Observed on mesa-84b4372 with i965. There is no bugzilla category for EGL, so I'm placing this bug in the GLX category. How to reproduce ----------------- On i965, call eglCreateContext() with EGL_CONTEXT_MAJOR_VERSION_KHR/EGL_CONTEXT_MINOR_VERSION_KHR set to 3.2. Context creation will fail because i965 does not yet support GL 3.2. Afterwards, eglGetError() returns EGL_SUCCESS. For a standalone testcase that reproduces the problem, run the example program "gl_basic" found in waffle-7d76755. Run it as `gl_basic x11_egl gl 3.2. Expected behavior ----------------- eglGetError() should return EGL_BAD_MATCH. From the EGL_KHR_create_context spec: * If an OpenGL context is requested and the values for attributes EGL_CONTEXT_MAJOR_VERSION_KHR and EGL_CONTEXT_MINOR_VERSION_KHR, when considered together with the value for attribute EGL_CONTEXT_OPENGL_FORWARD_COMPATIBLE_BIT_KHR, specify an OpenGL version and feature set that are not defined, than an EGL_BAD_MATCH error is generated. Diagnosis --------- In eglCreateContext, no error code is set when drv->API.CreateContext fails.
