* egl_dri: rework dri extension handlingEmil Velikov2014-04-282-11/+12

* dri_interface: Update __DRItexBufferExtensionRec to version 3Emil Velikov2014-04-281-6/+7
| | | | | | | | | | | | | | | | | | | | With commit e59fa4c46c8("dri2: release texture image.") we updated the extension without bumping the version number. The patch itself added an interface required to enable texture_from_pixmap on certain platforms. The new code was effectively never build, as it depended on __DRI_TEX_BUFFER_VERSION >= 3, which never came to be in upstream mesa. This commit bumps the version number, drops the __DRI_TEX_BUFFER_VERSION checks and resolves all the build conflicts. Additionally it add a version check as egl and dri3, as require version 2 of the extension which does not have the releaseTexBuffer hook.

* egl/main: Stop using EGLNative types internallyChad Versace2014-03-177-32/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/dri2: Consolidate eglTerminateChad Versace2014-03-172-40/+24
| | | | | | | | | | | | | | | | | | | | egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays. The Wayland platform implemented its own dri2_wl_terminate(), which was nearly a copy of the common one. To implement the EGL platform extensions, we either need to dispatch eglTerminate per display or define a common implementation for all platforms. This patch chooses consolidation. It removes dri2_wl_terminate() by folding it into the common dri2_terminate(). It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and the switch statement because, unlike DRM and X11, Wayland's terminator performed action even when EGL didn't own the native display. In the inversion, I replaced `disp->PlatformDisplay == NULL` with `dri2_dpy->own_device` because the two expressions are synonymous, but the latter's meaning is clearer.

| | | | | | | | | | | | | | | | | | | | Each of the egl_dri2 platforms (except Android) prefix their function names with "dri2", not "dri2_${platform}". This means many function names have three separate definitions in the egl_dri2 directory: one in each of platform_drm.c, platform_wayland.c, and platform_x11.c. For example, each of the three files defines dri2_create_window_surface(). The name collisions make it difficult to review patches for correctness ("Is this patch hunk calling a platform_x11 function or a global egl_dri2 function?"), complicate debugging, and confuse code navigation tools. For each function in platform_x11.c prefixed with 'dri2', this patch changes its prefix to 'dri2_x11'. Likewise for platform_drm.c and 'dri2_drm'; and platform_wayland.c and 'dri2_wl'.

* Add the EGL_MESA_configless_context extensionNeil Roberts2014-03-121-0/+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.

* wayland: Add support for eglSwapIntervalNeil Roberts2013-12-073-40/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* wayland: Block for the frame callback in get_back_bo not dri2_swap_buffersNeil Roberts2013-12-071-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider a typical game-style main loop which might be like this: while (1) { draw_something(); eglSwapBuffers(); } In this case the game is relying on eglSwapBuffers to throttle to a sensible frame rate. Previously this game would end up using three buffers even though it should only need two. This is because Mesa decides whether to allocate a new buffer in get_back_bo which would be before it has tried to read any events from the compositor so it wouldn't have seen any buffer release events yet. This patch just moves the block for the frame callback to get_back_bo. Typically the compositor will send a release event immediately after one of the attaches so if we block for the frame callback here then we can be sure to have completed at least one roundtrip and received that release event after attaching the previous buffer before deciding whether to allocate a new one. dri2_swap_buffers always calls get_back_bo so even if the client doesn't render anything we will still be sure to block to the frame callback. The code to create the new frame callback has been moved to after this call so that we can be sure to have cleared the previous frame callback before requesting a new one.
* wayland: Add an extension to create wl_buffers from EGLImagesNeil Roberts2013-12-041-0/+78
| | | | | | | | | | | | | | | | | | 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/wayland: Damage INT32_MAX x INT32_MAX region for eglSwapBuffersKristian Høgsberg2013-12-041-2/+2
| | | | | | | | | | | | | | | | If we're not using EGL_EXT_swap_buffers_with_damage, we have to damage the full extent. EGL operates on buffer coordinates, but wl_surface.damage takes surface coordinates. EGL doesn't know the buffer transformation (rotated or scaled) and can't post accurate damage in surface coordinates. The damage event however is clipped to the surface extents so we can just damage the maximum rectangle. In case of EGL_EXT_swap_buffers_with_damage, the application knows the buffer transform and is expected to pass in rectangles in surface space. https://bugs.freedesktop.org/show_bug.cgi?id=70250 Cc: "10.0" [email protected]
