The latter seems to have diminished and my attempts to get it back on board have been shot down, sort of speak. The original issue: Ajax would be one of the better people to answer this, but the gist is that there can/could be than one provider* for the entry points - which one gets picked is (implicitly) determined by the specific DRI loader. Thus if we link against the "wrong" provider things will end up badly. At the same time - DRI loader/driver interface is (and was last time I've tried) stable. So if one is to use a) old libGL.so which provides the symbols and b) new DRI module (linked against libglapi.so) you get symbol collision. If we are to break the stability we should consider: - DRI drivers which don't receive much love these days, don't support latest version of __DRI_EXTENSION v19 or are missing the some extensions all together. - dri1,2,3 capability/support - Support for old server(s) - eg. make libEGL/x11 require DRI2 minor >= 3 - Dropping {barely ,un}used codepaths - eg. loaders mandate __DRI_DRI2 >= 4 and similar on the driver side. - And last but not least - reuse GLVND dispatch. For this we would need to convince Kyle that GLdisplatch.so can be accessible by vendors and it gets some ABI stability (note the GLVND libraries in general seem ABI unstable).</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>
