* mesa: GL_MESA_framebuffer_flip_y extension [v4]Fritz Koenig2018-07-272-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | Adds an extension to glFramebufferParameteri that will specify if the framebuffer is vertically flipped. Historically system framebuffers are vertically flipped and user framebuffers are not. Checking to see the state was done by looking at the name field. This adds an explicit field. v2: * updated spec language [for chadv] * correctly specifying ES 3.1 [for chadv] * refactor access to rb->Name [for jason] * handle GetFramebufferParameteriv [for chadv] v3: * correct _mesa_GetMultisamplefv [for kusmabite] v4: * update spec language [for chadv] * s/GLboolean/bool/g [for chadv] * s/InvertedY/FlipY/g [for chadv] * s/inverted_y/flip_y/g [for chadv] * assert changes [for chadv] Reviewed-by: Chad Versace <[email protected]>

* mesa: Implement a new GL_MESA_tile_raster_order extension.Eric Anholt2017-10-101-0/+5
| | | | | | | | | | | | | | The intent is to use this extension on vc4 to allow X11 to do overlapping CopyArea() within a pixmap without first blitting the pixmap to a temporary. With associated glamor patches, improves x11perf -copywinwin100 performance on a Raspberry Pi 3 from ~4700/sec to ~5130/sec, and is an even larger boost to uncomposited window movement performance (most copywinwin100 copies don't overlap). v2: Fix glIsEnabled() on the new enums. v3: Drop the local spec since I'm upstreaming the spec.

| | | | | | | | | | | | | When publishing this spec on the OpenGL ES registry, Jon Leech noticed that it didn't actually mention what the ES dependencies and interactions were. I looked at extensions_table.h and noted that we expose it in ES 3.0 contexts, and he added the obvious spec texts.

* 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.

NOTE: This patch regresses GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY cases of the copyteximage piglit test. The test is incorrectly using texture arrays with fixed function while only requiring the GL_EXT_texture_array extension.

* 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.
