From ccf0566ca462a982cf84703d2278af0917cf816c Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Tue, 16 May 2017 06:30:39 -0700 Subject: [PATCH] SDL - add SDL_WINDOW_VULKAN and make Android_CreateWindow only create an EGLSurface when SDL_WINDOW_VULKAN is not present. This makes it so the ANativeWindow* can be used with vkCreateAndroidSurfaceKHR, otherwise it will fail because having both an EGLSurface and VkSurfaceKHR attached to a window is not allowed according to the Vulkan spec: "In particular, only one VkSurfaceKHR can exist at a time for a given window. Similarly, a native window cannot be used by both a VkSurfaceKHR and EGLSurface simultaneously" CR: SamL --- include/SDL_video.h | 3 ++- src/video/SDL_video.c | 2 +- src/video/android/SDL_androidwindow.c | 16 ++++++++++------ 3 files changed, 13 insertions(+), 8 deletions(-) diff --git a/include/SDL_video.h b/include/SDL_video.h index cd20f9b94..bee524123 100644 --- a/include/SDL_video.h +++ b/include/SDL_video.h @@ -116,7 +116,8 @@ typedef enum SDL_WINDOW_SKIP_TASKBAR = 0x00010000, /**< window should not be added to the taskbar */ SDL_WINDOW_UTILITY = 0x00020000, /**< window should be treated as a utility window */ SDL_WINDOW_TOOLTIP = 0x00040000, /**< window should be treated as a tooltip */ - SDL_WINDOW_POPUP_MENU = 0x00080000 /**< window should be treated as a popup menu */ + SDL_WINDOW_POPUP_MENU = 0x00080000, /**< window should be treated as a popup menu */ + SDL_WINDOW_VULKAN = 0x00100000 /**< window usable for Vulkan surface */ } SDL_WindowFlags; /** diff --git a/src/video/SDL_video.c b/src/video/SDL_video.c index de588e4ad..7e0e5ac86 100644 --- a/src/video/SDL_video.c +++ b/src/video/SDL_video.c @@ -1321,7 +1321,7 @@ SDL_UpdateFullscreenMode(SDL_Window * window, SDL_bool fullscreen) } #define CREATE_FLAGS \ - (SDL_WINDOW_OPENGL | SDL_WINDOW_BORDERLESS | SDL_WINDOW_RESIZABLE | SDL_WINDOW_ALLOW_HIGHDPI | SDL_WINDOW_ALWAYS_ON_TOP | SDL_WINDOW_SKIP_TASKBAR | SDL_WINDOW_POPUP_MENU | SDL_WINDOW_UTILITY | SDL_WINDOW_TOOLTIP) + (SDL_WINDOW_OPENGL | SDL_WINDOW_BORDERLESS | SDL_WINDOW_RESIZABLE | SDL_WINDOW_ALLOW_HIGHDPI | SDL_WINDOW_ALWAYS_ON_TOP | SDL_WINDOW_SKIP_TASKBAR | SDL_WINDOW_POPUP_MENU | SDL_WINDOW_UTILITY | SDL_WINDOW_TOOLTIP | SDL_WINDOW_VULKAN ) static void SDL_FinishWindowCreation(SDL_Window *window, Uint32 flags) diff --git a/src/video/android/SDL_androidwindow.c b/src/video/android/SDL_androidwindow.c index c6da5b705..68bc7a77f 100644 --- a/src/video/android/SDL_androidwindow.c +++ b/src/video/android/SDL_androidwindow.c @@ -69,13 +69,17 @@ Android_CreateWindow(_THIS, SDL_Window * window) SDL_free(data); return SDL_SetError("Could not fetch native window"); } - - data->egl_surface = SDL_EGL_CreateSurface(_this, (NativeWindowType) data->native_window); - if (data->egl_surface == EGL_NO_SURFACE) { - ANativeWindow_release(data->native_window); - SDL_free(data); - return SDL_SetError("Could not create GLES window surface"); + /* Do not create EGLSurface for Vulkan window since it will then make the window + incompatible with vkCreateAndroidSurfaceKHR */ + if ((window->flags & SDL_WINDOW_VULKAN) == 0) { + data->egl_surface = SDL_EGL_CreateSurface(_this, (NativeWindowType) data->native_window); + + if (data->egl_surface == EGL_NO_SURFACE) { + ANativeWindow_release(data->native_window); + SDL_free(data); + return SDL_SetError("Could not create GLES window surface"); + } } window->driverdata = data;
