* egl/dri2: set WL_bind_wayland_display in a consistent wayEmil Velikov2016-10-141-0/+24
| | | | | | | | | | | | | | Introduce a helper and use it throughout the platform code. This allows us to reduce the amount of ifdef(s) and (potentially) use kms_swrast_dri.so for !drm platforms (namely wayland and x11). Note: in the future as other platforms (android, surfaceless) support the extension they can reuse the helper. v2: Rebase, check for device_name.

* egl/dri2: Add reference count for dri2_egl_displayNicolas Boichat2016-07-281-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | android.opengl.cts.WrapperTest#testGetIntegerv1 CTS test calls eglTerminate, followed by eglReleaseThread. A similar case is observed in this bug: https://bugs.freedesktop.org/show_bug.cgi?id=69622, where the test calls eglTerminate, then eglMakeCurrent(dpy, NULL, NULL, NULL). With the current code, dri2_dpy structure is freed on eglTerminate call, so the display is not initialized when eglReleaseThread calls MakeCurrent with NULL parameters, to unbind the context, which causes a a segfault in drv->API.MakeCurrent (dri2_make_current), either in glFlush or in a latter call. eglTerminate specifies that "If contexts or surfaces associated with display is current to any thread, they are not released until they are no longer current as a result of eglMakeCurrent." However, to properly free the current context/surface (i.e., call glFlush, unbindContext, driDestroyContext), we still need the display vtbl (and possibly an active dri dpy connection). Therefore, we add some reference counter to dri2_egl_display, to make sure the structure is kept allocated as long as it is required. One drawback of this is that eglInitialize may not completely reinitialize the display (if eglTerminate was called with a current context), however, this seems to meet the EGL spec quite well, and does not permanently leak any context/display even for incorrectly written apps.

* egl/main: Stop using EGLNative types internallyChad Versace2014-03-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* wayland: Add support for eglSwapIntervalNeil Roberts2013-12-071-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Wayland EGL platform now respects the eglSwapInterval value. The value is clamped to either 0 or 1 because it is difficult (and probably not useful) to sync to more than 1 redraw. The main change is that if the swap interval is 0 then Mesa won't install a frame callback so that eglSwapBuffers can be executed as often as necessary. Instead it will do a sync request after the swap buffers. It will block for sync complete event in get_back_bo instead of the frame callback. The compositor is likely to send a release event while processing the new buffer attach and this makes sure we will receive that before deciding whether to allocate a new buffer. If there are no buffers available then instead of returning with an error, get_back_bo will now poll the compositor by repeatedly sending sync requests every 10ms. This is a last resort and in theory this shouldn't happen because there should be no reason for the compositor to hold on to more than three buffers. That means whenever we attach the fourth buffer we should always get an immediate release event which should come in with the notification for the first sync request that we are throttled to. When the compositor is directly scanning out from the application's buffer it may end up holding on to three buffers. These are the one that is is currently scanning out from, one that has been given to DRM as the next buffer to flip to, and one that has been attached and will be given to DRM as soon as the previous flip completes. When we attach a fourth buffer to the compositor it should replace that third buffer so we should get a release event immediately after that. This patch therefore also changes the number of buffer slots to 4 so that we can accomodate that situation. If DRM eventually gets a way to cancel a pending page flip then the compositors can be changed to only need to hold on to two buffers and this value can be put back to 3. This also moves the vblank configuration defines from platform_x11.c to the common egl_dri2.h header so they can be shared by both platforms.
