I'm looking at these on my phone, so perhaps I missed it - do you ever end up turning them on, or is that left to later series? <div class="gmail_extra"> <div class="gmail_quote">On Aug 1, 2016 12:30 PM, "Kenneth Graunke" <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Also update _mesa_has_tessellation to know about the new extensions. For now, these are dummy_false, to avoid turning on the extension until everything's in place. Eventually, we'll move them over to the "ARB_tessellation_shader" bit so that any drivers supporting both the desktop extension and ES 3.1 get the feature.
