From af977b53826695afcdcfe900816a93671aec00f5 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sun, 10 Oct 2010 20:15:06 +0800 Subject: [PATCH] st/egl: Add native_display_buffer interface. The interface is a wrapper to pipe_screen::resource_from_handle and pipe_screen::resource_get_handle. A winsys handle is platform-dependent. --- src/gallium/state_trackers/egl/common/native.h | 2 + .../state_trackers/egl/common/native_buffer.h | 59 ++++++++++++++++++++++ 2 files changed, 61 insertions(+) create mode 100644 src/gallium/state_trackers/egl/common/native_buffer.h diff --git a/src/gallium/state_trackers/egl/common/native.h b/src/gallium/state_trackers/egl/common/native.h index 5ee7956..3886ca2 100644 --- a/src/gallium/state_trackers/egl/common/native.h +++ b/src/gallium/state_trackers/egl/common/native.h @@ -38,6 +38,7 @@ extern "C" { #endif +#include "native_buffer.h" #include "native_modeset.h" /** @@ -190,6 +191,7 @@ struct native_display { EGLNativePixmapType pix, const struct native_config *nconf); + const struct native_display_buffer *buffer; const struct native_display_modeset *modeset; }; diff --git a/src/gallium/state_trackers/egl/common/native_buffer.h b/src/gallium/state_trackers/egl/common/native_buffer.h new file mode 100644 index 0000000..5c29ab9 --- /dev/null +++ b/src/gallium/state_trackers/egl/common/native_buffer.h @@ -0,0 +1,59 @@ +/* + * Mesa 3-D graphics library + * Version: 7.9 + * + * 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.
