Bug ID: 100865 Summary: Unigine Heaven 4 lockups GPU in wireframe mode Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: marvin24@gmx.de QA Contact: dri-devel@lists.freedesktop.org
Created attachment 131115 --> https://bugs.freedesktop.org/attachment.cgi?id=131115&action=edit dmesg output
launched UH4 on RS880 / Kernel 4.10.10 with mesa git demo runs well until you press "F2" in order to activate wireframe mode, which causes GPU lockups
tested mesa: 12, 13, 17, 17.1 and git - all same.

--- Comment #1 from Dieter Nützel Dieter@nuetzel-hh.de --- Hello Marc,
can you please verify, that it is a _combination_ of wireframe _and_ tessellation? I've got that for ages with r600g, RV730 (HD 4650, 1GB, AGP) and NI/Turks XT (HD 6670, 2 GB PCIe). As 'Heaven' (UH4) start 'normally' with tessellation enabled and 'you' press 'F2' (enable wireframe) it could result in GPU lockup. So please start 'Heaven', press 'F3' (disable tessellation) and last press 'F2' (enable wireframe). This 'version' works fine for me. It seems to be a combination of both. But my systems mostly recover from the GPU lockup. W'll try to get a new backtrace, soon.
Tessellation is so awfully _slow_ (hardware or 'only' software implemantation) that I think we have to look/point, there.
Bas (Radv) worked on radeonsi tessellation improvements. See related links: https://www.phoronix.com/scan.php?page=news_item&px=R600g-Tessellation-L...

Second: I ran all the time with MESA_GL_VERSION_OVERRIDE=4.1COMPAT and 'Heaven' show display corruption (missing parts), but wireframe works. If I toggle tessellation (F3) missing parts arise but without tessellation, as expected. So for 'Heaven' I have to disable MESA_GL_VERSION_OVERRIDE and get the above boom (GPU lockup).
=> tessellation / wireframe correlation
'All' old and Mesa git, Kernel 4.11-rc8 (and former)
Greetings, Dieter

--- Comment #2 from Marc Dietrich marvin24@gmx.de --- My card does not support tess and I also disabled it in the launcher. Also my card is only GL3.3.

--- Comment #3 from Marc Dietrich marvin24@gmx.de --- I ran apitrace on heaven_x64 and now the thing doesn't crash anymore :-( So maybe commands come to fast in wireframe mode and need some fence/sync point?
