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

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.

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).

The code should check the opposite condition of res->iov because it will be null
if virtio_gpu_create_mapping_iov fails and actually this checking is not even
required because checking on ret covers all failing cases.

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).

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

"3d" -> "virgl" as 3d is a rather broad term.
Hopefully a bit less confusing.

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.

The Detailed Timing Descriptor has only 12 bits to store the
resolution. This limits the guest to 4095 pixels.
This patch adds support for the DisplayID extension, that has 2 full
bytes for that purpose, thus allowing 5k resolutions and above.

Some of the EDID extensions like DisplayID do checksums of their
subsections. Currently checksums can be only applied to the whole
extension blocks which are 128 bytes.
This patch allows to checksum arbitrary parts of EDID, and not only
whole extension blocks.

The timing generation is currently performed inside the function that
fills in the DTD. The DisplayID generation needs it as well, so moving
it out to a separate function.

When the 4 descriptors in the base edid block are filled, jump to the
dta extension block. This allows for more than four descriptors.
Happens for example when generating an edid blob with a serial number
(qemu-edid -s $serial).

Initialize the "Established timings III" block earlier. Also move up
edid_fill_modes(). That'll make sure the offset for the additional
descriptors in the dta block don't move any more, which in turn makes it
easier to actually use them.
