With R600_DEBUG=nohyperz R600_DEBUG=nosb, gsraytrace also freezes the GPU

Hello Lukáš,

as you own a Radeon HD 3400 RV620

'semilar' to my RV730 the 'gsraytrace' GPU hang is NOT soveld with current GIT. I'll update my bug report (Bug 83319), soon.

For EG+ (Bug 91865) this is _fixed_ by 'accident' in Mesa git since:

commit 2239f3eaff5c72c4cb1d4a5be97feb4af3d08d25 Author: Dave Airlie airlied@redhat.com Date: Mon Nov 30 15:48:22 2015 +1000

r600/shader: emit tessellation factors to GDS at end of TCS.

When we are finished the shader, we read back all the tess factors from LDS and write them to special global memory storage using GDS instructions.

This also handles adding NOP when GDS or ENDLOOP end the TCS.

Signed-off-by: Dave Airlie airlied@redhat.com

I'll have to talk with Dave and Marek what is different for R600/R700 and EG+ and what should I try next.

Created attachment 121050 [details] Output from apitrace when replaying the trace

I have tried to replay the trace with nouveau and it did not crash and produced attached output.

How do you did it?

If I run it on NI/Turks XT (HD 6670) for which 'gsraytrace' is fixed, it terminates in fractions of a second and print nothing.

apitrace replay gsraytrace.trace Rendered 0 frames in 0.101416 secs, average of 0 fps
