Implementing RAMFB migration is quite straightforward. One caveat is to
treat the whole RAMFBCfg as a blob, since that's what is exposed to the
guest directly. This avoid having to fiddle with endianness issues if we
were to migrate fields individually as integers.
The devices using RAMFB will have to include ramfb_vmstate in their
migration description.

This adds initial support for gfxstream and cross-domain. Both
features rely on virtio-gpu blob resources and context types, which
are also implemented in this patch.
gfxstream has a long and illustrious history in Android graphics
paravirtualization. It has been powering graphics in the Android
Studio Emulator for more than a decade, which is the main developer
platform.
Originally conceived by Jesse Hall, it was first known as "EmuGL" [a].
The key design characteristic was a 1:1 threading model and
auto-generation, which fit nicely with the OpenGLES spec. It also
allowed easy layering with ANGLE on the host, which provides the GLES
implementations on Windows or MacOS enviroments.
gfxstream has traditionally been maintained by a single engineer, and
between 2015 to 2021, the goldfish throne passed to Frank Yang.
Historians often remark this glorious reign ("pax gfxstreama" is the
academic term) was comparable to that of Augustus and both Queen
Elizabeths. Just to name a few accomplishments in a resplendent
panoply: higher versions of GLES, address space graphics, snapshot
support and CTS compliant Vulkan [b].
One major drawback was the use of out-of-tree goldfish drivers.
Android engineers didn't know much about DRM/KMS and especially TTM so
a simple guest to host pipe was conceived.
Luckily, virtio-gpu 3D started to emerge in 2016 due to the work of
the Mesa/virglrenderer communities. In 2018, the initial virtio-gpu
port of gfxstream was done by Cuttlefish enthusiast Alistair Delva.
It was a symbol compatible replacement of virglrenderer [c] and named
"AVDVirglrenderer". This implementation forms the basis of the
current gfxstream host implementation still in use today.
cross-domain support follows a similar arc. Originally conceived by
Wayland aficionado David Reveman and crosvm enjoyer Zach Reizner in
2018, it initially relied on the downstream "virtio-wl" device.
In 2020 and 2021, virtio-gpu was extended to include blob resources
and multiple timelines by yours truly, features gfxstream/cross-domain
both require to function correctly.
Right now, we stand at the precipice of a truly fantastic possibility:
the Android Emulator powered by upstream QEMU and upstream Linux
kernel. gfxstream will then be packaged properfully, and app
developers can even fix gfxstream bugs on their own if they encounter
them.
It's been quite the ride, my friends. Where will gfxstream head next,
nobody really knows. I wouldn't be surprised if it's around for
another decade, maintained by a new generation of Android graphics
enthusiasts.
Technical details:
- Very simple initial display integration: just used Pixman
- Largely, 1:1 mapping of virtio-gpu hypercalls to rutabaga function
calls
Next steps for Android VMs:
- The next step would be improving display integration and UI interfaces
with the goal of the QEMU upstream graphics being in an emulator
release [d].
Next steps for Linux VMs for display virtualization:
- For widespread distribution, someone needs to package Sommelier or the
wayland-proxy-virtwl [e] ideally into Debian main. In addition, newer
versions of the Linux kernel come with DRM_VIRTIO_GPU_KMS option,
which allows disabling KMS hypercalls. If anyone cares enough, it'll
probably be possible to build a custom VM variant that uses this display
virtualization strategy.

The fw_cfg DMA write callback in ramfb prepares a new display surface in
QEMU; this new surface is put to use ("swapped in") upon the next display
update. At that time, the old surface (if any) is released.
If the guest triggers the fw_cfg DMA write callback at least twice between
two adjacent display updates, then the second callback (and further such
callbacks) will leak the previously prepared (but not yet swapped in)
display surface.
The issue can be shown by:
(1) starting QEMU with "-trace displaysurface_free", and
(2) running the following program in the guest UEFI shell:
> #include <Library/ShellCEntryLib.h> // ShellAppMain()
> #include <Library/UefiBootServicesTableLib.h> // gBS
> #include <Protocol/GraphicsOutput.h> // EFI_GRAPHICS_OUTPUT_PROTOCOL
>
> INTN
> EFIAPI
> ShellAppMain (
> IN UINTN Argc,
> IN CHAR16 **Argv
> )
> {
> EFI_STATUS Status;
> VOID *Interface;
> EFI_GRAPHICS_OUTPUT_PROTOCOL *Gop;
> UINT32 Mode;
>
> Status = gBS->LocateProtocol (
> &gEfiGraphicsOutputProtocolGuid,
> NULL,
> &Interface
> );
> if (EFI_ERROR (Status)) {
> return 1;
> }
>
> Gop = Interface;
>
> Mode = 1;
> for ( ; ;) {
> Status = Gop->SetMode (Gop, Mode);
> if (EFI_ERROR (Status)) {
> break;
> }
>
> Mode = 1 - Mode;
> }
>
> return 1;
> }
The symptom is then that:
- only one trace message appears periodically,
- the time between adjacent messages keeps increasing -- implying that
some list structure (containing the leaked resources) keeps growing,
- the "surface" pointer is ever different.

We figured this wasn't a CVE-worthy problem, as only small amounts of
memory were leaked (the framebuffer itself is mapped from guest RAM, QEMU
only allocates administrative structures), plus libvirt restricts QEMU
memory footprint anyway, thus the guest can only DoS itself.
Plug the leak, by releasing the last prepared (not yet swapped in) display
surface, if any, in the fw_cfg DMA write callback.
Regarding the "reproducer", with the fix in place, the log is flooded with
trace messages (one per fw_cfg write), *and* the trace message alternates
between just two "surface" pointer values (i.e., nothing is leaked, the
allocator flip-flops between two objects in effect).
This issue appears to date back to the introducion of ramfb (995b30179b,
"hw/display: add ramfb, a simple boot framebuffer living in guest ram",
2018-06-18).

Calling OpenGL from different threads can have bad consequences if not
carefully reviewed. It's not generally supported. In my case, I was
debugging a crash in glDeleteTextures from OPENGL32.DLL, where I asked
qemu for gl=es, and thus ANGLE implementation was expected. libepoxy did
resolution of the global pointer for glGenTexture to the GLES version
from the main thread. But it resolved glDeleteTextures to the GL
version, because it was done from a different thread without correct
context. Oops.
Let's stick to the main thread for GL calls by using a BH.
Note: I didn't use atomics for reset_finished check, assuming the BQL

but additional guest displays (i.e. max_ouptuts > 1) will keep displaying
the old frames until the guest virtio gpu driver gets initialized, which
could cause some confusion. A better way is to to replace the surface with
a place holder that tells the display is not active during the reset of

And to immediately update the surface with the place holder image after
the switch, displaychangelistener_gfx_switch needs to be called with
'update == TRUE' in dpy_gfx_replace_surface when the new surface is NULL.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.

It looks like the virtio_gpu_load() does not compute and set the offset,
the same way virtio_gpu_set_scanout() does. This probably results in
incorrect display until the scanout/framebuffer is updated again, I
guess we should fix it, although I haven't checked this yet.

As Coverity points out (CID 1508621) the calculation to increment i in
the fill fallback loop is ineffective as it is overwritten in next
statement. This was left there by mistake from a previous version but
is not needed in the current approach so remove the superfluous
increment statement.

The 'hwaddr' type is defined in "exec/hwaddr.h" as:
hwaddr is the type of a physical address
(its size can be different from 'target_ulong').
All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:
$ fgrep define include/exec/hwaddr.h
#define HWADDR_H
#define HWADDR_BITS 64
#define HWADDR_MAX UINT64_MAX
#define TARGET_FMT_plx "%016" PRIx64
^^^^^^
#define HWADDR_PRId PRId64
#define HWADDR_PRIi PRIi64
#define HWADDR_PRIo PRIo64
#define HWADDR_PRIu PRIu64
#define HWADDR_PRIx PRIx64
#define HWADDR_PRIX PRIX64
Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:
$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
#define TARGET_FMT_lx "%08x"
#define TARGET_FMT_ld "%d"
#define TARGET_FMT_lu "%u"
#define TARGET_FMT_lx "%016" PRIx64
#define TARGET_FMT_ld "%" PRId64
#define TARGET_FMT_lu "%" PRIu64
Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:
$ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

When using --disable-virglrenderer, QEMU still creates
hw-display-virtio-gpu-gl.so
hw-display-virtio-vga-gl.so
hw-display-virtio-gpu-pci-gl.so
but when these are loaded, they provide no functionality as the code
which registers types is not compiled in. Funtionally this is
relatively harmless, because QEMU is fine loading a module with no
types.
This is rather confusing for users and OS distro maintainers though,
as they think they have the GL functionality built, but in fact the
module they are looking at provides nothing of value.
The root cause is the use of 'when/if_true' rules when adding sources
to the module source set. If all the rules evaluate to false, then we
have declared the module, but not added anything to it. We need to
put declaration of the entire module inside a condition based on
existance of the 3rd party library deps that are mandatory.

To support configure interrupt for vhost-vdpa
Introduce VIRTIO_CONFIG_IRQ_IDX -1 as configure interrupt's queue index,
Then we can reuse the functions guest_notifier_mask and guest_notifier_pending.
Add the check of queue index in these drivers, if the driver does not support
configure interrupt, the function will just return

It seems a little bit weird that the para-virtualized x86 VMWare
devices "vmware-svga" and "vmxnet3" also show up in non-x86 targets.
They are likely pretty useless there (since the guest OSes likely
do not have any drivers for those enabled), so let's change this and
only enable those devices by default for the classical x86 targets.

Similarly qxl_phys2virt() now returns NULL in such case, and

In order to do so in the next commit, pass the buffer size

For QXLCursor in qxl_render_cursor() -> qxl_cursor() we
verify the size of the chunked data ahead, checking we can

Since in the SPICE_CURSOR_TYPE_MONO case the cursor is

We do not expect any functional change in any ACPI tables with this
change. It's only a refactoring.
NB2:
Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them.
However, modules are reused between all architectures so CONFIG_ACPI is
on. For those architectures, dummy stub function definitions help to
resolve symbols. This change uses more of these and so it adds a couple
of dummy stub definitions so that symbols for those can be resolved.

by socketpair() at default, the fds will survive across exec' function.
In the case that exec' function get invoked, such as the live-update feature

When in CGA modes, QEMU wants to ignore the maximum scan field (bits 0..4) of
the maximum scan length register in the CRTC. It is not clear why this is
needed---for example, Bochs ignores bit 7 instead. The issue is that the
CGA modes are not detected correctly, and in particular mode 6 results in
multi_scan==3 according to how SeaBIOS programs it. The right way to check
for CGA graphics modes is to check whether bit 13 of the address is special
cased by the CRT controller to achieve line interleaving, i.e. whether bit 0
of the CRTC mode control register is clear.

This patch fixes the dedicated framebuffer mailbox interface by
removing an unneeded offset. This means that we pick the framebuffer
address in the same way that we do if the guest code uses the buffer
allocate mechanism of the bcm2835_property interface (case
0x00040001: /* Allocate buffer */ in bcm2835_property.c).
The documentation of this mailbox interface doesn't say anything
about using parts of the request buffer address to affect the
chosen framebuffer address:
https://github.com/raspberrypi/firmware/wiki/Mailbox-framebuffer-interface
Some baremetal applications like the Screen01/Screen02 examples from

Add an asynchronous version of i2c_send() that requires the slave to
explicitly acknowledge on the bus with i2c_ack().
The current master must use the new i2c_start_send_async() to indicate
that it wants to do an asynchronous transfer. This allows the i2c core
to check if the target slave supports this or not. This approach relies
on adding a new enum i2c_event member, which is why a bunch of other
devices needs changes in their event handling switches.

This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
a guests is typically not designed to respond to frequent
refresh rate changes, or frequent "display mode" changes in
general. The frequency of refresh rate changes of the physical
display backend matches better to the guest's expectation.
QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.
