This patch fix the behaviour and positioning of the X11 mouse cursor in HP-UX.
The current code missed to subtract the offset of the CURSOR_CTRL register from
the current mouse cursor position. The HP-UX graphics driver stores in this
register the offset of the mouse graphics compared to the current cursor
position. Without this adjustment the mouse behaves strange at the screen
borders.
Additionally, depending on the HP-UX version, the mouse cursor position
in the cursor_pos register reports different values. To accommodate this
track the current min and max reported values and auto-adjust at runtime.
With this fix the mouse now behaves as expected on HP-UX 10 and 11.

When writing this code it was assumed that register 0x118000 is the
buffer access mode for color map accesses. It turned out that this
is wrong. Instead register 0x118000 sets both src and dst buffer
access mode at the same time.
This required a larger rewrite of the code. The good thing is that
both the linear framebuffer and the register based vram access can
now be combined into one function.
This makes the linux 'stifb' framebuffer work, and both HP-UX 10.20
and HP-UX 11.11 are still working.

The migration code will not look at a VMStateDescription's
minimum_version_id_old field unless that VMSD has set the
load_state_old field to something non-NULL. (The purpose of
minimum_version_id_old is to specify what migration version is needed
for the code in the function pointed to by load_state_old to be able
to handle it on incoming migration.)
We have exactly one VMSD which still has a load_state_old,
in the PPC CPU; every other VMSD which sets minimum_version_id_old
is doing so unnecessarily. Delete all the unnecessary ones.

Previously, the large modes (>1080p) that were generated by Qemu in its EDID
were all 50 Hz. If we provide them to a Guest OS and the user selects
one of these modes, then the OS by default only gets 50 FPS. This is
especially true for Windows OS. With this patch, we are now exposing a
3840x2160@60 Hz which will allow the guest OS to get 60 FPS.

Currently QEMU defaults to a resolution of 1024x768 when exposing EDID
info to the guest OS. The EDID default info is important as this will
influence what resolution many guest OS will configure the screen with
on boot. It can also potentially influence what resolution the firmware
will configure the screen with, though until very recently EDK2 would
not handle EDID info.
One important thing to bear in mind is that the default graphics card
driver provided by Windows will leave the display set to whatever
resolution was enabled by the firmware on boot. Even if sufficient
VRAM is available, the resolution can't be changed without installing
new drivers. IOW, the default resolution choice is quite important
for usability of Windows.
Modern real world monitor hardware for desktop/laptop has supported
resolutions higher than 1024x768 for a long time now, perhaps as long
as 15+ years. There are quite a wide variety of native resolutions in
use today, however, and in wide screen form factors the height may not
be all that tall.
None the less, it is considered that there is scope for making the
QEMU default resolution slightly larger.
In considering what possible new default could be suitable, choices
considered were 1280x720 (720p), 1280x800 (WXGA) and 1280x1024 (SXGA).
In many ways, vertical space is the most important, and so 720p was
discarded due to loosing vertical space, despite being 25% wider.
The SXGA resolution would be good, but when taking into account
window titlebars/toolbars and window manager desktop UI, this might
be a little too tall for some users to fit the guest on their physical
montior.
This patch thus suggests a modest change to 1280x800 (WXGA). This
only consumes 1 MB per colour channel, allowing double buffered
framebuffer in 8 MB of VRAM. Width wise this is 25% larger than
QEMU's current default, but height wise this only adds 5%, so the
difference isn't massive on the QEMU side.
Overall there doesn't appear to be a compelling reason to stick
with 1024x768 resolution.

The monitor modes table is found by experimenting with the Monitors Control
Panel in MacOS and analysing the reads/writes. From this it can be found that
the mode is controlled by writes to the DAFB_MODE_CTRL1 and DAFB_MODE_CTRL2
registers.
Implement the first block of DAFB registers as a register array including the
existing sense register, the newly discovered control registers above, and also
the DAFB_MODE_VADDR1 and DAFB_MODE_VADDR2 registers which are used by NetBSD to
determine the current video mode.
These experiments also show that the offset of the start of video RAM and the
stride can change depending upon the monitor mode, so update macfb_draw_graphic()
and both the BI_MAC_VADDR and BI_MAC_VROW bootinfo for the q800 machine
accordingly.
Finally update macfb_common_realize() so that only the resolution and depth
supported by the display type can be specified on the command line, and add an

xlnx_dp_read allows an out-of-bounds read at its default branch because
of an improper index.
According to
https://www.xilinx.com/html_docs/registers/ug1087/ug1087-zynq-ultrascale-registers.html
(DP Module), registers 0x3A4/0x3A4/0x3AC are allowed.
DP_INT_MASK 0x000003A4 32 mixed 0xFFFFF03F Interrupt Mask Register for intrN.
DP_INT_EN 0x000003A8 32 mixed 0x00000000 Interrupt Enable Register.
DP_INT_DS 0x000003AC 32 mixed 0x00000000 Interrupt Disable Register.
In xlnx_dp_write, when the offset is 0x3A8 and 0x3AC, the virtual device
will write s->core_registers[0x3A4
>> 2]. That is to say, the maxize of s->core_registers could be ((0x3A4
>> 2) + 1). However, the current size of s->core_registers is (0x3AF >>
>> 2), that is ((0x3A4 >> 2) + 2), which is out of the range.
In xlxn_dp_read, the access to offset 0x3A8 or 0x3AC will be directed to
the offset 0x3A8 (incorrect functionality) or 0x3AC (out-of-bounds read)
rather than 0x3A4.
This patch enforces the read access to offset 0x3A8 and 0x3AC to 0x3A4,
but does not adjust the size of s->core_registers to avoid breaking
migration.

If users try to add an isa-vga device that was already registered,
still in command line, qemu will crash:
$ qemu-system-mips64el -M pica61 -device isa-vga
RAMBlock "vga.vram" already registered, abort!
Aborted (core dumped)
That particular board registers the device automaticaly, so it's
not obvious that a VGA device already exists. This patch changes
this behavior by displaying a message and exiting without crashing.

When using qemu configured with --enabled-modules, the
generic stubs are used instead of the module symbols:
qemu-system-x86_64: -device virtio-vga,blob=on: cannot enable blob resources without udmabuf
Restrict the stubs to Linux and only link them when
CONFIG_VIRTIO_GPU is disabled (only the modularized
version is available when it is enabled).

Before commit 49afbca3b0 ("virtio-gpu: drop
use_virgl_renderer"), use_virgl_renderer was preventing calling GL
functions from non-GL context threads. The innocuously looking
g->parent_obj.use_virgl_renderer = false;
was set the first time virtio_gpu_gl_reset() was called, during
pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset()
calls in IO threads, without associated GL context, were thus skipping
GL calls and avoided warnings or crashes (see also
https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

Since the migration stream is already broken, we can use this opportunity to

than as an array of bytes.

meaningless error message, add an Error parameter to allow reporting the

be distinguished in the caller.

The highest VBE_DISPI_INDEX_ID version supported by QEMU is
VBE_DISPI_ID5. But currently QEMU only allows writing values up to
VBE_DISPI_ID4 to the VBE_DISPI_INDEX_ID register.
As a result of this when a lower version is written to this register and
later VBE_DISPI_ID5 is written back, reads from the register will
continue to report the lower version.
Indeed SeaBIOS is doing that during VGA initialization which causes
guests to always read VBE_DISPI_ID0 instead of the correct version.

Add helper functions to create a dmabuf for a resource and mmap it.
Also, introduce the fields blob and blob_size so that these helpers
can start to use them but the full picture will emerge only after
adding create_blob API in patch 8 of this series.
To be able to create a dmabuf using the udmabuf driver, Qemu needs
to be lauched with the memfd memory backend like this:
qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M
-machine memory-backend=mem1

Now that we have separated the gl and non-gl code flows to two different
devices there is little reason turn on and off virglrenderer usage at
runtime. The gl code can simply use virglrenderer unconditionally.
So drop use_virgl_renderer field and just do that.

Drop the virgl property, the virtio-gpu-gl-device has virgl enabled no
matter what. Just use virtio-gpu-device instead if you don't want
enable virgl and opengl. This simplifies the logic and reduces the test

dma_memory_map() may map only a part of the request. Happens if the
request can't be mapped in one go, for example due to a iommu creating
a linear dma mapping for scattered physical pages. Should that be the
case virtio-gpu must call dma_memory_map() again with the remaining
range instead of simply throwing an error.
Note that this change implies the number of iov entries may differ from
the number of mapping entries sent by the guest. Therefore the iov_len
bookkeeping needs some updates too, we have to explicitly pass around
the iov length now.

This patch adds support for the DisplayID extension, that has 2 full

Windows guests using the "Basic Display Adapter" don't parse the
"Established timings III" block. They also don't parse any edid

So prefer the "Standard Timings" block to store the display resolutions
in edid_fill_modes(). Also reorder the mode list, so more exotic
resolutions (specifically the ones which are not supported by vgabios)
are moved down and the remaining ones have a better chance to get one of

The pl110_template.h header has a doubly-nested multiple-include pattern:
* pl110.c includes it once for each host bit depth (now always 32)
* every time it is included, it includes itself 6 times, to account
for multiple guest device pixel and byte orders
Now we only have to deal with 32-bit host bit depths, we can move the
code corresponding to the outer layer of this double-nesting to be
directly in pl110.c and reduce the template header to a single layer
of nesting.

The draw_line16_32() function in the omap_lcdc template header
includes an ifdef for the case where HOST_WORDS_BIGENDIAN matches
TARGET_WORDS_BIGENDIAN. This is trying to optimise for "source
bitmap and destination bitmap format match", but it is broken,
because in this function the formats don't match: the source is
16-bit colour and the destination is 32-bit colour, so a memcpy()
will produce corrupted graphics output. Drop the bogus ifdef.
This bug was introduced in commit ea644cf343, when we dropped
support for DEPTH values other than 32 from the template header.
The old #if line was
#if DEPTH == 16 && defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN)
and this was mistakenly changed to
#if defined(HOST_WORDS_BIGENDIAN) == defined(TARGET_WORDS_BIGENDIAN)
rather than deleting the #if as now having an always-false condition.

The surfaces created with former qemu_create_message_surface
did not display the content from the guest and always contained
simple messages describing the reason.
A display backend may want to hide the window showing such a
surface. This change renames the function to
qemu_create_placeholder_surface, and adds "placeholder" flag; the
display can check the flag to decide to do anything special like
hiding the window.

Displaying rendered resources requires blocking qemu GPU to avoid extra
framebuffer copies. For an external display, via Spice currently, there
is a callback to block/unblock the rendering in the same thread.
But with the vhost-user-gpu backend, the qemu process doesn't handle
the rendering itself, and the blocking callback isn't effective.
Instead, the backend must be notified when the display code is done.
Fix this by adding a new GraphicHwOps callback to indicate the GL state
is flushed, and we are done manipulating the shared GL resources. Call
it from gtk and spice display.

In commit 2f487a3d40 we fixed a problem observed with using the
vmware-vga device and the VNC UI frontend in a belt-and-braces
manner:
* we made the VNC frontend handle non-multiple-of-16 surface widths
* we rounded up the vmware-vga display width to a multiple of 16
However this introduced a spurious dependency of a device model on a
UI frontend header. vmware-vga isn't special and should not care
about what UI frontend it is using, and the VNC frontend needs to
handle arbitrary surface widths because other display device models
could use them. Moreover, even if the maximum width in vmware-vga is
made a multiple of 16, the guest itself can always program a
different width.
Remove the dependency on the VNC header. Since we have been using
the rounded-up width value since 2014, stick with it rather than
introducing a behaviour change, but don't calculate it by rounding up
to VNC_DIRTY_BITS_PER_PIXEL any more.

Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer. The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert. Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer". It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().
The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

The S24/TCX datasheet is listed as "Unable to locate" on [1].
However the NetBSD revision 1.32 of the driver introduced
64-bit accesses to the stippler and blitter [2]. It is safe
to assume these memory regions are 64-bit accessible.
QEMU implementation is 32-bit, so fill the 'impl' fields.
Michael Lorenz (author of the NetBSD code [2]) provided us with more
information in [3]:
> IIRC the real hardware *requires* 64bit accesses for stipple and
> blitter operations to work. For stipples you write a 64bit word into
> STIP space, the address defines where in the framebuffer you want to
> draw, the data contain a 32bit bitmask, foreground colour and a ROP.
> BLIT space works similarly, the 64bit word contains an offset were to
> read pixels from, and how many you want to copy.
>
> One more thing since there seems to be some confusion - 64bit accesses
> on the framebuffer are fine as well. TCX/S24 is *not* an SBus device,
> even though its node says it is.
> S24 is a card that plugs into a special slot on the SS5 mainboard,
> which is shared with an SBus slot and looks a lot like a horizontal
> UPA slot. Both S24 and TCX are accessed through the Micro/TurboSPARC's
> AFX bus which is 64bit wide and intended for graphics.
> Early FFB docs even mentioned connecting to both AFX and UPA,
> no idea if that was ever realized in hardware though.

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:
$ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \

Some trace points are attributed to the wrong source file. Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.
Clean up with help of scripts/cleanup-trace-events.pl. Funnies
requiring manual post-processing:
* accel/tcg/cputlb.c trace points are in trace-events.
* block.c and blockdev.c trace points are in block/trace-events.
* hw/block/nvme.c uses the preprocessor to hide its trace point use
from cleanup-trace-events.pl.
* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
guard debug code.
* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.
* linux-user/trace-events abbreviates a tedious list of filenames to
*/signal.c.
* net/colo-compare and net/filter-rewriter.c use pseudo trace points
colo_compare_miscompare and colo_filter_rewriter_debug to guard
debug code.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Code simply asserts that there is no wraparound instead of handling
it properly. The assert() can be triggered by the guest (must be
privilidged inside the guest though). Fix it.

Adjust the ADDR_TO_Y() macro to extract 11 bits, which allows userspace

Simplify the code by using new introduced ADDR_TO_Y() and ADDR_TO_X()
macros. Those macros extract the x/y-coordinate from the given uint32.
As further simplification the extraction of the x/y coordinates for
VRAM_WRITE_INCR_Y and VRAM_WRITE_INCR_X can be done centrally in
vram_bit_write(), so move this code up into the function.
ADDR_TO_Y() is still limited to 10 bits which allow to address up to of
1024 lines - this will be increased in a follow-up patch.

Artist hardware is limited to 2048 x 2048 pixels.
STI ROMs allow at minimum 640 x 480 pixels.
Qemu users can adjust the screen size on the command line with:
-global artist.width=800 -global artist.height=600
but we need to ensure that the screen size stays inside the given
boundaries, otherwise print an error message and adjust.

If parts of the invalidated screen lines are outside of the VRAM buffer,
the code skips the whole invalidate. This is incorrect when only parts
of the buffer are invisble - which is the case when the mouse cursor is
