Hi. I was also wondering about geometry shaders and the core profile with llvmpipe. I have cross compiled Mesa for Windows following the steps at qt- project, then tested the DLL with OpenGL Extensions Viewer. All I get is OpenGL 3.0, and no core profiles. I have tested versions 10.2.2, 10.2.3 and 10.3.0-devel with no luck so far. This message is as close as I have gotten to an answer, but it only seems to indicate that in Linux it just works (if you ask for a core profile). Is it supported in Windows? If so, is there something that needs to be done to enable the core profile?
