Hmm, I guess we can skip pretty much all of the init in case there are
no outputs:
@@ -794,6 +794,9 @@ void sdl_display_init(DisplayState *ds, int
full_screen, int no_frame)
}
}
sdl2_num_outputs = i;
+ if (sdl2_num_outputs == 0) {
+ return;
+ }
sdl2_console = g_new0(struct sdl2_console, sdl2_num_outputs);
for (i = 0; i < sdl2_num_outputs; i++) {
QemuConsole *con = qemu_console_lookup_by_index(i);
Maybe even move up the loop counting the outputs, so we can skip the
SDL_Init() call too. We don't get a empty window then.
cheers,
Gerd
