The entire interface is defined in libGLX.so and libEGL.so, including anything that passes through to libGLdispatch.so. Now, providing more direct control over the dispatch tables is something that's come up before. This is the current version of that: <a href="https://github.com/NVIDIA/libglvnd/pull/89">https://github.com/NVIDIA/libglvnd/pull/89</a> I don't have a good enough understanding of what Mesa needs out of it to be sure if that's sufficient, but if that overall design looks like it would work, then I'd be happy to dust it off and get it updated for the current EGL and GLX interfaces.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
