1333fd0693 virtio-gpu: Register capsets dynamically
virtio_gpu_virgl_get_num_capsets will return "num_capsets", but we can't
assume that capset_index 1 is always VIRGL2 once we'll support more capsets,
like Venus and DRM capsets. Register capsets dynamically to avoid that problem.

6a3e00d8c9 virtio-gpu: Don't require udmabuf when blobs and virgl are enabled
The udmabuf usage is mandatory when virgl is disabled and blobs feature
enabled in the Qemu machine configuration. If virgl and blobs are enabled,
then udmabuf requirement is optional. Since udmabuf isn't widely supported
by a popular Linux distros today, let's relax the udmabuf requirement for
blobs=on,virgl=on. Now, a full-featured virtio-gpu acceleration is
available to Qemu users without a need to have udmabuf available in the
system.

330ef31deb ui/win32: fix potential use-after-free with dbus shared memory
DisplaySurface may be free before the pixman image is freed, since the
image is refcounted and used by different objects, including pending
dbus messages.

Furthermore, setting the destroy function in
create_displaysurface_from() isn't appropriate, as it may not be used,
and may be overriden as in ramfb.

Set the destroy function when the shared handle is set, use the HANDLE
directly for destroy data, using a single common helper
qemu_pixman_win32_image_destroy().

7e6b5497ea hw/char: Extract serial-mm
hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

  # grep -r -e "select SERIAL" | grep -v SERIAL_
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"

  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"

00adced5c3 virtio: Allow .get_vhost() without vhost_started
Historically, .get_vhost() was probably only called when
vdev->vhost_started is true.  However, we now decidedly want to call it
also when vhost_started is false, specifically so we can issue a reset
to the vhost back-end while device operation is stopped.

Some .get_vhost() implementations dereference some pointers (or return
offsets from them) that are probably guaranteed to be non-NULL when
vhost_started is true, but not necessarily otherwise.  This patch makes
all such implementations check all such pointers, returning NULL if any
is NULL.

0fa57cbfa7 hw/display/virtio-gpu: Improve "opengl is not available" error message
If the user tries to use the virtio-gpu-gl device but the display
backend doesn't have OpenGL support enabled, we currently print a
rather uninformative error message:

$ qemu-system-aarch64 -M virt -device virtio-gpu-gl
qemu-system-aarch64: -device virtio-gpu-gl: opengl is not available

Since OpenGL is not enabled on display frontends by default, users
are quite likely to run into this. Improve the error message to
be more specific and to suggest to the user a path forward.

Note that the case of "user tried to enable OpenGL but the display
backend doesn't handle it" is caught elsewhere first, so we can
assume that isn't the problem:

$ qemu-system-aarch64 -M virt -device virtio-gpu-gl -display curses,gl=on
qemu-system-aarch64: OpenGL is not supported by the display

(Use of error_append_hint() requires us to add an ERRP_GUARD() to
the function, as noted in include/qapi/error.h.)

With this commit we now produce the hopefully more helpful error:
$ ./build/x86/qemu-system-aarch64 -M virt -device virtio-gpu-gl
qemu-system-aarch64: -device virtio-gpu-gl: The display backend does not have OpenGL support enabled
It can be enabled with '-display BACKEND,gl=on' where BACKEND is the name of the display backend to use.

345acc4439 hw/display/bcm2835_fb: fix fb_use_offsets condition
It is common practice when implementing double-buffering on VideoCore
to do so by multiplying the height of the virtual buffer by the
number of virtual screens desired (i.e., two - in the case of
double-bufferring).

At present, this won't work in QEMU because the logic in
fb_use_offsets require that both the virtual width and height exceed
their physical counterparts.

This appears to be unintentional/a typo and indeed the comment
states; "Experimentally, the hardware seems to do this only if the
viewport size is larger than the physical screen".  The
viewport/virtual size would be larger than the physical size if
either virtual dimension were larger than their physical counterparts
and not necessarily both.

4bba839808 ui/console: Remove dpy_cursor_define_supported()
Remove dpy_cursor_define_supported() as it brings no benefit today and
it has a few inherent problems.

All graphical displays except egl-headless support cursor composition
without DMA-BUF, and egl-headless is meant to be used in conjunction
with another graphical display, so dpy_cursor_define_supported()
always returns true and meaningless.

Even if we add a new display without cursor composition in the future,
dpy_cursor_define_supported() will be problematic as a cursor display
fix for it because some display devices like virtio-gpu cannot tell the
lack of cursor composition capability to the guest and are unable to
utilize the value the function returns. Therefore, all non-headless
graphical displays must actually implement cursor composition for
correct cursor display.

Another problem with dpy_cursor_define_supported() is that it returns
true even if only some of the display listeners support cursor
composition, which is wrong unless all display listeners that lack
cursor composition is headless.

c0fcd6334f ui/console: Use qemu_dmabuf_new() and free() helpers instead
This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.

v7: remove prefix, "dpy_gl_" from all helpers
    qemu_dmabuf_free() returns without doing anything if input is null
    (Daniel P. Berrangé <berrange@redhat.com>)
    call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
    (Daniel P. Berrangé <berrange@redhat.com>)

v8: Introduction of helpers was removed as those were already added
    by the previous commit

v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
    virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c

    removed unnecessary spaces were accidently added in the patch,
    'ui/console: Use qemu_dmabuf_new() a...'

v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
     done in qemu_dmabuf_free anyway.
     (Daniel P. Berrangé <berrange@redhat.com>)

v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
         do it.

     --- 'dmabuf' is now allocated space so it should be freed at the end of
         dbus_scanout_texture

v13: --- Immediately free dmabuf after it is released to prevent possible
         leaking of the ptr
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

     --- Use g_autoptr macro to define *dmabuf for auto clean up instead of
         calling qemu_dmabuf_free
         (Marc-André Lureau <marcandre.lureau@redhat.com>)

v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
         as it was done because of some misunderstanding (v13).

     --- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
         to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
         happens (before new dmabuf is allocated). Otherwise, it would cause
         invalid memory access when the same function is executed. Also NULL
         check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

88f5ed7017 xen: register legacy backends via xen_backend_init
It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.

This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init().  It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.
