In linux kernel v2.6.33, sm501 frame buffer driver modified to support
2D graphics engine on sm501 chip. One example is "fill rectangle" operation.
But current qemu's sm501 emulation doesn't support it. This results in
graphics console disturbance.
This patch introduces sm501 2D graphics engine emulation and solve this problem.
Add SM501 2D hardware engine support.
- Add 2D engine register set read/write handlers.
- Support 'fill rectangle'. Other operations are left for future work.
- Update SM501 support status comment.

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.
Use cpu_abort() when in CPU context, abort() otherwise.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

It makes usb keyboard available for sh4/r2d system emulation.
The changes for "hw/usb-ohci.c" are as follows.
- 'localmem_base' is introduced as OHCIState struct member.
SM501 has a local memory, and it is used to pass and receive data with
OHCI driver. OHCI driver accesses it with SH4 physical memory address,
and SM501 accesses it with SM501 local address. 'localmem_base' holds
where the SM501 local memory is mapped into SH4 physical address space.
- Memory access functions modified to adjust address with 'localmem_base'.
The functions are, ohci_read_*(), ohci_put_*(), and ohci_copy_*().
- ohci_read_hcca() and ohci_put_hcca() are introduced for more consistent
implementation.
For other source files, it does,
- introduces usb_ohci_init_sm501().
- adds irq argument for SM501 initialization, to emulate USB interrupts.

Hi all,
this patch adds a DisplayAllocator interface that allows display
frontends (sdl in particular) to provide a preallocated display buffer
for the graphical backend to use.
Whenever a graphical backend cannot use
qemu_create_displaysurface_from because its own internal pixel format
cannot be exported directly (text mode or graphical mode with color
depth 8 or 24), it creates another display buffer in memory using
qemu_create_displaysurface and does the conversion.
This new buffer needs to be blitted into the sdl surface buffer every time
we need to update portions of the screen.
We can avoid this using the DisplayAllocator interace: sdl provides its
own implementation of qemu_create_displaysurface, giving back the sdl
surface buffer directly (as we used to do before the DisplayState
changes).
Since the buffer returned by sdl could be in bgr format we need to put
back in the handlers of that case.
This approach is good if the two following conditions are true:
1) the sdl surface is a software surface that resides in main memory;
2) the host display color depth is either 16 or 32 bpp.
If first condition is false we can have bad performances using sdl
and vnc together.
If the second condition is false performances are certainly not going to
improve but they shouldn't get worse either.
The first condition is always true, at least on linux/X11 systems; but I
believe is true also on other platforms.
The second condition is true in the vast majority of the cases.
This patch should also have the good side effect of solving the sdl
2D slowness malc was reporting on MacOS, because SDL_BlitSurface is not
going to be called anymore when the guest is in text mode or 24bpp.
However the root problem is still present so I suspect we may
still see some slowness on MacOS when the guest is in 32 or 16 bpp.

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.

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.
