Summary: [r600g, wine] sync/fenc GL extension missing Product: DRI Version: DRI CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: liquid.acid@gmx.net
Hello,
I noticed that r600g currently neither implements NV_fence nor ARB_sync. Wine needs at least one of these extensions (I think ARB_sync is preferred) to emulate event queries for Direct3D.
Currently this results in lots of errors: err:d3d:wined3d_event_query_test Event query created despite lack of GL support err:d3d:IWineD3DEventQueryImpl_GetData The GL event query failed, returning D3DERR_INVALIDCALL
So this is more a feature request...
Greets, Tobias

--- Comment #2 from Tobias Jakobi liquid.acid@gmx.net 2011-02-02 02:03:49 PST --- This is interesting, since ARB_sync is implemented in the i965 classic driver, which only advertises GL 2.1 support.

I think that bit in the ARB_sync spec is incorrect. I believe the extension is written against the OpenGL 3.1 spec, but I don't believe that 3.1 is actually required. As Tobias mentions in comment #2, we implement this extension in the i965 driver without any problems. We didn't encounter any odd interactions or dependencies along the way.
