2024-06-06ui/sdl2: Allow host to power down screenBernhard Beschow
By default, SDL disables the screen saver which prevents the host from powering down the screen even if the screen is locked. This results in draining the battery needlessly when the host isn't connected to a wall charger. Fix that by enabling the screen saver.

2024-05-27ui/gtk: Fix mouse/motion event scaling issue with GTK display backendhikalium
Remove gtk_widget_get_scale_factor() usage from the calculation of the motion events in the GTK backend to make it work correctly on environments that have `gtk_widget_get_scale_factor() != 1`. This scale factor usage had been introduced in the commit f14aab420c and at that time the window size was used for calculating the things and it was working correctly. However, in the commit 2f31663ed4 the logic switched to use the widget size instead of window size and because of the change the usage of scale factor becomes invalid (since widgets use `vc->gfx.scale_{x, y}` for scaling). Tested on Crostini on ChromeOS (15823.51.0) with an external display.

2024-03-09ui/cocoa: Fix window clipping on macOS 14David Parsons
macOS Sonoma changes the NSView.clipsToBounds to false by default where it was true in earlier version of macOS. This causes the window contents to be occluded by the frame at the top of the window. This fixes the issue by conditionally compiling the clipping on Sonoma to true. NSView only exposes the clipToBounds in macOS 14 and so has to be fixed via conditional compilation.

2024-02-20ui/console: Fix console resize with placeholder surfaceTianlan Zhou
In `qemu_console_resize()`, the old surface of the console is keeped if the new console size is the same as the old one. If the old surface is a placeholder, and the new size of console is the same as the placeholder surface (640*480), the surface won't be replace. In this situation, the surface's `QEMU_PLACEHOLDER_FLAG` flag is still set, so the console won't be displayed in SDL display mode.

2024-02-20ui/clipboard: mark type as not available when there is no dataFiona Ebner
With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT message with len=0. In qemu_clipboard_set_data(), the clipboard info will be updated setting data to NULL (because g_memdup(data, size) returns NULL when size is 0). If the client does not set the VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then the 'request' callback for the clipboard peer is not initialized. Later, because data is NULL, qemu_clipboard_request() can be reached via vdagent_chr_write() and vdagent_clipboard_recv_request() and there, the clipboard owner's 'request' callback will be attempted to be called, but that is a NULL pointer. In particular, this can happen when using the KRDC (22.12.3) VNC client. Another scenario leading to the same issue is with two clients (say noVNC and KRDC): The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and initializes its cbpeer. The KRDC client does not, but triggers a vnc_client_cut_text() (note it's not the _ext variant)). There, a new clipboard info with it as the 'owner' is created and via qemu_clipboard_set_data() is called, which in turn calls qemu_clipboard_update() with that info. In qemu_clipboard_update(), the notifier for the noVNC client will be called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the noVNC client. The 'owner' in that clipboard info is the clipboard peer for the KRDC client, which did not initialize the 'request' function. That sounds correct to me, it is the owner of that clipboard info. Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it passes), that clipboard info is passed to qemu_clipboard_request() and the original segfault still happens. Fix the issue by handling updates with size 0 differently. In particular, mark in the clipboard info that the type is not available. While at it, switch to g_memdup2(), because g_memdup() is deprecated.

Commit 6f189a08c1 ("ui/gtk-egl: Check EGLSurface before doing scanout") introduced a regression when QEMU is running with a virtio-gpu-gl-device on a host under X11. After the guest has initialized the virtio-gpu-gl-device, the guest screen only shows "Display output is not active.". Commit 6f189a08c1 moved all function calls in gd_egl_scanout_texture() to a code path which is only called once after gd_egl_init() succeeds in gd_egl_scanout_texture(). Move all function calls in gd_egl_scanout_texture() back to the regular code path so they get always called if one of the gd_egl_init() calls was successful.

2023-12-20ui/gtk-egl: Check EGLSurface before doing scanoutAntonio Caggiano
The first time gd_egl_scanout_texture() is called, there's a possibility that the GTK drawing area might not be realized yet, in which case its associated GdkWindow is NULL. This means gd_egl_init() was also skipped and the EGLContext and EGLSurface stored in the VirtualGfxConsole are not valid yet. Continuing with the scanout in this conditions would result in hitting an assert in libepoxy: "Couldn't find current GLX or EGL context". A possible workaround is to just ignore the scanout request, giving the the GTK drawing area some time to finish its realization. At that point, the gd_egl_init() will succeed and the EGLContext and EGLSurface stored in the VirtualGfxConsole will be valid.

2023-05-31ui/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.

2023-05-18ui: 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.)

2023-04-27vnc: avoid underflow when accessing user-provided addressPaolo Bonzini
If hostlen is zero, there is a possibility that addrstr[hostlen - 1] underflows and, if a closing bracked is there, hostlen - 2 is passed to g_strndup() on the next line. If websocket==false then addrstr[0] would be a colon, but if websocket==true this could in principle happen. Fix it by checking hostlen. Reported by Coverity.

2022-11-23ui/gtk: prevent ui lock up when dpy_gl_update called again before current ↵Dongwon Kim
draw event occurs A warning, "qemu: warning: console: no gl-unblock within" followed by guest scanout lockup can happen if dpy_gl_update is called in a row and the second call is made before gd_draw_event scheduled by the first call is taking place. This is because draw call returns without decrementing gl_block ref count if the dmabuf was already submitted as shown below. (gd_gl_area_draw/gd_egl_draw) if (dmabuf) { if (!dmabuf->draw_submitted) { return; } else { dmabuf->draw_submitted = false; } } So it should not schedule any redundant draw event in case draw_submitted is already set in gd_egl_fluch/gd_gl_area_scanout_flush.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana
improve error handling during module load, by changing: bool module_load(const char *prefix, const char *lib_name); void module_load_qom(const char *type); to: int module_load(const char *prefix, const char *name, Error **errp); int module_load_qom(const char *type, Error **errp); where the return value is: -1 on module load error, and errp is set with the error 0 on module or one of its dependencies are not installed 1 on module load success 2 on module load success (module already loaded or built-in) module_load_qom_one has been introduced in: commit 28457744c345 ("module: qom module support"), which built on top of module_load_one, but discarded the bool return value. Restore it. Adapt all callers to emit errors, or ignore them, or fail hard, as appropriate in each context. Replace the previous emission of errors via fprintf in _some_ error conditions with Error and error_report, so as to emit to the appropriate target. A memory leak is also fixed as part of the module_load changes. audio: when attempting to load an audio module, report module load errors. Note that still for some callers, a single issue may generate multiple error reports, and this could be improved further. Regarding the audio code itself, audio_add() seems to ignore errors, and this should probably be improved. block: when attempting to load a block module, report module load errors. For the code paths that already use the Error API, take advantage of those to report module load errors into the Error parameter. For the other code paths, we currently emit the error, but this could be improved further by adding Error parameters to all possible code paths. console: when attempting to load a display module, report module load errors. qdev: when creating a new qdev Device object (DeviceState), report load errors. If a module cannot be loaded to create that device, now abort execution (if no CONFIG_MODULE) or exit (if CONFIG_MODULE). qom/object.c: when initializing a QOM object, or looking up class_by_name, report module load errors. qtest: when processing the "module_load" qtest command, report errors in the load of the module.
