2023-07-17virtio-gpu-udmabuf: correct naming of QemuDmaBuf size propertiesDongwon Kim
Replace 'width' and 'height' in QemuDmaBuf with 'backing_widht' and 'backing_height' as these commonly indicate the size of the whole surface (e.g. guest's Xorg extended display). Then use 'width' and 'height' for sub region in there (e.g. guest's scanouts).

2023-07-17virtio-gpu: replace the surface with null surface when resettingDongwon Kim
The primary guest scanout shows the booting screen right after reboot 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 virtio-gpu device. 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.

2023-06-02cutils: Adjust signature of parse_uint[_full]Eric Blake
It's already confusing that we have two very similar functions for wrapping the parse of a 64-bit unsigned value, differing mainly on whether they permit leading '-'. Adjust the signature of parse_uint() and parse_uint_full() to be like all of qemu_strto*(): put the result parameter last, use the same types (uint64_t and unsigned long long have the same width, but are not always the same type), and mark endptr const (this latter change only affects the rare caller of parse_uint). Adjust all callers in the tree. While at it, note that since cutils.c already includes: QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long)); we are guaranteed that the result of parse_uint* cannot exceed UINT64_MAX (or the build would have failed), so we can drop pre-existing dead comparisons in opts-visitor.c that were never false.

2023-05-28ui/sdl2: disable SDL_HINT_GRAB_KEYBOARD on WindowsVolker Rümelin
Windows sends an extra left control key up/down input event for every right alt key up/down input event for keyboards with international layout. Since commit 830473455f ("ui/sdl2: fix handling of AltGr key on Windows") QEMU uses a Windows low level keyboard hook procedure to reliably filter out the special left control key and to grab the keyboard on Windows. The SDL2 version 2.0.16 introduced its own Windows low level keyboard hook procedure to grab the keyboard. Windows calls this callback before the QEMU keyboard hook procedure. This disables the special left control key filter when the keyboard is grabbed. To fix the problem, disable the SDL2 Windows low level keyboard hook procedure.

2023-05-28ui/gtk: use widget size for cursor motion eventErico Nunes
The gd_motion_event size has some calculations for the cursor position, which also take into account things like different size of the framebuffer compared to the window size. The use of window size makes things more difficult though, as at least in the case of Wayland includes the size of ui elements like a menu bar at the top of the window. This leads to a wrong position calculation by a few pixels. Fix it by using the size of the widget, which already returns the size of the actual space to render the framebuffer.

2023-05-28ui/gtk: fix passing y0_top parameter to scanoutErico Nunes
The dmabuf->y0_top flag is passed to .dpy_gl_scanout_dmabuf(), however in the gtk ui both implementations dropped it when doing the next scanout_texture call. Fixes flipped linux console using vhost-user-gpu with the gtk ui display.

By using a subproject, our own meson.build can use variables from the subproject instead of hard-coded paths. This is also the first step towards managing downloads with .wrap files instead of submodule. Reviewed-by: Daniel P. Berrangé <berrange@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-05-12ui: Fix pixel colour channel order for PNG screenshotsPeter Maydell
When we take a PNG screenshot the ordering of the colour channels in the data is not correct, resulting in the image having weird colouring compared to the actual display. (Specifically, on a little-endian host the blue and red channels are swapped; on big-endian everything is wrong.) This happens because the pixman idea of the pixel data and the libpng idea differ. PIXMAN_a8r8g8b8 defines that pixels are 32-bit values, with A in bits 24-31, R in bits 16-23, G in bits 8-15 and B in bits 0-7. This means that on little-endian systems the bytes in memory are B G R A and on big-endian systems they are A R G B libpng, on the other hand, thinks of pixels as being a series of values for each channel, so its format PNG_COLOR_TYPE_RGB_ALPHA always wants bytes in the order R G B A This isn't the same as the pixman order for either big or little endian hosts. The alpha channel is also unnecessary bulk in the output PNG file, because there is no alpha information in a screenshot. To handle the endianness issue, we already define in ui/qemu-pixman.h various PIXMAN_BE_* and PIXMAN_LE_* values that give consistent byte-order pixel channel formats. So we can use PIXMAN_BE_r8g8b8 and PNG_COLOR_TYPE_RGB, which both have an in-memory byte order of R G B and 3 bytes per pixel. (PPM format screenshots get this right; they already use the PIXMAN_BE_r8g8b8 format.)
