* egl: Emit correct error when robust context creation failsChad Versace2016-12-271-12/+26
| | | | | | | | | | | | | | | | | Fixes dEQP-EGL.functional.create_context_ext.robust_* on Intel with GBM. If the user sets the EGL_CONTEXT_OPENGL_ROBUST_ACCESS_BIT_KHR in EGL_CONTEXT_FLAGS_KHR when creating an OpenGL ES context, then EGL_KHR_create_context spec requires that we unconditionally emit EGL_BAD_ATTRIBUTE because that flag does not exist for OpenGL ES. When creating an OpenGL context, the spec requires that we emit EGL_BAD_MATCH if we can't support the request; that error is generated in the egl_dri2 layer where the driver capability is actually checked.

| | | | | | | | | | | | MESA_configless_context does not specify the interaction with QueryContext at all, and the code to generate an error in this case predates the Mesa extension. Since EGL_NO_CONFIG_{KHR,MESA} are numerically identical there's no way to distinguish which one the application asked for, so use the KHR behaviour.

* EGL: Combine the GL and GLES current contexts (v2)Kyle Brenneman2016-09-071-27/+4
| | | | | | | | | | | | | | | | | | | | | | Only keep track of a single current context, instead of separate contexts for GL and GLES. In EGL 1.4 (and 1.5), EGL_OPENGL_API and EGL_OPENGL_ES_API are supposed to be interchangeable for all purposes except for eglCreateContext. The _EGLThreadInfo::CurrentContexts array is now a single pointer to the current context, which may be a GL or GLES context. In addition, it now keeps track of the current API as an enum instead of an index. eglMakeCurrent will now replace the current context, regardless of which client API is used for for the current and new contexts. It no longer checks for a conflicting context. In addition, calling eglMakeCurrent with EGL_NO_CONTEXT will now release the current context regardless of the current API. v2: Rebased against master (Adam Jackson) Reviewed-by: Adam Jackson <[email protected]>

* egl: improve attribute checking for eglCreateContextFrank Binns2015-08-131-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | The EGL 1.4 spec states for eglCreateContext: "attribute EGL_CONTEXT_CLIENT_VERSION is only valid when the current rendering API is EGL_OPENGL_ES_API" Additionally, if the EGL_KHR_create_context EGL extension is supported (this is mandatory in EGL 1.5) then the EGL_CONTEXT_MAJOR_VERSION_KHR, which is an alias for EGL_CONTEXT_CLIENT_VERSION, and EGL_CONTEXT_MINOR_VERSION_KHR attributes are also accepted by eglCreateContext with the extension spec stating: "The values for attributes EGL_CONTEXT_MAJOR_VERSION_KHR and EGL_CONTEXT_MINOR_VERSION_KHR specify the requested client API version. They are only meaningful for OpenGL and OpenGL ES contexts, and specifying them for other types of contexts will generate an error." Add the necessary checks against the extension and rendering APIs when validating these attributes as part of eglCreateContext.

| | | | | | | | | | | | | | | | | | | | We would generate EGL_BAD_CONFIG because _eglGetContextAPIBit returns zero for the combination of EGL_OPENGL_ES_API and a major version > 3. By just returning zero, the caller can't tell the difference between a bad version (which should generate EGL_BAD_MATCH) and a bad API (which should generate EGL_BAD_CONFIG). This patch causes us to filter out major versions > 3 at a point where we can generate the correct error.

* Add the EGL_MESA_configless_context extensionNeil Roberts2014-03-121-4/+16
| | | | | | | | | | | | | | | | | | | | 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.

* egl/dri2: Add plumbing for EGL_OPENGL_ES3_BIT_KHRChad Versace2013-01-151-1/+3

According to the EGL_KHR_create_context spec, it is illegal to call eglCreateContext(EGL_CONTEXT_MAJOR_VERSION_KHR=3) with a config whose EGL_RENDERABLE_TYPE does not contain the EGL_OPENGL_ES3_BIT_KHR. The pertinent portion of the spec is quoted below; the key word is "respectively". * If <config> is not a valid EGLConfig, or does not support the requested client API, then an EGL_BAD_CONFIG error is generated (this includes requesting creation of an OpenGL ES 1.x, 2.0, or 3.0 context when the EGL_RENDERABLE_TYPE attribute of <config> does not contain EGL_OPENGL_ES_BIT, EGL_OPENGL_ES2_BIT, or EGL_OPENGL_ES3_BIT_KHR respectively). To create this patch, I searched for all the ES2 bit plumbing by calling `git grep "ES2_BIT\|DRI_API_GLES2" src/egl`, and then at each location added a case for ES3.
