* egl: Check for NULL native_window in eglCreateWindowSurfaceSinclair Yeh2014-06-031-0/+4
| | | | | | | | | | | | | | | We have customers using NULL as a way to test the robustness of the API. Without this check, EGL will segfault trying to dereference dri2_surf->wl_win->private because wl_win is NULL. This fix adds a check and sets EGL_BAD_NATIVE_WINDOW v2: Incorporated feedback from idr - moved the check to a higher level function.

* egl/main: Fix eglMakeCurrent when releasing context from current thread.Beren Minor2014-06-021-2/+6
| | | | | | | | | | | | | | EGL 1.4 Specification says that eglMakeCurrent(display, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT) can be used to release the current thread's ownership on the surfaces and context. MESA's egl implementation was only accepting the parameters when the KHR_surfaceless_context extension is supported. [chadv] Add quote from the EGL 1.4 spec.

* egl: Add EGL_CHROMIUM_sync_control extension.Sarah Sharp2014-05-201-0/+23
| | | | | | | | | | | | | | | | | | | | | Chromium defined a new GL extension (that isn't registered with Khronos). We need to add an EGL extension for it, so we can migrate ChromeOS on Intel systems to use EGL instead of GLX. http://git.chromium.org/gitweb/?p=chromium/src/third_party/khronos.git;a=commitdiff;h=27cbfdab35c601f70aa150581ad1448d0401f447 The EGL_CHROMIUM_sync_control extension is similar to the GLX extension OML_sync_control, but only defines one function, eglGetSyncValuesCHROMIUM, which is equivalent to glXGetSyncValuesOML. http://www.opengl.org/registry/specs/OML/glx_sync_control.txt Signed-off-by: Sarah Sharp <[email protected]> Reviewed-by: Chad Versace <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Cc: Jamey Sharp <[email protected]> Cc: Ian Romanick <[email protected]> Cc: Stéphane Marchesin <[email protected]>
* egl/main: Enable Linux platform extensionsChad Versace2014-03-171-22/+110
| | | | | | | | | | | | | | | | Enable EGL_EXT_platform_base and the Linux platform extensions layered atop it: EGL_EXT_platform_x11, EGL_EXT_platform_wayland, and EGL_MESA_platform_gbm. Tested with Piglit's EGL_EXT_platform_base tests under an X11 session. To enable running the Wayland and GBM tests, windowed Weston was running and the kernel had render nodes enabled. I regression tested my EGL_EXT_platform_base patch set with Piglit on Ivybridge under X11/EGL, standalone Weston, and GBM with rendernodes. No regressions found.

* egl/main: Stop using EGLNative types internallyChad Versace2014-03-171-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Internally, much of the EGL code uses EGLNativeDisplayType, EGLNativeWindowType, and EGLPixmapType. However, the EGLNative type often does not match the variable's actual type. The concept of EGLNative types are a bad match for Linux, as explained below. And the EGL platform extensions don't use EGLNative types at all. Those extensions attempt to solve cross-platform issues by moving the EGL API away from the EGLNative types. The core of the problem is that eglplatform.h can define each EGLNative type once only, but Linux supports multiple EGL platforms. To work around the problem, Mesa's eglplatform.h contains multiple definitions of each EGLNative type, selected by feature macros. Mesa expects EGL clients to set the feature macro approrpiately. But the feature macros don't work when a single codebase must be built with support for multiple EGL platforms, *such as Mesa itself*. When building libEGL, autotools chooses the EGLNative typedefs based on the first element of '--with-egl-platforms'. For example, '--with-egl-platforms=x11,drm,wayland' defines the following: typedef Display* EGLNativeDisplayType; typedef Window EGLNativeWindowType; typedef Pixmap EGLNativePixmapType; Clearly, this doesn't work well for Wayland and GBM. Mesa works around the problem by casting the EGLNative types to different things in different files. For sanity's sake, and to prepare for the EGL platform extensions, this patch removes from egl/main and egl/dri2 all internal use of the EGLNative types. It replaces them with 'void*' and checks each explicit cast with a static assertion. Also, the patch touches egl_gallium the minimal amount to keep it compatible with eglapi.h.

* Add the EGL_MESA_configless_context extensionNeil Roberts2014-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | This extension provides a way for an application to render to multiple surfaces with different buffer formats without having to use multiple contexts. An EGLContext can be created without an EGLConfig by passing EGL_NO_CONFIG_MESA. In that case there are no restrictions on the surfaces that can be used with the context apart from that they must be using the same EGLDisplay. _mesa_initialze_context can now take a NULL gl_config which will mark the context as ‘configless’. It will memset the visual to zero in that case. Previously the i965 and i915 drivers were explicitly creating a zeroed visual whenever 0 is passed for the EGLConfig. Mesa needs to be aware that the context is configless because it affects the initial value to use for glDrawBuffer. The first time the context is bound it will set the initial value for configless contexts depending on whether the framebuffer used is double-buffered.

* eglCreateContext: Remove the check for whether config == 0Neil Roberts2014-03-121-5/+2
| | | | | | | | | | | | | | | | In eglCreateContext there is a check for whether the config parameter is zero and in this case it will avoid reporting an error if the EGL_KHR_surfacless_context extension is supported. However there is nothing in that extension which says you can create a context without a config and Mesa breaks if you try this so it is probably better to leave it reporting an error. The original check was added in b90a3e7d8b1bc based on the API-specific extensions EGL_KHR_surfaceless_opengl/gles1/gles2. This was later changed to refer to EGL_KHR_surfacless_context in b50703aea5. Perhaps the original extensions specified a configless context but the new one does not. Reviewed-by: Kristian Høgsberg <[email protected]>

* wayland: Add an extension to create wl_buffers from EGLImagesNeil Roberts2013-12-041-0/+25
| | | | | | | | | | | | | | | | | | This adds an extension called EGL_WL_create_wayland_buffer_from_image which adds the following single function: struct wl_buffer * eglCreateWaylandBufferFromImageWL(EGLDisplay dpy, EGLImageKHR image); The function creates a wl_buffer which shares its contents with the given EGLImage. The expected use case for this is in a nested Wayland compositor which is using subsurfaces to present buffers from its clients. Using this extension it can attach the client buffers directly to the subsurface without having to blit the contents into an intermediate buffer. The compositing can then be done in the parent compositor. The extension is only implemented in the Wayland EGL platform because of course it wouldn't make sense anywhere else.

* egl: Native Display autodetectionBenjamin Franzke2011-08-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | EGL doesnt define howto manage different native platforms. So mesa has a builtime configurable default platform, whith non-standard envvar (EGL_PLATFORM) overwrites. This caused unneeded bugreports, when EGL_PLATFORM was forgotten. Detection is grouped into basic types of NativeDisplays (which itself needs to be detected). The final decision is based on characteristcs of these basic types: File Desciptor based platforms (fbdev): - fstat(2) to check for being a fd that belongs to a character device - check kernel subsystem (todo) Pointer to structuctures (x11, wayland, drm/gbm): - mincore(2) to check whether its valid pointer to some memory. - magic elements (e.g. pointers to exported symbols): o wayland display stores interface type pointer (first elm.) o gbm stores pointer to its constructor (first elm.) o x11 as a fallback (FIXME?)

* egl: Rework driver loading.Chia-I Wu2010-07-061-40/+8
| | | | | | | | | | | | | | | Driver loading is now splitted into two stages. In the first stage, an _EGLModule is created for each driver: user driver, default drivers, and all files in the search directories that start with "egl_". Modules are not loaded at this stage. In the second stage, each module is loaded to initialize a display. The process stops at the first module that can initialize the display. If eglGetProcAddress is called before eglInitialize, the same code path will be taken to find the first module that supports EGL_DEFAULT_DISPLAY. Because we do not want to initialize the display, drv->Probe is used instead in this case.

* egl: Allow a prioritized list of default driversKristian Høgsberg2010-05-131-6/+8
| | | | | | | | | | | | | | When there is no user driver or any matching display drivers we fall back to the default driver. This patch lets us have a list of default drivers instead of just one. The drivers are loaded in turn and we attempt to initialize the display. If it fails we unload the driver and move on to the next one. Compared to the display driver mechanism, this avoids loading a number of drivers and then only using one. Also, we call Initialize to see if the driver will work instead of relying on Probe. To know for sure that a driver will work, Probe really have to do a full Initialize, so we will just use Initialize directly.
