15138b5e6f virtio-vga: fix virtio-vga bar ordering
With virtio-vga, pci bar are reordered. Bar #2 is used for compatibility
with stdvga. By default, bar #2 is used by virtio modern io bar.
This bar is the last one introduce in the virtio pci bar layout and it's
crushed by the virtio-vga reordering. So virtio-vga and
modern-pio-notify are incompatible because virtio-vga failed to
initialize with this option.

This fix sets the modern io bar to the bar #5 to avoid conflict.

ee29f6e92d bochs-display: Fix vgamem=SIZE error handling
bochs_display_realize() rejects out-of-range vgamem.  The error
handling is broken:

    $ qemu-system-x86_64 -S -display none -monitor stdio
    QEMU 4.2.93 monitor - type 'help' for more information
    (qemu) device_add bochs-display,vgamem=1

    RAMBlock "0000:00:04.0/bochs-display-vram" already registered, abort!
    Aborted (core dumped)

Cause: bochs_display_realize() neglects to bail out after setting the
error.  Fix that.

f872c76296 stdvga+bochs-display: add dummy mmio handler
The bochs-display mmio bar has some sub-regions with the actual hardware
registers.  What happens when the guest access something outside those
regions depends on the archirecture.  On x86 those reads succeed (and
return 0xff I think).  On risc-v qemu aborts.

This patch adds handlers for the parent region, to make the wanted
behavior explicit and to make things consistent across architectures.

v2:
 - use existing unassigned_io_ops.
 - also cover stdvga.

44b5c1ebfa qxl: map rom r/o
Map qxl rom read-only into the guest, so the guest can't tamper with the
content.  qxl has a shadow copy of the rom to deal with that, but the
shadow doesn't cover the mode list.  A privilidged user in the guest can
manipulate the mode list and that to trick qemu into oob reads, leading
to a DoS via segfault if that read access happens to hit unmapped memory.

ed71c09ffd qxl: introduce hardware revision 5
The only difference to hardware revision 4 is that the device doesn't
switch to VGA mode in case someone happens to touch a VGA register,
which should make things more robust in configurations with multiple
vga devices.

Swtiching back to VGA mode happens on reset, either full machine
reset or qxl device reset (QXL_IO_RESET ioport command).

little endian variants like qemu-system-sh4 and qemu-system-sh4eb,
so that we do not have to compile the code multiple times anymore.

1df2c9a26f migration: Define VMSTATE_INSTANCE_ID_ANY
Define the new macro VMSTATE_INSTANCE_ID_ANY for callers who wants to
auto-generate the vmstate instance ID.  Previously it was hard coded
as -1 instead of this macro.  It helps to change this default value in
the follow up patches.  No functional change.

7aca3782d9 hw/display/sm501: Always map the UART0
The SM501 is a Mobile Multimedia Companion Chip with 2 UARTs.
This model only implements the first UART. Being part of the
chipset, the UART block is always mapped in memory, regardless
of whether we provide a chardev backend.

Since commit 12051d82f, qemu_chr_fe_init() accepts a NULL chardev.
Let's remove the chardev check and always map the UART in the
chipset memory.

 They introduce some internal API changes, and fix

e2328a11bd vga: cleanup mapping of VRAM for non-PCI VGA
vga_init_vbe is now used only from ISA VGA cards.  Since the alias is
not needed anymore, remove it (effectively reverting commit 8294a64d7f,
"vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29)
and the now unused vbe_mapped field of VGACommonState.  The function now
consists of a single memory_region_add_subregion call, so we can inline
it; this avoids incorrect usage from PCI cards.

e3355a0ca2 m68k: Add NeXTcube framebuffer device emulation
The NeXTcube uses a linear framebuffer with 4 greyscale colors and
a fixed resolution of 1120 * 832.
This code has been taken from Bryce Lanham's GSoC 2011 NeXT branch at

 https://github.com/blanham/qemu-NeXT/blob/next-cube/hw/next-fb.c

and altered to fit the latest interface of the current QEMU (e.g.
the device has been "qdev"-ified etc.).

b7105d280c ati-vga: Implement dummy VBlank IRQ
The MacOS driver exits if the card does not have an interrupt. If we
set PCI_INTERRUPT_PIN to 1 then it enables VBlank interrupts and it
boots but the mouse pointer cannot be moved. This patch implements a
dummy VBlank interrupt triggered by a 60 Hz timer. With this the
pointer now moves but MacOS still hangs somewhere before completely
finishing boot.

8a9224a250 hw/display: Compile various display devices as common object
Various display devices are not target-specific and can
be compiled once for all the targets.
After this commit, the 'make world' target is reduced by

ea2b7c9faa hw/display/sm501: Remove unused include
The "cpu.h" include makes devices target-specific. Since it
is not used, remove it, so the device become generic (we can
now compile it once for all targets).

8bb9a2b26d ati-vga: Add limited support for big endian frame buffer aperture
Set frame buffer endianness according to requested endianness for
frame buffer apertures. We set frame buffer to big endian if any of
the two apertures are set to big endian. Using different endianness
for the two apertures is not implemented. This fixes inverted colors
with MacOS and Xorg frame buffer driver but some Linux drivers may
have endianness issues even on real hardware so this may not fix all
cases. MorphOS uses aper0 in LE, Linux uses aper0 in BE and MacOS uses
aper1 in BE but not sure about others or if MacOS also may need aper0
in which case we'll need a more complex fix but MacOS has other
problems yet so for now this might work.
