| | | | | | | | | | | The function _eglError() already explicitly returns EGL_FALSE, explicitly to simplify the callers. Make use of it. While EGL_FALSE is numerically identical to false, NULL, EGL_NO_FOO, storage is not the same so we cannot use it for "everything".

* egl/display: make platform detection thread-safeEric Engestrom2017-06-161-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Imagine there are 2 threads that both call _eglGetNativePlatform() simultaneously: - thread 1 completes the first "if (native_platform == _EGL_INVALID_PLATFORM)" check and is preempted to do something else - thread 2 executes the whole function, does "native_platform = _EGL_NATIVE_PLATFORM" and just before returning it's preempted - thread 1 wakes up and calls _eglGetNativePlatformFromEnv() which returns _EGL_INVALID_PLATFORM because no env vars are set, updates native_platform and then gets preempted again - thread 2 wakes up and returns wrong _EGL_INVALID_PLATFORM Solve this by doing the detection in a local var and only overwriting the global one at the end, if no other thread has updated it since. This means the platform detected in the thread might not be the platform returned by the function, but this is a different issue that will need to be discussed when this becomes possible.

| | | | | | | | | | | | | | My refactor missed the fact that `native_platform` is static. Add the proper guard around the detection code, as it might not be necessary, and only print the debug message when a detection was actually performed.

* egl/main: Enable Linux platform extensionsChad Versace2014-03-171-0/+72
| | | | | | | | | | | | | | | | 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 Versace2014-03-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* egl: Native Display autodetectionBenjamin Franzke2011-08-151-3/+97
| | | | | | | | | | | | | | | | | | | | | | | | 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?)
