2021-03-04ui/console: Pass placeholder surface to displaysAkihiko Odaki1-5/+2
ui/console used to accept NULL as graphic console surface, but its semantics was inconsistent among displays: - cocoa and gtk-egl perform NULL dereference. - egl-headless, spice and spice-egl do nothing. - gtk releases underlying resources. - sdl2-2d and sdl2-gl destroys the window. - vnc shows a message, "Display output is not active." Fortunately, only virtio-gpu and virtio-gpu-3d assign NULL so we can study them to figure out the desired behavior. They assign NULL *except* for the primary display when the device is realized, reset, or its scanout is disabled. This effectively destroys windows for the (uninitialized) secondary displays. To implement the consistent behavior of display device realization/reset, this change embeds it to the operation switching the surface. When NULL was given as a new surface when switching, ui/console will instead passes a placeholder down to each display listeners. sdl destroys the window for a secondary console if its surface is a placeholder. The other displays simply shows the placeholder.

2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster1-1/+0
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

2018-10-12sdl2: Support all virtio-gpu formatsMax Reitz1-0/+15
There are some 2D resource formats that can be used through virtio-gpu, but which are not supported by SDL2 when used for a scanout; these are all alpha-channel formats and also XBGR (RGBX in non-BE pixman). Add these formats in the switch converting pixman to SDL format constants so a guest cannot crash the VM by triggering the g_assert_not_reached() with an unsupported format.

2018-02-16sdl: restore optimized redrawAnatoly Trosinenko1-16/+7
The documentation on SDL_RenderPresent function states that "the backbuffer should be considered invalidated after each present", so copy the entire texture on each redraw. On the other hand, SDL_UpdateTexture function is described as "fairly slow function", so restrict it to just the changed pixels. Also added SDL_RenderClear call, as suggested in the documentation page on SDL_RenderPresent.
