* specs: Remove GLX_RENDERER_ID_MESA from GLX_MESA_query_rendererAdam Jackson2018-12-181-19/+0
| | | | | | | | | | | | | | | | | | | | | | This has not even had an attempt at implementation. If you asked for renderer 0 - which, the spec implies, should always work - then dri2_convert_glx_attribs would fail, we'd silently fall back to creating an indirect context, and xserver would also not recognize the attribute and would throw BadValue at you. The API would be difficult to use in any case, since there's no way to enumerate how many renderers the screen has. I'd be tempted to add that by defining: glXQueryRendererIntegerMESA(dpy, screen, /* renderer = */ -1, 0, &value); to return the number of renderers, but a new entrypoint might be cleaner. Still, better to not specify it at all than to lie about it. Reviewed-by: Emil Velikov <[email protected]> Signed-off-by: Adam Jackson <[email protected]>
* specs: Remove GLES profile interaction text from GLX_MESA_query_rendererAdam Jackson2018-12-181-12/+0
| | | | | | | | | | | | | | | | In one place we say, if GLES isn't supported then the profile version will be 0.0. Then later we say, if the GLES profile extension isn't supported then GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not mentioned in the spec. A strict reading of the latter would mean that GLX_RENDERER_OPENGL_ES_PROFILE_VERSION_MESA is not a recognized token, and the query should instead return False. The implementation does not check for the GLES profile extensions, and the additional complexity doesn't seem worth it. Removing the interaction text makes the spec match the implementation.

* Add the EGL_MESA_configless_context extensionNeil Roberts2014-03-121-0/+125
| | | | | | | | | | | | | | | | | | | | 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 an extension to create wl_buffers from EGLImagesNeil Roberts2013-12-041-0/+101
| | | | | | | | | | | | | | | | | | 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.
