From 9373447a614e7b401919328b589b5f2607e456fd Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Fri, 5 Mar 2010 11:18:16 +0800 Subject: [PATCH] st/egl: Add support for EGL_KHR_image_base and EGL_KHR_image_pixmap. These extensions are not quite useful until the client APIs gain support for the respective EGLImage extensions. --- src/gallium/state_trackers/egl/common/egl_g3d.c | 14 ++- src/gallium/state_trackers/egl/common/egl_g3d.h | 14 +++ .../state_trackers/egl/common/egl_g3d_image.c | 136 +++++++++++++++++++++ .../state_trackers/egl/common/egl_g3d_image.h | 41 +++++++ 4 files changed, 202 insertions(+), 3 deletions(-) create mode 100644 src/gallium/state_trackers/egl/common/egl_g3d_image.c create mode 100644 src/gallium/state_trackers/egl/common/egl_g3d_image.h diff --git a/src/gallium/state_trackers/egl/common/egl_g3d.c b/src/gallium/state_trackers/egl/common/egl_g3d.c index ddb1ef1..50774b0 100644 --- a/src/gallium/state_trackers/egl/common/egl_g3d.c +++ b/src/gallium/state_trackers/egl/common/egl_g3d.c @@ -36,6 +36,7 @@ #include "native.h" #include "egl_g3d.h" +#include "egl_g3d_image.h" #include "egl_st.h" /** @@ -615,6 +616,10 @@ egl_g3d_initialize(_EGLDriver *drv, _EGLDisplay *dpy, } #endif + dpy->Extensions.KHR_image_base = EGL_TRUE; + if (gdpy->native->get_param(gdpy->native, NATIVE_PARAM_USE_NATIVE_BUFFER)) + dpy->Extensions.KHR_image_pixmap = EGL_TRUE; + if (egl_g3d_add_configs(drv, dpy, 1) == 1) { _eglError(EGL_NOT_INITIALIZED, "eglInitialize(unable to add configs)"); goto fail; @@ -958,8 +963,8 @@ egl_g3d_swap_buffers(_EGLDriver *drv, _EGLDisplay *dpy, _EGLSurface *surf) /** * Find a config that supports the pixmap. */ -static _EGLConfig * -find_pixmap_config(_EGLDisplay *dpy, EGLNativePixmapType pix) +_EGLConfig * +egl_g3d_find_pixmap_config(_EGLDisplay *dpy, EGLNativePixmapType pix) { struct egl_g3d_display *gdpy = egl_g3d_display(dpy); struct egl_g3d_config *gconf; @@ -1011,7 +1016,7 @@ egl_g3d_copy_buffers(_EGLDriver *drv, _EGLDisplay *dpy, _EGLSurface *surf, if (!gsurf->render_surface) return EGL_TRUE; - gconf = egl_g3d_config(find_pixmap_config(dpy, target)); + gconf = egl_g3d_config(egl_g3d_find_pixmap_config(dpy, target)); if (!gconf) return _eglError(EGL_BAD_NATIVE_PIXMAP, "eglCopyBuffers"); @@ -1322,6 +1327,9 @@ _eglMain(const char *args) gdrv->base.API.BindTexImage = egl_g3d_bind_tex_image; gdrv->base.API.ReleaseTexImage = egl_g3d_release_tex_image; + gdrv->base.API.CreateImageKHR = egl_g3d_create_image; + gdrv->base.API.DestroyImageKHR = egl_g3d_destroy_image; + #ifdef EGL_MESA_screen_surface gdrv->base.API.CreateScreenSurfaceMESA = egl_g3d_create_screen_surface; gdrv->base.API.ShowScreenSurfaceMESA = egl_g3d_show_screen_surface; diff --git a/src/gallium/state_trackers/egl/common/egl_g3d.h b/src/gallium/state_trackers/egl/common/egl_g3d.h index 5d2d9c4..e3e55e4 100644 --- a/src/gallium/state_trackers/egl/common/egl_g3d.h +++ b/src/gallium/state_trackers/egl/common/egl_g3d.h @@ -34,6 +34,7 @@ #include "eglcontext.h" #include "eglsurface.h" #include "eglconfig.h" +#include "eglimage.h" #include "eglscreen.h" #include "eglmode.h" @@ -81,6 +82,14 @@ struct egl_g3d_config { const struct native_config *native; }; +struct egl_g3d_image { + _EGLImage base; + struct pipe_texture *texture; + unsigned face; + unsigned level; + unsigned zslice; +}; + struct egl_g3d_screen { _EGLScreen base; const struct native_connector *native; @@ -90,5 +99,10 @@ struct egl_g3d_screen { /* standard typecasts */ _EGL_DRIVER_STANDARD_TYPECASTS(egl_g3d) _EGL_DRIVER_TYPECAST(egl_g3d_screen, _EGLScreen, obj) +_EGL_DRIVER_TYPECAST(egl_g3d_image, _EGLImage, obj) + + +_EGLConfig * +egl_g3d_find_pixmap_config(_EGLDisplay *dpy, EGLNativePixmapType pix); #endif /* _EGL_G3D_H_ */ diff --git a/src/gallium/state_trackers/egl/common/egl_g3d_image.c b/src/gallium/state_trackers/egl/common/egl_g3d_image.c new file mode 100644 index 0000000..d701f9c9 --- /dev/null +++ b/src/gallium/state_trackers/egl/common/egl_g3d_image.c @@ -0,0 +1,136 @@ +/* + * Mesa 3-D graphics library + * Version: 7.8 + * + * Copyright (C) 2010 LunarG Inc. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included + * in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
