3 years agoui/console: Add placeholder flag to message surface

ui/console: Add placeholder flag to message surface

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.

3 years agoconfigure: Improve OpenGL dependency detections
Akihiko Odaki [Tue, 23 Feb 2021 06:03:07 +0000 (15:03 +0900)]
configure: Improve OpenGL dependency detections

This has the following visible changes:

- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.

The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL
and say the OpenGL displays are available along with OpenGL dma-buf
if it is present.

CharBackend's can_receive instead of assuming multiple characters can be
received. This is not an issue for e.g. the SDL UI because
qemu_chr_be_write is called with len=1 for each character (SDL sends
more than once keystroke).

ui/cocoa: Remove the uses of full screen APIs

The detections of [NSView -enterFullScreen:] and
[NSView -exitFullScreen:] were wrong. A detection is coded as:
[NSView respondsToSelector:@selector(exitFullScreenModeWithOptions:)]
but it should be:
[NSView instancesRespondToSelector:@selector(exitFullScreenModeWithOptions:)]

Because of those APIs were not detected, ui/cocoa always falled
back to a borderless window whose frame matches the screen to
implement fullscreen behavior.

The code using [NSView -enterFullScreen:] and
[NSView -exitFullScreen:] will be used if you fix the detections,
but its behavior is undesirable; the full screen view stretches
the video, changing the aspect ratio, even if zooming is disabled.

This change removes the code as it does nothing good.

According to PCI Firmware Specification[0], MMCONFIG region must be
reserved by declaring a motherboard resource. It's optional to reserve
the region in memory map by Int 15 E820h or EFIGetMemoryMap.

configuration access.

TDVF [1] [2] doesn't reserve MMCONFIG the region in memory map.
On the other hand OVMF reserves it in memory map without declaring a
motherboard resource. With memory map reservation, linux guest uses
MMCONFIG region. However it doesn't comply to PCI Firmware
specification.

This is really a problem with virtio-net failover that hotplugs a VFIO
card during the boot process. The kernel can shutdown the slot while
QEMU is hotplugging it, and this likely ends by an automatic unplug of
the card. At the end of the boot sequence the card has disappeared.

To fix that, don't set the "Link Active" state in the init function, but
rely on the plug function to do it, as the mechanism has already been
introduced by 2f2b18f60bf1.

failover: really display a warning when the primary device is not found

In failover_add_primary(), we search the id of the failover device by
scanning the list of the devices in the opts list to find a device with
a failover_pair_id equals to the id of the virtio-net device.

If the failover_pair_id is not found, QEMU ignores the primary
device silently (which also means it will not be hidden and
it will be enabled directly at boot).

After that, we search the id in the opts list to do a qdev_device_add()
with it. The device will be always found as otherwise we had exited
before, and thus the warning is never displayed.

Fix that by moving the error report to the first exit condition.
Also add a g_assert() to be sure the compiler will not complain
about a possibly NULL pointer.

Commit a1190ab628 has added a "allow_unplug_during_migration = true" at
the end of the main "if" block, so it is not needed to set it anymore

vt82c686: Move superio memory region to SuperIOConfig struct

The superio memory region holds the io space index/data registers used
to access the superio config registers that are implemented in struct
SuperIOConfig. To keep these related things together move the memory

Also remove the unused "data" member of SuperIOConfig which is not
