Hardware: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff) So I'm using radeonsi with PRIME and latest mesa git, recent llvm 3.6 revision. I foolishly deleted the old Unreal Engine Demos so I can't make a recent test, but they worked decently last time I checked. Now the Unreal Demos have been updated to UE 4.5: https://wiki.unrealengine.com/Linux_Demos "Tappy Chicken": Works fine on intel and radeonsi. "Shooter Game": Works fine on intel, but shows only game HUD and text on radeonsi "Light Room Interior Day Demo": Works fine on intel but is completely black on radeonsi Apitrace says the only problems are: $ DRI_PRIME=1 glretrace Lightroominteriorday.trace 882: glDebugOutputCallback: Medium severity API other issue 1, FBO incomplete: no attachments [-1] 0 4096 glXSwapIntervalMESA(interval = 0) = 0 4096: warning: unsupported glXSwapIntervalMESA call context mis-match in pipe_sampler_view_release() Rendered 191 frames in 13.88 secs, average of 13.7608 fps Here is the trace from which I got the above output: http://haagch.frickel.club/files/Lightroominteriorday.trace.xz It renders fine on intel, but only black on radeonsi. (Careful: When creating a trace on intel, the engine will use glCopyImageSubData which is not supported on radeonsi. When creating a trace on radeonsi it will not.)
If your llvm is new enough could be - https://bugs.freedesktop.org/show_bug.cgi?id=86432
(In reply to Andy Furniss from comment #1) > If your llvm is new enough could be - > > https://bugs.freedesktop.org/show_bug.cgi?id=86432 Light Room Interior Day Demo works for me now, so assuming that was it. *** This bug has been marked as a duplicate of bug 86432 ***
I can confirm, it renders now. Thanks for the info.
