It is just Mesa that never reports an EGLConfig using the format when i915/i965 is in use.
But we still allow EGLImageKHR to be created from buffers in the format. It can be used with glEGLImageTargetTexture2D and this usage is quite common. But when the EGLImageKHR is used with glEGLImageTargetRenderbufferStorage, GL_INVALID_OPERATION should be generated (which I missed). -- o...@lunarg.com _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
