 bit, if the guest uses a
different resolution or is in text mode, vga.c (or another backend) is
in charge of doing the conversion seamlessly).
The other idea is that DisplayState supports *multiple* frontends
like sdl and vnc; each of them can register some callbacks to be called
when a display event occurs.
The interesting changes are:
- the new structures and related functions in console.h and console.c
in particular the following functions are very helpful to manage a
DisplaySurface:
qemu_create_displaysurface
qemu_resize_displaysurface
qemu_create_displaysurface_from
qemu_free_displaysurface
- console_select and qemu_console_resize in console.c
this two functions manage multiple consoles on a single host display
- moving code around in hw/vga.c
as for the shared_buf patch this is necessary to be able to handle a dynamic
DisplaySurface bpp
- changes to vga_draw_graphic in hw/vga.c
this is the place where the DisplaySurface buffer is shared with the
videoram, when possible;
Compared to the last version the only changes are:
- do not remove support to dpy_copy in cirrus_vga
- change the name of the displaysurface handling functions

Do not handle bgr host displays in the backends.
Right now a bgr flag exists so that sdl can set it, if the SDL_Surface
is bgr.
Afterwards the graphic device (e.g. vga.c) does the needed conversion.
With this patch series is sdl that is responsible for rendering the format
provided by the graphic device that must provide a DisplaySurface
(ds->surface) in 16 or 32 bpp, rgb.
Afterwards sdl creates a SDL_Surface from the given DisplaySurface and
blits it into the main SDL_Surface using SDL_BlitSurface.
Everything is handled by sdl transparently, because SDL_BlitSurface is
perfectly capable of handling bgr displays by itself.

The patch applies to upstream qemu as well as kvm-userspace, but since it is
the qemu configure script I think it should go to upstream qemu (Anthony)
first and with the next merge to kvm-userspace. On the other hand it is the kvm
probe so an ack from Avi in case v3 is ok would be reasonable.
*updates*
v2 - it also reports other errors than just #error preprocessor statements
(requested by Avi)
v3 - In case awk or grep is not installed it now gracfully (silently)
fails still disabling kvm (requested by Anthony)
This patch is about reporting more details of the issue if configuring kvm
fails. Therefore this patch keeps the qemu style configure output which is a
list of "$Feature $Status", but extend the "no" result like "KVM Support no"
with some more information.
There might be a lot of things going wrong with that probe and I don't want
to handle all of them, but if it is one of the known checks e.g. for
KVM_API_VERSION then we could grep/awk that out and report it. The patch
reports in case of a known case in the style
"KVM support no - (Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS)"
In case more than one #error is triggered it creates a comma separated list in
those brackets and in case it is something else than an #error it just reports
plain old "no".

If a X window is not viewable, XGrabPointer() fails and
returns GrabNotViewable. SDL's X backend currently handles
this by retrying the grab until the window becomes viewable
again.
This means e.g. if you Ctrl-Alt-RightArrow to switch
workspaces, QEMU tries to grab, SDL blocks because the
window isn't viewable and your guest stops executing until
you switch back to that workspace again.
See this Fedora bug for the gory details:
https://bugzilla.redhat.com/480065
Some SDL backends will return SDL_GRAB_OFF from
SDL_WM_GrabInput(), so the fix is to make the X backend do
this if the grab fails.
The only side-effect in QEMU is that if SDL_WM_GrabInput()
fails we still change the window title to indicate that it's
grabbed, when in fact it's not. This patch fixes that minor
issue.

After my last patch to fix interrupt coalescing was rejected
on the basis that it is too intrusive we decided to make the
fix much more localized and only fix the problem for RTC time
source. Unfortunately it is impossible to fix the problem entirely
inside RTC code like Andrzej proposed since Windows reads RTC
register C more then once on each time interrupt so it is impossible
to count reliably how many interrupt windows actually handled.
Proposed solution is localized to I386 target and is disabled by
default. To enable it "-rtc-td-hack" flag should be used.
